Multi-Host SCSI, Allocation Classes?

» close window

The Question is:

I want to set up a multi-host scsi bus using my Hsz80 and my 2 Aplha servers.
 According to the HSZ documentation I will need to change the SCSI ID on one to
 the KZ adapters to an ID other than the default of 7.  How is this
 accomplished?  I can't any inf
ormation on how to make the change.

The Answer is :

  In general, an SRM console environment variable is used, though
  different SCSI controllers can require different mechanisms.
  Use the console command SHOW PK* for details of the known SCSI
  port environment variables.
  Please contact your hardware services organization for further
  assistance with hardware- and storage-related questions, and
  for details of considerations, requirements, exceptions, SCSI
  canling and termination, and other details.
  If you configure a multi-host SCSI configuration, you must also
  look to use the same names on each host.  This normally requires
  the consistent use of a port allocation class, or an allocation
  class.  Failure to use the same name for the same device across
  all cluster hosts can lead to corruptions.
