Provisioning protection devices on Data Domain systems

1. To create the vDisk device pool and device group, type the following vDisk commands:
   vdisk pool create pool_name user username
   vdisk device-group create device_group_name pool pool_name

   The Data Domain Operating System Command Reference Guide provides details about the vDisk command and options.

2. For each VMAX3 source LUN that contains data, ensure that you have one backup device and one restore device. You might need additional restore devices for each source LUN if you also plan to restore data to different hosts.
3. To create the backup devices and restore devices with the same geometry as the VMAX source LUNs, and provision the devices accordingly, type the following vDisk command:
   vdisk device create [count count] heads head_count cylinders cylinder_count sectors-per-track sector_count pool pool_name device-group device_group_name

   NOTE The heads, cylinders, and sectors-per-track information that defines the device geometry must match the VMAX source LUNs.
4. Add the vDisk devices to the access group on the Data Domain system:
   1. Create a vDisk access group:
      scsitarget group create group_name service vdisk
   2. Add all the vDisk devices to the vdisk access group:
      vdisk group add group_name pool vdisk_pool_name device-group device_group_name
5. Verify that the VMAX3 DX ports and the Data Domain endpoint ports are zoned together.
6. View the list of VMAX3 initiators on the Data Domain system:
   scsitarget initiator show list
7. Add the VMAX3 initiators to the access group on the Data Domain system.
8. Add Symm initiators to the group:
   vdisk group add group_name initiator initiator_name
