Replicator
This SOM is used to enable and disable detection of
communication failur
es between the MCU and RCU.
Mode 449 = ON (default): On the MCU side,
checking read journal disruption from RCU is
disabled, and monitoring read journal failures is
disabled on the RCU side.
Mode 449 = OFF: Detecting communication failures
between the MCU and RCU is enabled.
Notes:
1. This SOM applies when disabling the detection
of communication failures between the MCU
and RCU in UR conguration is required.
2. When this SOM is set to ON, SOM 448 does not
work.
3. This SOM setting is not changed by microcode
upgrade.
4. This SOM is not eective for remote paths
between an Initiator port on the MCU and a
Target port on the RCU.
5. While a path from the RCU to MCU is
