Mode Category Description Default MCU/RCU
6. When this SOM setting is default (OFF), a delta
r
esync operation is completed without pair
status change to COPY/Pending. Therefore, if an
operation depends on the pair status changing
to COPY/Pending, such as running the CCI
pairevtwait command, set this SOM to ON.
7. When this SOM setting is default (OFF) (pair
status changes directly to PAIR/Duplex), SIMs
and SSBs that are reported due to a pair status
change to COPY/Pending are not reported.
8. If this SOM is set to ON or OFF during delta
resync, the setting is not applied. Change this
SOM setting before delta resync.
9. During delta resync, downgrading the
microcode to a version that does not support
this SOM is disabled in TC-UR delta
conī “guration. If microcode downgrade is
disabled (FunctionID:0701) when delta resync is
not in process, suspend the UR pair and then
retry the microcode replacement.
1021 Universal
Volume
Manager
This SOM can enable or disable the auto-recovery for
external volumes of an EMC storage system.
Mode 0121 = ON: An external volume that is blocked
due to Not Ready status can be recovered
automatically regardless of the type of external
storage system.
Mode 1021 = OFF (default): An external volume that
is blocked due to Not Ready status might not be
recovered automatically depending on the type of
external storage system.
Notes:
1. This SOM is applied when the auto-recovery of
external volumes that are blocked due to Not
Ready status is desired in UVM connection using
an ECM storage system as an external storage
system.
2. When this SOM is set to ON and the connected
external storage system is not in stable status
(such as failure and recovery from failure), a
blockage due to Not Ready status and auto-
recovery might occur repeatedly.
