Status Color after Mounting a Hard Disk
When creating a new mirror, the status of the hard disk and its upper component, SCSI enclosure,
will continue to change frequently after you mount a hard disk until the mirror is completed.
During this process, the status color may turn to abnormal, but when the mirror is created
successfully, it will return normal.
LAN Monitoring Report
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. Thus, the LAN monitoring function
may report a line fault or high line load only in a temporal high line impedance state.
If a normal state recovery is reported immediately, temporal high line impedance may have occurred
thus there is not any problem.
LAN Monitoring Threshold
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.
Community Authority
For Windows 2000 Advanced Server, the community authority, or the security function of the
SNMP Service, is set to "READ ONLY" in default. With the community authority being "READ
ONLY, " the remote shutdown and threshold change functions are not available with NEC ESMPRO
Manager. If you desire to use these functions, set the community authority to "READ CREATE" or
"READ WRITE."
Monitoring in Sleep State
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.
