On deleting a tape device, the ref counts for the device were found to be incorrect. These incorrect ref counts prevented the device from being deleted properly. 2. The DRD_KGS_WAIT_TRANS_DONE flag was left set after the transaction was done. This is a minor problem that could have been caused due to the problem with the ref counts. 3. A drd ref count is left on when a cluster member loses access to a tape and then regains it. This could prevent a customer from being able to delete the tape when the cluster regains from the transition. 4. On certain types of media errors, a tape device could be left in an unusable state. The device will always return "busy" even though no transaction is in progress on that device. 5. When an upgrade is done to TCR 5.1B-2/PK4, the cluster could lose access to backplain RAID devices (e.g., KZPAC, KZPCC, etc). 6. A kernel memory fault panic experienced when no local devt is available for a device that is locally accessible. 7. A problem experienced when all paths to a disk are lost and a persistent reservation (i.e., barrier) is in progress. 8. A deadlock situation in open/close when all paths to a disk are lost. 9. A deadlock problem experienced when local connectivity is regained when an open is in progress.
