It seems the majority of people felt this was a problem with the Volume
or Vold. To start vold, it was suggested to run this command:
   /etc/init.d/volmgt start

Also, if you want to mount the cd manually, it was suggested to kill off
  either by this: /etc/init.d/volmgt stop OR Vold: /etc/rc2.d/S92volmgt

If vold is running, it was suggested that the cdrom should already be mounted,
in the cdrom directory.

It was also suggested to run the df -k command, to look at the disk entries.

It was also mentioned that if I was trying to mount the CD-Rom manually,
volume management must be disabled, or I will see a lot of "permission"
error messages.

One last item on Vold--it was mentioned that the file S92volmgt is the
script which launches vold at boot.

There were a few suggestions to do a re-configuration reboot, then using
the mount all, and volcheck commands as follows:
     boot -r ( to boot with new devices added to the system)

Finally, I received many suggestions on the syntax of the mount command, and it
was strongly suggested that in order to mount the cd manually, the volume
manager should be stopped first.
  /etc/init.d/volmgt stop

Examples of the suggestions for the mount command syntax are as follows:
  mount -F hsfs /dev/dsk/c0t6d0s0 /cdrom ( This is one I believe I tried,
but it may not have worked fro me--due to the above mentioned note to stop
the vloume manager)
  mount -r -Fhsfs /dev/sr0 /cdrom
  mount -f hsfs -o ro /dev/dsk/c0t6d0s2 /cdrom
  mount -F hsfs -o ro /dev/sr0 /cdrom
  mount -F hsfs -o ro /dev/dsk/c0t6d0s0 /cdrom
  mount -rt hsfs /dev/sr0 /cdrom
  mount -r -F hsfs /dev/sr0 /cdrom
  mount -F hsfs -o ro /dev/dsk/c0t6d0s0 /mnt
  mount -o ro -f hsfs /dev/dsk/c0t6d0s0 /mnt
OR for UFS parts on the solaris install cdrom, it was suggested:
  mount -o ro -f ufs /dev/dsk/c0t6d0s1 /mnt
  mount -F hsfs /dev/sr0 /cdrom
  mount -o ro -F hsfs /dev/dsk/c0t6d0s0 /cdrom

So, as you can see, I received many replies to my query concerning cd-rom
and mount, and I now have many answers to explore and try. All of your
were quite helpful and informative. I do have the book--Essential System
Administration--which was in one of the responses--but I did not find
concerning the solaris Volume Manager--but I will look again.
   I am posting the original question at the end of this message, and I am
posting this summary so your answers will go into the archive--maybe it
will help someone out down the road.
     Thanks to all of you for your suggestions, and for this list.

   Hi Sun Managers:

First, I preface my question by stating I am a "newbie" to the ranks of
administering Sun's and new to unix in general. I have looked at the archives
on latech's web site, but did not find any specific info on this, so here
goes my question:
   I have been attempting to mount a cd-rom on our server. The server is
Solaris 2.5.1, with the latest 2.5.1 cluster patch update installed. I
have been trying various commands--so far unsuccessfully. I have tried :
" mount hsfs /dev/sr0 /mnt"
"mount -F /dev/dsk/C0t6d0s0 /cdrom" (Tried this without the -F option also)
"mount -F /dev/dsk/c0t6d0s0 /mnt/cdrom" (Tried this without the -F option also)
and I have also tried the rmount command with this syntax:
"rmmount /dev/cd0/ /mnt" ( have tried this with cd6 replacing cd0)

If it helps at all, these are the entries in the /etc/rmmount.conf file:

 Removable Media Mounter configuration file.

# File system identification
ident hsfs cdrom
ident ufs cdrom floppy pcmem
ident pcfs floppy pcmem

# Actions
action cdrom
action floppy

FYI: I have been successful in getting the server to boot from the cd-rom,
so I am sure the block factor is set to 512K--but it is a non-sun cd-rom,
so I was wondering if that is the problem? , Or do I not have the proper
  I apologize for asking for help with such a trivial problem, but I have
been attempting this for a couple of days now, without any success.
Thanks in advance for your help!
