Hi,
I have installed a red hat 3 EL
I have this scsi card:

scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36
<Adaptec 3960D Ultra160 SCSI adapter>
aic7899: Ultra160 Wide Channel A, SCSI Id=7, 32/253 SCBs

scsi1 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36
<Adaptec 3960D Ultra160 SCSI adapter>
aic7899: Ultra160 Wide Channel B, SCSI Id=7, 32/253 SCBs

So how can I found the device /dev/... to mount it...no sorry to use dump for example or tar
Thanks

Luis

Make sure the SCSI tape module st is loading.
The tape device will be /dev/st0 & /dev/nst0
To check the drive enter this command.
mt -f /dev/st0 status

Hi,
so I beleave this result is good?

SCSI 2 tape drive:
File number=0, block number=0, partition=0.
Tape block size 0 bytes. Density code 0x50 (no translation).
Soft error count since last status=0
General status bits on (41010000):
BOT ONLINE IM_REP_EN

Can I test a tar -c /home?

Hello,

[root@aleph16 root]# mt -f /dev/st0 status
/dev/st0: No such device

and today the result is not the same...what can it be?
Thanks

Is the SCSI controller recognizing the DAT?
Is linux recognizing the SCSI controller and tape drive?
Check to make sure the SCSI modules are loading.
