HP StorageWorks Enterprise Virtual Array Updating Product Software Guide (XCS 09534000) (5697-0754, October 2010)

Before beginning the upgrade, it is recommended that you perform a full verified backup of all storage
system data. Although not required, it is always good practice to back up your data before performing
major operations such as software upgrades. The backup should be scheduled as close to the upgrade
process as possible.
For more information about establishing and implementing good backup procedures for the EVA,
contact your HP sales representative.
TIP:
If using server-based management, HP recommends that you also back up the management server
before you begin the upgrade.
Upgrading HP Command View EVA
HP Command View EVA can be implemented in two ways:
• Server-based management — HP Command View EVA is installed on a management server con-
nected to the EVA, providing management of multiple HP EVA storage systems. All components
of the software suite (HP Command View EVA, HP Command View EVAPerf, HP Storage System
Scripting Utility, SMI-S EVA) are installed. Server-based management applies to all EVA models.
• Array-based management — Beginning with HP Command View EVA 8.1, the EVA4400 is
shipped with HP Command View EVA pre-installed on the management module within the controller
enclosure. Only one component of the software suite (HP Command View EVA) is installed. Array-
based management applies only to the EVA4400.
Follow the procedures in this section to upgrade HP Command View EVA on the management server.
If you have an EVA4400 and are using array-based management, see “Upgrading the management
module” on page 39 for upgrade instructions.
NOTE:
Before starting the upgrade, check the release notes for the version to which you are upgrading for
any details on the upgrade process.
Estimated time to complete: 15–20 minutes or longer, depending on your configuration.
When to perform: Any time before the upgrade
TIP:
To help ensure fast recovery from the upgrade, it may be useful to remove a disk from the management
server.
For supported upgrade paths, see Table 2.1, HP Command View EVA upgrade support, in the HP
StorageWorks Enterprise Virtual Array Compatibility Reference.
For more information on HP Command View EVA, including the HP StorageWorks Command View
EVA Installation Guide and the release notes, download documentation from the website listed in
