Thread: Installing OpenVMS on a VAXstation 4000 VLC

    Default Installing OpenVMS on a VAXstation 4000 VLC

    Hi there,

    I just got a VAXstation 4000 VLC, and I'm having a little trouble installing OpenVMS on it:

    Code:
    %SYSBOOT-I-SYSBOOT Mapping the SYSDUMP.DMP on the System Disk
    %SYSBOOT-W-SYSBOOT Can not map SYSDUMP.DMP on the System Disk
    %SYSBOOT-W-SYSBOOT Can not map PAGEFILE.SYS on the System Disk
       OpenVMS (TM) VAX Version X7G7 Major version id = 1 Minor version id = 0
    %WBM-I-WBMINFO Write Bitmap has successfully completed initialization.

    Available device  DKA300:                          device type MATSHITA CD-ROM C
    %BACKUP-I-IDENT, Stand-alone BACKUP T7.2; the date is 23-MAR-2020 12:10:53.36
    $ BACKUP/IMAGE/VERIFY DKA300:VMS073.B/SAVE_SET DKA0:
    %SYSTEM-I-MOUNTVER, SABKUP$DKA300: is offline.  Mount verification in progress.
    It can boot from the external SCSI CD-ROM I have, but when I start the BACKUP command, it seems to think that the CD-ROM is offline. I'm using an AppleCD 300e drive, because that's the only SCSI CD-ROM I had around.

    Is it something about this particular drive, or is there some sort of diagnostics I can do? I used VMS (as a user) ages ago, but I was never an "admin" on a VAX before now. I've checked the install manuals and I can't find anything relevant.

    It's been a while since I did this on my 4000/60, but there's a couple gotchas when using consumer SCSI CD-ROMs with old workstation hardware. I think the AppleCD 300e is capable of handling CD-R media, at least if I'm recalling correctly and the Apple CD-ROM drive I used for years was a 300e. Probably what you're running up against here, though, is the requirement most old workstations have that the CD-ROM drive present itself as a standard 512-bytes-per-sector device, rather than the oddball ~2K-ish sector size native to the media. I don't recall if the 300e has a jumper you can set for this, but since I ended up having to just buy a newer IBM SCSI CD-ROM drive for the purpose, I'm going to guess probably not. Worth checking, though.

    Okay, thanks! It looks like the 300e doesn't have a jumper for that. I tried my Plextor 12/4/32 SCSI drive also, which does have a "block" jumper but the same error happens with it set or not set, it just happens during the initial device scan when booting off the backup disc instead of when you call BACKUP/IMAGE/VERIFY.

    I'll see if I can track down an actual DEC CD-ROM drive from this era, I suppose!

    I have an RRD45 in my 4000/60. This post says it is likely a Toshiba CDROM that supports 512 byte sectors. http://http://www.vcfed.org/forum/showthread.php?62168-CDROM-drives-supported-on-PDP11&p=501017#post501017

    Okay, solved this thanks to the pointers I got in replies here -

    I took a SCSI2SD v5 device, and set it to SCSI ID 1, emulating a CD-ROM with a 512 byte sector size, and put the ISO on the SD card.

    Everything booted and worked! Thanks for the help!

    So you were able to complete the install and boot VMS from the hard drive?

    What VMS version does it report when booted? I've been trying to install 7.3 on my 4000/60 and get the same device offline/mount verification error, but in my case it's usually reported on the destination hard drive (DKA100) rather than the CD-ROM.

    This system already has 7.2 and NetBSD 9.0 running nicely on it.

    Replying to my own post: I do see that you installed 7.3:

    $ BACKUP/IMAGE/VERIFY DKA100:VMS073.B/SAVE_SET DKA0:

    I'm wondering if, in the similar vein as your compatibility issue with your SCSI CD, I might have trouble with my SCSI HD.

    I have Quantum Harpoon 2.25 GB 2275W wide SCSI drives with wide-narrow adapters.

    Yes, once I got a proper sector size drive, it booted.

    It reports this version at startup:

    Code:
    OpenVMS (TM) VAX Version X7G7 Major version id = 1 Minor version id = 0
    This is from the OpenVMS 7.3 image I downloaded from HPE's Hobbyist FTP site.

    One note, I did replace the internal 125 mb hard drive with an 18 GB Seagate Cheetah SCSI drive I had here.

    Next step, sitting down and getting Compaq TCP/IP working.

    I've never had any issues using Plextor SCSI CD-ROM drives for OpenVMS installation, although now that I think about it, most of the time it has probably been with VAX systems with Q-Bus SCSI controllers. Maybe with the VAX 3100 desktop systems I that I have I have always used real DEC RRD4x SCSI CD-ROM drives.
