Hi.  Has anyone out there successfully used the TMSCP protocol
to serve tape devices across a VAXcluster?

I have 2 VAXstation VLCs and 1 VAXstation 3100 in LAVC; all are
running VMS 5.5-1.  All have SCSI drives, which are served to all
nodes in the cluster.

Today I connected an 8mm tape drive (from TTi) to one of the VLCs,
and the device shows up locally, but not across the cluster.  The
TMSCP server is enabled on all nodes, and the SYSGEN parameter
TMSCP_LOAD = 1 for good measure, even though that is the default
setting for all nodes.  The tape drive is also SCSI and works fine
on the local node.

Can anyone see a step that I might be missing?  I would figure that
bringing up the tape drive across the cluster would be as easy as
the disks, but something's missin'.

Thanks in advance for any help!!

EO

The TMSCP server ONLY works for TMSCP tape devices (i.e. ones with device
names of MU).  This restriction may be removed sometime in the future, but for
now we are stuck with it.

See.  You know.  When you got VMS V5.5-1.  I mean when you ORIGINALLY
got it.  Like you know.  The tape?  It had like stuff on it.  You know,
files and stuff.  Maybe even RELEASE NOTES.

And they had some stuff.  You know.  Words.  Sentences.  Release
notes type sentences.

AND ONE OF THEM SAID THAT SCSI TMSCP IS NOT SUPPORTED YET.

	Fixed in 5.5-2 (NOT HW, 5.5-2 proper)
