No VMScluster and TruCluster (is that what it's called?)
don't have much in common. They do not interoperate.
But you could add in a spare drive and drop VMS
onto that on you Alpha - you can boot VMS and it
will leave your Unix disks alone if you don't mount
them and vice versa.

Then you cluster you VAX with your Alpha and
and mount the CD and off you go. (It's that
easy if you've done it before, you'll probably need
a bit more help if you have not). For this to work
your prerequisites are working ethernets at both
ends and OpenVMS on both (same version saves
a bunch of hassle).

DELQAs are two a penny. I'd send you one
but shipping would be prohibitive from the UK.

If this is either a VAXstation 3100 or a VAXstation 4000
then obviously it will have SCSI and adding a CD should
be straightforward. If it is a VAXstation II/2000/8000/3500
then you'll still have problems (although if it's a VAXstation
8000 I'd like to have your problems :-))
