Cause

        
Appliances running PowerStoreOS version 3.6 or earlier version may have SCSI3 reservation with invalid or mismatch SCSI registration

  
During NDU to version 4.0.x of such appliances, NDU may fail if the owner_idx has no corresponding SCSI reg object. However, if the owner_idx is reused (even if it is for a different volume), NDU to 4.0.x will succeed. In such scenario, when system runs on version 4.0.x code, the invalid or mismatch SCSI registration may cause a System Manager (SYM) rolling panic condition.
