Figure 53 Change Pair Option Dialog Box (Asynchronous)
•
Volume: The LDKC number, the CU number, and the device ID.
If the pound or gate symbol (#) is added to the end of the device ID like 00:00:3F #, the LDEV
that the LDEV number indicates is an external volume. For details on an external volume, see
the HP StorageWorks XP24000/XP20000 External Storage Software User's Guide.
•
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 will reject write operations to the M-VOL.
Never is automatically set for an asynchronous pair.
◦ Never: the M-VOL will never be fenced.
◦ Data: the M-VOL will be fenced when the MCU cannot successfully execute an update
copy operation for any reason.
◦ Status: the M-VOL will be fenced only if the MCU is not able to change the R-VOL status
to suspended when an update copy operation fails.
•
CFW Data: specifies whether the CFW data will be copied to the R-VOL.
•
Asynchronous Parameters (Async only):
◦ Error Level: error level for the new pair(s): Group, or Volume.
To set the parameters on the multiple volumes at once without changing individual parameters per
volume, make the box of parameters that you do not want to change blank. Only the parameters
that you input will be changed.
The Cancel button cancels the settings you have made and closes the Change Pair Option dialog
box. The Set button sets the parameters and closes the Change Pair Option dialog box.
To change the fence level, CFW data, or error level pair option for one or more pairs:
1. Connect to the MCU of the pair(s) for which you want to change the option(s), and open the
TrueCopy for Mainframe Pair Operation window.
2. In the tree, select the CU or the upper CU grouping, which contains the M-VOL(s) of the pair(s).
