alanrh Posted November 28, 2005 Report Share Posted November 28, 2005 We are using Retrospect Server 6.1 on a Mac OS-X 13.3.9 G4 system. Our storage hardware is an Overland SDLT Loader Xpress. The system has no problem backing up and verifying, but we have difficulty restoring data from the backup sets. Since we rotate tape libraries, I would suspect worn tapes, except that I would expect to see problems verifying data if this were indeed the issue. What usually happens is at some point durring the restore procedure, the loader will display "idle" on it's activity window, while the Retrospect window will be stuck on "Seeking" or "restoring." Sometimes I get the -102 error, sometimes the system just stops responding. I've tried using both an Atto UL3D and an Adaptec 29160 card. I've also tried "clocking down" the SCSI card to 10 MB/Sec hoping this would make it more stable, but to no avail. Ideas and suggestions would be much appreciated.

alanrh Posted November 29, 2005 Author Report Share Posted November 29, 2005 Is Jaguar more "SCSI Friendly" than Panther? I'm thinking of going back to 10.2.8 to see if my situation improves. Link to comment Share on other sites More sharing options...
twickland Posted November 29, 2005 Report Share Posted November 29, 2005 The Adaptec card is not certified beyond OS 10.2.2, though we were able to keep ours working up until the last couple of Panther updates. The ATTO card should work. Go to ATTO's website (http://www.attotech.com) and check to see that you have the latest driver version and have installed any necessary firmware updates.

alanrh Posted December 1, 2005 Author Report Share Posted December 1, 2005 Went back to 10.2.8. Using Atto UL3D card with proper driver. Still have same problem. Log now showing error 205. Do I need to get all new tapes for furture backups? Link to comment Share on other sites More sharing options...
twickland Posted December 1, 2005 Report Share Posted December 1, 2005 You might try a test backup to a new tape, but in my experience, this kind of problem is more likely to be somewhere in the SCSI chain. (Bad tapes typically generate a 206 error.) Take a look at the SCSI troubleshooting tips in the user's manual. 50- and 65-pin SCSI cables have very tender pins, and it's not all that hard to bend a pin by misalignng the plug slightly during a card or device swap. A bent pin or other problems with the cable can cause communication problems of the type you're experiencing. Link to comment Share on other sites More sharing options...
