Use the RemoveHANode command to permanently
remove a node from a high availability cluster.
About this task
You can use the steps described to remove a node from a
Dashboard Application Services Hub high availability cluster or
you can remove all nodes by running the
RemoveHANode command
on each node.
Procedure
- Stop and restart the server.
- In the JazzSM_WAS_Profile/bin directory,
for a server named server1,
run the following command:
- On Windows
- stopServer.bat server1
- On UNIX
- stopServer.sh server1
Note: You are prompted to provide an administrator
username and password.
- In the JazzSM_WAS_Profile/bin directory,
for a server named server1,
run the following command:
- On Windows
- startServer.bat server1
- On UNIX
- startServer.sh server1
- To remove the last node from a cluster, see step 3. For
any other node, remove the WebSphere Application Server data
source that was created when the node was joined to the cluster, stop
and restart the server, and on a separate node, do the following:
- At the command line, change to the following directory:
DASH_HOME/bin/
- Run the ListHANodes command
to list the current cluster nodes and their statuses:
- On Windows
- consolecli.bat ListHANodes --username console_admin_user_ID --password console_admin_password
- On UNIX
- consolecli.sh ListHANodes --username console_admin_user_ID --password console_admin_password
Where:
- console_adsmin_user_ID
- Specifies the console administrator user ID.
- console_admin_password
- Specifies the password associated with the administrator user
ID.
- Run the following command to remove
the specified node:
- On Windows
- consolecli.bat RemoveHANode --username console_admin_user_ID --password console_admin_password --nodename node_name
- On UNIX
- consolecli.sh RemoveHANode --username console_admin_user_ID --password console_admin_password --nodename node_name
Where:
- console_adsmin_user_ID
- Specifies the console administrator user ID.
- console_admin_password
- Specifies the password associated with the administrator user
ID.
- node_name
- Specifies the node that you want to remove. Refer to the node
names returned by the ListHANodes command in step 2.b to
ensure that you have the correct node name.
- For the last node in the cluster, run the RemoveHANode command
specifying its node name, as described in step 2.c, and then remove
the WebSphere Application Server data source that was
created when the node was joined to the cluster.
- In each case, stop and restart the server.
Results
The relevant node is removed from the high availability cluster
and is now a stand-alone console.
