Error description
The Tivoli Storage Manager server can crash during Netezza client backups. NOTE: This issue could apply to other clients that use the Tivoli Storage Manager API, but has only been witnessed with Netezza clients to date. The root cause of this issue is that the client is not adhering to proper API protocol. Instead of returning a protocol violation back to the client, the server unexpectedly crashes. This APAR will prevent the crash and make the server return a protocol violation back to the offending client. This will likely still result in a client backup failure. To allow for a client backup success, the client must also be changed to avoid the protocol violation. Customer/L2 Diagnostics: A failing callstack similar to the following can be extracted from the resulting core dump: HashFindCopyGroup() pmGetBackupVersions() imDeactivateBackup() imUpdateInventory() imPrepareTxn() CollectVotes() tmEndX() EndVbTxn() SmNodeSession() HandleNodeSession() DoNodeGeneral() smExecuteSession() psSessionThread() StartThread() start_thread() clone() Initial Impact: High Tivoli Storage Manager Versions Affected: All Tivoli Storage Manager server users. Additional Keywords: TSM ABORT ABEND CRASH OUTAGE NETEZZA NETEZA CLIENT API PROTOCOL VIOLATION HASHFINDCOPYGROUP DEACTIVATE BACKUP
Local fix
Disable the offending client backups to prevent the crash.
