When exceeding the pool threshold, the SIM is
reported as follows:
Mode 734 = ON: The SIM is reported at the time
when exceeding the pool threshold. If the pool
usage rate continues to exceed the pool threshold,
the SIM is repeatedly reported every eight (8)
hours. Once the pool usage rate falls below the pool
threshold, and then exceeds again, the SIM is
reported.
Mode 734 = OFF (default): The SIM is reported at
the time when exceeding the pool threshold. The
SIM is not reported while the pool usage rate
continues to exceed the pool threshold. Once the
pool usage rate falls below the pool threshold and
then exceeds again, the SIM is reported.
Notes:
1. This option 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 option can increase the
warning effect, if measures such as adding a
pool fail to be done in time so that the pool
becomes full, MODE 729 can be used to prevent
file systems from being destroyed.
4. Turning on MODE 741 can provide the SIM
report to not only the users but also the service
personnel.

The option enables to switch over whether to report
the following SIM for users to the service personnel:
SIM-RC 625000 (HDP 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
Note:
1. This option is set to ON to have SIM for users
reported to the service personnel:
- For the system where SNMP and E-mail
notification are not set.
- If Storage Navigator is not periodically
activated.
2. When MODE 734 is turned OFF, SIM-RC625000
is not reported; accordingly the SIM is not
reported to the service personnel even though
this option is ON.
