Nicolaus Posted June 21, 2002 Report Share Posted June 21, 2002 I have trouble with the following setup: OSX server running 10.1.4 Retrospect Workgroup 5.025 +Driver update Tandberg SDLT 220 Super DLT drive connected via a Adaptec 39160 card. External firewire drive. Retrospect used to run just fine until I swapped a normal DLT drive for a new Tandberg Super DLT. Two scripts run every night: First the boot disk gets backed up to file on the external firewire drive. This works fine every time. Then at 10 pm the DLT drive should back up the RAID tower (approx 85 GB of data) - but nothing happens. I can change the script to back up once during work time and it seems to start ok, backs up at 300MB per minute. Yesterday I completely removed retrospect and re-installed it, created new scripts and sets. It still does not work on schedule, but works when you carry out a immediate backup. Any ideas what else I could try? Many Thanks Nick Link to comment Share on other sites More sharing options...
IrenaS Posted June 21, 2002 Report Share Posted June 21, 2002 Have you tried recreating the scripts from scratch? Have you changed any preferences in the Retrospect Special > Preferences? Try setting Retrospect to "Stay in Retrospect" (the Unattended preferences). Link to comment Share on other sites More sharing options...
Nicolaus Posted June 24, 2002 Author Report Share Posted June 24, 2002 I have replaced the scripts, and backup sets. I have set Retrospect in "Unattended" to stay in retrospect. No other settings were changed. The Drive backed up twice half way only and then stopped and crashed the os X server. Again in the morning all you get is the spinning wheel, nothing else. There is no other entry in the log than time, starting backup, copying volume.. Why would it stop half way? Link to comment Share on other sites More sharing options...
CallMeDave Posted June 24, 2002 Report Share Posted June 24, 2002 In reply to: The Drive backed up twice half way only and then stopped and crashed the os X server. What do you mean by this statement? Does the server no longer serve web pages or shares? Can you connect to the machine from another machine via ssh? Can you view a 'top' session to see what's running and what's not? Dave Link to comment Share on other sites More sharing options...
Nicolaus Posted July 1, 2002 Author Report Share Posted July 1, 2002 The OSX Server backs up 1/3 to 1/2 way, then in the morning the Server displays the Retrospect window which shows you how far it has backed up. The rest of the screen displayed looks ok, you cannot access the file menus or the apple menu. Force quitting does sometimes work, but most of the time it does not respond. Just the spinning wheel. Users cannot log on to the server and the web server stops. I have replaced the SCSI cable with a new one and also the terminator. SSH/remote login is not switched on at the moment. Will enable ssh and look. Link to comment Share on other sites More sharing options...
IrenaS Posted July 2, 2002 Report Share Posted July 2, 2002 This sounds like a very typical device hang then. Can you provide a bit more detail on your hardware please? Computer Model and speed OS X version and build Device (from Retrospect's Configure > Devices > Device Status window) Device firmware (in the version column of the Device Status window) Device interface Media brand and size Other Devices Adapter Card firmware Adapter Card driver for OS X Pin configuration for device and card.

IrenaS Posted July 9, 2002 Report Share Posted July 9, 2002 And the pin configurations of the card and the drive? Thanks. Link to comment Share on other sites More sharing options...
Nicolaus Posted July 11, 2002 Author Report Share Posted July 11, 2002 The pin config is 68 pins on both the card and the Dlt drive. thanks, Nicolaus Link to comment Share on other sites More sharing options...
IrenaS Posted July 11, 2002 Report Share Posted July 11, 2002 I'm sorry I didn't catch this before, but it looks like you're using the latest Adaptec driver for the card, which we've seen to be problematic. Here's a Knowledgebase entry that gives instructions on how to revert the driver: http://www.dantz.com/index.php3?SCREEN=knowledgebase_article&id=852 If this doesn't help, here's a Knowledgebase entry that takes you through some preliminary SCSI troubleshooting: http://www.dantz.com/index.php3?SCREEN=knowledgebase_article&id=839 Link to comment Share on other sites More sharing options...
Nicolaus Posted July 12, 2002 Author Report Share Posted July 12, 2002 Irena, The configuration worked fine with a different DLT drive, which was not LDV and of smaller capacity. The driver was the same. The SCSI cables and terminator have been replaced to rule out SCSI problems. Are there LDV device problems with OSX?

IrenaS Posted July 15, 2002 Report Share Posted July 15, 2002 From my experience, if the device is LVD you have to have an LVD-SE terminator on it (it's usually printed on the terminator). I've seen cases in which an HVD terminator was used: it fit the connection but just didn't work. Link to comment Share on other sites More sharing options...
Nicolaus Posted July 18, 2002 Author Report Share Posted July 18, 2002 I have checked the terminator, it is the 2nd one I tried, both of them were LDV SE terminators. I have tried ringing tech support as well (UK 0800 169 7764) but all I ever get is a message telling me the opening hours and I should call back later. Can you offer some advice or escalate this problem for me, please? Many thanks Nicolaus Link to comment Share on other sites More sharing options...
