The Volume List located on the upper side of the Add Pair dialog box displays the following
information pertaining to the P-VOL and S-VOL used for adding a pair:

An LDEV number that ends with a pound or gate symbol (#) indicates that the LDEV is an

see the HP XP24000/XP20000 External Storage Software User's Guide.

different copy pace for new pairs in the Add Pair dialog box, the copy pace for the existing
Add Pair settings displayed in the Preview List will be also changed. The latest copy pace
specified in the Add Pair dialog box is always reflected to the storage system.
If you specify Slower, the pace of initial copying will be slow, but you can minimizes the
impact of SIz operations on storage system I/O performance. If you specify Faster, the initial
copy operation completes as quickly as possible, but it will cause a large impact on the I/O
operation.
