Anyone running a 3583 with LTO-2 drives on Win2K? Something that might be pertinent to the I/O errors that this thread originally discussed is the SCSI adapter being used - if not fiber connected. We implemented a 3583 with LTO-2 drives recently and were experiencing terrible performance - including intermittent I/O errors and tapes going reado or unavail - the performance was OK with disk to tape migration but tape to tape copy was extremely slow. 32Gig of data would take in excess of 16 hours to copy.
After upgrading the TSM server code to 5.2 and no difference in performance, we upgraded firmware. With everything updated to the latest and greatest - we still did not see any improvement. The only other variable was the SCSI card and cable - the card being what IBM supports in their X-Series servers - an Adaptec 29160. We'll - after searching the knowledge Base on the Adaptec site we got a hit on performance problems with CD-Writers and some backup tape units - not very specific - but it was worth a shot. Well, after downloading the updated Adaptec driver - Dated Nov 2002, the performance increased dramatically - we now do Tape to Tape copy at the real speed the LTO-2 is rated - even better. We now do the same 16Gig file in about 6 minutes compared to 16hours. So far we have not seen ANY I/O errors again. So - don't just blame the 3583/3580 hardware and media - look at the rest of the server as well. If you have this type of card - do yourself a favour and get the updated driver.
