Remove and replace the VTL head. Cable the new head to the same configuration as the old head. Make sure the new head has the same revision of firmware as the old head.

Connect and power on all disks.

From the serial console, bring up the server and set the IP address.

From the web browser, log in as admin.

If you have a saved configuration file, navigate to Configuration Management (Configuration Tasks > Miscellaneous > Configuration Management) and click Load Configuration. The screen updates; click Load user-saved configuration (from file);.browse to the location of the saved configuration file; click Apply.

If you do not have a saved configuration file, but do have the saved configuration data, create all libraries with same names, types, and order as the original. Using the example, the correct order is to create red followed by blue. Both libraries are of type NETAPP 7220.

Go to Configuration Tasks >RAID groups. In the Import RAID groups screen, the disks show the notation “labeled by another system”.

Select Import RAID groups.

Select all the disks that belong to this system and click Apply. Scanning of these disks starts.

Select the link To view the list of importing physical disks, click here.

View the status of the scanning. This screen is not automatically updated. Use your browser refresh button to update the screen. Scanning can take quite a long time (even hours, depending on the total size of all the disks).

When the scanning is complete (and the screen has been refreshed), a new message is displayed:

The RAID groups have been imported to this system, click here to assign the virtual tapes to libraries

Click this link.

Assign the virtual tapes to the appropriate virtual libraries. The GUI displays the library name in which the disk was originally used.

Add disks back to the hot spares pool.

The WWPNs of the ports changed; reassign all host-facing ports to the correct libraries.

As necessary, adjust the SAN zoning.

After you have completed this step, the system is operational.
