NetWorker 19.7 Snapshot Management Integration Guide

Completing the VMAX system configuration

1. View the back-end ports (DX ports) on the VMAX array, and display the WWNs of the Data Domain devices zoned to the VMAX DX ports being viewed.
2. Display the LUNs that are visible for a specific Data Domain WWN.
3. List the disk groups that are available on the VMAX array.
4. Encapsulate all the Data Domain backup and restore devices to create the required eLUNs through the Federated Tiered Storage (FTS) software, and provision the restore LUNs to the restore host.

   The Solutions Enabler Symmetrix CLI Command Reference Guide provides details about the commands and options for FTS operations.

5. Mask all the restore devices to the recovery host.
   NOTE The application host can be the recovery host.
6. You can either create a VMAX storage group named NSRSNAPSG for the restore devices or you can create your own VMAX storage group. You must then specify NSM_SNAP_SG attribute in the recovery operation, with value of VMAX storage group name. This group name is case-insensitive:

   # symsg -sid SymmID create NsrSnapSG

   # symsg -sid SymmID -sg NsrSnapSG add dev <SymDevName>

7. Create the initial relationship between the source LUNs and the target backup eLUNs through a SnapVX link operation by using the symsnapvx commands.
   The latest Solutions Enabler Symmetrix CLI Command Reference Guide provides details about the symsnapvx commands and options. The following example shows the symsnapvx commands that are used to create an initial relationship between the source devices 28 and 29 and the target backup devices 9D and 9E:
   1. Create a snapshot name:

      # symsnapvx -sid 493 establish -devs 00028:0029 -name DD_SNAPVX

   2. Link the source LUNs and backup device:

      # symsnapvx -sid 493 link -devs 00028:00029 -lndevs 009D:009E -snapshot_name DD_SNAPVX -copy
      Execute Link operation for Device Range (y/[n])? y

   3. Wait for the copy operation to finish, and check the status:

      ledma114:/software/build147 # symsnapvx list -linked -dev 00028 -sid 493 -detail
