Remove a Dead Peer From a Cluster (Permanently)
Use the following procedure if:
■
the VCS is dead and needs to be RMAd, or
■
the VCS cannot be accessed for some other reason
which clears up the removed VCS as well as its previous peers.
Note
: This procedure does not delete clustering configuration from the removed VCS. When removed, you must not
reconnect the out-of-service VCS without first deleting all of its peers and stopping FindMe and configuration replication

Ensure that the VCS to be removed from the cluster is not indicated as the primary VCS on Cisco TMS.

On the primary VCS:
1.
Go to System > Clustering.
2.
Delete the IP address of the VCS that has been removed.
3.
If the VCS being removed is not the last field in the list, move any other IP addresses up the list so that there are
no empty fields between entries.

If the primary VCS peer’s IP address has been moved up the list in the previous step, alter the Configuration

5.
Click Save.
On all the remaining subordinate VCS peers:
1.
Go to System > Clustering.
2.
Edit the Peer x IP address and Configuration master fields so that they are identical to those configured on the
primary VCS.

Click Save.

Repeat for all remaining subordinate VCS peers until they all have identical clustering configuration.
On other devices:
1.
If you have any other systems neighbored (or connected via a traversal zone) to this cluster of VCS peers, ensure
that their zone configuration for this cluster is updated to exclude the address of the removed peer.

2.
If you have any endpoints registering to the VCS that has now been removed, change the configuration of the
endpoint (or the configuration of the DNS server entry that points to the cluster peers) so that they register to one
of the remaining clustered VCS peers instead.

Removing an out-of-service VCS from a cluster is now complete.
Clear Configuration From This Peer
If you ever recover the peer that you removed, you must clear its configuration before you reconnect it to the network. The
easiest way to do this:
