Is there a supported way to attach a Tape Drive to OpenVMS 9.2-2

Post by pocketprobe » Wed Mar 20, 2024 1:26 pm

Are there presently any supported ways to attach a(n LTO) tape drive to a system running 9.2-2?
Ideally via SAS/SCSI

   A physical (not virtual) tape drive?  I know nothing, but I doubt it. 
But I wouldn't be amazed if the answer depended on the exact type of
system on which VMS V9.2-2 was running.

   If you had such a tape drive, what would you do with it?  BACKUP can
deal with a save set on disk storage, too, for example.

Your assumption is correct, it is for backups. As to why LTO Tape? It's reasonably priced, especially for generations that fit within the current volume size limit for OpenVMS... and I've inherited a dozen or so tapes. Ultimately, it's for the same reason as to why I'm collecting VTs; I just think they're neat.

I've since moved my bare metal machine to a(n) HP(E) ML150 Gen9 which is very close to being a(n) HP(E) DL380 Gen9, and the question about supported configurations comes up, as asking sysman to configure the tape drive for use crashes the machine. If it's something to be explored I can post more information.

Please post the first page of the output from

$ analyze/crash
SDA> CLUE CRASH

You are traveling a path we have not yet tried, so I'm curious to see where things went off the rails.

Unfortunately on this machine it crashes so hard, that we're unable to make a crash dump. I'd question if it's a driver bug for the gen9 smart array controllers; In my post about running on bare metal, I was advised that it wasn't fully validated and was only really tested with one specific controller. With some cable trickery (and purchase of an cable adapter) I could probably see if the tape drive works on the P440 rather than an H240. I should also see if it behaves with the 1068e that I used in my other machine (Though that controller also stops working if there's more than 32gb of ram in the machine.)

I'm not sure if this except from the install media will help but here it is.

Re: Is there a supported way to attach a Tape Drive to OpenVMS 9.2-2

I moved the tape drive and controller to another machine, with a different controller type for the system disk. As requested.

Thanks for the output; I'll take a look at it on Friday to figure out where things went wrong.

Post by pocketprobe » Mon Apr 15, 2024 2:58 pm

I've finally had a cable come in to let me attach my tape drive to another controller (LSI 1068e) and I have the same crash occur. I've never had good luck with crashdumps with this controller.

One other thing I can try is passing through the controllers to a VM inside of ESXi and see if it still occurs.
