[fa.info-vax] VMS cluster problems

info-vax@ucbvax.ARPA (01/28/85)

From: ken@cit-vax (Kenneth Adelman)

	We are running VMS V4.0 with three -750s on a cluster with an 
HSC50 conrolling 3 RA81s, and each machine has an RA81 on a UDA50 as a local
disk. In the boot, each machine MOUNT/SYSTEMs the HSC disks, MOUNT/SYSTEM
the disk which are served by the other machines, and MOUNT/CLUSTERS it's
system disk again to make it available to the others. The SYSGEN
flags to inhibit rebuilding the system disk before it is set /SERVED
is off, as per the release notes.
	The problem: If all machines are turned off and booted in any
order all the disks get mounted on all the machines. However, if
one machine crashes, the others show the served disk an "HostUnavailable".
When the host comes back up, the disk shows a mount verification
in progress and then "MvTimeOut". Diskmount and remounting by hand removes
this. Any ideas?
