Solving Other Problems

Possible Cause
Cluster Administrator must be
used to take applications offline.
Some resources take time to go
offline.
IP address configuration may be
incorrect.
Groups may be configured to fail
back manually or the automatic
failback may be scheduled to
occur during a specific time
frame.
Action
Use Cluster Administrator to take
the application offline. Do not
close or exit an application from
the application interface.
Wait several minutes, then check
any dependencies that the
resource may have. Verify that
each can be taken offline.
1. IP addresses must be
different from every other IP
address resource and from
every other IP address on
the network.
2. The IP address must either
by reserved by the network
administrator or statically
assigned outside of a DHCP
scope.
1. If expecting an automatic
failback, verify that the
group is not set for a manual
failback.
2. If expecting an immediate
automatic failback, verify the
group is not configured to
fail back only during a
user-defined timeframe.
