
Recreates the original array

Retains data from Logical Drive 1

Removes Logical Drive 3, along with all data
To keep the modifications made to Logical Drive 1 after the SPLITMIRROR:
Action= Reconfigure
Method= Custom Controller= SLOT 6
Array= A
SplitMirror= Remirror
After the command executes, Array C is removed and physical drive 2 (PDrive2) is now a mirror of PDrive1,
with the original contents of PDrive2 lost.
Example 2: SplitMirror = Rollback
This form of the command does the following:

Recreates the original array

Retains data from Logical Drive 3 (that is, the original data at the time of the split)

Removes Logical Drive 1, along with all data
To return to the original configuration at the time of the SPLITMIRROR:
Action= Reconfigure
Method= Custom Controller= SLOT 6
Array= A
SplitMirror= Rollback
After the command executes, physical drive 1 (PDrive1) becomes a mirror of PDrive2 (the original data at the
time of the split), with the modifications to PDrive1 lost.
If this example is attempted while the system in online (that is, booted from Logical Drive 1), a blue- screen or
kernel panic will likely result. Perform this command offline and ensure the volumes involved in the join are
not mounted or otherwise used by the Operating System.
Example 3: SplitMirror = ActivateBackup

Exposes the hidden logical drive to the operating system

Retains the data from Logical Drive 1

Retains the data from Logical Drive 3
To keep the modifications made to Logical Drive 1 and also access the original logical volume data at the
time of the SPLIT, enter the following:
Action= Reconfigure
Method= Custom
Controller= SLOT 6
Array= A
SplitMirror= ActivateBackup
After the command executes, Logical Volume 3 is exposed to the Operating System.
There might be implications with the operating system with respect to the volume name, unique IDs, and so
forth, which may require manual intervention by the System Administrator.
