This section presents procedures for converting VSX Cluster between High Availability and VSLS.
Changing the VSX Cluster mode involves the use of the vsx_util convert_cluster
command on the Management Server.
Do these procedures to convert a VSX Cluster from VSLS to High Availability:
To redistribute all active Virtual Systems to one VSX Cluster Member:
vsx_util vsls
When the vsx_util convert_cluster
command finishes, there should be only one Active VSX Cluster Member, on which all Virtual Systems are in the Active state, and one Standby VSX Cluster Member, on which all Virtual Systems are in the Standby state. Any additional VSX Cluster Members should be in Standby state, and their Virtual Systems in the Down state.
To convert existing VSX Cluster Members to the VSX High Availability mode:
Perform these steps on each VSX Cluster Member:
cpconfig
cpstop ; cpstart
To convert the VSX Cluster to High Availability:
vsx_util convert_cluster
HA
vsx state -v
cphaprob state
To convert an existing VSX Cluster from High Availability to VSLS:
cpconfig
cpstop ; cpstart
vsx_util convert_cluster
LS
Proceed with conversion?
prompt, enter: y
vsx state -v
cphaprob state
Note - You cannot convert a VSX Cluster to the VSLS mode, if it contains Virtual Systems in the Active/Active Bridge mode or Virtual Routers.
The following screen printout shows an example of the output from the vsx_util convert_cluster
command.
This sample output is for versions R77.10 and higher.

All modules must be in the 'Per VS State' mode to conclude this operation When converting a cluster, there are two options for distributing the 1. Distribute all Virtual Systems so that each cluster member is equally loaded. 2. Set all Virtual Systems as Active on the same cluster member.
After converting the cluster, the command vsx_util redistribute_vsls may Enter distribution option (1-2) [1]: 1
