HP XP P9500 Storage - Manual (Page 149)

Description Item
Journal (continued) • Status: Indicates the status of a mirror in the local storage system.
- Initial: A mirror in initial status. Journal volumes are registered in this journal, but no data
volumes (P-VOLs or S-VOLs) are registered in this journal. If a Cnt Ac-J Z pair is created, data
volumes are registered in a mirror and the status of the mirror changes to Active.
- Active: Either of the following:
Initial copy is in progress. The P-VOL and the S-VOL are not synchronized.
Initial copy is finished. The P-VOL and the S-VOL are synchronized.
If a mirror is in Active status, some of the pairs in the mirror might be split. If this happens,
the word Warning appears. To restore such pairs, use the Pair Operation window.
- HaltAccept: An operation for splitting the mirror has been started. The status of the mirror
immediately changes to Halting. HaltAccept can indicate status of restore journal in the mirror,
but cannot indicate status of master journals in the mirror.
- Halting: An operation for splitting or deleting the mirror is in progress. The P-VOL and
S-VOL are not synchronized. Splitting a mirror changes the status in the following order:
Halting, Halt, Stopping, and finally Stopped. Deleting a mirror changes the status in the
following order: Halting, Halt, Stopping, Stopped, and finally Initial.
- Halt: An operation for splitting or deleting the mirror is in progress. The P-VOL and the
S-VOL are not synchronized.
- Stopping: An operation for splitting or deleting the mirror is in progress. The P-VOL and
the S-VOL are not synchronized.
- Stopped: An operation for splitting or deleting the mirror is finished. The P-VOL and the
S-VOL are not synchronized.
- Hold: A Cnt Ac-J Z pair for delta resync operation is created.
- Hold(Failure): An error occurred with the Cnt Ac-J Z pair for delta resync operation.
