Installation//I can't see my CDROM!!!

UNIX Solaris
1

Hi All,

Here's one that's got me confounded. It's on a Sun Fire 280R running Solaris 9.

Problem: After some sysadmins (remotely) decided to disable the automount feature on one of my servers, I can't mount cdrom drive, nor the data on the disk I need to install.

Steps so far: (Comments in green)

$ sudo mkdir /mnt/cdrom (which created my directory to write to)

$ ls -al /dev/sr* |awk '{print "/" $11}'
(which gave me the name of the device - /dev/c0t6d0s2)

$ sudo mount -F hsfs -o -ro /dev/c0t6d0s2 /mnt/cdrom
mount: No such device
mount: cannot mount /dev/c0t6d0s2 (which are the error messages)

I have the correct permissions to run sudo commands on this but haven't got an idea why I can see the device but can't mount it. I'd like to try to figure this out before going and asking the v. helpful sysadmins to do it for me so, as usual...

Any suggestions gratefully appreciated.

Thanks all!

Best Regards,

Ger

The last time this came up, the cd was not in the cd drive! Are you sure that the cd drive is ready?

Shouldnt it be /dev/dsk/c0t6d0s0

Try this:

sudo mount -F hsfs -o -ro /dev/dsk/c0t6d0s0 /mnt/cdrom

Hi Perderabo,

Yes, the disk is in the drive, is readable and has installed correctly on all my other Sun machines.

And yes, that was the first thing that I checked :slight_smile:

Thanks,

Hi Dangral,

Thanks for your suggestion: unfortunately here's what I get...

$ sudo mount -F hsfs -o -ro /dev/dsk/c0t6d0s0 /mnt/cdrom
mount: /dev/dsk/c0t6d0s0 on /mnt/cdrom - WARNING unknown option "-ro"

Any ideas?

Regards,

Ger

$ sudo mount -F hsfs -o ro /dev/dsk/c0t6d0s0 /mnt/cdrom
mount: /dev/dsk/c0t6d0s0 on /mnt/cdrom - WARNING unknown option "-ro"

no '-' before the ro

Hi Reborg,

Thanks.

Tried both with and without - no joy!

Sorry!

CDROMs should be mounted read only automatically, so try this:

sudo mount -F hsfs /dev/dsk/c0t6d0s0 /mnt/cdrom

On a SunOS 5.9 system I killed vold and made a /mnt/cdrom. Then I tried:
mount -F hsfs -o -ro /dev/dsk/c0t6d0s0 /mnt/cdrom
mount -F hsfs /dev/dsk/c0t6d0s0 /mnt/cdrom

and both worked for me. That is interesting because the device name is wrong. It should be /dev/dsk/c0t6d0s2. I retried both forms with the right name. Both still work.

geralex, if you are still having trouble, post the results from:
sudo mount -V -F hsfs -o -ro /dev/dsk/c0t6d0s2 /mnt/cdrom

Hi All,

So on one last try this morning the CD was inserted, read, mounted and unpacked without any issue or explanation as to why this being so awkward last week. Bugger.

Perderabo, dangral and reborg: Many thanks for all your work and suggestions and apologies that there's no evidence of what went wrong or postable solutions for this one!

Best regards.

Ger
