HP Serviceguard Quorum Server Version A.03.00 Release Notes
Replacing a Failed Quorum Server System
Chapter 1 29
7. To check that the Quorum Server has been correctly configured and
to verify the connectivity of a node to the Quorum Server, you can
execute the following command from your cluster nodes as follows:
cmquerycl -q <QS_Host> -n <Node1> -n <Node2> ...
or (if you are using more than one subnet; see “Using Alternate
Subnets” on page 19):
cmquerycl -q <QS_Host> <QS_Addr> -n <Node1> -n <Node2> ...
The command will output an error message if the specified nodes
cannot communicate with the Quorum Server.
While the old Quorum Server is down and the new one is being set up,
these things can happen:
• These three commands will not work: cmquerycl -q, cmapplyconf
-C, and cmcheckconf -C.
• If there is a node or network failure that creates a 50-50 membership
split, the Quorum Server will not be available as a tie-breaker, and
the cluster will fail.
CAUTION Make sure that the old system does not re-join the network with its old
IP address(es).
