Using EXCTGs with P9500
Cnt Ac-J Z can perform remote copy operations from more than one primary system to more than
one secondary system using EXCTGs. Both the primary and secondary systems can be a mix of
P9500 and XP24000/XP20000 Disk Array.
•
There is no limitation on the combination of P9500 and XP24000/XP20000 Disk Array
systems for either the primary or secondary systems. Any combination of system type is allowed.
•
There is no limitation on the journals that can be registered in the EXCTG when the supervisor
DKC is P9500 and the subordinate DKC is XP24000/XP20000 Disk Array. All journals in
P9500 and XP24000/XP20000 Disk Array can be specified as EXCTGs. This is shown in
Figure 15 (page 57) .
•
However, when the supervisor DKC is XP24000/XP20000 Disk Array and the subordinate
DKCs are P9500, journals of LDKCs other than LDKC00 cannot be registered in the EXCTGs.
This will be true even if the number of LDKCs is expanded in a future version. This is shown
in
Figure 15 (page 57) .
To clarify, please observe the following:
◦ The journal of LDKC00 of P9500 (subordinate DKC) can be registered in the EXCTG.
◦ The journal of LDKC01 of P9500 (subordinate DKC) cannot be registered in the EXCTG.
