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

On the primary Expressway:
1.
Go to System > Clustering.
2.
Delete the IP address of the Expressway that has been removed.
3.
If the Expressway 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 Expressway peer’s IP address has been moved up the list in the previous step, alter the

On all the remaining subordinate Expressway peers:

Edit the Peer x IP address and Configuration master fields so that they are identical to those configured on the

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