Mode Category Description Default MCU/RCU
Note: If there are multiple response-delayed drives in the
same parity group, only the first one is blocked.
310 Common Mode 310 = ON: The monitoring timer for MP hang-up is 6
seconds and returning a response to the host within 8
seconds is guaranteed.
Mode 310 = OFF (default): The monitoring timer for MP
hang-up is 8 seconds.
Notes:
1. This SOM applies to a site where strict host response
performance is required.
2. If a hardware failure occurs when this SOM is set to ON,
the time until MPB blockage is determined is shorter
than usual.
OFF -
448 Universal
Replicator
When the SVP detects a blocked path:
Mode 448 = ON: An error is assumed and the mirror is
immediately suspended.
Mode 448 = OFF (default): If the path does not recover
within a specified period of time, an error is assumed and the
mirror is suspended.
Note: SOM 448 setting is available only when SOM 449 is set
to OFF.
OFF -
449 Universal
Replicator
This SOM is used to enable and disable detection of
communication failures 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 configuration 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 effective 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 disconnected, if
the UR pair remains in Suspending or Deleting status,
recover it in accordance with the procedure in Recovery
from UR Failure in TROUBLE SHOOTING section of
Maintenance Manual.

454 Virtual Partition
Manager
CLPR (function of Virtual Partition Manager) partitions the
cache memory in the storage system into multiple virtual
cache and assigns the partitioned virtual cache for each use.
If a large amount of cache is required for a specific use, it
can minimize the impact on other uses. The CLPR function
works as follows depending on whether SOM 454 is set to ON
or OFF.
