Changing the Cluster Type

This section presents procedures for converting cluster members from one cluster type (High Availability or VSLS) to the other. Changing the cluster mode involves the use of the vsx_util convert_cluster command.

Included Topics Converting from VSLS to High Availability Converting from High Availability to VSLS Sample Command Output

Converting from VSLS to High Availability

Do these procedures to convert a cluster from VSLS to High Availability:

1. Redistributing all active Virtual Systems to one member
2. Disabling VSLS options
3. Converting the cluster to High Availability

Redistributing Active Virtual Systems to One Member

To redistribute all active Virtual Systems to one member:

1. Close SmartDashboard.
2. From the CLI, enter Expert mode.
3. Run vsx_util vsls
4. Enter the administrator user name and password.
5. Enter the IP address for the Security Management Server or Domain Management Server.
6. Select the VSX cluster name.
7. From the Load Sharing menu, enter 3. Set all VSs active on one member.
8. Enter the number of the cluster member that is hosting the active members.
9. Enter Y to save and apply the configuration.
10. Exit the Load Sharing menu.

When the convert_cluster command finishes, there should be only one active member on which all Virtual Systems are in the active state, and one standby member on which all Virtual Devices are in the standby state. Any additional members should be in standby mode and their Virtual Devices in the down state.

Disabling VSLS Options

To convert existing cluster members to the VSX Gateway High Availability mode:

1. On each member, execute the cpconfig command and do the following:
   1. Disable the Per Virtual System State for each member.
   2. Disable ClusterXL for Bridge Active/Standby for each member.
2. Re-initialize the members using the cpstop and cpstart commands.

Converting the Cluster

To convert the cluster to HA:

1. Run vsx_util convert_cluster
2. Enter the IP address for the Security Management Server or Domain Management Server.
3. Enter the administrator user name and password.
4. From the Load Sharing menu, enter 3. Set all VSs active on one member.
5. Enter or select the VSX cluster name.
6. Enter HA.
7. Reboot all members.

Converting from High Availability to VSLS

To convert an existing High Availability cluster to VSLS:

1. Close SmartDashboard.
2. On each member:
   1. Run cpconfig
   2. Enable the Per Virtual System State.
   3. Enable ClusterXL for Bridge Active/Standby.
3. Restart the members: cpstop and cpstart
4. On the management server, enter Expert mode.
5. Run: vsx_util convert_cluster
6. Enter the Security Management Server or Multi-Domain Security Management Domain Management Server IP address.
7. Enter the administrator user name and password.
8. Enter the VSX cluster name.
9. Enter: LS
10. At the "Proceed with conversion?" prompt, enter: y
11. Select an option to distribute Virtual Systems among members:
    1. Distribute all Virtual Systems equally.
    2. Set all Virtual Systems as Active on the same member.
12. Reboot the members.

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.
