HP StorageWorks P4000 User Manual page 48

Before upgrading the storage systems in a management group or available storage systems, verify
the following:
• For all storage systems:
• You are using version 9.0 or later of the CMC.
• All storage systems are in a good state, with no critical events.
• If you are using the HP DSM for MPIO or the CLI, upgrade them first.
• If you are using VSS, be prepared to upgrade it during the SAN/iQ upgrade process.
• For storage systems in a management group:
• You are logged in to the management groups you want to upgrade.
• At least two storage systems are running managers, so you will not lose quorum.
• If you want to maintain availability to volumes during the upgrade, your management group
must be configured with Network RAID-10 (2–Way Mirror) or higher.
• All virtual managers in the management group are stopped.
NOTE:
During the upgrade procedure, you may receive a warning that the CPU Utilization value exceeds
90, for example: CPU Utilization = 97.8843. Value exceeds 90. This is an expected
occurrence during an upgrade. No action is needed.
