Sun Storage 7000 Unified Storage System: Messages like "stmf_ic_scsi_data_msg_unmarshal: nvlist lookup of icsd_task_msgid and friends failed" when upgrading appliance software on a cluster (Doc ID 1478668.1)

Symptoms

When upgrading a cluster that presents Fibre Channel LUNs to clients, after the first head has been upgraded successfully, error messages like:

may appear in the system log.

It may also be noticed at this time that the STANDBY path(s) from the clients to the LUNs, that are usually presented by the "standby" cluster peer (i.e. the cluster head that is the partner of the head that owns the pool that contains the LUNs), are now offline.

This can make it seem as though the error messages are related to the loss of the standby paths, and that proceeding with the upgrade may be dangerous.

Changes

The cluster appliance software is being upgraded.

One head has been successfully upgraded, has rebooted and rejoined cluster but now has a different appliance software version to it's peer.
