To create EMC disk groups for VSS differential snapshots that use EMC TimeFinder Snap

1. Create a disk group to contain any number of primary and secondary disks.

   symdg create nbfim_test

   Creates a disk group named nbfim_test.

2. Add primary disks to the disk group.

   symld -g nbfim_test add dev 02A

   Adds a primary disk 02A to disk group nbfim_test.

3. Add a VDEV disk to the disk group.

   symld -g nbfim_test add dev 08C -vdev

   Adds the VDEV disk 08C to the nbfim_test disk group.

   When these commands are successfully entered, NetBackup can make snapshot backups with primary device 02A and its target VDEV 08C.
