CLUSTER_CONFIG dows a rather good job in setting SYSGEN parameters. If
you have
a tape or cartridge drive on the VAXstation then you might want to set
TAPE_ALLOCLASS
to the same value as ALLOCLASS. May be changing the value of LOCKDIRWT
does improve
performance on the VAXstation, though I doubt it's going to make a
noticable difference.
What may interest you is the output of $ SHOW CLUSTER/CONT on the Simh
system and ADD CIRCUITS and ADD COUNTERS.
Then boot the VAXstation into the cluster.
