wobblewoo Posted May 24, 2010 Report Share Posted May 24, 2010 Hello All. The last two backups ive run on our SCSI LTO3 drive have failed. We use different tapes each day and the last two backups have suddenly started to fail. (the last one having over 1500 errors. Were running Retrospect (8.1 build 626) on a Xserve 10.5.8. The tapes are not barcoded. The drive is a Quantum lto 3 400gb/800gb hh ultra160 68pin scsi tabletop using a single Sony lto3 ultrium tape at a time. Here are the errors: May 20th From Retrospect: Script "Weekly Set 1" failed during automatic execution, error -102 ( trouble communicating). Please launch Retrospect and check the log for details. On this backup it completed 328Gb May 21st Script "Weekly Set 1" completed with 14 errors *File "/Volumes/Raid/Fileserver/CLIENTS/xxxxxx/xxxxx.psb": didn't compare > !Bad Media Set header found (0x91ff81ff at 170169152) > !Bad Media Set header found (0x92492492 at 170171067)... May 22nd Script "Weekly Set 1" completed with 1529 errors Similar errors to the night before: 5/22/2010 2:20:21 AM: Comparing CLIENTS > !Bad Media Set header found (0x8c5ddee8 at 2) > !Bad Media Set header found (0x21be910f at 24) > !Bad Media Set header found (0x2267588b at 37) Quote Link to comment Share on other sites More sharing options...
CallMeDave Posted May 24, 2010 Report Share Posted May 24, 2010 The drive is a Quantum lto 3 400gb/800gb hh ultra160 68pin scsi tabletop - Connected to what SCSI HBA on the other end? - Running what driver? - With what firmware? - For how long has this setup been running reliably? - Has anything changed since before the errors? - Have you cleaned the tape heads?

wobblewoo Posted May 25, 2010 Author Report Share Posted May 25, 2010 Thanks for your Reply Connected to a ATTO EXPRESS PCI-E UL5D DUAL CHANNEL U320 SCSI HOST ADAPTER. Using Configuration Tool 3.28 Running Driver v4.4.1 It says Flash Version April 10, 2009 The setup has been running fine for nearly a year, apart from an issue we are having with the tape names not being recognised. Thread here: http://forums.dantz.com/showtopic.php?tid/33852. The only thing we have changed is to change the backup script to eject a tape after a backup (although we have had successful runs after that) I have noticed that there was a 'Java for Mac OS X 10.5 Update 7' on the 20th. Coincides with the errors starting but cant believe its that.. is it? We have cleaned the tape heads. Does that help? Quote Link to comment Share on other sites More sharing options...
rhwalker Posted May 25, 2010 Report Share Posted May 25, 2010 I have noticed that there was a 'Java for Mac OS X 10.5 Update 7' on the 20th. Coincides with the errors starting but cant believe its that.. is it? That's a useful bit of information. You might want to try a regression test from a (spare drive) clean install of 10.5.x without that update. Or wait for the Retrospect big bugfix update ("real soon, now").

wobblewoo Posted May 25, 2010 Author Report Share Posted May 25, 2010 Big bugfix update eh. Looking forward to that, having a fair few problems with Retrospect 8 at the moment. Anyone else having any issues after that Java update? W Quote Link to comment Share on other sites More sharing options...
