Can set Cross Call function ON/OFF.
y Cross Call ON state
This can be set when two controllers exist. In this state, all the logical disks can be accessed from the two
controllers. The Auto Assignment function is disabled.
y Cross Call OFF state
Refers to the disk array’s initial state. The logical disk can be accessed only from the controller which has the
Ownership.
In this case, it becomes possible to set the Auto Assignment function.
y Auto Assignment function
Enabled when two controllers are available. The purpose of this function is automatically switching to the access
to another controller when the primary controller goes down.
When the Cross Call is set to OFF, there may exist logical disks which can no longer be accessible from OS,
according to the Ownership and the connected controller. In this case, please change the Ownership.
