Journal Volumes window

Use this window to view detailed information about individual journals, including the mirrors and journal volumes assigned to it.

Summary section

Item	Description
Journal ID	Journal identifier.
Attribute	Whether the journal is Master, Restore, Master/Restore, or Initial (registered but no pair volumes assigned).
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.
Number of Data VOLs	Number of volumes associated with the journal. With the delta resync configuration, the number of data volumes registered to the journal of the mirrors not for delta resync is displayed. The number of volumes registered to the journal of the delta resync mirrors (whose status is Hold, Holding, or Hold(Failure)) is not displayed.
Data Capacity	Total capacity of all the associated volumes. With the delta resync configuration, the number of data volumes registered to the journal of the mirrors not for delta resync is displayed. The number of volumes registered to the journal of the delta resync mirrors (whose status is Hold, Holding, or Hold(Failure)) is not displayed.
or MP Unit ID	MP unit identifier
Encryption	Journal's encryption information: Enabled: The journal contains only encrypted volumes. Disabled: The journal contains only unencrypted volumes. Mixed: The pool to which the journal volume belongs contains two or more of the following: Volume for which encryption is enabled Volume for which encryption is disabled External volume 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 or blocked.
Inflow Control	Whether flow of update data to the journal volume is restricted by slowing the response to hosts.
Data Overflow Watch	Number of seconds the system monitors metadata and journal data 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).

Mirrors tab

This tab displays information about the selected journal’s mirrors.

Item	Description
Mirror ID	Mirror identifier.
Attribute	Whether the journal is Master, Restore, or Initial (registered but no pair volumes assigned).
Status	Mirror’s status. For definitions, see Monitoring journal (mirror) status.
Remote Storage System	Displays the following information about the system connected to the system you accessed.: Model/Serial Number: Storage system model and serial number. A hyphen displays if the mirror attribute is Initial. Journal ID: Journal identifier. A hyphen displays if the mirror attribute is Initial.
Path Group ID	Path group identifier specified during pair creation.
Number of Data VOLs	Number of volumes associated with the journal. With the delta resync configuration, the number of data volumes registered to the journal of the mirrors not for delta resync is displayed. The number of volumes registered to the journal of the delta resync mirrors (whose status is Hold, Holding, or Hold(Failure)) is not displayed.
Data Capacity	Total capacity of all the associated volumes. With the delta resync configuration, the number of data volumes registered to the journal of the mirrors not for delta resync is displayed. The number of volumes registered to the journal of the delta resync mirrors (whose status is Hold, Holding, or Hold(Failure)) is not displayed.
Remote Command Device	LDEV number of the remote command device if it is assigned to the mirror. The column is blank if the remote command device is not assigned to the mirror. A hyphen (-) indicates the remote command device cannot be assigned to the mirror.
CTG ID*	Mirror’s consistency group identifier. A hyphen indicates there is no consistency group.
CTG Utilization*	Whether the consistency group is shared by multiple storage systems. Single: The consistency group consists of a single pair of primary and secondary storage systems. Multi: The consistency group consists of multiple storage systems.
Path Watch Time*	Interval from the time a path becomes blocked to the time when the mirror is suspended. A hyphen indicates if the status of the secondary mirror on the primary storage system is Hold, Holding or Hold(Failure).
Path Watch Time Transfer*	Whether to assign the master journal’s Path Watch Time value to the restore journal. When transferred, the Path Watch Time values of the mirror's primary side (MCU) and the secondary side (RCU) will be consistent. Yes: Path Watch Time value will be transferred to the mirror's secondary side (RCU). No: Path Watch Time value will not be transferred to the mirror's secondary side (RCU).
Copy Pace*	Pace for copying data during initial copy: Slower (default), Medium, Faster. A hyphen indicates that the journal is a restore journal.
Transfer Speed*	Data transfer line speed in Mbps (megabits per second): 3, 10, 100, or 256.
Delta Resync Failure*	Processing that takes place in the event of delta resync operation failure Entire Copy, No Copy. Entire Copy: The entire P-VOL is copied to the S-VOL. No Copy: No processing occurs. The S-VOL is not updated.
Split Mirrors	Opens the Split Mirrors window.
Resync Mirrors	Opens the Resync Mirrors window.
Create UR Pairs	Opens the Create UR Pairs window
More Actions	When clicked, opens a menu for accessing: Edit Mirror Options window View Remote Connection Properties window Delete Mirrors window Assign Remote Command Devices window Release Remote Command Devices window Export window

Journal Volumes tab

This tab displays information about the selected journal’s journal volumes.

Item	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 two or more of the following: Volume for which encryption is enabled Volume for which encryption is disabled External volume 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 or DP-VOL for Mainframe, 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.
