• The Copy Pace drop-down list allows you to select the copy pace (from Slower, Medium, or
Faster) for all the pairs that you are splitting. By clicking Set, the same copy pace will be applied
to all the newly pairs that you are splitting.
Notes:
• When the Preview List already holds some Pairsplit settings, and you specify a different copy
pace for new pairs in the Pairsplit dialog box, the copy pace for the existing Pairsplit settings
displayed in the Preview List will be also changed. The latest copy pace specified in the
Pairsplit dialog box is in effect before the settings are reflected to the storage system.
• If you specify Slower, the pace of copying will be slow, but you can minimizes the impact
of Business Copy operations on storage system I/O performance. If you specify Faster, the
copy operation completes as quickly as possible, but it will cause a large impact on the
I/O operation.
• The Select MU drop-down list allows you to select the MU number for each pair being created
from: 0, 1, and 2 for L1 pairs, and 1 and 2 for L2 pairs.
Notes:
• You can select an MU number for a cascade pair. You cannot select the same MU number for
different cascade pairs of the same P-VOL (root or node volume).
• If you specify the MU number that is already used for XP Snapshot pair, or if you specify
MU number 0 for L2 pair, an error occurs.
• The Select Split Type drop-down list allows you to select the pairsplit type from Quick Split or
Steady Split. The following table shows read/write operations from the host servers to the volumes
during the pairsplit operation.
