Setting Controller Failover Priority
When the primary metadata controller for a volume fails, Xsan uses the failover
priorities of the available standby controllers to decide which one to switch to.
Different volumes can be hosted by different controllers, and you can choose a failover
priority for each volume.
To set a metadata controller’s failover priority:
1
Open Xsan Admin, select Volumes in the SAN Assets list, and select a volume in the list.
2
Choose Edit Failover Priority from the Action (gear) pop-up menu.
3
Drag metadata controllers up or down in the list that appears.
The closer a controller is to the top of the list, the more likely it is that it will host the
volume.
4
Click OK.
