HP XP P9000 Business Copy User Guide (AV400-96573, July 2013)

Prerequisite information
• Pair status must be one of the following:
If you are splitting an existing pair, PAIR◦
◦ If you are creating and immediately splitting an L1 pair, SMPL status
◦ If you are creating and immediately splitting an L2 pair, the L1 pair must be split (PSUS
status)
• 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 Apply, both Copy Pace and Split
Type that you set during the last operation are the settings that are used for all split operations
(in the Preview list) when you click Apply.
• 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.

2. Change to Modify mode by clicking the icon.
3. In the tree, in the Pair Operations window, select the port or host group where the pairs or
