Volume that canBeUsedtoCreatePairs
When you execute a Continuous Access Journal p air c onsisting of an H P XP24000 Disk Array volume
and
an HP XP12000 Disk Array volume, the HP XP24000 Disk Array volume must be a volume of
LDKC00. The CU:LDEV number of LDKC00 is between 00:00 an 3F:FF.
Note: 16,384 volumes of LDKC 0 0 (the CU:LDEV number is between 0 0:00 and 3 F :FF) can be used
for volume pairs in the current version.
Note: The steps to use data volume pairs in a system configuration where an HP XP24000 Disk Array
andanHPXP12000 Disk Arrayare connected arethe same as thesteps to usedatavolumepairs of
an HP
XP24000 Disk Array. For detailed information about the steps to use data volume pa irs, see
“Performing Continuous Access Journal Pair Operations” on page 125.
Connec
tion with an HP XP12000 Disk Array for a 3DC Remote Copy
Configuration
An HP XP24000 Disk Array can execute a remote copy in a 3DC cascading configuration or 3DC
multi-target configuration by combining Continuous Access Journal with Continuous Access Synchronous.
An
HP X
P24000 Disk Array and an HP XP12000 Disk Array can be connected in a 3DC cascading
config
uration or 3DC multi-target configuration. When you connect an HP XP24000 Disk Array and an
HP
XP
12000
Disk Array, there are no restrictions for the combination of the primary and secondary sites.
Note: For detailed information about the 3DC cascading configuration, see
“Continuous Access Synchronous (3DC Cascading Configuration)”onpage58.
For detailed information about the 3DC multi-target configuration, see
“Continuous Access Synchronous (3DC Multi-target Configuration)” on page 61.
