Mode 734 = OFF:
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 option is turned ON to prevent the Write I/O
operation from being unavailable due to pool full.
2. If the pool threshold exceeding 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, system option mode 729
can be used to prevent file systems from being destroyed.
4. Turning on system option mode 741 can provide the SIM
report to not only the users but also the service personnel.
741
The option 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:
SIM is not reported to the service personnel
Notes:
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 isn’t 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.
OFF
745
