Updating from a previous release
5. Perform a back up of the bootstrap, the client file indexes, and the resource database
on the NetWorker server:
savegrp -O group
To back up all client file indexes, specify a group that contain all the NetWorker clients
in the datazone.
If a group that contains all the clients does not exist, run multiple savegrp commands,
specifying a different group each time, until you back up all clients indexes.

Ensure the media pool associated with the group has appendable media available.
6. Record the latest bootstrap save set ID (ssid) including the file number, the record
number, and the associated volume label.
For example:
mminfo -B
In this example:
• The save set ID (ssid) is 4254377781.
• The file number is 0.
• The record number is 0.
• The label of the volume that contains the bootstrap save set is bootstrap_vol.001.
Preparing the storage node for Virtual Synthetic Full
Virtual Synthetic Full (VSF) requires a value in the volume location attribute for a Data
Domain device. NetWorker updates the volume location attribute during the device mount
operation. Before you update a storage node that uses Data Domain devices, unmount
each device. Once the update completes, mount each device.
Preparing for a Console server update
This section describes the steps you need to do on the Console server and Console clients
before you update the Console server.
Preparing the Console server
Before you update the Console server, perform a level Full backup of the Console server
database.

NetWorker 8.1 Administration
