Command device

Business Continuity Manager requires a command device on the Continuous Access Synchronous
Z disk array that is independent of the command device for an open system. The command device
for BCM can be configured only from BCM.

To find the command device using Remote Web Console:
1.

In Remote Web Console, click File/Reports. The Report Display window displays.

2.

Click the LDEV tab.

If you are using 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.

F/M = FB message output control option when operating R-VOLs

When the suspension or the release operation is performed from Business Continuity Manager
(BCM) to the R-VOL of Continuous Access Synchronous Z pair in the Duplex status, the status of
the M-VOL becomes Suspend and the F/M = FB message is output to the host connected to MCU.
You can control the output of this message by setting the system option mode 776.

However, even if the system option mode 776 is set, the F/M = FB message is output when the
pair status becomes Suspend due to the failure. Moreover, the F/M = FB message is not output
regardless of the setting of system option mode 776 if PPRC support by host = No is selected on
the CU Option dialog box.

PPRC specifications, restrictions

Most Continuous Access Synchronous Z operations can be performed using PPRC TSO or ICKDSF
PPRCOPY commands from the host system console. All P9500 systems support IBM PPRC host
software functions.
