Use the vxrds activatebunker command to activate the Bunker RVG to take over the Primary role when the original Primary becomes unavailable.

After the Bunker RVG has been converted to a Primary, you can start replication to the Secondary host using the vxrds startrep command with the -b option to replay all the pending updates. When the updates have been replayed and the status of the Secondary is up-to-date, you can either perform a takeover to convert the Secondary to a Primary, or restore the original Primary, if it becomes available again.

Syntax for vxrds activatebunker command:

vxrds [-g <diskgroup>] activatebunker <local_rvg>

Example:

vxrds -g vvrdg -b activatebunker rvg
