Migrating Cluster Resources Between Clusters - Novell BUSINESS CONTINUITY CLUSTERING 1.2.1 - ADMINISTRATION Administration Manual

Migrating a pool resource to another cluster causes the following to happen:
1. If the source cluster can be contacted, the state of the resource is changed to offline.
2. The resource changes from primary to secondary on the source cluster.
3. Any storage management unload script that is associated with the pool resource is run.
4. The
cluster scan for new devices
cluster is aware of LUNs that are no longer available.
5. On the destination peer cluster, the resource changes from secondary to primary so that it can
be brought online.
6. Any storage management load script that is associated with the pool resource is run.
If a error is returned from the BCC load script, the resource is not brought online and remains
in the offline, not comatose, state.
7. The
cluster scan for new devices
so that the cluster is aware of LUNs that are now available.
8. Resources are brought online and load on the most preferred node in the cluster (that is, on the
first node in the preferred node list).
TIP: You can use the
preferred node on the destination cluster.
9. Resources appear as running and primary on the cluster where you have migrated them.

11.1.2 Migrating Cluster Resources between Clusters

WARNING: Do not migrate resources for a test failover if the storage connection between the
source and destination cluster is down. Possible disk problems and data corruption can occur if the
down connection comes up and causes a divergence in data. This warning does not apply if
resources are migrated during an actual cluster site failure.
To manually migrate cluster resources from one cluster to another:
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 BCC Manager link.
4 Specify a cluster name, or browse and select the Cluster object of the cluster you want to
manage the BCC from.
5 Select one or more cluster resources, then click BCC Migrate.
The cluster you chose in
Current Cluster is associated with the first table on the BCC Migrate page. It tells you what
cluster you selected to manage the BCC from so that you understand the point of view that the
status information is provided in the first table. For example, if the resource is assigned to a
node in the cluster you are managing from, the cluster resource status is the same as if you were
