Configuring High Availability
Remove Cluster Master
After you have removed the participant from the cluster, you must disable HA
on the master. When removing the master from the cluster, you can choose to
have the master retain the cluster’s IP settings, or you can clear the cluster IP
addresses from the module. If you clear the cluster IP settings, you must
reconfigure IP addresses on the master’s TMS VLANs.
To retain the cluster IP addresses on the master, use the Web browser
interface. See “Use the Web Browser Interface to Remove the Master” on
page 8-19.
To remove the cluster IP addresses from the master, use the CLI. See “Use the
CLI to Remove the Master” on page 8-19.
Use the Web Browser Interface to Remove the Master. When using the
Web browser interface to remove the master from the cluster, the master will
retain all of the cluster IP addresses.
To remove an HA cluster master, follow these steps:
1. In the Web browser interface, select System > Settings > High Availability.
2. Under Cluster Scheme, select None.
3. Click Apply my changes.
4. Click Save.
5. Click OK. (You may be warned that the cluster scheme has been changed
and reminded to make this change on all members of the cluster.)
6. Click OK.
7. Click System > Maintenance and click the Reboot tab. Click the Reboot
button and click Save & reboot at the prompt.
When the module reboots, it will no longer be part of a cluster. It will have all
of the IP addresses that were assigned to the cluster.
Use the CLI to Remove the Master. When using the CLI to remove the
master from the cluster, you can opt to delete the cluster IP settings from the
module. If you choose this option, you will need to reconfigure all of the TMS
VLAN interface IP addresses on the master.
1. Initiate a console session with the master’s host switch.
