“Failback” on page 147

“Resuming backups following a failover/failback” on page 157.

Failback

For best results, run failback as a manual process, using the procedure outlined below.

▼Initiating failback

For the purposes of this description, the current, active node is VTLPLUSN2, the failover node for VTLPLUSN1, the failed/offline node.

1.Open a terminal window on the management host, and ssh to the IP address of the currently active node, VTLPLUSN2:

[VTL_Plus]vtladmin# ssh vtladmin@nnn.nnn.nnn.nny

Connecting to nnn.nnn.nnn.nny ...

Password:

where nnn.nnn.nnn.nny is the management or “server” IP address of VTLPLUSN2, the node that took over for the failed server node, VTLPLUSN1 and vtladmin is the VTL administrator account user ID.

2. Make sure that you are logged in to the actual, active node:

[VTL_Plus]vtladmin# uname -a

SunOS VTLPLUSN2 n.nn Generic_nnnnnn-nni86pc i386 i86pc
