1. To change options, see “Changing Fence Level, CFW Data” (page 83) .
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 number of VOLs. copied concurrently, other options” (page 63).
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
“Suspending pairs” (page 68).
Command device
Business Continuity Manager requires a command device for the Cnt Ac-S Z system. This command
device must be independent of a command device that may exist for a Continuous Access
Synchronous system. A command device for Business Continuity Manager must be configured from
Business Continuity Manager only. Also, please note the following:
• If you are using an XP12000 Disk Array/XP10000 Disk Array, only the volumes with a CU:
LDEV number between 00: 00 to 3F: FF can be used as command devices.
• Missing Interruption Handler (MIH) values are used as an I/O monitor time for volumes used
as command devices. Make sure to set the MIH value to 45 (seconds), minimum, from the
host.
• You can check to see if a command device already exists by using Remote Web Console, as
follows:
1. In Remote Web Console, click File > Basic Information.
2. In the Report Display window, click the LDEV tab. A command device is indicated by an
icon displaying C.
See the HP XP P9000 Business Continuity Manager User Guide for all instructions.
F/M = FB message output control option when operating S-VOLs
In Business Continuity Manager, when a pair in DUPLEX status is suspended 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 CU Option dialog box.
