IntraServer has implemented a port naming convention for SCSI devices on
PKWdriver to maximize the number of SCSI devices that can be used in a
cluster without being limited by the SCSI naming convention implemented
by OpenVMS. The driver can optionally be set to name the SCSI ports PKW
(default), PKX, PKY, or PKZ. This is done so that in cluster applications the
SCSI devices on one host system will not conflict with the SCSI devices on
another system with the same allocation class.
The installation procedure will inquire about the port letter required.
