1. To change options, see “Changing P-VOL Fence Level, CFW Data” (page 82) .
2. The initial copy operation follows the YKMAKE execution order.
3. See “Priority for initial copy operations and scheduling order” (page 38) .
4. The resync operation follows the YKRESYNC execution order. When YKRESYNC is performed for a consistency
group, the operation begins with the pair having the lowest number within the group.
5. To change these options, see “Setting # of vols. copied, path blockade, other options” (page 62) .
6. If you want to assign a different value to this option, use the Remote Web Console Add Pair operation. See “Creating
pairs” (page 66) .
7. If you want to assign a different value to this option, use the Remote Web Console Suspend Pair operation. See
“Splitting pairs” (page 69) .
Command device
Business Continuity Manager requires a command device for Continuous Access Synchronous Z.
It must be independent of any command device used for Continuous Access Synchronous.
Please note the following:
•
A command device must be configured from Business Continuity Manager only. However,
you can use Remote Web Console to check whether it already exists (click Logical Devices in
the Storage Systems tree).
•
Missing Interruption Handler (MIH) values are used as I/O monitor time for volumes used as
command devices. Make sure to set the MIH value to 45 (seconds), minimum, from the host.
For more information, see the Business Continuity Manager User Guide for instructions.
F/M = FB message output control option
In Business Continuity Manager, when a pair in DUPLEX status is split or released to the S-VOL,
the status of the P-VOL becomes Suspend and the F/M = FB message is output to the host connected
to the MCU. You are able to stop output of the message by setting system option mode 776.
However, the F/M = FB message is output even with system option mode 776 = ON when the
pair status is Suspend due to failure. Also, the F/M = FB message is not output regardless of the
of mode 776 setting if PPRC support by host = No is selected on the Change CU Options window.
