Exporting Dynamic Multi-Pathing (DMP) devices as virtual SCSI disks

DMP supports disks backed by DMP as virtual SCSI disks. Export the DMP device as a vSCSI disk to the VIO client.

To export a DMP device as a vSCSI disk

  1. Log into the VIO server partition.
  2. Use the following command to access the non-restricted root shell. All subsequent commands in this procedure must be invoked from the non-restricted shell. 
    $ oem_setup_env
  3. The following command displays the DMP devices on the VIO server:
    dmpvios1$ lsdev -t dmpdisk
    ibm_ds8000_0287 Available  Veritas DMP Device
ibm_ds8000_0288 Available  Veritas DMP Device
ibm_ds8000_0292 Available  Veritas DMP Device
ibm_ds8000_0293 Available  Veritas DMP Device
ibm_ds8000_029a Available  Veritas DMP Device
ibm_ds8000_02c1 Available  Veritas DMP Device
ibm_ds8000_0337 Available  Veritas DMP Device
  4. Assign the DMP device as a backing device. Exit from the non-restricted shell to run this command from the VIOS default shell. 
    dmpvios1$ exit
    $ mkvdev -vdev ibm_ds8000_0288 -vadapter vhost0
vtscsi3 Available
  5. Use the following command to display the configuration.
    $ lsmap -all

  6. For a dual-VIOS configuration, export the DMP device corresponding to the same SAN LUN on the second VIO Server in the configuration. To export the DMP device on the second VIO server, identify the DMP device corresponding to the SAN LUN as on the VIO Server1.

    • If the array supports the AVID attribute, the DMP device name is the same as the DMP device name on the VIO Server1.

    • Otherwise, use the UDID value of the DMP device on the VIO Server1 to correlate the DMP device name with same UDID on the VIO Server2.

      On VIO Server1:

      $ oem_setup_env
      dmpvios1$ lsattr -El ibm_ds8000_0288
      attribute value            description        user_settable 
dmpname   ibm_ds8x000_0288 DMP Device name   True 
pvid      none             Physical volume identifier True

0000288 
Unique device identifier   True

      On VIO Server2:

      $ oem_setup_env
      dmpvios2$ odmget -q "attribute = unique_id and 
value = 'IBM%5F2107%5F75MA641%5F6005076308FFC61A000000000
0000288'" CuAt
      CuAt: 

   name = "ibm_ds8000_0288"
   attribute = "unique_id"
   value = "IBM%5F2107%5F75MA641%5F6005076308FFC61A00
   00000000000288" 
   type = "R" 
   generic = "DU"
   rep = "s" 
   nls_index = 4
  7. Use the DMP device name identified in step 6 to assign the DMP device as a backing device. Exit from the non-restricted shell to run this command from the VIOS default shell. 
    dmpvios1$ exit
    $ mkvdev -vdev ibm_ds8000_0288 -vadapter vhost0

  8. Use the following command to display the configuration.
