  Cluster Multipath SCSI and HSZ controllers? 
 The Question is:
 
What version of Alpha OpenVMS supports scsi multiple bus failover with HSZ50
 controllers?
 
I have a dual-redundant HSZ50 (HSOF 5.2)configuration connected to my AS4100
 via a single KZPSA. I am running OVMS 6.2-1H3 and would like to configure an
 additional KZPSA to this redundant HSZ50 configuration. This is required to
 increase the system avail
ability (eliminate the single point of failure with the single KZPSA)and SCSI
 performance.
 
 The Answer is:
 
  OpenVMS Cluster multipath SCSI operations require HSZ70 or HSZ80.
 
  HSZ50 is not supported for multipath operations.
 
  OpenVMS Alpha version V7.2 and later include multipath parallel SCSI
  and (with HSG80) multipath Fibre Channel support, and V7.2-1 (with ECOs)
  is the recommended release.
