2 If you are powering on MDC Node 1, and MDC Node 2 is currently
operating as the primary, perform a system failover after MDC Node
1 comes back online (see Initiating a Graceful System
Failover on
page 70), if desired, to set MDC Node 1 to act as the primary node.
3 On each LAN client, mount the file systems on clients.
