This topic will guide you through the required steps to manually clean up a cluster
domain. Uninstalling Db2® Enterprise Server
Edition with IBM®
Db2
pureScale® Feature will normally
handle the removal of the cluster manager. Follow these steps if an unexpected error occurs and a
manual cleanup is required.
About this task
The db2idrop -g command should automatically remove the cluster. The
following manual steps are needed only when problems occur.
Procedure
- List all of the existing peer domains by running the
lsrpdomain command.
The output of this command should be similar
to the following one:
Name OpState RSCTActiveVersion MixedVersions TSPort GSPort
db2domain Online 2.5.3.5 No 12347 12348
If
nothing is listed, there is no active peer domain. Only one cluster can be active (online) at any
given time, and any operations (stopping, removing, or adding a node) will only affect this online
domain.
- List all of the nodes in this active peer domain by running the db2cluster -cm
-list -host -state command.
The output of this command should be similar to the following
output:
HOSTNAME STATE
----------- ------
coralpib135 ONLINE
coralpib136 ONLINE
- Remove the entire peer domain, including all nodes. The peer domain must be online for
the following command to be successful. Run the db2cluster -cm -delete -domain
db2domain command.
The output of this command should be similar to the following
output:
Deleting the domain db2domain from the cluster ...
Deleting the domain db2domain from the cluster was successful.
- To confirm that the peer domain has been removed appropriately, run the
db2cluster -cm -list -domain command.
