IMPORTANT:
It is crucial that you check application timeouts to verify that they are equal to or longer than the
timeout thresholds for the upgrade.
Although an application may survive the online controller software upgrade successfully, there may
be an impact on performance. To minimize the performance impact on users, the online upgrade
should be performed during a period of low user activity.
Back up all storage system data
Estimated time to complete: Varies
When to perform: As close as possible to the upgrade
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.
