Hang of SNMP Service
SNMP Service has a module called “SNMP Extended Agent.” This module may be registered when you install some
software that uses SNMP Service.
If you start SNMP Service, SNMP Extended Agent is also loaded at the initialization. However, if the initialization is
not completed within a specified period, SNMP Service will hang.
It may take time to complete the initialization due to temporary high load on the system. In this case, wait for the
system load become low enough before restarting SNMP Service.
SCSI Status on a Data Viewer
“Unknown” is always displayed for the following items:
„ “Serial Number”, “Firmware Revision” and “ROMBIOS Revision” in “General” of “SCSI Adapter”
„ “Reassign Block Count” and “Reassign Block threshold” in “General” of “SCSI Slot”
SCSI Status while IO Module is Starting or being Stopped
While an IO module is starting or being stopped, the status of SCSI adapters, SCSI bus, SCSI enclosure, SCSI slots, and
mirror disks temporarily indicates an undefined status. Once the module is started or stopped, the status will return to
normal.
Status of SCSI Slots and Mirrored Disks at High Load
When the system load is high, the status of SCSI slots and mirror disks may not be obtained, and incorrect status may
be displayed temporarily.
Event of “ESM HAS Storage Service” when Starting the Server for the First Time
After installing the server and when it is started for the first time or when it is started for the first time after the system is
reset up, an event that SCSI-related status has changed is registered. However, the previous status in the message shows
an undefined value.
Event 401 and 402 of “ESM HAS Storage Service”
An event “Status of SCSI Slot (ID:41/n) has changed from Empty to Empty” may be registered to the event log because,
internally, there are two types of the status “Empty” which indicates that a disk is not mounted. For example, when no
disk is mounted in both Slot 1 and Slot 4, “Empty” is simply informational. Slot 1 also indicates “Empty” when a disk
that no volume is created is in Slot 4. However, if a simple volume is created on the disk in Slot 4, the status “Empty” of
Slot 1 is handled as a warning in order to maintain redundancy. In such a case, check the status of volume creation and
configure mirror volumes.
SCSI Slot Indication when a Disk Fails
When a disk which has failed before is mounted, the SCSI slot status becomes “Broken.” The status changes from
“Broken” when a mirror volume is created on the disk or any mirror volume is resynchronized.
ESMhstrg.dat
While the server is running, the “\data\ESMhstrg.dat” file in the installation directory of NEC ESMPRO Agent
(C:\ESM by default) cannot be accessed. Therefore, it cannot be backed up when using backup software. However,
there is no problem even if it is not backed up because the file is recreated at a server startup.
