  Third-party SAN storage? (Fibre Channel) 
 The Question is:
 
Fibrechannel in an open SAN
 
I know that the only storage supported in a compaq SAN is the compaq storage.
 But I have done some testings trying to connect to a HDS storage device and
 would appriciate if you could answer to the problem that I see below??
 
Current config of HDS 7700E and OpenVMS test environment
 
AlphaServer 1200 5/533 4 MB			Alphaserver 1000A 5/500
533 MHz
2 CPU:s					1 CPU
1 GB memory					512 MB memory
1 disk 4 GB					1 disk 9 GB
1 KZPBA-CB UWD SCSI			1 KZPBA-CB UWD SCSI
1 KGPSA-BC HBA optic				1 KGPSA-BC HBA optic
 
 
Both servers running OpenVMS 7.2-1 with patches VMS721_PCSI, VMS721_UPDATE ,
VMS721_FIBRECHAN_V0300
 
I can see my LUN's at the P00&gt;&gt;&gt; with the wwidmgr command, but when I boot the
 OpenVMS system I can't see any dga disks. This I think is due to the unique
 unit ID's that are setup in the HSG and can't be setup in the 7700E.
 
But I would appriciate if that could be confirmed and I would also like to know
 if there are
any plans for making the VMS environment to be included in an open SAN
 configuration.

All this information is at the boot level but when I boot up the OpenVMS I
 can't see any $1$DGA disks.
 
Many Thanks and Best Regards

 The Answer is:
 
  The OpenVMS Wizard is not in a position to assist with the integration
  and testing of third-party devices.  In the experience of the OpenVMS
  Wizard, this task can range from simple and quick to extremely difficult
  and time-consuming, with resolutions ranging from the simple (no changes
  required) to massive (and potentially incompatible) changes to the device
  itself and/or to OpenVMS.  The effort that is involved in simply verifying
  correct operation across a variety of configurations -- a testing effort
  that is involved in establishing a particular device as being supported
  -- is non-trivial.
 
  In this case, there are clearly at least some changes that will be
  required to the Fibre Channel device or to the local Fibre Channel
  device configuration, or to OpenVMS itself.  While the world-wide
  identifier (WWID) is globally unique, OpenVMS also requires that the
  Fibre Channel subsystem (usually the HSG) provide it with a user-assigned
  unit ID value for the device, with the value typically established and
  maintained via the HSG console and the wwidmgr console tool.  This value
  provides the OpenVMS unit number.
 
  For information on OpenVMS Fibre Channel configurations and associated
  tools, please see:
 
    http://www.openvms.compaq.com/openvms/fibre/
 
  If you wish to work with Compaq Services and/or with OpenVMS Engineering
  to test and to verify the compatibility of your particular devices with
  OpenVMS, that work can (likely) be formally arranged.
