Cause
For ALUA mode array, DMP uses MODE_SENSE command to find implicit/explicit failover mode and this appears to be triggering these messages. The EMC Clariion arrays do not support the MODE_SENSE command.
Resolution
These messages are considered harmless and do not have any functional impact.
Applies To
VxVM 6.1.1 / 6.2
