Hitachi TrueCopy for IBM z/OS User and Reference Guide (T5211-96001, June 2007)

Performing TrueCopy for z/OS Pair Operations 6-17
Hitachi Universal Storage Platform V TrueCopy for IBM z/OS User’s Guide
M-VOL and R-VOL:
• LDKC number, CU number, and device ID
• Device emulation type
• Capacity (number of cylinders)
Note: If "#" is added to the end of the device ID (i.e. 00:00:3F#), the LDEV
that the LDEV number indicates is an external volume. For details on an
external volume, please refer to the Universal Volume Manager User's Guide.
CLPR: The CLPR number and the CLPR name of the volume on the primary
site are displayed.
Pair Status: Current TCz pair status of the selected volume: simplex,
pending, duplex, or suspend, suspending, deleting. If the pair status is
suspended, the suspend type and consistency status (TCzA only) are also
displayed.
Pair Synchronized: For pending duplex pairs, this value indicates the
percent completion of the initial copy operation. For duplex TCz Synchronous
pairs, this value is always 100% after the initial copy operation is complete.
For TCzA pairs:
• For a duplex TCzA pair, this value indicates the number of cylinders/tracks
(% of total) that are marked as modified in the bitmap for resynchronization.
The total number of cylinders/tracks = the number of M-VOL cylinders/tracks
(since the R-VOL can be larger than the M-VOL).
• For a suspended TCzA R-VOL, this value indicates the number of
cylinders/tracks (% of total) containing recordsets lost at the RCU (reached
the RCU but not settled before suspension).
• For a suspended TCzA M-VOL, this value indicates the number of
cylinders/tracks (% of total) which contain:
– Tracks that have not yet been copied by the initial copy or resync copy
operation (this applies only when suspended during initial copy or during
resync copy)
– Records updated by the primary system after suspension
– Recordsets lost at the MCU (created but not sent to the RCU before
suspension)
– Recordsets lost at the RCU (if the MCU can get this information from the
RCU).
RCU S/N and SSID: S/N and SSID of the RCU (or MCU if connected to the
RCU).
Controller ID: allows you to select the controller ID of the RCU. The
controller ID for USP V is 5, the controller ID for TagmaStore USP/NSC is 4,
and the controller ID for 9900V is 3. The model name is displayed next to the
controller ID.
