Tru64 needs and entry entered into the ddr.dbase file:
backup the /etc/ddr.dbase first.  Here's the entry needed, put it under the DISKS section:

    #
    Type = disk
    Stype = 2
    Name = "DGC"
    #
    PARAMETERS:
      #
      TypeSubClass = hard_disk, raid
      BlockSize = 512
      BadBlockRecovery = disabled
      DynamicGeometry = true
      DisperseQueue = false
      TagQueueDepth = 32
      PwrMgmt_Capable = false
      LongTimeoutRetry = enabled
      ReadyTimeSeconds = 90
      InquiryLength = 120
      RequestSenseLength = 120
      #

      #
      AttributeName = "DSBLflags"
      Length = 4
      ubyte[0] = 25
      #
    ATTRIBUTE:
      #
      # Disable Start Unit with every VPD Inquiry
      #
      AttributeName = "VPDinfo"
      Length = 16
      ubyte[6] = 4
      #

      #
      # Report UDID value in hwmgr -view devices
      #
      AttributeName = "rpt_chgbl_dev_ident"
      Length = 4
 
After this is entered, you need to recompile the ddr.db file using the ddr_config -c command.  You'll need to contact you SAN guy to create the LUN and setup security on the SAN side of things.  Once that's done, you should be able to see the LUN after you scan: hwmgr -scan scsi   then view the devices: hwmgr -show scsi
