–A slash (/), the controller ID
This column is blank if the journal group does not belong to any extended consistency group.
•JNL Volumes: Displays a list of registered journal volumes.
–Parity Group: indicates the parity group where a journal volume belongs.
–LDKC:CU:LDEV: Indicates the LDKC number, the CU number and the LDEV number of a journal volume.
–Capacity: Indicates the capacity of a journal volume. The unit is cylinders if the volume is a mainframe volume. The unit is gigabytes if the volume is an
–Emulation: Indicates the emulation type of a journal volume.
–CLPR: Indicates the number and the name of the CLPR where the journal volume belongs.
•Mirrors: Displays a list of mirrors.
–Mirror ID: indicates a mirror ID.
This column is blank if the attribute of the journal group is neither Master nor Restore.
–Attribute: indicates the attribute of a mirror ID.
Initial A mirror in initial status. No data volumes are registered in the journal groups of local storage system.
Master A mirror to whom primary data volumes of local storage system are registered. Restore A mirror to whom secondary data volumes of local storage system are registered.
–Status: Indicates the status of a journal group (or a mirror) in the local storage system.
Initial | A journal group in initial status. | |
| Journal volumes are registered in this journal group, but no data volumes (primary data | |
| volumes nor secondary data volumes) are registered in this journal group. | |
| When you create a URz volume pair, data volumes will be registered in a journal group. The | |
| status of the journal group will change to Active. | |
Active | Either of the following: | |
| • | Initial copy is in progress. The primary data volume and the secondary data |
|
| volume are not synchronized. |
| • | Initial copy is finished. The primary data volume and the secondary data volume |
|
| are synchronized. |
| Note: If a journal group is in Active status, some of the data volume pairs in the | |
| journal group might be split. If this happens, the word Warning is displayed. To | |
| restore such data volume pairs, use the Pair Operation window. | |
HaltAccept | An operation for splitting the mirror has been started. The status of the mirror will | |
| immediately change to Halting. | |
Note: HaltAccept can indicate status of restore journal groups, but cannot indicate status of master journal groups.
