ESMhstrg.dat:
 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":
 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:
 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.
Data viewer is not displayed normally when the PCI module (IO module) is running
in the simplex mode.
 When only the PCI modules (IO modules) is running in the simplex mode (non-
duplexed mode), the data viewer cannot display the status of the SCSI enclosure
and mirror disk. To check if the duplex mode is changed to the simplex mode,
check the event log or alert viewer log, or the status color of the PCI module by
the data viewer.
