Figure 39. Forcing Access on a RAID-10 Array
The Split Array Resolution flag has been set to Secondary to permit I/O operations to
be performed on the secondary half of the array. Only user actions can set this
condition. Separate write operations can be performed to each half of the array. If these
write operations are performed, however, the two halves of the array must not be
reconnected.
