Question Mount CD filetype Difficulty


I have a software install CD for an OpenVMS system. I am trying to read the files on it on USB CDROM player attached to my Linux PC by USB.
The reason for trying to read it on my Linux PC is the original support manuals have been lost and copies of the manuals in PostScript are on the CDROM disk.

lsusb shows the USB CDROM device.
When I try to mount the CD to read I get the message “…remote share not in ‘host:dir’ format…”

I have tried:

sudo mount –t nfs /dev/cdrom /mnt
sudo mount –t nfs4 /dev/cdrom /mnt
sudo mount –t auto /dev/cdrom /mnt
sudo mount –t iso9660 /dev/cdrom /mnt

Any assistance on syntax or why I can't mount the CD for reading would be appreciated.

See VM2Linux, especially ODS-2 tools and ODS-5 file system. On Debian-based systems, there's also package dnet-progs that includes such tools as dndir, dncopy, etc., but I doubt it includes anything that will allow you to mount an ODS-2 CD. Please correct me if I'm wrong.

Start with the basics
Code:
file -s /dev/sr0
fdisk -l /dev/sr0
parted -l /dev/sr0
wodim --prcap
dvd+rw-mediainfo /dev/sr0

iso9660 should have done it, it has support for the VMS type of filenames with versions.
(In VMS a filename can have versions, so you can have multiple versions of the same file in the same directory, like:
name.extension;1
name.extension;2
etc.).
The name without a version always revers to the highest numbered one, the (assumed) latest.

Mount CD filetype Difficulty - reply

Thanks for the info, still getting an error message:

File –s /dev/sr0 /dev/dr0: Files-11 On-Disk Structure (ODS-2); VAX/VMS or OpenVMS file system; volume label is TCPWARE0555

Based on another response it may not be possible to mount this CD because of (ODS-2)

Looks like OSD-2 maybe the issue.

VMS CDs were a little odd: ODS-2 formatted if memory serves. Aren't those manuals available on hp.com?

Glad to see some VMS sites still alive and kicking. (I wrangled LAVCs back in the day.)

The CD contains the manuals for a product called TCPWARE. TCP/IP is configured and running as part of TCPWARE and not as the native VMS OS.
show networks in VMS gives nothing but blank information.
Running show networks in the TCPWARE utility NETCU show the networks with the interfaces and the IP addresses assigned, gateway, dns, etc.
Just trying to get a handle on a system that has not be supported by anyone in the company. In that regards you can say VMS is stable since it has been running for years without an administrator.

Thanks for the response.

Think you can get it to work.

I get the feeling I had same issue but just downloaded some old project to mount it read only. Had to switch distro's to make it easier but I know I did it a 2 or 3 years ago. Wasn't hard to get it up and running.
I also had a emulator running a dd'ed image of the drive but I'm pretty sure it was a simple filesystem addition maybe on github even. It was a read only mount.

I'm only vaguely familiar with TCPWARE. TCP/IP was available on the VMS boxen I was using up until ~2000 using a product call "UCX". It was a bear to configure and tune and I recall spending a good deal of time working over the phone w/ a UCX expert diagnosing performance problems with that package. I know a consultant who still works in the VMS arena if you have any really strange problems come up. There's also the PARSEC Group who specialize in OS support of older DEC/Compaq/HP systems (VMS, Tru64, etc.)---I've had occasion to work with them in the past and they know their stuff.

Cheers...
