Troubleshooting 7-49
Event 401 and 402 of “ESM HAS Storage Service”:
o
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:
o
When a disk which has failed before it 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:
o
While the server is running, the “\data\ESMhstrg.dat” file in the installation
directory (default is “C:\ESM”) of NEC ESMPRO Agent cannot be accessed. For
this reason, when backup software is used, this file is not backed up. Also, because
the “ESMhstrg.dat” file is recreated while the server is running, there will not be
any problem even if the file is not backed up.
PCI Module Status is “Empty”:
o
If devices such as LANs and FCs in the PCI module are not duplicated, the PCI
module status becomes “Empty.” If the PCI module status is “Empty,” make sure
that the LAN and FC cables are connected to and LANs are teamed.
“Warning” is displayed for a “Normal” mirror volume on Disk Management:
o
If the combination of the disks that configure a mirror is different from the one
described in “Disk Operations” in Chapter 3, “Warning” is displayed for a normal
mirror volume.
