Hi, I am having a very annoying problem with a recently acquired Spectra 2K library, I was hoping that someone on the list could confirm this.
My configuration: TSM 5.3.0.0 on Red Hat Enterprise Linux 3.0 Spectra 2K (Treefrog) library, SCSI attached Two AIT-4 (SDX-900V) drives The problem: When dismounting a tape after a read or write operation, the tape is ejected from the drive but the tape picker does not move the tape back to its slot in the library. Because TSM 5.3 now uses the native Linux SCSI driver (sg) instead of loading its own modules, I was able to trace that TSM keeps a file descriptor open on the tape device while at the same time issuing a "move medium" command to the library. The file descriptor is kept open as long as the volume is in the "dismounting" state. Eventually the "move medium" command times out, and TSM logs an I/O error on the changer. After doing several dismount retries, TSM abandons the operation and removes the file descriptor, and at that precise moment the picker wakes up and moves the tape back to the slot. Of course, after that TSM has lost track of the tape and an "audit library" is required... My conclusion is that the library tries to inquire on the drive before picking up the ejected tape, but the drive is blocked by the open file descriptor. AFAIK, it is TSM's normal behaviour to lock the drives until the completion of the dismount operation (I have done tests on AIX, not with the same library though). So the problem is that the library is not obeying to the "move medium" command when it should. I wrote to Spectra Logic about this, they have not gotten back to me yet. Anyway, if anyone has worked with this library or had any similar experiences, your insight is much appreciated :-) Many thanks, Dmitri --------------------------------------------------------------------------- This message (including any attachments) is confidential and may be privileged.
