Mode Category Description Default MCU/RCU
Notes:
1. Note that behavior when this SOM is set to ON and OFF
is reversed between USP V/VM and VSP/HUS VM and
later.
2. This SOM should be applied to perform Volume
Migration or Quick Restore during maintenance
operation.
3. Set SOM 733 to ON if you want to prioritize the Volume
Migration or Quick Restore operation over maintenance
activities. In this case, maintenance activities may fail
when the Volume Migration or Quick Restore operation
works during the maintenance activities.
4. An LDEV-related maintenance operation such as LDEV
installation/removal may fail when Volume Migration or
Quick Restore takes place.
734 Dynamic
Provisioning
When exceeding the pool threshold, the SIM is reported as
follows:
Mode 734 = ON: A SIM is reported at the time when the
pool usage rate exceeds the pool threshold (warning, system,
or depletion). Once the pool usage rate falls below the pool
threshold, and then exceeds again, the SIM is reported again.
If the pool usage rate continues to exceed the warning
threshold and the depletion threshold, the SIM (SIM-
RC625000) is repeatedly reported every eight (8) hours until
the pool usage rate falls below the depletion threshold.
Mode 734 = OFF (default): A SIM is reported at the time
when the pool usage rate exceeds the pool threshold
(warning, system, or depletion). Once the pool usage rate
falls below the pool threshold, and then exceeds again, the
SIM is reported again. The SIM is not reported while the pool
usage rate continues to exceed the warning threshold and
the depletion threshold.
Notes:
1. This SOM is turned ON to prevent the write I/O
operation from being unavailable due to pool full.
2. If the exceeding pool threshold SIM occurs frequently,
other SIMs may not be reported.
3. Though turning on this SOM can increase the warning
effect, if measures such as adding a pool fail to be done
in time so that the pool becomes full, SOM 729 can be
used to prevent file systems from being destroyed.
4. Turning on SOM 741 can provide the SIM report to not
only the users but also the service personnel.

741 Dynamic
Provisioning
This SOM enables to switch over whether to report the
following SIM for users to the service personnel:
SIM-RC 625000 (DP pool usage rate continues to exceed the
threshold)
Mode 741 = ON: SIM is reported to the service personnel.
Mode 741 = OFF (default): SIM is not reported to the
service personnel.
