Quiesce servers or services for maintenance windows

To remove a server or service from the Load Balancer configuration for any reason (updates, upgrades, service, etc.), you can use the dscontrol(or cbrcontrol) manager quiesce command. You cannot use quiesce in the Site Selector component.

About this task

The quiesce subcommand allows existing connections to complete without being severed and disallows any new connections to a server or service. You can quiesce servers on a scheduled time to perform upgrades or general maintenance. The daily option specifies to quiesce the server at a time that you specify.
New feature New feature:
When you want to bring down a particular service on a server, like HTTP, you can now quiesce individual daemons. If you have added server1 to port 80 and port 22 of a cluster, for example, the usual quiesce command will stop forwarding traffic to server1 on port 80 and port 22. This new option allows you to stop traffic only on port 80 if you need to stop that particular service.newfeat
Tip: You can use similar steps for quiescing the server for the CBR component.
