9.10 Changing the IP Address of a Cluster
Resource
You can change the IP address of a cluster resource by using the Cluster Properties page of the
Clusters plug-in in iManager. Make sure to offline the cluster resource before attempting to change
its IP address. When you online the cluster resource, the load script is updated with the new IP
address.
9.11 Deleting Cluster Resources
Make sure to offline the cluster resource before attempting to delete either the cluster resource or the
clustered pool.
WARNING:
If you attempt to delete a cluster resource without first offlining it, deletion errors
occur, and the data associated with the clustered pool is not recoverable.
To delete a resource and create a new one with the same name, you must wait to create the new one
until eDirectory synchronizes all of the objects in the tree related to the deleted resource.
Section 9.11.1, “Deleting a Cluster Resource on a Master Node,” on page 128
Section 9.11.2, “Deleting a Cluster Resource on a Non-Master Node,” on page 129
9.11.1 Deleting a Cluster Resource on a Master Node
We strongly recommend that when you need to delete a cluster resource, that you do so only from
the master node in the cluster. If the resource cannot be migrated to the master node, follow the
procedure in
Section 9.11.2, “Deleting a Cluster Resource on a Non-Master Node,” on page 129
.
You might want to delete the shared storage area if you no longer need the data.
WARNING:
Deleting a pool or Linux POSIX volume destroys all data on it.
1
If the resource is on a non-master node in the cluster, migrate it to the master node.
2
If the cluster resource is online, offline it before continuing by using one of the following
methods:
Enter the following at the terminal console prompt as the
root
user:
cluster offline
resource
In iManager, go to
Clusters > Cluster Manager
, specify the cluster you want to manage,
select the cluster resource, then click
Offline
.
3
Delete the resource on the master node by using the appropriate storage management tool:
For shared NSS pools and volumes, use NSSMU or the Storage plug-in to iManager.
Deleting the pool automatically deletes the volumes on it.
For shared Linux POSIX volumes, use evmsgui.
