This mode enables/disables to output the F/M=FB
message to the host when the status of P-VOL
changes to Suspend during a TC/TCA S-VOL pair
suspend or deletion operation from BCM.
Mode 776 = ON:
When the status of P-VOL changes to Suspend
during a TC/TCA S-VOL pair suspend or deletion
operation from BCM, the F/M=FB message is not
output to the host.
Mode 776 = OFF (default):
When the status of P-VOL changes to Suspend
during a TC/TCA S-VOL pair suspend or deletion
operation from BCM, the F/M=FB message is output
to the host.
Notes:
1. Set this mode to ON in the environment where
TC/TCA for z/OS is used from BCM and the MCU
host does not need the F/M=FB message output
during an S-VOL pair suspend or deletion operation
from BCM.
2. If this mode is set to ON, the F/M=FB message is
not output to the host when the status of P-VOL
changes to Suspend during a TC/TCA S-VOL pair
suspend or deletion operation from BCM
3. If the PPRC item of CU option is set to NO, the F/
M=FB message is not output to the host regardless
of setting of this mode.
4. If the function switch#07 is set to “enable”, the
F/M=FB message is not output to the host
regardless of setting of this mode.
OFF .
