Enabling maintenance mode
Maintenance mode is typically used when you need to upgrade or take out of service a VCS peer that is part
of a cluster. It allows the other cluster peers to continue to operate normally while the peer that is in
maintenance mode is upgraded or serviced.
Putting a peer into maintenance mode provides a controlled method of stopping any further registrations or
calls from being managed by that peer:
Standard VCS sessions:
n
New calls and registrations will be handled by another peer in the cluster.
l
Existing registrations are allowed to expire and they then should re-register to another peer (see VCS
l
Cluster Creation and Maintenance Deployment Guide for more information about endpoint configuration
and setting up DNS SRV records).
Existing calls will continue until the call is terminated. If necessary, you can manually remove any calls
l
on this peer that do not clear automatically by going to
the calls you want to terminate and clicking Disconnect (note that SIP calls may not disconnect
immediately).
Unified CM mobile and remote access sessions:
n
Any existing calls passing through that VCS will be dropped.
l
Jabber clients will failover automatically and re-register through another peer in the cluster.
l
Clients running TC software will not failover automatically will have to be restarted.
l
To maintain capacity, we recommend that you only enable maintenance mode on one peer at a time.
To enable maintenance mode:
1. Log in the relevant peer.
2. Go to the
Maintenance mode
3. Set Maintenance mode to On.
4. Click Save and click OK on the confirmation dialog.
Note that:
An alarm is raised while the peer is in maintenance mode.
n
You can monitor the Resource usage page
n
registrations and calls are currently being handled by that peer.
Maintenance mode is automatically disabled if the peer is restarted.
