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 system 390 User Guide for the
XP12000/XP10000.

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
for more information about this pair option.
• Never: M-VOL is never fenced.
• Data: M-VOL is fenced when the MCU cannot successfully execute an update copy operation for
any reason.
• Status: M-VOL is fenced only if the MCU cannot change the R-VOL status to suspended when an
update copy operation fails.
•
CFW Data: Specifies whether the CFW data is copied to the R-VOL. For TCPD-MF, only Copy to R-VOL
is available.
•
Asynchronous Parameters (Async only):
• Error Level: Error level for the new pair(s): Group, or Volume.
NOTE:
To set the parameters on multiple volumes at once without changing individual parameters

ICKDSF considerations for TrueCopy volumes
The XP12000/XP10000 supports the use of the ICKDSF utility program. ICKDSF performs functions for the
installation, use, and maintenance of DASD as well as service functions, error detection, and media
maintenance.
