Each cluster is assigned a Global Unique Identifier (GUID). This GUID is used by the system software to identify the cluster and does not appear in any of the System Administration Tool forms. Before a data-sharing voice cluster can be split into two distinct SDS clusters, you must reset the Global Unique Identifier (GUID) on one of the existing cluster elements. There are two options that you can use:
Reset the GUID of one of the cluster elements from an element outside the cluster.
Remove all the elements from one of the elements in the smaller cluster and create a new cluster.
NOTES:
Cluster A has elements MiVB1, MiVB2, MiVB3, and MiVB4.
Cluster A is to be split into two clusters; Cluster A with elements MIVB1 and MiVB2, and Cluster B with elements MiVB3 and MiVB4.
MiVB5 is an element that does not belong to any cluster, which is to be used to split Cluster A.
To split a data-sharing cluster:
Perform a full cluster-wide SDS share. Resolve any errors.
Log in to MiVB3.
Disable SDS sharing between MiVB3 and MiVB4. After disabled, re-enable it:
In the Network
Elements form
Reset the GUID for the new Cluster B:
Option 1 (recommended):
Reset the cluster GUID of MiVB3 from MiVB5.
From MiVB5, create a virtual cluster
by adding MiVB3 to the Cluster
Elements form
The system automatically configures MiVB3 with the hidden GUID
of the new Cluster B.
Disable SDS share with MIVB3.
From MIVB3, run the REMOVENE maintenance command to remove MiVB5 that was used to create the virtual cluster.
Option 2:
Remove all the elements from one of the element's in the smaller cluster and create a new cluster.
From MiVB3, run the REMOVENE maintenance command to remove MiVB1, MiVB2, and MIVB4. Remove the dependent data from ARS programming and the ICP/PBX Networking form.
Create a new Cluster B on MiVB3 and then add the member elements as required.
Proceed to step 6.
From MiVB3, enable SDS sharing and start sharing with MiVB4.
Update the new cluster name and Primary Node Identifier (PNI) as required.
