Question : Novell 4.11 crashes when opening scsi cdrom drive

We have a 533 mhz pentium with 256 megs of ram that has Novell 4.11. We have a juke box with 7 scsi cdrom drives connected to the connected to the novell server with an adaptec card 1000. The 7 drives contain various CD's that we access. They are mounted in Novell and and the Logon script mounts drive letters to them. Novell boots from a scsi raid

One CD is mounted to drive L. Twice today when I opened drive L from my desktop it froze ofter opening it. I could see the contents of the drive but could do nothing else after it froze.
When I went to the Novell server it had crashed to dos with the following errors

General failure reading drive C
abort, retry,fail

After hitting abort error continued

General failure reading Drive C
invalid command.com

Cannot load command, system halted.

Novell 4.11 has a dos 6.22 partition that it boots from. Once Novell was running I did not think it used dos. When a client trys to access a scsi cdrom drive from his workstation does Novell go into dos to operate the cdrom drive?

If the scsi cdrom drive, or the juke box were not working well I could see my computer not being able to open the drive, but I've never seen something like this crash a server outright.
Those errors are real basis dos errors. I thought novell only used dos to boot. I did not think it relied on it once it was working.

After rebooting Novell comes up fine, does not even run Vrepair, but I'm going to rem out the mapping to drive letters till I figure this out.  Is this most likely a hardware problem that
pertains to the cdrom drive in the juke box or the juke box itsself rather than a novell problem?

After everyone is gone I'll check to see if this happens when I open other drives in the Juke box. All this happened from my workstation. Nobody was near the Novell Server when it happened.

Answer : Novell 4.11 crashes when opening scsi cdrom drive

You can access the abend.log file from your workstation or from the server.  If you use the server type load edit sys:system\abend.log.  If you use your workstation make sure you use notepad or wordpad to open it.

Do you have administrator rights to the volume.  Under the sys: volume system is what novell for the autoexec.ncf and startup.ncf so there is a lot of stuff there.  

First boot device should be the RAID card.

Do the other CD drives work correctly?
