HP XP P9500 Storage - Manual (Page 106)

Prerequisite information
•
Pair status must be one of the following:
PAIR when splitting an existing pair ◦
◦ SMPL when creating and immediately splitting an L1 pair
◦ PSUS for the L1 pair, when creating and immediately splitting an L2 pair
•
For a split operation on an existing pair to complete faster, stop host access to the P-VOL.
•
If you are performing multiple split operations before clicking the Apply button, note that both
Copy Pace and Split Type that you set during the last operation are the settings that will be
used for all split operations (in the Preview list) when Apply is clicked.
•
The split operation may take longer than normal if system option mode 459 is ON and the
S-VOL is an external volume. The reason is because after differential data is copied to cache,
it must also be destaged to the external storage system, which takes more time.
