Disaster Scenario
What Happens When
This Disaster Occurs
Recovery Process
A package (P1) is running on a
node (Node 1). Node 1
experiences a failure.
The package (P1) fails over
to another node (Node 2).
This node (Node 2) is
configured to take over the
package when it fails on
Node 1.
As the network and both the
mirrored disk sets are accessible
on Node 2, and were also
accessible when Node 1 failed, you
only need to restore Node 1. Then
you must enable the package to
run on Node 1 after it is repaired
by running the following
command:
# cmmodpkg -e P1 -n N1
