12.6 Disabling BCC for a Cluster Resource
After enabling a resource for business continuity, it is possible to disable it. You might want to
disable BCC for a cluster resource in any of the following cases:
Š
You accidentally enabled the resource for business continuity.
Š You no longer want the cluster resource to be able to fail over between peer clusters.
Š
You plan to delete the cluster resource.
Š You plan to remove the peer cluster from the business continuity cluster. In this case, you must
disable BCC for each cluster resource before you disable BCC for the cluster.
IMPORTANT: If you disable Business Continuity Clustering for a cluster by using either iManager
or the
cluster disable
console command, the cluster resources in that cluster that have been
enabled for business continuity are automatically disabled for business continuity. If you re-enable
Business Continuity Clustering for the cluster, you must again re-enable each of its cluster resources
that you want to be enabled for business continuity.
This can be a time-consuming process if you have many cluster resources that are enabled for
business continuity. For this reason, you should use caution when disabling Business Continuity
Clustering for an entire cluster.
If BCC enabled resources need to be BCC disabled, remove the secondary peer clusters from the
resource’s assigned list, then disable BCC only from the primary cluster, either by using iManager or
command line. Do not BCC disable the same resource from multiple peer clusters.
To disable BCC for a cluster resource:
1
Start your Internet browser and enter the URL for iManager.
The URL is http://
server_ip_address /nps/iManager.html. Replace server_ip_address with the
IP address or DNS name of the server that has iManager and the Identity Manager
preconfigured templates for iManager installed.
2 Specify your username and password, specify the tree where you want to log in, then click
Login .
3 In Roles and Tasks , click Clusters , then click the Cluster Options link.
4 Specify the cluster name, or browse and select the Cluster object.
5 Select the desired cluster resource from the list of Cluster objects.
6 Click the Details link.
7 On the Preferred Nodes tab, remove the secondary peer clusters from the Assigned list, then
disable BCC for the resource on the primary peer cluster.
7a
Click the Preferred Nodes tab.
7b From the Assigned Nodes list, select the servers in the peer clusters you want to unassign
from the resource, then click the left-arrow button to move the selected servers to the
Unassigned Nodes list.
The primary peer cluster and the node where the resource is running cannot be moved
from the
Assigned list to the Unassigned list.
7c Click Apply to save node assignment changes.
