8100 Updating Product Software Guide (XCS 6.250) (5697-1716, February 2012)

have only two versions of controller software. You cannot have more than two versions in an

HP P6000 Continuous Access environment.

• While the HP P6000 Continuous Access storage systems are running different controller

software versions, you cannot make any configuration changes to your storage systems (for

example, do not add or delete DR groups or members of DR groups).

• You must perform the upgrades to the storage systems in the HP P6000 Continuous Access

relationship within 60 days (1,440 hours) so that all arrays are running the same controller

software versions the same. After upgrading the first storage system, wait at least three minutes

before upgrading the second storage system. Ensure that the previously described requirements

are met on the second storage system.

• If you need to upgrade both XCS and VCS, complete the upgrade of one before upgrading

the other. For example, upgrade all arrays running VCS before upgrading arrays running

XCS.

• Ensure that no DR group is logging, merging, or copying. For all DR groups, ensure that the

failsafe state is Unlocked and the Failsafe on unavailable member mode is Disabled.

• Ensure the connection between the storage systems is not compromised or failed.

2. Check the Connection State in the Data Replication Folder Properties window.

• All EVA storage systems must be running normally with fully functional controller pairs.

Upgrading disk drive firmware in an HP P6000 Continuous Access environment

When upgrading disk drive firmware in an HP P6000 Continuous Access environment, the following

requirements must be met:

• Perform the disk drive firmware upgrade using the local management server (the server running

HP P6000 Command View that is local to the EVA being upgraded).

• Do not perform HP P6000 Continuous Access copy/merge activities across sites, site failovers,

cloning, or grouping/ungrouping of disks during an upgrade.

• Do not add or remove members from DR groups.

• For all DR groups, ensure that the failsafe state is Unlocked and the Failsafe on unavailable

member mode is Disabled.

• Suspend replication and disable the intersite link or modify zoning to isolate the source array

from the destination array.

• Upgrade the disk drive firmware on the destination array.

• Re-establish intersite link communication between the arrays and resume replication, allowing

the DR group merges to complete.

• Perform site failover.

• Suspend replication and disable the intersite link or modify zoning to isolate the source array

from the destination array.

• Upgrade the disk drive firmware on the new destination array (before site failover, this was

the source array).

• Re-establish intersite link communication between the arrays and resume replication, allowing

the DR group merges to complete.

• Perform site failback.
