HP P9000 Continuous Access Synchronous for Mainframe Systems User Guide (AV400-96398, October 2011)

This dialog box lets you view details for a selected Continuous Access Synchronous Z pair.
DescriptionItem
The following displays in the order shown:M-VOL and R-VOL areas
• LDKC number, CU number, and device ID
• Emulation type
• Capacity (number of cylinders)
Local volume’s cache logical partition number and name.CLPR
Status of the pair’s local volume. For descriptions of pair statuses, see “Pair status definitions”
(page 61).
Pair Status
Progress of the initial copy as a percentage.Pair Synchronized
If you selected an M-VOL , the serial number of the RCU (remote system), and the SSID. If
you selected an R-VOL, MCU (main system) information is shown.
RCU (or MCU) S/N and
SSID
Controller ID and model name of the remote system.Controller ID
• 6 is the controller ID and P9500 is the model name.
• 5 is the controller ID and XP24000/XP20000 Disk Array is the model name.
• 4 is the controller ID and XP12000 Disk Array/XP10000 Disk Array is the model name.
Data path channel type.MCU-RCU Path
Program product pair type (TC). Synchronous or Synchronous-CUpdate Type
Number of tracks copied per interval during the initial copy. Copy pace can be 3 tracks
or 15 tracks.
Copy Pace
This field displays only when the M-VOL is selected. It is disabled when the status becomes
Duplex.
Order in which initial copy/resynchronizing operations are performed on multiple pairs.Initial Copy Priority
This field displays only when the M-VOL is selected. It is disabled when the status becomes
Duplex.
This value is 0 for pairs created with the CESTPAIR TSO command or Business Continuity
Manager.
The M-VOL shows Never, Data, or Status. For more information, see prerequisites in “Create
pairs” (page 55).
M-VOL Fence Level
Indicates whether write I/O to the R-VOL is enabled or disabled. When Enabled,
“Enabled/Received” or “Enabled(Not Received)” appears depending on whether I/O has
been received by the volume.
R-VOL Write
Date and time the pair was created.Paired Time
Date and time pair status was last updated.Last Update Time
Amount of time for the actual pair creation to complete. This differs from the time displayed
in the Copy Time field on the History window, which includes the extra time used by the
system to receive the request and start the operation.
Pair Copy Time
This field displays only when the M-VOL is selected.
Indicates whether or not the host I/O timestamp is transferred from the M-VOL to the R-VOL.Time Stamp
Method by which differential data is stored: by cylinder or by track.Difference Management
Indicates whether CFW data is copied to the R-VOL or not. The Only M-VOL setting is
recommended because copying CFW data impacts storage system performance and it is
CFW Data Copy
typically used for temporary files (for example, sort work datasets), which are not usually
required for disaster recovery.
