Preparing An Hp Continuous Access Eva Environment For Upgrading - HP 6100 Software Manual

3. Verify that no changes to the storage system configuration are in progress. For example, you
should not be in the process of creating a virtual disk. Configuration changes should not be made
within 48 hours before beginning the upgrade. Proactive event notification can be used to alert
you if a critical event occurs during the 48 hours before the upgrade.
NOTE:
The leveling process does not impact the upgrade. If leveling is in progress, the upgrade
can be performed. The leveling will be suspended during the upgrade and resumed
when the upgrade is complete.
Ensure you suspend any processes or applications that may change the storage system
configuration, such as backups and snapshot creation or deletion. Stop any HP Storage
System Scripting Utility scripts that are scheduled to run automatically.
Preparing an HP Continuous Access EVA environment for
upgrading
IMPORTANT:
Upgrades to an HP Continuous Access EVA configuration are performed from the management server
(running HP Command View EVA) that is local to the array.
Estimated time to complete: Varies depending on replication configuration
When to perform: As close as possible to the upgrade
When upgrading an EVA in an HP Continuous Access EVA environment, the following requirements
must be met:
• Before you upgrade any storage system in an HP Continuous Access EVA relationship, ensure that
all storage systems in the storage network are running the same version of controller software.
This will ensure that when you upgrade one storage system, the storage network will have only
two versions of controller software. You cannot have more than two versions in an HP Continuous
Access EVA environment.
• During the time that the HP Continuous Access EVA storage systems are running different controller
software versions, you cannot make any configuration changes to your storage systems.
• You must perform the necessary upgrades to the storage systems in the HP Continuous Access
EVA relationship within 60 days (1440 hours) to make all controller software versions the same.
• Check the HP firmware policy for additional upgrade information:
