Hi All I have a client with a new installation TSM 5.3.3 on Windows 2003 on IBM x346 and 3583 with 3x LTO3 Drives.
I initially had some issues with the tape drives because one of them had been connected to the internal SCSI bus and that not only was not supported, it caused multiple tape errors. So, I corrected that - the library manager and one tape drive are on one adaptec SCSI adapter and the other two drives are on another adapter - and we're running through doing initial backups of about 7TB of client data, bit by bit each night. But the tapes seem very unreliable - I had two with errors night before last and one last night. These also make the housekeeping run very slowly so I'm not getting it all done. Last night's tape was first used yesterday afternoon on drive0, then again at 16:00 on drive2 then overnight again on drive0. Its now showing errors being read on drive0, so its a bit hard to isolate the problem. The tapes are all new Imations - I could not get IBM branded ones in a timely manner. Has anyone had problems with new LTO3s? Any suggestions as to what to do next are welcome. Steven Harris AIX and TSM Administrator
