[comp.os.vms] Need help changing boot node on LAVC

lumsdon@dtoa1.dt.navy.mil (Esther Lumsdon) (10/05/89)

We have 2 uVAX II's. VAX2 is our boot node and VAX1 is a satellite node
on our LAVC. VAX2 has more Q-bus slots in it's cabinet, and we want
to make VAX1 our boot node, and devote VAX2 to stuff that will have
it rebooting too often to be our cluster boot node and disk server.

If we take our boot disk (an RD54) out of boot node VAX2 and connect
it to VAX1 as dua0:, will this essentially swap the identities of VAX2
and VAX1?  If not, then how might we accomplish this?

We're actually moving uVAX VAX1 from a BA23 cabinet to a H9642 cabinet,
and giving it a new RQDX3 (it has a 2 now), and a DEC-compatible M9405
Q-bus extender card, and upgrading to VMS 5.2 as well. I'm sure that
we need to do all this in stages, but I don't know how to divide the
work up. I'm not a hardware person!

Please, does anyone have any suggestions?  Our current cluster system
disk is an RD54, and I don't think it's dual-ported. I believe that
only our Ethernet (running DECnet) connects the nodes and allows the
disks to appear everywhere. (that, and MSCP).

I'll be quite grateful for any help!
Thanks!
