Impact When Module Status Changes
PCI 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 another module's error. Therefore,
you need to check the status of the other modules based on alert information.
Status Color after Mounting a Hard Disk Drive
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.
Total Status of the PCI Module
When each module's status is simplex, the total status of the PCI module displayed on the Data Viewer is yellow
(warning) and the status will be reflected to the server status. The ft control software 3.0 or later does not display the
information on Ethernet or SCSI adapter on the tree of the Data Viewer. If an error occurs on an Ethernet or SCSI
adapter, view the alert reports.
Hard Disk Drives Mirrored by the Rapid Disk Resync (RDR) Function
The Data Viewer's [Mirror Disk] tree of [ft] shows a pair of hard disk drives constructing mirroring as one mirror.
Therefore the status of a volume (such as span volume and striping volume) over multiple hard disk drives created by
the RDR function may not be displayed correctly. Use the RDR Utility for checking the state of mirrored hard disk
drives created by the RDR function.
The Information on the Hard Disk Drive in the Disk Expansion Unit is not Displayed Correctly.
When the Disk Expansion Unit is mounted, the information on the hard disk drive in the Disk Expansion Unit may not
be displayed on the [SCSI Enclosure] – [SCSI Slot] information on a Data Viewer. In such case, reboot the system.
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 temporary 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 Fault Tolerant Server 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.
Community Authority
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."
