Problem mounting CD-ROM

[Gus Mestousis]

Running HP-UX 10.20 on a laptop. I can see the device when I do an ioscan:

# ioscan |grep CD
8/16/5.3.0 disk PLEXTOR CD-ROM PX-40TS

But I can not mount the device:

# mount /dev/dsk/c0t6d0 /SD_CDROM
/dev/dsk/c0t6d0: No such device or address

# mount /dev/rdsk/c0t6d0 /cdrom
mount: /cdrom: No such file or directory

# ls /dev/dsk
c0t0d0 c0t1d0 c0t2d0 c0t6d0

[Darrell Allen]

Does "ioscan -fnC disk" show c0t6d0 as the device file for the cdrom? Does it show CLAIMED?

Hi Gus,

run ioscan with the fnC option to see the driver.

ioscan -fnC disk

if no driver is shows up, then it may have not been create or may have been deleted?

insf -e #to recreate.

Hope this helps.

Run and ioscan -fnC disk and see what device file is assigned to your cdrom, then go from there.

Usually cdroms are /dev/dsk/c2t2d0 and your boot disk is /dev/dsk/c0t6d0.

I ran
#insf -e

Worked like magic!

# ioscan -fnC disk

Thanks everyone for the lightning fast replies!!!!

Hi Gus,

Looks like the device file for your cdrom should be c0t3d0 and not c0t6d0,

do a insf -e to create the device files. Then do a ioscan fnC disk to check the device file for cdrom. If you see the cdrom device file as c0t3d0, mount the cdrom using,

mount /dev/dsk/c0t3d0 /cdrom

Hope this helps.

Hi,

The device file you are using is different. Th CD Drive device file is /dev/dsk/c0t3d0 ! ( NOT /dev/dsk/c0t6d0 ). Try this:

# mount /dev/dsk/c0t3d0 /SD_CDROM

HTH,
