Well, I got a 'why would you want to do that' message and the following
replies:

| I asked the DEC Ultrix folks at the Anaheim Decus about this and was

| years to make their cluster support work, so the relative few working
| on Ultrix have a lot to do!

| Actually, if you have followed discussions of using dual ported disks
| under Unix you will see how hard a problem a cluster would be to do
| right---how do you do disk block caching for the shared disks?
| 
| Since we really wanted the cluster, we had to order our 8600 with VMS;
| a REAL pity!

| I believe Dave Leonard (DEC) and members of his group are working on a
| driver for the HSC50. They are the ones who did the System V RA81
| driver. You might try contacting them thru DEC in Holmdel. We run 6
| VAXes with RA81/TU78 configuration and are anxiously (to say the least)
| awaiting word from Dave as to their progress.

The fact that nothing is available is about what I expected.
