When performing an upgrade to SAN/iQ v8.5, I noticed that the management group version wasn’t being updated to 8.5 and was still at 8.0 even after upgrading all nodes in the management group. I also noticed that the Network RAID 5 feature wasn’t showing up in the list for the volumes (either on new volumes or editing existing volumes).
The reason behind this was because the management group was in a remote IP copy relationship with another “DR” management group, which was not upgraded to 8.5 yet. Once I upgraded the nodes on the DR management group, everything upgraded like it should and the new Network RAID options were available.
Note: This behaviour is shown in the upgrade guide too, page 12:
• When upgrading from version 7.x to release 8.5, the management group version will not move
to release 8.5 until all storage nodes in the management group (and in the remote management
group if a Remote Copy relationship exists) are upgraded to release 8.5 SAN/iQ.
• When upgrading from version 7.x to release 8.5, the upgrade process validates the hardware
identity of all of the storage nodes in the management group. If this validation fails for any reason,
the management group version will not be upgraded to 8.5. For example, if a management group
has a mix of platforms, some of which are unsupported by a software release; then only the supported
platforms get upgraded successfully, the management group version will not be upgraded
if the unsupported platforms remain in that management group.
