Mounting Issues

[Amrit Rao]

Hi,
When I mount my cdrom using the following command. I get the following errors.

mount /dev/dsk/c0t0d0 /cdrom mount: I/O Error

What are the possible reasons that I could get the above error.

Regards,
Amrit

Three possible reasons that I can think of:

1) You have a hardware problem.
2) The hardware device your using is incorrect. (please provide output of)
# ioscan -fnC disk
3) There is no CD in the drive.
4) The CD cannot be read.

I meant four .... I neveer could count up to ten ... (can't spell either ....)

Hi Amrit,

Are you sure it is /dev/dsk/c0t0d0 and not c0t1d0 ?

Check output from
# ioscan -fnkC disk

Hope it helps,

Robert-Jan.

Hi Robert,

I am sure the device is c0t0d0.

Hi,

Check with "ioscan -fn" that the device is CLAIMED.
Also check with "ll /dev/dsk" that the device file is correct.
Try also using "swinstall". Move to the tab "Find local CD", click Enter and see what happens.

Hope this helps.
Kind regards,
Zigor

Can we see the ioscan output please ....

It is pointless trying to run 'swinstall' if the CD cannot be mounted.

Have a look at this posting also, it has a few more possibilities, more than I can type. Have you tried a different CD to try and mount?

Hi Guys,

Looks like I burnt the CD incorrectly. I would burn a new CD and hopefully the problem disappears.

Thanks for the info.

Amrit.

Does it work any better with '-o ro' option on the mount?

[Bill Hassell]

Can you mount an HP CDROM such as the Core opsystem or one of the Application CDs? Note that there are a number of CD formats that HP-UX cannot read (ie, Joliet). The -o ro option may help convince the driver that the CD is in a useable format. Older or unpatched versions of HP-UX will not read RockRidge extensions correctly without the (now obsolete) PFS tools.
