cdrom mounting problems....

Jonathan Caplette — Fri, 12 Oct 2001 14:10:37 GMT

Hi guys...

I need your help again... :) I tried to mount a CD-ROM, but it keep showing me the filename in that form INSTALL;1

I tried those commands:
mount -F cdfs /dev/dsk/c1t0d0 /cdrom
mount /dev/dsk/c1t0d0 /cdrom
pfs_mount /dev/dsk/c1t0d0 /cdrom

all of those mounts have shown me the filename on the CDROM just like this: INSTALL;1 all the file on the CD....

Anyone have a clue on what command I should use to mount this???

Thanks
Jonathan

Something else that may have worked for you:

mount -o cdcase /dev/dsk/c1t0d0 /cdrom

I would try that. If it works GREAT. Use it instead of pfs_mount. I try to avoid the pfs stuff if at all possible.

I avoid pfs stuff because if you don't do things in just the right order, or mistakenly kill a pfs daemon or use umount instead of pfs_umount to unmount a CD you can cause yourself problems that take a reboot to fix.

The pfs daemons are not HP's greatest piece of work.

Hi Jonathan:

The 'pfs_mount' mechanism was developed by by Young Minds, Inc.

Never use the 'umount' command on a pfs-mounted CDROM. Use only the 'pfs_umount' command. Failure to do so will mean a reboot will be necessary. In addition, should you wish to kill the pfs daemons, do so in the *reverse* order that you started them.

Failure to follow these guidelines leads to ever-climbing CPU utilization, and non-responsive 'bdf' and 'ls' commands, and ultimately, a reboot.

A good document on pfs-style mounting is Technical Knowledge Base document #KBAN00000252.

Regards!
