how to mount and read a cd-rom

Hey specialists.
I would like to mount a cd-rom and read the content and finally install the c compiler.
I mount the cd drive with:
Wal > mount dqa0: /forei
%MOUNT-I-MOUNTED, ALPHA0732 mounted on _$1$DQA0: (SRVEB4)

and can see the device:
Wal > sh dev d
$1$DQA0: (SRVEB4) Mounted alloc 0 ALPHA0732 0 1 1
but when I try to read the cd rom, this error occur:
Wal > dir dqa0:[000000]
%DIRECT-E-OPENIN, error opening DQA0:[000000]*.*;* as input
-SYSTEM-F-DEVFOREIGN, device is mounted foreign

any ideas?

Hi Dario,

If you're gonna try a DIR DQA0:[000000] command, you shouldn't mount the CD /FOREIGN. Simply mount it privately:

Doing a MOUNT/FOREIGN to verify the volume label is fine, however, you will not be able to access the CD-ROM as a file structured device.

After doing the MOUNT/FOREIGN to get the volume label, DISMOUNT the device and then do a MOUNT DQAO: to mount the disk privately (if you want it to be available from multiple logins or DECterm windows, and you are on a suitably privileged account, do a MOUNT/SYSTEM command.

If you are mounting the CDROM for use in a single session, you can also do a MOUNT/OVERRIDE=ID command instead of the above sequence of commands.

Also check if that CD-ROM is the correct one for the C compiler. Offhand, I do not remember which CD-ROM has the C compiler kit on it.

I hope that the above is helpful.

Re: how to mount and read a cd-rom

Re: how to mount and read a cd-rom

That kit looks to be an OpenVMS Alpha operating system distribution kit, and those kits do not contain a C compiler. This based on the ALPHA0732 volume label.

AXPBIN[mmm][yy] is the usual volume label for an OpenVMS Alpha Layered Product (ConDist) kit.

There are full descriptions on how to get at distro kits. The OpenVMS kit is in the installation manual for OpenVMS itself. The layered product kits have an insert, and AFAIK this insert and related materials are also available on-line at the distro site.
