10. To restart a pair that was deleted from the RCU, first delete the pair from the MCU, and then use the
Add Pair command with the appropriate TC390 initial copy option (Entire or No Copy) to restart the
pair.
NOTE: If a timeout error occurs after clicking the Use Time-Saving Mode option, confirm on the
TrueCopy main window for which volumes the Delete Pair operation could not be performed.
Deselect the Use Time-Saving Mode option for the failed volumes and retry the Delete Pair
operation.
Changing the Pair Options (Change Pair Option)
The Change Pair Option command changes the pair options, Fence level, CFW Data, and Error level
(asynchronous pairs only). When the Change Pair Option command is selected, the Change Pair Option
window is displayed. From the Change Pair Option window, the pair options can be changed.
Figure 68 Change Pair Option 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: The CU number and the device ID.
NOTE: If # is added to the end of a device ID, such as 00:3F#, the LDEV is an external volume.
For more information about external volumes, see Hitachi HPAV for z/OS User Guide for the
XP128/XP1024/XP10000/XP12000.
• M-VOL Fence Level (Synchronous only): Select the fence level for the new pair(s). The fence level
determines the conditions under which the MCU rejects write operations to the M-VOL. Never is
automatically set for an asynchronous pair. See ” Performing TrueCopy Pair Operations ” on page 109
for more information about this pair option.
• Never: M-VOL is never fenced.
