HP StorageWorks 3000/5000 Enterprise Virtual Array updating product software guide (VCS 3.110) (5697-8108, March 2009)

3 Upgrading the Enterprise Virtual Array
The following steps guide you through the process of upgrading the system software. Ensure that you
follow them carefully and in the specified order. Table 5 on page 37 provides a checklist so you can
track your progress as you perform the upgrade. Make sure you have all the items indicated before
beginning the upgrade.
Upgrading remotely versus locally
You can perform the upgrade from a local server or from a remote server. Some advantages to
performing the upgrade locally include:
• Enables you to view the various status indicators on the storage system hardware to ensure
everything is working properly.
• Provides access to the controller operator control panel (OCP) to clear storage system passwords
and to monitor messages.
• Reduces the amount of time involved during file transfers. The shorter distance over the network
the code files must travel, the faster the transfer will occur.
Solving upgrade problems
If you experience any problems when performing the VCS upgrade procedure, see
“Troubleshooting” on page 57 for assistance. If you are still unable to resolve the problem, contact
your HP-authorized service representative for assistance.
