SUMMARY -- mounting CD-ROM under Solaris 2.2

Sun Managers,

As usual I received many responses. Thanks to all.


The original problem was two-fold. Little experience with Solaris 2.x and
an unknown problem with Volume Manager.

I was attempting to bring up a SPARCclassic under Solaris 2.2 (my first).
Was able to install OS with no problem. Next, I wanted to install AnswerBook
to have access to manuals. Catch-22 situation....had problems mounting CD but
could not refer to manuals.

Did not know about Volume Manager at first. I suspect I confused the OS when I
tried to manually mount the CD with /etc/init.d/volmgt running. Once I received
some responses to my question I discovered that I could automatically mount other
CD's but not the AnswerBook CD. I was just about ready to order a replacement
when the CD mounted automatically. I haven't had a problem since.

I've included most of the responses I received in case there are details that
might help someone.

/sbin/sh /etc/init.d/volmgt stop will turn off
the volume daemon. this is the stoopid thing
that mounts all of you removable media (cd & floppy)
for you when you insert it. this prevents you
from being able to mount it yourself or using
your floppy for "tar". if you really hate it,
have your filemgr open and stuff in a floppy or
cdrom; a sub-filemangler will appear, and on one
of the pull-down menus is a survey form that you
can fill out and send to sun along with your comments
about how much you like this swell macinto.. i mean
new user-friendly behaviour.

Volume Management (new in 2.2) takes over the CD reader and the
diskette. When you insert a CD, the system automagically mounts
it. Look in /cdrom and you'll find a symbolic link or two, which,
if you follow them, will eventually get you to the contents of
the CD. Under normal circumstances, mount/umount is not
necessary. There is also a filemanager preference you can set
to have a new window pop open every time you insert a CD.

Your problem is due to conflicts with the new volume management features. By default volume management will automagically mount a CD on /cdrom/unamed_cdrom. You might see if you can just CD there.

You could also kill /usr/sbin/vold and then see if you can unmount it. The new device name is /dev/dsk/c0t6d0s0.
