Welcome to the wacky world of PFS, a 'workaround' to provide modern CDROM standards for HP-UX. PFS is called a user-level driver because it does not modify the kernel, but it performs this magic using NFS. It is not very stable and PFS should not be used on production machines.

The good news is that you are running 11.0 and you can now remove everything associated with PFS. Just download and install these 3 patches:

PHKL_26448
PHCO_26449
PHKL_26450

This requires a reboot and from now on, the CDs are mounted with the -orr option. Patches are available for 11i and will never be available for 10.20 (now out of production).

RIP PFS

PFS uses some parts of the NFS daemon to run.

The reason the cdrom disappeared when you logged out of your root session is because you didn't use the nohup option to run the daemons.

You really should have done:

# nohup pfs_mountd &
# nohup pfsd &

About the only option you have to recover now is to reboot, I think.

I would definitely take Bill Hassel's advice above and load the patches he mentions so that you don't have to worry about the stupid PFS stuff anymore.

Good luck.
