After-upgrade maintenance checks
ACS V8.7-2 potentially allows for silent metadata inconsistencies to develop if a
disk drive was spared into a RAIDset (either manually or automatically). With
ACS V8.8-1, at the time the controller is first upgraded, the firmware provides
metadata inconsistency corrections within the controller memory. However,
corrected information is not written to the disk devices during the upgrade
process. Although the controller continues to function normally, unit failovers
work correctly, and there is no impact to you, HP recommends that you take the
steps necessary to correct the inconsistency that exists on the metadata portion of
the container.
This section provides specific subsystem checks that you must complete after you
upgrade to ACS V8.8-1. Specific after-upgrade topics include:
■ Handling RAIDset containers with at least one unit above the container
(recommended offline method)
■ Handling RAIDset containers without a unit above the container
■ Manually manipulating disk devices needing repair (alternative procedure)
■ Handling concatenated storagesets with RAIDset containers needing repair
■ Handling target site remote copy sets made of RAIDsets that need repair
■ Handling initiator site remote copy sets made of RAIDsets that need repair
■ Handling failures during the add of a unit above a RAIDset container
Note: Perform the following check only if the ACS version before upgrading the
subsystem to ACS V8.8-1 was ACS V8.7-2 or a later patch. Do not perform the
following checks if you were running only ACS V8.6-x, V8.7-0 or V8.7-1 previous to
upgrading to ACS V8.8-1.
Note: If you decide to physically remove the members of a RAIDset and place them
into another subsystem running ACS V8.7-x or V8.6, and that RAIDset currently
shows a status of Maintenance Recommended, it is essential that you perform the
REINITIALIZE
container-name CLI command before removing devices in the
container from the ACS V8.8-1 subsystem.
After completing the ACS upgrade, execute the following command on each
controller if you upgraded from ACS V8.7-2 or later:
