About Veritas CommandCentral Storage
What’s new in CommandCentral Storage 5.1
CommandCentral Storage 5.1 contains and builds upon CommandCentral Storage
5.0 functionality, providing several new features.
Management and discovery
CommandCentral Storage 5.1 introduces the following management and discovery
features.
Enhanced agentless discovery of storage resources
If you do not install the CommandCentral managed host on hosts in your storage
network, the CommandCentral Management Server can discover those hosts and
their connections to storage resources through agentless discovery.
The process involves creating a user-created host in order to associate the
unidentified adapter (HBA) discovered through switch discovery to the host to
which it connects. In previous versions of CommandCentral, you could do this
one host at a time. Now, CommandCentral 5.1 provides you with the ability to
create multiple hosts at once and to automate the process by creating rules and
importing information from a CSV file.
For more information about this feature, see the CommandCentral Storage User’s
Guide.
Detection of configuration related changes to storage arrays
In CommandCentral Storage 5.0 MP1, explorers initiate discovery of devices based
on the explorer’s polling interval. The polling interval is the amount of time that
the explorer waits to initiate discovery of the device. For example, the polling
interval might be 180 minutes.
In CommandCentral Storage 5.1, explorers continue to initiate discovery of devices
based on the explorer’s polling interval; however, for certain array explorers, you
can also enable change detection. When you enable change detection, explorers
listen to SNMP traps or frequently poll storage arrays—for example, every 15
minutes—in order to detect configuration related changes to that array—for
example, masking changes. When the explorer detects configuration related
changes to the storage array, the explorer initiates a full discovery of the array.
For example, if you enable change detection for EMC CLARiiON storage arrays,
by default, the explorer listens for SNMP traps from CLARiiON storage arrays.
When the explorer detects changes, it initiates discovery of the array. Because
the explorer discovers the changes in near real-time, CommandCentral Storage
can provide you with more up-to-date information about the storage array. In
contrast, if you do not enable change detection, discovery occurs only when the
10 Getting started with the CommandCentral family
About Veritas CommandCentral Storage
explorer polls the storage array using the polling interval—for example, a polling
interval of 180 minutes.
Change detection is available for the following storage arrays:
■
■
■
■
■
EMC CLARiiON
EMC Symmetrix
Hitachi HiCommand
HP EVA
NetApp unified storage devices
For information about enabling change detection, see the CommandCentral
Hardware and Software Configuration Guide.
Improved Data Module file scanning
In CommandCentral Storage 5.0 MP1, the Data Module file scanner determines a
file’s size by its logical size. Now, in CommandCentral Storage 5.1, the file scanner
also collects a file’s physical size. A file’s physical size provides you with a more
accurate account of space consumption over the logical size. You can use the Data
Module Importer settings and Data Module rules to specify whether you want
summary reports that report on directory size, user consumption, file type usage,
and aging data to display a file’s size by its logical size or physical size.
Additionally, you can drill down into detail reports to display both the logical size
and physical size.
For more information, see the CommandCentral Administrator’s Guide.
Discovery of device groups and composite groups for EMC Symmetrix
storage arrays
CommandCentral Storage now discovers the name of the device groups and
composite groups to which devices from EMC Symmetrix storage arrays belong.
The group names appear when you view an EMC Symmetrix storage array’s Devices
pane.
Discovery of replication objects for HP EVA storage arrays
CommandCentral Storage now discovers the following replication objects for HP
EVA storage arrays:

About Veritas CommandCentral Storage
Added support for discovery of ESX servers through the VMware
Infrastructure SDK
In CommandCentral Storage 5.1, you can now configure discovery of ESX servers
through the VMware Infrastructure SDK (VI SDK). This allows you to discover
individual ESX servers through VI SDK or a VirtualCenter that manages multiple
ESX servers through VI SDK.
For information about configuring discovery through VI SDK, see the
CommandCentral Hardware and Software Configuration Guide.
Sybase ASE 15 support
CommandCentral now supports discovery of Sybase Adaptive Server Enterprise
(ASE) 15.
Added support for the correlation of non-HDS backend array volumes for
HDS Tagma USP and USP-V series arrays
CommandCentral now supports the correlation of the physical disks of HDS Tagma
USP and USP-V series arrays and their backend array volumes (LUNs) when the
backend arrays are from other vendors that are listed in the CommandCentral
Hardware and Software Compatibility List.
Added support for the correlation of backend array volumes for NetApp
V-Series storage systems
CommandCentral now supports the correlation of the physical disks of NetApp
V-Series storage systems and their backend array volumes (LUNs).
Reporting
CommandCentral Storage 5.1 introduces the following reporting features.
Added in-context performance reports for certain objects
When you use the Managing Summary section of the CommandCentral Storage
Console to navigate to an object's Reporting pane, you can now select performance
reports that are scoped for the following objects:

■
Application Access Path Inventory Report: Presents all the combinations of
end-to-end access path inventory (for the logical objects) from application to
the LUN (and the associated array).
■
Fibre Attached Storage Consumption Report: Displays information about fibre
attached storage given to hosts and how that capacity is utilized by the file
systems.
■
■
■
Local vs Remote Replication Report: Depicts how much of the primary (source)
capacity is replicated locally vs replicated remotely.
NetApp Quota Over-Provisioning Report: Provides details about quota allocation
on a NetApp volume and the % over-provisioning.

For more information, see the CommandCentral Storage User’s Guide.
Name of device managers display when viewing list of devices
When you view the list of configured devices in the Console, the Configured Devices
Summary now displays the name of the device manager that manages your devices.
This is helpful when you want to identify the device manager that manages a
specific device. For example, you may want to identify the CIMOM that manages
each of your storage arrays.
For more information, see the CommandCentral Administrator’s Guide.
Ability to set new managed hosts in unmanaged state
In CommandCentral Storage 5.1, you can configure the Management Server to
detect new managed hosts, but not automatically manage those hosts. When this
happens, the Management Server does not collect any data from the managed
host and it does not monitor the managed host. When you are ready for the
Management Server to manage an unmanaged host, you can simply refresh the
managed host in the Console.
For example, you might do this if you have a standard system image policy or if
you need to take advantage of an available installation window.
For more information, see the CommandCentral Administrator’s Guide.
Hotfix deployment mechanism
CommandCentral introduces a new hotfix deployment mechanism that allows
you to push and install hotfixes on remote hosts. The mechanism also allows you

With Symantec’s unmatched breadth and depth, your IT organization can better
align with business objectives and address the issues of cost, complexity and
compliance. Symantec is uniquely positioned to help keep your business up,
running, and growing, no matter what happens.
CommandCentral Storage provides a single, centralized, consistent storage
management console to simplify the complex tasks involved in deploying,
provisioning, managing, and growing a multi-vendor networked storage
environment.
Managing the storage network: introduction
Many organizations—as they adopt e-commerce, supply chain management,
compliance, and other data-intensive applications—find that their data is exploding.
More and more storage is needed to digitize manuals, corporate records, and other
paper-based information, and to hold ever-increasing multimedia content.
If all that volume and complexity weren’t enough of a management challenge,
today’s business environments demand that data be available immediately,
continuously, and from anywhere—to multiple applications and to hundreds,
thousands, or even millions of customers, business partners, and employees.
Storage network technologies
Historically, enterprises have relied heavily on parallel SCSI technology to provide
the performance required for their enterprise data storage needs. More recently,
however, some enterprises are finding that the restrictions imposed by SCSI
architecture are too costly for SCSI to continue as a viable solution.
To overcome these restrictions, many enterprises have turned to a
network-attached storage (NAS) model that enables storage arrays to reside
directly on the main user network, where disk accesses may be made directly
rather than through the server’s network connection. However, this model can
add a significant load to the network, which frequently is already starved for
bandwidth.
16 Getting started with the CommandCentral family
About Veritas CommandCentral Storage
Responding to this problem, some enterprises have implemented storage area
networks (SANs) in which storage is placed on its own dedicated network. This
dedicated network can improve efficiency and reliability by effectively separating
traffic on the storage network from traffic on the main user network.
Storage virtualization
CommandCentral Storage is a valuable asset for enterprises that have implemented
storage virtualization—the process of taking multiple physical storage devices
and combining them into logical (virtual) storage devices that are allocated to
applications and users at will.
Storage virtualization helps ease management by building a layer of abstraction
above the physical storage; however, your administrators still need to penetrate
that layer in order to view and manage the physical storage. CommandCentral
Storage collects detailed information about how physical storage is apportioned
and used, and it provides a graphical user interface for presenting the information
to the administrator.
Although virtualization is not a new concept, CommandCentral Storage now
enables you to take advantage of storage virtualization services over the entire
storage network, across all types of storage hardware and server platforms. You
also gain storage resource management capabilities such as hardware discovery,
visualization, reporting, and a central administration point for your storage
network.
Storage administrator requirements
Because both storage resources and IT personnel vary widely from enterprise to
enterprise, the job of storage administrator is often filled by people with various
skill sets and work backgrounds: mainframe operators, traditional network
administrators, system administrators, and others in the IT industry.
In a utility computing environment, the storage administrator usually works
closely with network administrators and others whose responsibilities range
across the entire IT department. Nevertheless, the storage administrator needs
to know details about how storage is apportioned and used on both the logical
and physical levels. He or she is also responsible for providing overall guidance
on how the storage network is used and on the direction it will take in the future.
Here are some examples of other tasks a storage administrator typically performs:
■
Manage storage resources—for example allocating storage to hosts and the
applications that run on them, and defining logical groups for easier
management
■
Test new vendors’ hardware and integrate it into the storage network
Getting started with the CommandCentral family 17
About Veritas CommandCentral Storage
■
Generate reports about the network’s physical resources and about storage
usage
■
■
■
Troubleshoot network elements
Manage day-to-day performance and resource availability
Develop a data protection strategy and assure that the storage network is
secure
Meeting the needs of storage administrators with
CommandCentral Storage
CommandCentral Storage can maximize the return on your investment in storage
technology. It does so by providing tools designed to help the storage administrator
optimize the operation of your storage network.
Discovery of storage resources
CommandCentral Storage contains in-band and out-of-band discovery methods
for discovering a wide range of network or storage network objects. As a result,
you can discover and monitor physical and virtual fabrics, hosts, groups, storage
devices (such as arrays and NetApp unified storage devices), and applications.
Versatile displays of information about storage resources
The CommandCentral Storage Console provides a rich, versatile set of graphical
and textual displays with which you can visualize physical resources—such as
hosts and arrays—and logical resources—such as virtual fabrics—as well as the
connections and interrelationships between them. Displays also include storage
usage reports and projected storage consumption trends.
Policies for managing resources
Using the CommandCentral Storage Alert Manager, you can define and manage
policies that are associated with objects in your storage network. A policy consists
of a condition to monitor, such as heavy traffic on a specific switch port, and a
set of actions to take when that condition is met. In addition to the policies you
define, an extensive set of default policies is included with the CommandCentral
Storage product.
Data collection
CommandCentral Storage includes a versatile set of collectors that gather
information about network resources for evaluation by the Alert Manager.
CommandCentral Storage collects information about capacity, environmental
conditions (such as temperature), performance, traffic, errors, and object
availability.

About Veritas CommandCentral Storage Change Manager
Storage provisioning
Using tools provided in CommandCentral Storage, a storage administrator can
allocate storage resources to specific hosts and applications and control access
to storage resources. You can also create LUNs from unconfigured storage. Another
feature allows provisioning jobs to be scheduled for times when the network is
less busy.
Through the use of storage accounts, a senior administrator can establish
provisioning guidelines, or policies, that regulate the actions of lower-level
administrators.
Graphical reports about network resources, performance, and events
CommandCentral Storage includes an extensive set of graphical reports with
which you can display collected data about resources, performance, history, and
changes on your storage network. You can also create custom reports tailored to
your own needs. By enabling you to monitor things like trends in storage usage,
these reports can help you use your storage assets more efficiently.

sources database schema. With Enterprise Reporter 5.0 MP1, you no longer need
to run these scripts. Instead, when you add a new data source, Enterprise Reporter
automatically prepares the data source before adding it.
Data rollup view enhancements
Enterprise Reporter 5.0 MP1 includes enhanced Data Rollup Configuration views
that improve usability and efficiency. For example, if you enter the fully qualified
host name or IP address of the database server host when you add a data source,
Enterprise Reporter fills in related data source information. Additionally, fields
that were not integral to the process of setting up a data source were removed
from these views.
Storage tier rule builder enhancements
In addition to the Advanced Rule Builder, Enterprise Reporter 5.0 MP1 now
includes a Basic Rule Builder. Both of these tools help you create rules that govern
the assignment of storage to specific storage tiers, but the Basic Rule Builder
lessens the complexity of creating and modifying rules. For example, in the Basic
Rule Builder, you no longer have to type complex SQL statements. The Advanced
Rule Builder remains in Enterprise Reporter.
For more information about these tools and storage tier rules, see the
CommandCentral Enterprise Reporter Administrator’s Guide.
Reporting enhancements
Enterprise Reporter includes the following reporting enhancements.
Sample reports
Enterprise Reporter now includes the following sample reports that are related
to NetApp unified storage devices:

Dashboard customization with selected reports
By default, the Dashboard shows report categories and their descriptions. With
Enterprise Reporter 5.0 MP1, you can customize the Dashboard to show any report,
including one that you created. Enterprise Reporter provides a new "Set This as
Home Report" option that enables you to display a selected report on the
Dashboard.
For more information about the Dashboard, see the CommandCentral Enterprise
Reporter User's Guide.
New package and metrics
Enterprise Reporter 5.0 MP1 now includes the following additions, which expand
the storage asset data that you can report on:
■
The new Storage Analysis package includes the metrics from the 5.0 Array
Analysis package as well as additional metrics. We recommend that you use
this new package instead of the Array Analysis package that shipped with 5.0.
The Storage Analysis package includes the following metrics:
■
Storage capacity metrics, which are equivalent to the Array Analysis
package metrics.
■
SAN and DAS storage metrics, which are equivalent to the allocated storage
metrics in the Array Analysis package (located in Array Analysis >
Configured Capacity Metrics > Allocated Storage Metrics).
■
NAS Storage metrics, which include NAS volume capacity data and NAS
inventory data for volumes, qtrees, volumes, shares, folders, files, and
users.
■
■
The new NetApp package includes NetApp data about unified storage devices,
such as Multistore Virtual Systems, volumes, qtrees, and shares.
A new metric, Drive Type, was added to the following packages:
■
■
Host Storage Allocation package
Tiered Storage Allocation package
The Drive Type metric indicates the physical disk drive that is used for creation
of the LUN. Values include Fibre Channel, ATA, and Unknown.

What you can do with CommandCentral Enterprise Reporter
Enterprise Reporter includes a global view of storage with the ability to roll up
information from multiple data centers into a single comprehensive
view—organized by lines of business, geography, application, or other customized
views. It can help compare trends across continents, find the application
consuming the most storage in a particular data center, or locate the business
unit consuming more than its fair share of storage.
Storage administrators can use Enterprise Reporter along with CommandCentral
Storage. While CommandCentral Storage provides an operational view of storage
data primarily for storage administrators, Enterprise Reporter summarizes this
data across data centers and integrates business information, allowing for a global
view for CIOs, directors, and business unit leaders.
For example, business leaders use Enterprise Reporter to identify storage trends
(such as an alarming regional growth rate of tier 1 storage). Then, administrators
use CommandCentral Storage to help ensure that the appropriate storage service
is being delivered to the business.
26 Getting started with the CommandCentral family
About Veritas CommandCentral Enterprise Reporter
Business executives and storage administrators can use Enterprise Reporter to
do the following:
■
■
■
Develop highly customizable business views of data from multiple data sources.
For example, administrators can discover global storage usage trends and drill
down to identify high consumers across geographic or business units.
Create storage tiers that match business needs and associate costs with each
tier. Administrators can then identify where storage is allocated appropriately
to costly tiers.
Create ad hoc reports quickly by inserting data fields (such as host attributes,
array attributes, allocated capacity, and claimed capacity) into a report table.
Add selectable and customizable filters to narrow the focus or display data
visually using charts for quick interpretation. To focus on specific business
units, users can drag customized business view options into the report, easily
grouping data into business units.
■
Create advanced reports incorporating more advanced layout options, such
as maps, images, and HTML. Also, add multiple queries to reports or insert
prompts that request report users to select the report focus that they want
prior to running the report.
■
■
■
Automate report generation with a specified schedule and set automated
distribution through email.
Develop a personalized dashboard in Cognos Connection containing customized
reports that display answers you need quickly.
Select a sample report or report you created as the default report for the
Enterprise Reporter Dashboard.
How CommandCentral Enterprise Reporter works
Multiple data centers, each with one or more CommandCentral Storage
Management Servers, send data to Kettle, which performs extract, transform, and
load (ETL) processes. Kettle aggregates the data and prepares it for use by the
Oracle database. Kettle then loads the data into the Oracle database.
The Oracle database, an enterprise-scalable database, stores the data and passes
it to Cognos. Cognos enables users to select data, filters, and business views to
develop customized reports. Administrators and analysts use Cognos Connection,
Query Studio, and Report Studio to create personalized dashboards and design
reports.
Enterprise Reporter enables users to see the aggregated data in customizable
reports via its Console. Administrators also use the Console to configure data
rollup, storage tiers, business views, and user accounts.

delete
See CommandCentral Storage database.
In CommandCentral Storage, an operation that removes discovery information
about one or more objects from the CommandCentral Storage database. The states
of the objects themselves—for example, the existence of a LUN on an array or the
configuration of a switch—are not affected by the delete operation. Optionally,
deleted information can be restored to the database by a rediscover operation.
Contrast with destroy. See also rediscover.
destroy
In CommandCentral Storage, an operation that modifies the configuration of one
or more devices in the SAN. Examples are destroying zones and destroying port
bundles, both of which modify the configuration of one or more switches. Unlike

Storage database by a rediscover operation. Contrast with delete.
device
A collective term for disks, tapes, disk arrays, tape arrays, and any other objects
that store data. Also storage device.
device handle
The name the operating system uses to identify a storage resource (known as an
addressable unit or LUN), and the correct means (driver, system call) to access it.
Also OS handle.
discovery
The process of finding objects on the storage network and adding information
about them to a database. In CommandCentral Storage, most discovery is done
by the Hardware Abstraction Layer, which stores information about storage
resources in the CommandCentral Storage database. Discovery of storage arrays
is performed by the Veritas Array Integration Layer (VAIL). See also explorer and
extended discovery.

CommandCentral Glossary 41
GBIC
Gigabit interface converter. A widely used transceiver module for Fibre Channel.
A GBIC is modular and hot-swappable and can be either copper or optical.
generic device
A disk or tape device. When generic storage devices are visible to a host running
the Hardware Abstraction Layer (HAL), the CommandCentral Storage Console
displays the correct object type.
generic group
group
A user-defined collection of switches, hosts, and storage devices. The Group Builder
tool is used to create and modify generic groups. See also group, object dependency
group.
A class or collection of storage objects. Groups are useful for a number of different
purposes, for example scoping reports and views to encompass a set of objects
with similar attributes. CommandCentral Storage supports two types of groups:
generic groups, which are defined by users, and object dependency groups, which
are defined automatically to track volumes and file systems having dependencies
on specific applications.
GS explorer
An explorer that uses the Fibre Channel Common Transport (CT) protocol to
discover switches in-band over Fibre Channel, obtain switch characteristics, and
explore port connectivity. Prior to CommandCentral Storage version 5.x, the GS
explorer was known as the MGEX explorer.
guest operating system An operating system that is installed on a virtual machine. See also managed
virtual host.
hard zoning
A fabric zoning method in which a Fibre Channel switch actively blocks access to
zone members from any objects outside the zone. Because the active blocking
takes place at the level of ports on the switch, hard zoning is also referred to as
switch port zoning. In hard zoning, each switch uses a routing table to determine
whether data is allowed to flow across a connection. See also soft zoning.
HAL (hardware
A component that performs device discovery and management for storage
applications and devices. HAL maintains a real-time topology of the storage
network and interacts directly with switches and storage arrays to control access
to storage resources. HAL extends the functionality offered in previous releases

Channel network.
HBA port group
A group of HBA ports for which a single LUN masking operation applies to each
port in the group. In CommandCentral Storage, you can create HBA port groups
using the Console. For EMC EVA and CLARiiON arrays, the term host may be used
to refer to an HBA port group. For NetApp devices, the term initiator group is
used. See also LUN masking.
host bus adapter
See HBA.
42 CommandCentral Glossary
host storage domain
hub
See array virtual port.
A common connection point for devices in the storage network. The hub may be
unmanaged, IP-managed, or FC-managed. An unmanaged hub is passive in the
sense that it serves simply as a conduit for data, moving the data from one storage

LUN (logical unit
number)
A unique and discrete addressable unit or logical volume that may reside inside
one or more simple or array storage devices. LUNs are exposed to the outside
world through an addressing scheme presented to the host as SCSI LUN numbers.
Each LUN has a unique device handle and represents a logical volume.
LUN binding
LUN masking
The creation of access paths between an addressable unit (AddrUnit) within a disk
array and a port on the array. AddrUnits are storage volumes built out of the
physical disks within the array. Array ports are connected to the SAN fabric and
function as SCSI targets behind which the AddrUnits bound to those ports are
visible.
The practice of enabling access to a particular addressable unit (AddrUnit) for a
host on the storage network. This is done by creating an access control list
CommandCentral Glossary 43
associated with the LUN (the access path) between that AddrUnit and an array
port to which it is bound. The access control list for a LUN contains the World
Wide Name of each HBA port that is allowed to access that LUN within the array.
LUN Query Tool
A CommandCentral Storage tool that helps you find LUNs on your storage network
that match one or more properties, such as device vendor, storage type, capacity,
configuration, cost, and location. The LUN Query Tool can further refine the
search for LUNs based on the groups to which they are assigned or based on their
accessibility from specified SAN-attached hosts.
