Mounting CD-ROM on HP-UX

[Manjunath Shastry]

I normally mount cdrom on HP-UX 11.0 with the following commands

/usr/sbin/pfs_mountd &
/usr/sbin/pfsd &
pfs_mount /dev/rdsk/c0t0d0 /cdrom

However, I had to use a different mount command to mount an Application CD, which is as follows

mount -o cdcase /dev/dsk/c0t0d0 /cdrom

I would like to know the difference between both the mount commands and the role of pfsd.

Simply put, pfs* is a pice of software from a company known as Young Minds Inc. which HP used/uses.
The mount command is a standard UX command, thaht has options for things such as changing case.
With some recent patches for hP-UX, you no longer need to use PFS, which was needed for ISO style written CD's or CD's that did not have a "standard" UX format in the file names. You now only need to use the normal mount commands, thus alleviating many of the inherent problems that occur with using PFS.

The mount command becomes:
# mount -F cdfs -o rr /dev/dsk/c#d#t# /cdrom
