Can't mount a cdrom. Pathetic.

Jackie Baron — Fri, 24 Sep 2004 09:46:01 GMT

Sounds lame I know but I've tried everything I can think of...here's the scenario:

I have a HP 9000 workstation with external SCSI Toshiba cdrom. I just fresh installed HPUX 11.00 onto the workstation from the cdrom. No problems there, just boot from alternative source and run the install. Then I needed to install some additional software once the base OS was on there. There are 3 disks in ioscan -fnC disk and /dev/dsk/c0t2d0 is my cd. BUT when I "mount /dev/dsk/c0t2d0 /whatever" I get the error "Unrecognised file system"...hmm!

I thought it might have been that the device was missing a SCSI terminator so I got one and stuck it on there...no change.
The cd media is fine because I mounted and read it on a wintel machine and my sun box. I tried other good media in the HP box but still the same message. I tried the mount -F cdfs option....nada!

Please help

Hi Jackie,

I find it strange that CD is on C0. On my servers C0 is for the Initiator...

Hope this'll help.

If you are shure it is c0t2d0, try recreating the device file.

# ioscan -fnCdisk
# insf -H hardware_path

What exactly is this CD?? What it contains??

Are you using the right path??

mount -F cdfs /dev/dsk/cxtxdx /cdrom

mount -o cdcase /dev/dsk/cxtxdx

Is this a HP Applications CD or some other type? The fact that you can read it on a wintel machine leads me to believe that it's a windows format and you're going to have to use pfs_mount or apply the RockRidge extension patches.

I'll quote from Merijn's faq at his website (or it's mirror, that is) http://mirrors.develooper.com/hpux/

" *

Do not use pfs_mount!. Install the Rock-Ridge extension patches instead and never worry about these problems. For HP-UX 11.00 you will need forget all about PFS and install PHKL_26448 (now superceded by PHKL_28060), PHCO_26449, and PHKL_26450 to have HP-UX recognize those file systems automatically on mount! For HP-UX 11.11 (11i) you need PHCO_25841, PHKL_26269, and PHKL_25760 (now superceded by PHKL_28025).

No need thereafter to use -o cdfs to mount anymore, provided you enter the CD drive in /etc/fstab like this:

/dev/cd0 /cdrom cdfs ro,rr,noauto 0 0"

Hi,

try swinstall without mounting the cd.
Choose 'Find local cd'.

OK Guys,

This CD is the Applications CD disk 4 of 5. I want to install the DCE Kernel Threads. I have tried to simply run swinstall and Find local CD and it quickly "homes in on" SD_CDROM directory and then says "no media in there" and that's it. There's nothing wrong with the media, I'm quite certain and I don't think there's much wrong with the drive seeing as I've installed the OS from it and can boot from it...ergo something in the OS is tripping me up.

Re: Can't mount a cdrom. Pathetic.

Pete Randall — Fri, 24 Sep 2004 10:24:24 GMT

In that case, forget RockRidge extensions (for now, anyway). Run your swinstall with the -s option: "swinstall -s /cdrom" and see what you get.

It may be stupid question but have you tried:

mount /dev/dsk/c0t2d0 /SD_CDROM

?

Gerhard Roets — Sat, 25 Sep 2004 02:21:07 GMT

Saw this before ;) Made me very freustrated.

Just a hunch before getting extremely exotic.

"mount -r /dev/dsk/c0t2d0 /whatever"

It could be that the disk has an hfs filesystem on it :P.

Bharat Katkar — Sat, 25 Sep 2004 02:33:21 GMT

HI,
This should work,
1. mount /dev/dsk/c0t2d0 /SD_CDROM
2. swinstall

If not try mounting as suggested by Gerhard.

Hope that helps.

Can you send us the "ioscan -fnCdisk" output?

Jackie Baron — Mon, 27 Sep 2004 04:39:13 GMT

Well here's what happens with the -r option:

# mount -r /dev/dsk/c0t2d0 /cdrom
/dev/dsk/c0t2d0: unrecognized file system
#

here's the ioscan output:

# ioscan -fnC disk
Class I H/W Path Driver S/W State H/W Type Description

This has me stymied!

Hi again,

very strange ... can you mount any other cd right now?

It seems to be the cdrom drive.

Can you add another drive?
Can you test the drive at another pc/ws?

Volkmar
*who don't want to ask if you've switched on the drive* ;-)

You should check if the CD-ROM Subsytem is compiled into your kernel. I never saw a kernel without it, but it is possible that it is missing.

try it as

mount -r -F hfs /dev/dsk/c0t2d0 /wahtever

Re: Can't mount a cdrom. Pathetic.

Paul Mai — Mon, 27 Sep 2004 05:33:35 GMT

Gerhard,

The filesystem for CDROM is CDFS not HFS.

Jackie,
Had you ensured that a CD is loaded into the CDROM before attempting to mount?

Re: Can't mount a cdrom. Pathetic.

Jackie Baron — Mon, 27 Sep 2004 05:35:30 GMT

I'm about to check that thread Eric, in th meantime here's the latest output:

# mount -r -F hfs /dev/dsk/c0t2d0 /SD_CDROM
/dev/dsk/c0t2d0: unrecognized file system

And everybody,

The cdrom IS powered on and there IS a good CD in there. It's app. CD 4 of 5.
