Managing Novell Business Continuity Clustering; Migrating A Cluster Resource To Another Cluster - Novell BUSINESS CONTINUITY CLUSTERING 1.0 - ADMINISTRATION Manual

2.10 Managing Novell Business Continuity
Clustering
After you have installed, set up, and configured Novell Business Continuity Cluster software and
resources, some additional information can be useful to help you effectively manage your business
continuity cluster. This information consists of instructions for migrating resources from one cluster
to another, changing existing cluster peer credentials, and generating a business continuity report
that provides cluster configuration and status information.

2.10.1 Migrating a Cluster Resource to Another Cluster

There is no automatic failover and failback of cluster resources from one cluster to another as exists
within a cluster. You must manually migrate resources from one cluster to another cluster. If the
node where a resource is running fails, if the entire cluster fails, or if you just want to migrate the
resource to another cluster, you must manually start the cluster resource on another cluster in the
business continuity cluster. If the source cluster site fails, you will have to go to the destination
cluster site to migrate or bring up resources at that site. The resource will start on its preferred node
on the desination cluster.
To manually migrate cluster resources from one cluster to another:
1 Start Internet Explorer 5 or later 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 NetWare 6.5 server that has iManager and the DirXML
preconfigured templates for iManager installed.
2 Enter your username and password.
3 In the left column, click Cluster Administration, then click the Management link.
4 Specify a cluster name or browse and select one.
5 Click one of the cluster tabs.
This can be the cluster where the resource is currently located or a peer cluster for the resource.
6 Select one or more cluster resources, then click BCC Migrate.
7 Select the cluster where you want to migrate the selected resources, then click OK.
The resources will migrate to their preferred node on the destination cluster. If you select Any
Configured Peer as the destination cluster, the business continuity cluster software will choose
a destination cluster for you. The destination cluster that is chosen is the first cluster that is up
in the peer clusters list for this resource. All resources will be migrated to the cluster you select,
even if you select a cluster that is not currently a peer cluster for one or more of the selected
resources.
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. On the destination cluster, the resource changes from secondary to primary so that it can be
brought online.
A custom Perl script can be created for disk mapping on fibre channel SANs. The purpose of
this script is to make the LUNs in the SAN available to the destination cluster. A reverse script
can also be created for testing purposes so pool resources can be migrated back to the source
cluster.
