System Type (VSP G1000, G1500, and VSP F1500)

Storage system type: Open or Mainframe.

Journal ID

Identifier for the journal, displayed in ascending order. Blank if no number is available.

Journal Volume Selection

• Select Journal Volumes: When clicked, opens the Select Journal Volumes dialog box.

• Total Selected Journal Volumes: Number of selected journal volumes.

• Total Selected Capacity: Capacity of selected journal volumes.

Total Selected Journal Volumes

Number of journal volumes selected in the Select Journal Volumes dialog box.

Total Selected Capacity

Total capacity of the journal volume selected in the Select Journal Volumes dialog box.

Journal Type Option (VSP G1000, G1500, and VSP F1500)

Types of journal options that can be specified.

• Standard indicates the journal is associated with a UR or URMF pair.

MP Blade ID or MP Unit ID

Journal MP blade or unit. Options are:

• (VSP G1000, G1500, and VSP F1500) MPB0-MPB7.

• Auto: The default. Available when one or more MP blade or units can be assigned automatically. If Auto cannot be selected, the default is the MP blade or unit with the lowest number.

Inflow Control

Controls the flow of update data to the journal volume by slowing the response to hosts.

• Enable: The flow of update data is restricted.

• Disable: The flow of update data is not restricted.

Data Overflow Watch (VSP G1000, G1500, and VSP F1500)

Number of seconds the system will monitor metadata and journal data to the journal volume when the journal volume is full (100%). When the metadata area or journal data area are full and no more data can be stored, the system regards this as a error and suspends the pairs in the journal. Range is 0-600 seconds. The UR default is 60; the URz default is 20.

In a 3DC multi-target configuration in which three UR sites are combined, if the status of the two mirrors in the primary site is Active and the free space in the journal data area or metadata area is less than a certain amount, one of the mirrors in the journal will be suspended by error, regardless of the value in Data Overflow Watch.

Data Overflow Watch (VSP Gx00 models and VSP Fx00 models)

Number of seconds the system will monitor write data to the journal volume when the journal volume is full (100%). Range is 0-600 seconds. The default is 60.

In a 3DC multi-target configuration in which three UR sites are combined, if the status of the two mirrors in the primary site is Active and the free space in the journal data area or metadata area is less than a certain amount, one of the mirrors in the journal will be suspended by error, regardless of the value in Data Overflow Watch.

Cache Mode

Whether to store journal data in cache memory on the restore journal.

• Enable: Journal data is stored in cache memory. When the available cache memory becomes insufficient, the journal data is also stored in a journal volume.

• Disable: Journal data is stored in a journal volume instead of cache memory. This setting is disabled in the master journal. However, this setting is enabled if you use the horctakeover command of CCI (for Universal Replicator) or the YKRESYNC REVERSE command of Business Continuity Manager (for Universal Replicator for Mainframe) to change the master journal to the restore journal.

Timer Type (VSP G1000, G1500, and VSP F1500)

URz only.

Type of clock used for consistency time. Values must be the same on primary and secondary storage systems.

• System: Mainframe system clock.

• Local: Host I/O time stamp.

• None: Host I/O time stamp. Available only when copy direction is reversed, S-VOL to P-VOL.

Journal ID

Identifier for the journal LDEV, displayed in ascending order. Blank if no number is available.

Journal Type (VSP G1000, G1500, and VSP F1500)

Journal copy type, UR or URMF.

Number of Journal VOLs

Number of journal volumes registered in the journal.

Journal Capacity

Capacity of the journal volume registered in the journal. If two journal volumes are registered, the capacity of the reserve journal volume is subtracted from the total capacity.

MP Blade ID or MP Unit ID

MP blade or unit identifier

Encryption

Journal's encryption information:

• Enabled: The journal contains only encrypted volumes.

• Disabled: The journal contains only unencrypted volumes.

• Mixed: The journal contains both encrypted and unencrypted volumes.

Note: Encryption of data is not ensured in an LDEV with the Mixed encryption status. To manage data encryption, use an LDEV in which Encryption is Enabled or Disabled.

• Hyphen (-): The pool to which the journal volume belongs is an external volume, created by migration (VSP G1000, VSP G1500, and VSP F1500), or blocked.

Inflow Control

Whether flow of update data to the journal volume is restricted by slowing the response to hosts.

Data Overflow Watch (sec)

Number of seconds the system will monitor write data to the journal volume when the journal volume is full (100%). A hyphen (-) displays if Inflow Control is disabled.

Cache Mode

Indicates whether journal data is stored in cache memory on the restore journal.

(VSP G1000, G1500, and VSP F1500)

• Enable: Journal data is stored in cache memory. When the available cache memory becomes insufficient, the journal data is also stored in a journal volume.

• Disable: Journal data is stored in a journal volume instead of cache memory.This setting is disabled in the master journal. However, this setting is enabled if you use the horctakeover command of CCI (for Universal Replicator) or the YKRESYNC REVERSE command of Business Continuity Manager (for Universal Replicator for Mainframe) to change the master journal to the restore journal.

Timer Type (VSP G1000, G1500, and VSP F1500)

URz only.

Type of clock used for consistency time.
