Perform I/O
To perform I/O using dual controllers, the host should setup an MPIO policy. An MPIO policy
will keep I/O running and prevent connection failures that might happen when a single
controller fails. Please refer to the following topology and have all the connections ready
when configuring the system.
Ownership
When creating a RAID Group, it is assigned with a preferred owner. The default owner is
Controller 1 (Master). To change the RAID Group ownership:
1. Select Volume Configuration > RAID Groups.
2. Click the menu button (▼) next to the RAID Group name and select Change
Preferred Owner.
The ownership of the RAID Group will be switched to the other controller.
