CD Drive Masquerading as a Tape Drive

[bladesman]

Hi All

Any one ever come across this.
Have a tape drive installed on the system which has been working fine.
Have a power outage on the server which shutsdown the sever,
when you reboot the tape drive is in a defined mode and in it place is another cd drive , if you remove the offending cd drive from the configuration and run mkdev -l rmt0, get back error message

Method error (/etc/methods/cfgsctape):
0514-051 Device to be configured does not match the physical
device at the specified connection location.

if you run cfgmgr it just brings back the cd drive.

rmt0 Defined 11-08-00-0,0 SCSI 4mm Tape Drive

cd0 Available 11-08-00-1,0 16 Bit SCSI Multimedia CD-ROM Drive
cd1 Available 11-08-00-0,0 Other SCSI CD-ROM Drive


Any idea's as to how i can get the system to recognise the tape drive again.

Cheers

If the tape is on the same scsi adapter as the CD at 11-08-00 and has a scsi address of 0 (the real CD being scsi ID 1) then either there is a problem with the scsi adapter or the power outage has toasted your tape drive (and possibly your CD drive / scsi adapter) such that cfgmgr is picking up details of the CD drive whilst trying to configure the device at address 0.
Pull off one device at a time (with the power OFF) and check what can be configured.
Can you still use the CD?
Can you change the scsi ID of the tape and see what configures?
