Hello:
Before I begin, here are the hardware specs of our small TSM environment:
TSM SERVER VERSION: 5.4.2.0
TSM SERVER OS VERSION: Windows Server 2003 R2 Standard Edition
TSM SERVER TYPE: IBM System x3650 (MEMORY: 4096 MB; CPU: Quad 2.33 GHz Intel
Xeon)
PHYSICAL TAPE LIBRARY: IBM 3576 w/ four tape drives (SCSI attached to TSM
server)
VIRTUAL TAPE LIBRARY: DL210 (fiber attached to TSM server)
SCSI ADAPTER: Adaptec SCSI Card 29320LPE - Ultra320 SCSI (driver version
7.0.0.6)
I'm not sure what else needs to be mentioned from a hardware configuration
perspective. But, today we had someone replace some bad memory in our TSM
server. When the system was back up and TSM was up, our standard operating
procedure is to test both virtual and physical tape mounts by running simple
"MOVE DATA" commands. When we tested the virtual tape library, no problems at
all, but when we tested the physical tape library, we received and continue to
receive the following error for all four tape drives:
03/20/2013 18:18:20 ANR8939E The adapter for tape drive KSFS0203-DRIVE03
(\\.\Tape67<file:///\\.\Tape67>) cannot handle the
block size needed to use
the volume. (SESSION: 341, PROCESS: 3)
HOWEVER, when we run an incremental TSM database backup, which uses a new
scratch tape, it works without issue. Absolutely NOTHING has changed from a
software/firmware perspective in our TSM environment. In troubleshooting the
problem, we completely removed the physical tape library and tape drives from
an OS and TSM perspective, reconfigured them, but still continue to receive the
errors.
Has anyone run into this issue before? Does anyone have any suggestions?
Thanks...
Charles Welton
