Chapter 1 Maintaining Your WAAS System
Configuring the Central Manager Role
WAE(config)# central-manager role standby

WAE(config)# central-manager address cm-primary-address
Step 5 Enable the CMS service using the cms command:
WAE(config)# cms enable
Converting a Primary Central Manager to a Standby Central Manager
To convert a primary Central Manager to a standby Central Manager, follow these steps:
Step 1 Deregister the Central Manager using the cms command:
WAE# cms deregister
This command cleans up any previous association to any other Central Manager.
Step 2 Configure the Central Manager role as standby using the central-manager command:
WAE# configure
WAE(config)# central-manager role standby
Step 3 Configure the address of primary Central Manager using the central-manager command:
WAE(config)# central-manager address cm-primary-address
Step 4 Enable the CMS service using the cms command:
WAE(config)# cms enable
Converting a Standby Central Manager to a Primary Central Manager
If your primary WAAS Central Manager becomes inoperable, you can manually reconfigure one of your
warm standby Central Managers to be the primary Central Manager. Configure the new role by using the
global configuration central-manager role primary command as follows:
WAE# configure
WAE(config)# central-manager role primary
This command changes the role from standby to primary and restarts the management service to
recognize the change.
If the previous failed primary Central Manager again becomes available, you can recover it to again
become the primary Central Manager. For details, see the “Central Manager Failover and Recovery”
section on page 1-30.
If you switch a warm standby Central Manager to primary while your primary Central Manager is still
online and active, both Central Managers detect each other, automatically shut themselves down, and
disable management services. The Central Managers are switched to halted, which is automatically
saved in flash memory.
