Hi, I am having some weird problems with TSM, RMAN and TDP for Oracle. Everything is on Windows 2000, above the 5.2 level, server and clients (2 Oracle servers running on 2 MSCS clusters) are at 5.2.2. We are using a 3584 with 6 3580-LTO2 drives connected on the SAN with a McData 4500 switch.
We have been doing LAN-Free backup/restore (incremental, selective, restore) using multiple drives from these two Oracle servers directly to tape without a problem, but with RMAN it is a totally different story. We have been trying to do RMAN Level 0, 1 and 2 backups using 4 channels directly to tape. Last week, we could not get any backup to complete. In the activity log, two drives would show repeated ANR8779E errors: Unable to open drive mt5.0.0.6 (and mt4.0.0.6), error number=170 or error number=5. This would cause a ANE4994S error: DP Oracle Win32 ANU0599 TDP for Oracle: (1136): => () ANS1301E (RC1) Server detected system error So I put the two paths to those two drives offline. I was able to get ONE successful backup using 4 channels. Then, another error started showing up: ANR8311E I/O error occurred while accessing drive DRIVE4 (mt0.0.0.6) for WRITE operation, errno = 1117. This would cause the RMAN to fail about 60% through a 250GB backup and the tape in the drive had its access set to readonly. So far this has happened to all four "good drives" and on 7 different tapes on two different nights. And last night, the RMAN simply stopped working all together. It gave the following error: RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03007: retryable error occurred during execution of command: allocate RMAN-07004: unhandled exception during command execution on channel c1 RMAN-10035: exception raised in RPC: ORA-19554: error allocating device, device type: SBT_TAPE, device name: ORA-19557: device error, device type: SBT_TAPE, device name: ORA-27000: skgfqsbi: failed to initialize storage subsystem (SBT) layer ORA-19511: SBT error = 7011, errno = 2534, sbtopen: system error RMAN-10031: ORA-19624 occurred during call to DBMS_BACKUP_RESTORE.DEVICEALLOCATE Recovery Manager complete. The TSM server did not get a connection from that session. Anybody out there have RMAN backing up directly to tape and have it working?
