HP StorageWorks Enterprise Virtual Array 3000/5000 updating product software guide (VCS 3.110) (5697-7959, February 2009)

• Before upgrading your storage system to VCS 3.110, all source and destination DR groups must be
in synchronous mode. Check each DR group to verify this setting, before proceeding with the
firmware upgrade p rocess.
• 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 env ironment.
• 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 H P Continuous Access
EVA relationship within one week (168 hours) to make all controller software versions the same.
CAUTION:
In an HP Continuous Access EVA environment, do not begin the upgrade until the following conditions
are met. If you attempt to upgrade the controllers before the following conditions are met, controller
operation will fail.
• Ensure that no DR group is logging, merging, or copying. Furthermore, none of the DR groups can
be in a failsafe locked state.
