HP XP7 Storage - Manual (Page 67)

- Disable: Journal data will not be stored in cache but in the journal volume. Disable is the
only setting possible for non-RAID-5 or RAID-6 journal volumes and external volumes.
NOTE: This setting does not effect master journals unless the Business Continuity Manager
YKRESYNC REVERSE command is used to change a master journal into a restore journal.
13. Optional. For Timer Type, specify the type of clock used for consistency time. The specified
value must be the same for the primary and secondary system.
- System: Uses the mainframe host system clock. The host MVS IOS routine attaches time-stamp
information from the time-of-day (TOD) clock to each write I/O operation. The time-stamp is
transferred to the primary system at the beginning of each I/O operation.
- Local: Uses time stamp information from the host I/O time stamping function. The mainframe
system clock is not used.
- None: Uses time stamp information from the host I/O time stamping function. None is available
only when copy direction is reversed, that is, S-VOL-to-P-VOL.
