7-34 Troubleshooting
Module status is shown “Fault”:
→
PCI modules (IO modules), SCSI adapters, SCSI buses, and modules under the
SCSI enclosure have impact on each other. For example, when the “Status” item
of a module changes to “fault,” it may be caused by other module error. Check the
status of the other modules referring to alert message.
Status color changes to different colors after mounting a hard disk drive:
→
The status of hard disk drive and its upper component, SCSI enclosures change
while generation of the mirror is completed after mounting a hard disk drive. In
addition, it may take several minutes for OS to recognize the change of disk status
and/or disk may need to be scanned again. A status color may turn to abnormal
during the process, but it will return to normal color once a mirror is successfully
generated.
Line fault and high line load are reported:
→
The LAN monitoring function defines the line status depending on the number of
transmission packets and the number of packet errors within a certain period of
time. Thus, the LAN monitoring function may report a line fault or high line load
only in a temporary high line impedance state. If a normal state recovery is
immediately reported, temporal high line impedance may have occurred. Hence,
there is no problem.
Threshold value of LAN monitoring does not reflect:
→
Because the NEC Express5800/ft series detects hardware faults on the network in
the driver level, NEC ESMPRO Agent does not monitor line faults. Thus, the
value set for "Line fault occurrence rate" of a [LAN] tab of [NEC ESMPRO Agent
properties] in the control panel is not used.
Remote shutdown function or change of threshold value function from NEC ESMPRO
Manager cannot be used:
→
Depending on your OS type or its version, settings for community, SNMP
service’s security function, are not made, or default settings of authority are
different. To enable the remote shutdown and threshold change functions via NEC
ESMPRO Manager, make settings of community and set its authority to "READ
CREATE" or "READ WRITE."
Machine in a sleep state cannot be monitored:
→
NEC ESMPRO Manager cannot monitor the NEC ESMPRO Agent machine in
the sleep state (system standby or system halt state).
→
While NEC ESMPRO Manager monitors server shutdown, the relevant NEC
ESMPRO Agent machine may be entered into the sleep state. If so, the report
"server access disabled" is issued and the status color of the server icon becomes
gray. This cannot indicate whether the NEC ESMPRO Agent machine is shut
down or entered into the sleep state. Keep these in mind when operating the
system where systems to be monitored may enter the sleep state.
