Description
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 (THP 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 Remote Web Console 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.
Enables to change the area where the information is obtained as
the Characteristic1 item from SYMMETRIX.
Mode 745 = ON:
The area where the information is obtained as the
Characteristic1 item from SYMMETRIX is changed.
When CheckPaths or Device Health Check (1/hour) is
performed, the information of an already-mapped external
volume is updated to the one after change.
Mode 745 = OFF (default):
The area where the information is obtained as the
Characteristic1 item from SYMMTRIX is set to the default.
When CheckPaths or Device Health Check (1/hour) is
performed, the information of an already-mapped external
volume is updated to the default.
Notes:
1. This option is applied when the Characteristic1 item is
displayed in symbols while the EMC SYMMETRIX is connected
using UVM.
2. Enable the setting of EMC SCSI Flag SC3 for the port of the
SYMMETRIX connected with P9500. If the setting of EMC SCSI
Flag SC3 is not enabled, the effect of this mode may not be
achieved.
3. If you want to enable this mode immediately after setting,
perform Check Paths on each path one by one for all the
external ports connected to the SYMMETRIX. Without doing
Check Paths, the display of Characteristic1 can be changed
automatically by the Device Health Check performed once
