Description
The number of a journal and the LDKC number. The LDKC number is enclosed in the parentheses
following the number of a journal, for example, 001 (00). A journal number ending in [&],
indicates the journal is in a 2DC configuration, for example, 001 (00) [&].
The attribute of the journal.
In case of a master journal, Attribute indicates Master. In case of a restore journal, Attribute
indicates Restore. If Attribute indicates Initial, it means that journal volumes are registered in
this journal, but no data volumes (P-VOLs nor S-VOLs) are registered in this journal. When neither
journal volumes nor data volumes are registered, Attribute indicates nothing.
The number of the journal volumes registered in the journal.
The total capacity of all the registered journal volumes.
The number of data volumes associated with the journal. When one journal uses multiple mirror
IDs, Data Volumes indicates the number of the data volumes in the journal whose mirror ID is
not Hold, Holding, or Hold(Failure).
The total capacity of all the data volumes. When one journal uses multiple mirror IDs, Data
Capacity indicates the total capacity of the data volumes in the journal whose mirror ID is not
Hold, Holding, or Hold(Failure).
Restricts inflow of update I/O to the journal volume (by delaying response to hosts).
The time (in seconds) for monitoring whether metadata and journal data are full. Data Overflow
Watch is blank when Inflow Control is No.
Indicates whether to store journal data in the restore journal into the cache.
- Used: Journal data will be stored into the cache. When there is insufficient space in the cache,
journal data is also stored into the journal volume. This setting only takes effect on the journal
volumes of RAID-5 or RAID-6.
- Not Use: Journal data is not stored in the cache.
Caution: This setting does not take effect on master journals. However, if the RAID Manager
horctakeover command is used to change a master journal into a restore journal, this setting
takes effect on the journal. If you set Use, this setting only takes effect on the journal volumes of
RAID-5 or RAID-6 that are in the journal. For external volumes, non RAID-5 journal volumes, and
non RAID-6 journal volumes, Use works the same as Not Use.
