4. This SOM is effective within the range of each CLPR.
Therefore, an operation target LPRxx (xx= 00 to 31)
needs to be selected before setting this SOM to ON/OFF.
For example, when setting this SOM only to CLPR0
(even though this SOM is not set to CLPR 1 to 31),
select "LPR00" and then set this SOM to ON/OFF. If
"System" is selected and then this SOM is set to ON,
this SOM is not effective for any of the CLPRs.
5. Set SOM 1043 to ON when journals are not
accumulated at the RCU. If journals have already been
accumulated at the RCU, journal copy does not start
until the journal usage rate becomes 0%. (If you need
to set SOM 1043 to ON while journals are accumulated,
set Purge Suspend, and then perform resync.)
1067 Universal
Replicator This SOM is used to enable microcode downgrade to a
version that does not support URxUR (including delta).
Mode 1067 = ON: Even when a UR pair has been
registered, downgrading the microcode to a version that does
not support URxUR (including delta) is allowed.
Mode 1067 = OFF (default): If any UR pair has been
registered, downgrading the microcode to a version that does
not support URxUR (including delta) is not allowed.
Notes:
1. This SOM is applied to enable microcode downgrade to
a version that does not support URxUR (including delta)
if the configuration where any UR pair has been
registered is not URxUR (including delta).
2. Setting this SOM to ON allows microcode downgrade at
sites where only 1 mirror is used in URxUR multi-target
configuration without delta resync and cascade
configuration (L or R site in multi-target, and P or R site
in cascade), but the following phenomena occur after
microcode downgrade. Make sure that the target
storage system does not contain pairs of URxUR
configuration.
Phenomena:
1. When the microcode is downgraded at S site (local
or remote) in multi-target configuration, the pair
between P site and the target S site cannot be
resynchronized.
2. When the pair between I site and R site in
cascade configuration is resynchronized, the pair
status cannot change from COPY to PAIR.
3. When the microcode is downgraded at R site in
cascade configuration, the pair between I site and
R site cannot be resynchronized.
OFF Both
1069 Common By setting this SOM, the INQUIRY Page E3h field is changed.
The field varies depending on the combination of SOMs 972,
973, and 1069. For details, contact customer support (see
SOM1069 sheet).
