Problems mounting cdrom

Ted Flanders — Thu, 05 Apr 2001 16:01:34 GMT

I am trying to mount my cdrom which I have done many times before. It is on my testbox. I use this command

mount -r /dev/dsk/c0t2d0 /cdrom

I get the message back
/dev/dsk/c0t2d0 :unrecognized file system

I am lost here, I have tried everything that I know. Can anyone help me out here? I did the ioscan and I know that is the right address. It will not let me mount or umount. Thanks

It look like the problem is with your CD - do *any* CDs mount...

HP-UX has rather poor support for non-ISO9660 format CDs

Most HP CDROMS for HPUX run the "cdfs" filesystem and HPUX doesn't support the standard Rockridge or PFS format that is used by most of the PC CDROMs.

What CDROM are you trying to mount?

I have mounted the cdrom before on this box, so I know that it has worked in the past. It is a Toshiba XM-4101TA. The box is a HP9000 E25 running HPUX 10.20

In this case you might also deal with a hardware problem. I would try to mount a standard HP Application CD and to see if it works.

I had a similar problem and I mounted the cd this way and it worked.

mount -o ro -F hfs /dev/dsk/ /cdrom

Hope this helps..

Ok....I get what you are talking about. I tried an hp cd that I knew I used before and it mounted right up. I have a cd with a different file system on it that isnt recognized. Duh.....oh well...I AM learning.
Thanks for your help.

The next step is for you to try pfsmount with your CD now. Refer to the thread "CDROM difficulty" here in the forum. There were some hints.

There is also a patch PHCO_15453 for the Portable Filesystem available on HPUX 10.20, if you run into more problems.
