Managing Metadata Controllers
This chapter shows how to add, switch, monitor, and upgrade
Xsan metadata controllers.
Every SAN volume you set up is managed by a metadata controller. To be sure that the
volume is available to clients even if the active controller becomes unresponsive, you
can set up standby controllers, one of which will assume control of the volume if the
primary controller fails.
This chapter shows you how to:
 Add a controller (page 122)
 Set controller failover priority (page 123)
 Switch to a standby controller (page 124)
 Find out which controller is hosting a volume (page 125)
 List the volumes hosted by a controller (page 127)
 Change a controller’s IP address (page 128)
 Upgrade controller software (page 129)
