TSM RMAN Backup Implementation & dircetory permissions issue.

TSM Implementation

We have started implementing RMAN Backup with Tivoli Storage Manager.
Things were set, TSM Client installation was done, TDPO file also was created and we have tried to run a test backup but backup fails with below error.

RMAN-03009: failure of allocate command on c1 channel at 01/23/2011
11:12:42
ORA-19554: error allocating device, device type: SBT_TAPE, device name:
ORA-27000: skgfqsbi: failed to initialize storage subsystem (SBT) layer
Linux-x86_64 Error: 106: Transport endpoint is already connected
Additional information: 7011
ORA-19511: Error received from media manager layer, error text:
SBT error = 7011, errno = 106, sbtopen: system error


Solution :

Wile trying to run backup TSM Client tries to update to file tdpoerror.log for which the “ORACLE” user need to have read Wright access to below location.

/usr/tivoli/tms/client/oracle/bin64/

Or

/opt/Tivoli/tms/client/oracle/bin64/

After oracle user have read write access to oracle for TSM client installation path.
