After the resource information has been synchronized to the peer clusters, its preferred nodes settings in thelist in each peer are set to all nodes in the cluster by default. You can change the resource’s preferred nodes settings on peer clusters by specifying the preferred nodes within each of the peer clusters on the resource list.
Before you begin, ensure that you have assigned the preferred peer clusters for the resource. For information, see Section 8.5, Assigning Preferred Peer Clusters for the Resource.
For each BCC-enabled cluster resource, do the following for each peer cluster where you plan to fail over the cluster resource:
In iManager, click> , then click the cluster name.
Select the box next to the resource whose preferred node list you want to view or edit, then click thelink.
If this is a peer cluster where the resource is currently running, the cluster resource has a status of primary. On other peer clusters, the status is secondary.
From thelist, select the server you want the resource assigned to, then click the right-arrow button to move the selected server to the list.
Repeat this step for all servers you want assigned to the resource.
From thelist, select the servers you want to unassign from the resource, then click the left-arrow button to move the selected servers to the list.
The primary peer cluster and the node where the resource is running cannot be moved from thelist to the list.
Click the up-arrow and down-arrow buttons to change the preferred failover order of the servers assigned to the resource or volume.
Clickto save the node assignment changes.
The preferences apply immediately.
