manually start the cluster resource on another cluster in the business continuity cluster. If the source
cluster site fails, you must go to the destination cluster site to manually migrate or bring up
resources at that site. Each resource starts on its preferred node on the destination cluster.
TIP:
You can use the
cluster migrate
command to start resources on nodes other than the
preferred node on the destination cluster.
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 the left column, click
Clusters
, then click the
BCC Manager
link.
4
Specify a cluster name, or browse and select one.
5
Select one or more cluster resources, then click
BCC Migrate
.
6
Select the cluster where you want to migrate the selected resources, then click
OK
.
The resources migrate to their preferred node on the destination cluster. If you select
Any
Configured Peer
as the destination cluster, the Business Continuity Clustering software
chooses 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.
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 SAN script that is associated with the pool resource is run.
4. 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
is also created for testing purposes so pool resources can be migrated back to the source cluster.
5. The
cluster scan for new devices
command is executed on the destination cluster so that
the cluster is aware of LUNs that are now available.
6. Resources are brought online and load on the their most preferred node in the cluster.
7. Resources appear as running and primary on the cluster where you have migrated them.
WARNING:
Do not migrate resources for a test failover if the peer (LAN) connection between the
source and destination cluster is down. Possible disk problems and data corruption could occur. This
warning does not apply if resources are migrated during an actual cluster site failure.
