Configuring High Availability
Disabling a Cluster
When disabling an HA cluster, you must complete the following tasks in the
order listed:
■ Remove the cluster participant (See “Remove Cluster Participant” on
page 8-17.)
■ Remove the cluster master (See “Remove Cluster Master” on page 8-19.)
Remove Cluster Participant
When disabling the cluster, you should always remove the participant from
the cluster first. Because the participant does not have any IP addresses while
it is part of the cluster, you must use the participant’s CLI to remove it.
To remove an HA cluster participant, follow these steps:
1. Initiate a console session with the participant's host switch.
2. From the switch CLI, access the participant’s Product OS context:
You should see a prompt similar to the following:
hostswitch(tms-module-E)#
3. Ensure this module is the cluster participant:
Syntax: services <slot ID> < <product index> | name <product name> >
Moves you to an OS context on the module.
Replace <slot ID> with the letter for the chassis slot in
which the module is installed.
Replace <product index> with the product index assigned
tot he TMS zl Module. See “Understanding Index Num-
bers” on page 2-18 of Chapter 2: “Initial Setup in Routing
Mode.”
Replace <product name> with tms-module. The TMS zl Mod-
ule’s Product OS context is always assigned the product
name tms-module.
Syntax: show high-availability
Displays the module’s high-availability settings.
