Configuring LUNs for use with VERITAS DMP

If you are using the VERITAS Volume Manager with the Dynamic Multi-Pathing (DMP) for multipathing support on an Oracle host, you must use these instructions to configure the LUNs.

You can use the following steps for all HBAs that are used with the VERITAS Volume Manager with DMP:

  1. Issue the format command to check for disks.
    1. If you see disks, proceed to the next step.
    2. If you do not see disks, verify the configuration of your HBAs and clustered-system configuration and try again.
    Note: You might see a "mode sense error" that is listed for each disk when you run format for the first time. This result is normal, and does not occur after the disks are labeled.
  2. Label each device by using the Solaris operating system format command.
  3. Use the vxdiskadm utility to initialize the disks by completing these steps:
    1. Start the vxdiskadm utility.
    2. From the menu, select 21 (Get the newly connected/zoned disks in VxVM view).
    3. Press c to continue and then press Enter. Wait for the command to complete.
    4. From the menu, select 1 (Add or initialize one or more disks) and initialize each disk.
  4. Run the vxdisk list command to see the devices. You can now use the devices to create VERITAS Volume Manager devices when added to a volume group.
