This configuration works fine except for a few cases, and these are: 1. If I try to duplicate a directory tree on the same disk as the original directory tree using the command 'cp -opPrs old_dir new_dir' the machine may crash, and if it does crash it takes about 20 minutes for it to get down to the mnemonic debugger level. If I have the machine in service mode I get an error code that either is 80380018 [no resources available (OS/SCSI manager)] or 80080003 [disk controller time-out (OS/disk manager)]. 2. If there is heavy use on the disk an error might get logged that says, if you use lsyserr, "disk driver logic error (OS/disk manager)" and also "disk error recovered by some device action (OS/Recovered Disk Error Manager)". This has happened on 3 out of 5 machines which makes it, in my opinion, unlikely that there is a hardware error. BTW this error does not crash the machine. 3. We added a WangDAT to one of our 9000/425s and used SCSI-device 1 and are therefore able to use rbak/wbak with device m to access the DAT. The strange thing here is that if I make a wbak to the DAT with files from the local disk the machine is liable to hang and I get the error code 80080003 [disk controller time-out (OS/disk manager)] and the same thing happens if I rbak some files that were taken from one of our other disks to the local disk. This error does not happen if I do rbak/wbak to/from the other disks in our network, or if make a large wbak that includes all our disks, including the disk on the machine that has the DAT. Has anybody out there experienced the same thing or something like it, and is there a solution to our problems?
