Node 1 in a clustered pair detects that it has lost connectivity to one of its disk shelves. Node 1 is
still up, but it cannot see one of its disk shelves. However, the partner node, Node 2, can see all of
the Node 1’s disk shelves. Which feature will cause Node 2 to monitor this error condition for a
period of three minutes by default, and then forcibly take over Node 1 if the error condition
persists?
A.
Auto enable of giveback
B.
Negotiated Fail Over
C.
Takeover on panic
D.
Cf.quickloop.enable

Negotiated failover is a general facility which supports negotiated failover on the basis of
decisionsmade by various modules.
cf.takeover.on_disk_shelf_miscompare
This option allows negotiated takeover to be enabledwhen the cluster nodes detect a mismatch in
disk shelfcount. By default, this option is set to off.
This option is available only when cluster is licensedand changing the value on one filer
automaticallychanges the value on the partner filer.
