Moving an Array between Systems

In Figure 38, exactly half of a RAID-10 array is being moved from its original
connections (adapter A and adapter B) to a new configuration where it is connected to
adapter C and adapter D.

Under these conditions:

v

The half of the array that is still connected to adapter A and adapter B is in the
Exposed state.

v

The half of the array that is connected to adapter C and adapter D is in the Offline
state. System 3 and system 4 generate SRN 48755.

You can solve this problem if you do one of the following:

v

Return the primary half of the array to its original adapters.

v

Move the secondary half of the array to the new adapters.
