Continuous Access Journal Z

You can share Cnt Ac-J Z volumes with BC Z volumes.

• You can share BC Z P-VOLs with Cnt Ac-J Z P-VOLs and S-VOLs.

• You cannot share BC Z S-VOLs with Cnt Ac-J Z S-VOLs.

• You cannot share BC Z pair volumes with Cnt Ac-J Z journal volumes.

• You cannot perform the Quick Restore operation on the BC Z pair when the Cnt Ac-J Z pair

is suspended.

• You can use PPRC to query pair status for BC Z and Cnt Ac-J Z shared volumes. The storage

system reports the BC Z status, but does not report the Cnt Ac-J Z status. Use BCM to obtain

Cnt Ac-J Z’s pair status.

• You can share BC volumes with Cnt Ac-J volumes in a 3 Cnt Ac-J data center configuration.

For more information, see “Sharing volumes in 3-Cnt Ac-J Z data center configurations”

(page 26).

• You can share the BC Z P-VOL with Cnt Ac-J Z and Cnt Ac-S Z volumes in a 3 Cnt Ac-J Z/Cnt

Ac-S Z data center configuration. For more information, see “Sharing volumes in a 3-Cnt Ac-S

Z/Cnt Ac-J Z DC cascade configuration” (page 30).

• You can use the At-Time Split operation on BC Z pairs whose volumes are shared with Cnt

Ac-J Z S-VOLs. For more information, see “The At-Time Split for shared volumes” (page 19).

For more information about sharing BC Z and Cnt Ac-J Z volumes, see the related appendix in the

HP XP P9000 Continuous Access Journal for Mainframe Systems User Guide.

Sharing volumes in 3-Cnt Ac-J Z data center configurations

You can share BC Z pair volumes with Cnt Ac-J Z volumes in the following 3-Cnt Ac-J Z data center

(3DC) configurations:

• Multi-target

• Delta-resync

• Cascade

These sections describe the configurations and supported BC Z operations.

For more information about these configurations, see the HP XP P9000 Continuous Access Journal

for Mainframe Systems User Guide.

Sharing volumes in a 3-Cnt Ac-J Z DC multi-target configuration

You can share BC Z volumes with Cnt Ac-J Z volumes in 3 DC multi-target configurations. You can

share the BC Z P-VOL and S-VOLs with Cnt Ac-J Z volumes, as shown in the following figure.
