I have been trying to mount a burned CD on a Intgrity system with Open VMS 8.3, but the system won't mount it.
HPOCC $ MOUNT /MEDIA=CDROM HPOCC$DNA0 OCC_V551 %MOUNT-I-OPRQST, medium is offline %MOUNT-I-OPRQST, Please mount volume OCC_V551 in device _HPOCC$DNA0:
It says the medium os offline, yet when I look at the device; HPOCC $ SHOW DEV HPOCC$DNA0: /FULL
Disk HPOCC$DNA0:, device type TEAC DV-28E-N , is online, file-oriented device, shareable, available to cluster, error logging is enabled.
Error count 0 Operations completed 6590 Owner process "" Owner UIC [SYSTEM] Owner process ID 00000000 Dev Prot S:RWPL,O:RWPL,G:R,W Reference count 0 Default buffer size 512 Total blocks 79392 Sectors per track 17 Total cylinders 292 Tracks per cylinder 16
Also the /OVER=ID and the /NOASSIST do no change it.
Interestingly, the Integrity system will mount other CD's, and the ALPHA systems we have with VMS 7.3 will mount the CD-R. It's just the CD-R that won't mount on the Integrity.
Here is what I got using an HP "Layer products" CD HPOCC $ MOUNT /MEDIA=CDROM HPOCC$DNA0 I64DOCFEB071 /noassist %MOUNT-I-WRITELOCK, volume is write locked %MOUNT-I-CDROM_ISO, I64DOCFEB071: (1 of 1) , mounted on _HPOCC$DNA0: HPOCC $ SHOW DEV HPOCC$DNA0: /FULL
Disk HPOCC$DNA0:, device type TEAC DV-28E-N , is online, allocated, deallocate on dismount, mounted, software write-locked, file-oriented device, shareable, available to cluster, error logging is enabled.

Volume Status: ISO 9660. Members of this volume set are HPOCC$DNA0: (rvn 1).
and here is a MSDN .NET disc
HPOCC $ MOUNT /MEDIA=CDROM HPOCC$DNA0 DN600ENU1 /noassist %MOUNT-I-WRITELOCK, volume is write locked %MOUNT-I-CDROM_ISO, DN600ENU1:DN600ENU1 (1 of 1) , mounted on _HPOCC$DNA0:
the first step I would try is MOUNT/FOR DNA0: This would skip all file system related access and just make sure that the CD can be read at all. DUMP/BLOCK=COUNT=n DNA0: would then show, if the first couple of (n) blocks of the disk can be read.
$ SHOW DEV will most likely show the DNA0: as online, as it could be configured. This does NOT implay, that the volume inserted in the CD/DVD driver can be read. A read QIO can fail with a status, whioch would lead the driver to return SS$_OFFLINE.
There are so many things that can go wrong when burning CDs, it hard to say what actually went wrong.
It is important to remember that the CD can be mounted and read on an ALPHA with VMS 7.3. So the CD was created correctly. The problem is with the Integrity with VMS 8.3 refusing to mount it.
Try a different drive, and try a different batch of disks. Right now, the most likely candidate here is something in the driver or in the drive itself.
There have been various ECOs released for OpenVMS V8.3. I'd start there.
I'd also try different formulation for the CD-R, as there have been cases of media-level incompatibilities. I don't know what the current firmware revision for the TEAC DV-28E-N DVD-ROM drive might be, but that's another path to investigate.
Then escalate to HP services.
FWIW, the /MEDIA=CDROM is only needed when you want to override the particular path used to mount a disk, and force MOUNT into the ISO-9660 path.
If this disk was recorded on a Microsoft Windows platform, ensure that it uses strictly ISO-9660:1988 and does not use ISO-9660:1999 nor any of the various extensions. Most Windows tools will use extensions. (But if it worked on an older OpenVMS Alpha box, this probably isn't it...)
I've posted details of CD recording on OpenVMS at http://64.223.189.234/node/28 Details of what and how you've recorded this disk would be useful, too.
