An LDEV number that ends with a pound or gate symbol (#) indicates that the LDEV is an
external volume (for example, 00:00:01#). An LDEV number that ends with a letter X
indicates that the LDEV is a virtual volume used by XP Thin Provisioning (for example,
00:00:01X). For details regarding the external volumes, see the HP StorageWorks
XP24000/XP20000 External Storage Software User Guide. For information about XP
Thin Provisioning, see the HP StorageWorks XP24000/XP20000 Thin Provisioning

Performing Only Pair Splitting
To split one or more existing XP Business Copy pairs:
CAUTION: The P-VOL and S-VOL are synchronized only when the pair status changes from
COPY(SP) or PSUS(SP) to PSUS. Due to the XP Business Copy asynchronous update copy operations,
this status transition can take several minutes.
If you want the S-VOLs you are intending to split to be identical to the P-VOLs, stop all write
operations to the P-VOLs before splitting the pairs. This ensures that there are no updates to the
P-VOLs while the pairsplit operations are synchronizing the S-VOLs to the P-VOLs.
1. Go to the Pair Operation window, and select the desired port or host group in the Tree to
filter the volumes displayed in the Volume List.
2. Select the pairs you want to split, right-click the selected pairs to display the menu, and then
select the Pairsplit command to open the Pairsplit dialog box.
You cannot split a suspended (PSUE) pair.
