It is important to remember that this is the case only when a complete site is lost. In the case of a
failedcontroller at one of the sites, a normal cluster failover occurs. Due to the operation of
SyncMirror, there is alsoadded protection from multidrive or complete shelf failures. When a
storage controller fails in an active-activeconfiguration, the partner detects the failure and
automatically (if enabled) performs a takeover of the dataservingresponsibilities from the failed
controller. Part of this process relies on the surviving controller beingable to read information from
the disks on the failed controller. If this quorum of disks is not available, thenautomatic takeover
won’t be performed. In a MetroCluster configuration, manually executing a single commandwill
allow a takeover to occur in spite of the lack of a quorum of disks. This “forced takeover” process
breaksthe mirrored relationships in order to bring the failed controller’s volumes on line.
forcetakeover -d is very dangerous. Not only can it cause data corruption, if not used carefully, it
can alsolead to a situation where both the node and its partner are operational (split brain). As
such, it should only beused as a means of last resort when the takeover and forcetakeover
commands are unsuccessful inachieving a takeover. The operator must ensure that the partner
node does not become operational at any timewhile a node is in a takeover mode initiated by the
use of this command. In conjunction with RAID mirroring, itcan allow recovery from a disaster
when the two nodes in the HA pair are located at two distant sites.
