Volume Pair that Can Create Pairs
When you execute remote copy by connecting an XP24000/XP20000 Disk Array with an
XP12000/XP10000 Disk Array, only the volumes of LDKC00 are the volumes of the
XP24000/XP20000 Disk Array that can be used as the volume pair of Universal Replicator for
Mainframe. The CU:LDEV number of LDKC00 takes between 00:00 to 3F:FF.
NOTE:
•
16,384 volumes of LDKC00 (the CU:LDEV number is between 0000 to 3FFF) can be used as
volume pairs or remote command devices in the current version.
•
The steps to use data volume pairs in a system configuration where an XP24000/XP20000
Disk Array and an XP12000/XP10000 Disk Array are connected are the same as the steps
to use data volume pairs of an XP24000/XP20000 Disk Array. For detailed information about
the steps to use data volume pairs, see
“Performing Pair Operations” (page 185)
Connection with an XP12000/XP10000 Disk Array for a 3DC Remote Copy
Configuration
The XP24000/XP20000 Disk Array can execute remote copy in a 3DC cascading configuration
or a 3DC multi-target configuration by combining Universal Replicator for Mainframe with TrueCopy
for Mainframe. An XP24000/XP20000 Disk Array and an XP12000/XP10000 Disk Array can
be connected in a 3DC cascading configuration or a 3DC multi-target configuration. When you
connect an XP24000/XP20000 Disk Array and an XP12000/XP10000 Disk Array, there are no
limitations for the combination of the primary and secondary sites.
For detailed information about the 3DC cascading configuration, see
Synchronous (3DC Cascading Configuration)” (page 79)
). For detailed information about the 3DC
multi-target configuration, see
“TrueCopy for Mainframe Synchronous (3DC Multi-target
).
Connection with an XP12000/XP10000 Disk Array When Using Extended
Consistency Groups
Universal Replicator for Mainframe can perform remote copy operations from more than one
primary storage system to more than one secondary storage system using extended consistency
groups. Primary storage systems can be a mixture of XP24000/XP20000 Disk Arrays and
XP12000/XP10000 Disk Arrays. Secondary storage systems can also be a mixture of
