The unit (the differential-data management unit) that manages the differential data of a P-VOL and
an S-VOL can be specified in DIF UNIT in the Copy Group Attributes panel (for Cnt Ac-S Z/TCA).
Thus, the units vary for each of the following storage systems that are used:
•
HP XP12000/XP10000 disk array, HP XP24000/XP20000 disk array, or HP XP P9500 disk
array
•
HP XP7 storage
For HP XP7 storage, the unit for differential-data management is track only.
For details about DIF UNIT in the Copy Group Attributes panel (Cnt Ac-S Z/TCA), see the HP XP7
for Business Continuity Manager Reference Guide. For details about the difference management
unit, see the HP XP7 Continuous Access Synchronous for Mainframe User Guide.
Storage system identification
Differences in storage system identification in Business Continuity Manager are described in the
following sections.
Identification on the XP12000/XP10000 disk array
When the storage system is an XP12000/XP10000 disk array, Business Continuity Manager
considers the storage systems themselves to be storage systems and treats the physical DKC serial
numbers assigned to the individual storage systems as the storage systems serial numbers.
Figure 8 (page 49) shows the storage system serial numbers for XP12000/XP10000 disk arrays.
