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 67 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.
• 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 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.
When the status of the pair that is deleted is Simplex or Deleting, the default setting is Force (cannot be
changed). When the status of the pair is not Simplex or Deleting, the default setting is Normal.
• Asynchronous Parameters, Delete Range: Select the TC390A delete range option. This option simplifies
disaster recovery operations for TC390A consistency groups at the RCU (secondary or remote disk
array).
The TC390 delete range options are:
• Group (MCU or RCU). When Group is selected, the MCU/RCU will delete all TC390A pairs in the
same consistency group as the specified pair regardless of pair status and consistency status.
