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
XP24000/XP20000 Disk Arrays and XP12000/XP10000 Disk Arrays. The mixture of primary
storage systems and the mixture of secondary storage systems are described below.
NOTE:
For detailed information about the extended consistency groups, see
Primary and Secondary Storage Systems” (page 64)
.
•
Mixture of XP24000/XP20000 Disk Array and XP12000/XP10000 Disk Array primary
storage systems
There are no limitations on the combinations of XP24000/XP20000 Disk Array and
XP12000/XP10000 Disk Array primary storage systems. For details on connections between
the primary storage system and the secondary storage system, see the previous section.
•
Mixture of XP24000/XP20000 Disk Array and XP12000/XP10000 Disk Array secondary
storage systems
There are no limitations on the combinations of XP24000 Disk Array and XP12000/XP10000
Disk Array secondary storage systems. However, note that the specifications for the extended
consistency groups differ depending on whether the supervisor DKC is an XP24000/XP20000
Disk Array or an XP12000/XP10000 Disk Array. The specifications for the extended
consistency group when an XP12000/XP10000 Disk Array is connected is described below.
◦
When the supervisor DKC is an XP24000/XP20000 Disk Array and the subordinate
DKCs are XP12000/XP10000 Disk Arrays
There are no limitations for the use of extended consistency groups when the supervisor
DKC is an XP24000/XP20000 Disk Array and the subordinate DKCs are
XP12000/XP10000 Disk Arrays. All journal groups in an XP24000/XP2000 Disk Array
and an XP12000/XP10000 Disk Array can be specified as extended consistency groups.
Two examples of the configurations of a secondary EXCTG are described next.
