Configuring CVM links for multi-subnet cluster networks


Configuring CVM links for multi-subnet cluster networks
Prev	Administering CVM	Next

This section provides information about using the CLI-based SFWConnectionManager utility to configure a CVM link for the nodes on multi-subnet cluster networks. To successfully create a CVM cluster, the participating cluster nodes must share a common cluster network. However, in case of a cross-subnet configuration, where you have nodes across different cluster networks, you need to use the SFWConnectionManager utility to create a CVM link to establish cluster and network communications across the nodes that forms a CVM cluster.

You must create or delete a CVM link using SFWConnectionManager before you run the SFW Configuration Wizard for Microsoft Failover Cluster (or its CLI equivalent ffconfigcli). If you make any changes to the existing CVM link of the CVM cluster using SFWConnectionManager after running the wizard (or ffconfigcli), then you need to unconfigure and re-configure CVM cluster for the changes to be reflected.

Using the SFWConnectionManager utility from CLI, you can perform the operations that are listed below:

Creating a CVM link: Run the following command to create a CVM link across cluster networks:

SFWConnectionManager -createlink <ClusterNetworkName 1>,<ClusterNetworkName 2>,...<ClusterNetworkName n>

This command creates a CVM link for the list of cluster networks provided.

Note:

If a cluster network's name has spaces, then it must be specified within double quotes.
Deleting a CVM link: Run the following command to delete an existing CVM link:

SFWConnectionManager -deletelink <CVMLinkName>

Note:

In place of <CVMLinkName>, use the -all option at the end of the command to delete all the CVM links.
Displaying CVM link information: Run the following command to display information about the CVM links and their cluster networks:

SFWConnectionManager -displaylinks
