Remote failover with local failover support using Service Guard
This is a combination of local failover and remote failover. For information on the local and remote
failovers, see “Configuring XOL HA for local failover without ServiceGuard” (page 62) and
“Configuring XOL HA for remote failover using Service Guard (SG)” (page 64). If the interface
cannot be activated on either the primary or the standby LAN card at a given time on the local
node, the SG package initiates the remote failover to the LAN card on the standby node in the
SG cluster.
NOTE: On any given LAN card, the combination of highly available and not highly available
XOL interfaces is not supported. Either all or none of the interfaces must be configured with HA
(for local or remote failover) on any given LAN card. This is because the same unique MAC address
is used by all XOL interfaces on the given LAN card.
To support remote failover with local failover, complete the following steps:
