Error description
In the event that a multi-threaded no-query restore operation should fail due to a communication failure, restarting the restore operation may result in a single-threaded restore. This can significantly affect the performance of the restore operation. Tivoli Storage Manager Versions Affected: All platforms/versions affected Customer/L2 Diagnostics: The activity log excerpt will initially show multiple restore sessions started for the client, with each individual session independently restoring data: ANR0406I Session 89804 started for node TSMCLIENT (WinNT). ANR1183I Initial determination of removable volumes required for a restore request from session 89804 is complete. Additional volumes may still be required. ANR0406I Session 93173 started for node TSMCLIENT (WinNT). ANR0406I Session 93176 started for node TSMCLIENT (WinNT). ANR0406I Session 93177 started for node TSMCLIENT (WinNT). ANR0406I Session 93179 started for node TSMCLIENT (WinNT). ANR0510I Session 93176 opened input volume 200187L5. ANR0510I Session 93177 opened input volume 200137L5. ANR0510I Session 93179 opened input volume 200404L5. ANR0510I Session 93173 opened input volume 200173L5. ANR0510I Session 89804 opened input volume 200290L5. A communication failure than causes the initial multi-threaded restore operation to fail: ANR0480W Session 93176 for node TSMCLIENT (WinNT) terminated - connection with client severed. ANR0403I Session 93179 ended for node TSMCLIENT (WinNT). ANR0403I Session 93173 ended for node TSMCLIENT (WinNT). ANR0403I Session 93177 ended for node TSMCLIENT (WinNT). ANR0403I Session 89804 ended for node TSMCLIENT (WinNT). Upon restarting the restore operation, the activity log will show the client attempting to start multiple restore sessions on the server, however, all but one of these sessions will end immediately: ANR0406I Session 108021 started for node TSMCLIENT (WinNT). ANR1183I Initial determination of removable volumes required for a restore request from session 108021 is complete. Additional volumes may still be required. ANR0406I Session 108028 started for node TSMCLIENT (WinNT). ANR0406I Session 108029 started for node TSMCLIENT (WinNT). ANR0406I Session 108030 started for node TSMCLIENT (WinNT). ANR0403I Session 108030 ended for node TSMCLIENT (WinNT). ANR0403I Session 108028 ended for node TSMCLIENT (WinNT). ANR0403I Session 108029 ended for node TSMCLIENT (WinNT). The restarted restore operation run to completion, but will be single-threaded. Initial Impact: Medium Additional Keywords: nqr restore restart restarted restartable
