[mod.computers.vax] HSC load balancing with dual pathed disks

S211KENO@HTIKHT5.BITNET.UUCP (03/03/87)

While studying the Guide to VAXclusters about dual-pathed disks (connected to
2 HSC's) I began to wonder how to achieve load-balancing between the 2
HSC's if you use allocation-classes.
I would like one half of our dual-pathed disks have their primary path on
HSC1 and failover to HSC2 and the second half of the dual-pathed disks with
their primary path on HSC2 and failover to HSC1.
Assuming both RA81 port select buttons should be pressed to enable automatic
failover, the path that is chosen is probably arbitrary (the device-name in
the mount-command includes an allocation class which points to both HSC's).
Is it possible to mount a dual-pathed disk in such a way you have influence
on the choice of the primary path ?
We don't like pushing buttons every boot.
Any experiences/ideas ?
