Mounting Cdrom Drive In Guest Domain running 1.0.3

Question

Folks,
I have followed the Admin guide on how to export Cdrom/Dvd drive from Service Domain to Guest Domain, however once allocated to the guest domain we are unable to mount the device. Any help is appreciated.
Here are my bindings

We can see the exported cdrom volume in /dev/dsk as a new device and also at the ok prompt after running devalias.
However, we need to mount this device so that we can install software in our domain. All our attempts at mounting just hang and I end up having to stop/start the whole domain. ?
Is there an easy way to mount cdroms/dvd drives in a guest domain ?
TIA

Answer 1

There is an recently filed bug where DVDs (and ISO images) which do not have a VTOC in their disk label
fail to be mountable in the guest domain (e.g. application software DVDs as opposed to OS installation images).
6708257 DVD-ROM (not OS installation disk) can not mount from guest domain of LDOM 1.0.2
# mount -F hsfs /dev/dsk/c0d1s0 /mnt
mount: I/O error
mount: cannot mount /dev/dsk/c0d1s0
It's strange that you are getting a hang though (the reported error is an I/O error).
Are there any messages in /var/adm/message of the control domain?
What OS/patches are running on the guest and control domains (i.e is 127127-11 installed on both) ?
I've just had a thought though, exporting the DVD device as a slice instead may work
(it works for me on an ISO image but my machine is 1000s of miles away so I can't stick DVD in it
to try out)
e.g. ldm add-vdsdev options=slice /dev/dsk/c1t0d0s2 cdrom@primary-vds0
