Delete Pair operation from the RCU. In this case, you will find the suspended status at the MCU after the
Delete Pair operation from the RCU.
The Delete Pair command deletes one or more TC390 pairs. When the Delete Pair command is selected,
the Delete Pair window is displayed. Use the Delete Pair window to change the Delete Pair options (by
force and TC390A delete range) for the pair(s) selected on the Volume list of the Pair Operations window.
Figure 72 Delete Pair window (Asynchronous)
NOTE: When you set the several pairs at once and you want to keep some of the individual settings,
leave the parameter box blank. Then, only the parameters you enter are available.
NOTE: If you select a pair from the volume list and change the settings, and if you use a drop-down list to
set blank to a parameter, the parameter takes the default value for each pair. If you select the settings from
the preset list before applying the changed settings, and if you use a drop-down list to set blank to a
parameter in the Delete Pair panel, the parameter value in the preset list will not be changed.
• Volume: Device ID of the MCU.
NOTE: If # is added to the end of an LDEV number, such as 00:3F#, the LDEV is an external
volume. For more information about external volumes, see the Hitachi HPAV for z/OS user guide.
• Deleting Mode: Select the restriction on deleting a TC390 volume pair.
• Normal: Normal deleting operation is performed.
• All: Deletes all TC390 Synchronous pairs with the same MCU and RCU (same CU image) as the
selected pair. This option can be selected from the MCU or RCU, and the Force option must also be
selected. This option deletes the pairs more quickly than if you select all pairs on the TrueCopy main
window and delete them.
• Force: Overrides the restrictions on deleting a TC390 volume pair. If this option is selected, the
pair(s) will be deleted even if the MCU is unable to communicate with the RCU. This option may be
used to free a host waiting for device-end from an MCU that cannot communicate with its RCU, thus
allowing host operations to continue. If this option is not selected, the pair(s) will only be deleted if
the MCU is able to change the pair status of the M-VOL and R-VOL to simplex.
