Remote Access to Local Tape Drive

Hi.
I seem to recall, many moons ago, a software utility that allowed a local tape drive to be accessed by a remote node.
Example: i have an AlphaServer 4100 that has an TZ89 tape drive attached. I would like to make the TZ89 accessible to another cluster (non-clustered with the 4100)
For the life of me I cannot remember the name of the utility.
Any one?

How about TCP/IP's RMT (remote mag tape) utility?

Re: Remote Access to Local Tape Drive

There's a DCL hack in the FAQ that can do something like this, if this is end-to-end VMS and you have DECnet around.

Restoration using this path is dicy, given the difference in the installation environment, but at least you'll have the data and can probably acquire a spare or can temporarily relocate the tape drive.

Look for "zt" in the freeware collection?

Personally, I'd look at Ebay for a used tape
drive.

Re: Remote Access to Local Tape Drive

We're running v5.4 - ECO 7 of ip on our AlphaServers and I believe the RMT utility first became available in v5.5?

Actually, after thinking about it a bit I think what I'm going to do is NFS serve/export the device I want to back up to the 4100 so it can do the tape backup from the export. The files are static (backup savesets) so I don't have to worry about any locking issues.

Thanks to all for the responses.

Re: Remote Access to Local Tape Drive

Steve's got a very good point. This is junk-grade hardware, so scrounging a TZ89 is likely going to be the cheapest fix. I see one TZ89N (which is the density-restricted variant) for US$50, and DLT 7000 and DLT 8000 drives are cheap, too.

Re: Remote Access to Local Tape Drive

Archive/Backup System (ABS) for OpenVMS comes with a remote tape drive server (RDF).

Not sure on which OpenVMS versions or architectures it is still supported.

Re: Remote Access to Local Tape Drive

Hi,

I think you are referring to RDF (Remote Device Facility).
This allows you to access the device on the remote node even if that remote node is not in a cluster with the local node.

The following link has some documentation on RDF -

Hope this helps.

No, it is in REXEC actually. I think it was introduced somewhere in UCX V4.1. Long time ago.
