giraffe279 Posted April 30, 2002 Report Share Posted April 30, 2002 I have been running Retrospect Workgroup 4.3 (for Mac) successfully on a G3 mac for the last 12 months. This was connected to 5 Mac Clients and an Exabyte EZ-17 M2 tape library with the ADK 1.8 installed. I upgraded to retrospect 5 because I had to support OSX clients on the network. Now I am frequently getting an error 102 message (trouble communicating) from the tape library - tells me to switch tapes, but then I get the same message on the next tape. When I purchased, Dantz told me that I no longer needed an ADK with version 5. Any clues anyone? Thanks Link to comment Share on other sites More sharing options...

Guest Posted May 1, 2002 Report Share Posted May 1, 2002 Does this occur on local backups as well? If you revert to 4.3 does the problem go away? Link to comment Share on other sites More sharing options...
giraffe279 Posted May 4, 2002 Author Report Share Posted May 4, 2002 Thankyou for your help so far. Here goes: 1. Yes, it occurs on both local and client volumes 2. I uninstalled 5.0 on the OS9.1 server and re-installed 4.3. This seemed to work fine with both local and client volumes. I then re-installed 5.0 which worked OK the first time after installation but then on subsequent backups it reported the communication error as before. (Note: This was exactly what happened the first time I installed 5.0). I then tried a different mac as my server and had exactly the same results ( worked first time but reported communication error on subsequent backups. After that, I stumbled across something which seems to have fixed the problem (so far!): Because OSX seems to add a huge overhead to the clients in terms of folders and files (My 3 OSX clients all have 100,000+ files and folders each), I had to increase the memory allocation for retrospect, otherwise it would crash when trying to catalog the volumes. I have 320M available on the OS9.1 server, so I allocated 150M to retrospect. I found that the communication error seems to happen when I increase the memory allocation to Retrospect. On a fleeting hunch, I checked my memory control panel and noted that virtual memory was ON with an allocation of 320MB. I turned this off and re-started, and (so far) I have not experienced any problems! I will keep you posted on how this continues. Can you tell me though - does this solution make sense to you? I now have another problem however which I have placed in another post - "Version 5.0 network performance". Thanks Link to comment Share on other sites More sharing options...
mgolden Posted May 16, 2002 Report Share Posted May 16, 2002 We had the same problem here. Our fix turned out to be upgrading the firmware in the tape drive. I noticed that your firmware is the same as our original firmware was. If you continue to have problems you might want to get in touch with Exabyte's tech support and get the firmware upgrade as well. So far our has worked perfectly in Mac 0S 9 with virtual memory enabled. Mac OS X is another story. Not the same problem, but I'll save it for another post.
