Migrating Resources To Another Cluster - Novell BUSINESS CONTINUITY CLUSTERING 1.1 SP2 - ADMINISTRATION Administration Manual

You could also have Cluster One synchronize with Cluster Two, Cluster Two synchronize with
Cluster Three, and Cluster Three synchronize back to Cluster Two as illustrated in
Figure B-3
Cluster
Three
To change your BCC synchronization scenario:
1 In the Connections section of the Business Continuity Cluster Properties page, select one or
more peer clusters that you want a cluster to synchronize to, then click Edit.
In order for a cluster to appear in the list of possible peer clusters, that cluster must have the
following:
Business Continuity Clustering software installed.
Identity Manager installed.
BCC Identity Manager drivers configured and running.
Be enabled for business continuity.
B.7 Migrating Resources to Another Cluster
IMPORTANT: If you are migrating a pool to a cluster in another tree and you want to maintain that
pool's volume trustee assignments, you must migrate the pool to a server with an eDirectory replica.
The replica must be at least read-only and must contain all users. After migrating the pool to a server
with an eDirectory replica, enter the following console command on that server for each volume in
the pool:
NSS/ResetObjectIDStore=volumename
This command updates all volume trustee assignments and should be run at night, on a weekend, or
during a period of low network utilization. Trustee assignments become effective immediately, but
might take a few hours to display correctly in management utilities.
If you migrate the pool to a server in another tree without an eDirectory replica, you must, within 90
days, migrate that pool to a server with an eDirectory replica and then run the command for each
volume.
