Item

Description

Journal ID

Journal identifier.

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

Journal copy type, UR or URMF.

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 in a migration volume (VSP G1000, VSP G1500, and VSP F1500), or blocked.

Inflow Control

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

Data Overflow Watch

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

Whether journal data is stored in cache memory on the remote side (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 RAID Manager (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)

UR-MF only.

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

Number of Journal VOLs

Number of journal volumes registered in the journal, with the maximum number allowed in parentheses.

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.

Description

LDEV ID

Journal volume’s identifier consisting of the LDKC number, CU number, and LDEV number. Clicking the link opens the LDEV Properties window.

LDEV Name

Name of the journal volume’s LDEV.

Pool Name (ID)

Identifier consisting of the pool name and the pool ID. Clicking the link opens a window with pool information.

RAID Level

Type of RAID implementation for the journal volume.

Capacity

Journal volume’s capacity.

CLPR

Journal volume’s CLPR. The CLPR ID is displayed before the colon, and the CLPR name is displayed after the colon.

Encryption

Encryption information:

  • Enabled: Encryption of the parity group to which the LDEV belongs is enabled, or a V-VOL is associated with a pool in which a pool volume has encryption enabled.

  • Disabled: Encryption of the parity group to which the LDEV belongs is disabled, or a V-VOL is associated with a pool in which a pool volume has encryption disabled.

  • Mixed: The pool to which the LDEV belongs contains both pool volumes for which encryption is enabled and pool volumes for which encryption is disabled.

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 LDEV is an external volume. For DP-VOL, the pool to which the LDEV belongs is either an external volume or blocked.

Resource Group Name (ID)

LDEV’s resource group name and identifier. The ID is enclosed in parentheses.

Type

Type of journal volume:

  • Journal: Journal volume

  • Reserve Journal: Reserve journal volume
