Journal/Mirror list (continued)
• Pair JNL: The number of a journal in the remote system. This column is blank if the attribute of the mirror is neither Master nor Restore.
• Controller ID: The controller ID (name indicating the model) of the remote system. The controller ID for HUS VM is 19; for VSP G1000 is 7; VSP is 6; and for USP V/VM is 5. This column is blank if the attribute of the mirror is neither Master nor Restore.
• Path Gr. ID: Path group IDs are used to identify path groups (i.e., groups of logical paths). Up to eight logical paths can be registered in one path group. This column is blank if the attribute of the mirror is neither Master nor Restore.
• CTG: The number of a consistency group to which the mirror belongs. This column is blank if the mirror does not have a volume pair or does not belong to a consistency group. A consistency group number displays in parenthesis, (01), and indicates that the multiple primary and secondary system share the consistency group.
• Remote Command Device: The LDEV number displays if a remote command device is assigned to the mirror; otherwise, it is blank.

Item Description
Item Description
Journal (LDKC) 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, 01 (00). A journal number ending in [&] indicates the journal is in a 2DC configuration using UR and TC; for example, 01 (00) [&].
A journal number ending in [M] indicates the journal can be used in a 3 UR DC configuration.
Attribute For a master journal, Attribute is Master. For a restore journal, Attribute is Restore. If Attribute is blank, no data volumes are registered.
Number of Journal Volumes
Number of journal volumes registered in the journal.
Journal
Capacity (GB) Total capacity of all registered journal volumes.
Data Volumes Number of data volumes associated with the journal. When the journal uses multiple mirror IDs, this field shows the number of data volumes for the mirror whose status is other than Hold, Holding, or
Hold(Failure).
Data Capacity
(GB) Total capacity of all data volumes. When one journal uses multiple mirror IDs, this field shows the number of data volumes for the mirror whose status is other than Hold, Holding, or Hold(Failure).
Inflow Control Restrict inflow of update data to the journal volume. Yes restricts inflow, No does not restrict. (slows delay response to hosts).
Data Overflow
Watch (sec) Sets number of seconds for the system to monitor write data to the journal volume, after the journal volume threshold (80%) is reached.
Data Overflow Watch is blank when Inflow Control is No.
Use of Cache Whether journal data in the restore journal can be stored in the cache.
Used: Journal data will be stored in cache. When there is insufficient space in cache, journal data is also stored in the journal volume.
This setting only takes effect on the journal volumes of RAID-5 or RAID-6. For external volumes, or non RAID-5 or RAID-6 journal volumes Not Used is the only setting possible.
- Not Used: Journal data is not stored in cache.
Caution: This setting does not effect master journals unless the CCI horctakeover command is used to change a master journal to a restore journal.
Journal Volumes
Shows a list of registered journal volumes.
- Parity Group: The parity group where a journal volume belongs.
- LDKC:CU:LDEV: The LDKC number, the CU number and the LDEV number of a journal volume.
- Capacity (GB): The capacity of a journal volume in gigabytes.
- CLPR: The number and the name of the CLPR where the journal volume belongs. Journal volumes and data volumes in the same journal can belong to different CLPRs. Journal volumes must belong to the same CLPR. A primary journal and the corresponding secondary journal need not belong to the same CLPR.
Item Description
Mirrors A list of mirrors. Information of four mirrors are displayed. If four mirrors include the mirror used by UR pairs or unused mirrors, information of those mirrors are also displayed.
- Mirror ID: indicates a mirror ID.
- Attribute: indicates the attribute of a mirror ID.
Master indicates a mirror to which P-VOLs of local system are registered. Restore indicates a mirror to which S-VOLs of local system are registered. Blank indicates that no data volumes are registered to this mirror.
- Status: The status of a mirror in the local system. For detailed information about the statuses, see Pair Operation window on page D-11.
- CTG: The number of a consistency group to which the mirror belongs. This column is blank if there is no consistency group. A consistency group number shown as 001 indicates that the multiple primary and secondary system share the consistency group.
- S/N(LDKC): The serial number of the remote system and the LDKC number.
This column is blank if the attribute of the mirror is Initial.
- ID: Remote system path group ID.
- Pair JNL: The number of a journal in the remote system.
This column is blank if the status of the mirror is Initial.
- CTRLID (Model Name): The controller ID (model name that indicates the model) of the remote system. The controller ID for HUS VM is 19; for VSP G1000 is 7; for VSP is 6; and for USP V/VM is 5.
This column is blank if the status of the mirror is Initial.
- Path Watch Time: The time for monitoring blockade of paths to the remote system. If the secondary mirror status of the primary system is Hold, the column is blank.
- Pairs: The number of data volumes registered in the mirror.
- Capacity (GB): The total capacity of data volumes registered in the mirror
- Copy Pace: The pace for an initial copy activity for one volume. One of the following appears: High, Medium, or Low. Copy Pace is blank if the mirror is a restore mirror.
- Delta Resync Failure: The processing that takes place when the delta resync operation cannot be performed.
- Transfer Speed (Mbps): The line speed (in megabits per second) of data transfer. One of the following appears: 256, 100, or 10. This setting does not take effect on master journals. However, if the CCI horctakeover command is used to change a master journal into a restore journal, this setting takes effect on the journal.
- Remote Command Device: The LDEV number displays if a remote command device is assigned to the mirror; otherwise, the field is blank.
Previous Displays detailed information about the previous journal.
Next Displays detailed information about the next journal.
