Troubleshooting
Use the following tables to help you troubleshoot various conditions that might occur on your NAS system:
l Table 10 -1 , " General Troubleshooting "
l Table 10 -2 , " NAS Manager "
l Table 10 -3 , " Server for NFS "
l Table 10 -4 , " Macintosh and AppleTalk "
l Table 10 -5 , "Hardware-RAID NAS System Internal RAID Controller Card"
Table 10-1. General Troubleshooting
NOTE: Some of the procedures refer to a software-RAID, a hardware-RAID, and an external storage configuration NAS system. For instructions on how
to determine the configuration of your NAS system, see " Determining a NAS System's Configuration " in " NAS Manager ."
Issue Possible Cause Resolution
I just created a new volume on my
system but cannot see the volume on
Windows Explorer through Remote
Desktop.
Remote Desktop cannot update to
show a new volume during the session
in which it was created.
Log off Remote Desktop. When you reconnect to Remote Desktop, the
volume should be visible.
I see the following error message in
the event log:
WMI ADAP was unable to load the
winspool.drv performance library due
to an unknown problem within the
library: 0x0
This is an issue with the WDAP
Performance library and is documented
on Microsoft's website.
Connect to the system via Remote Desktop, and then open a local
command prompt. Type the following command: WINMGMT/CLEARADAP.
When the prompt returns, type WINMGMT/RESYNCPERF winmgmt service
PID
.
I have just enabled FTP services on my
NAS system, but I am unable to upload
files using FTP even though I am the
administrator.
By default, no user has write
privileges on the default FTP site.
The FTP permissions must be configured using the Microsoft Management
Console (MMC). To access the MMC, log into Remote Desktop. Right click
My Appliance, and select Manage.Double-click internet Information
Services, and then right-click FTP Sites. Set the permissions in the FTP
Sites Properties window.
I have deleted an FTP share and folder
from my NAS system. However, when I
use Remote Desktop to confirm the
removal, I can still see the shared folder
in the FTP section of the MMC.
By default, this folder is not deleted by
the NAS Manager.
Manually remove this listing from the listed shared folders in the FTP
section of the MMC.
I cannot connect to or ping the NAS
system after turning it on.
The NAS system has not finished
booting.
Wait at least 5 minutes for the NAS system to finish booting.
If your NAS system uses software RAID and you still cannot connect,
attempt the procedures in " Troubleshooting Software-RAID NAS Systems "
in " Recovering and Restoring the System ."
If your NAS system uses hardware RAID and you still cannot connect,
attempt the procedures in " Troubleshooting Hardware-RAID NAS
Systems " in " Recovering and Restoring the System ."
I cannot connect to the NAS system
using the IPX protocol.
IPX networks require that you assign
an IPX network number to all clients.
By default, the NAS system does not
assign an IPX number to the network.
Change the IPX protocol on the NAS system to manually detect frame
types. See " Configuring the IPX Protocol " in "Advanced Features."
After restoring files from a backup, the
modified dates of folders are
inconsistent.
The modified dates of folders reflect
either the date you performed the
restore or the date the folder was
modified.
Do not take action. This design issue occurs only with folders; the files'
modified dates are consistent.
When connecting to my NAS system
using Remote Desktop, I receive a
message that the Terminal Server has
exceeded the maximum number of
allowed connections.
The NAS system supports only two
current Remote Desktop sessions at a
time.
Log off of the other Remote Desktop sessions.
The system summary and the task
manager show twice as many
processors as are actually installed in
the system.
The NAS system provides a
hyperthreading option, which allows
one physical processor to appear to
the operating system and other
applications as two logical processors.
Do not take action. Your NAS system is operating correctly.
The NIC LED on the front panel of the
NAS system is not lit.
A network connection problem exists. Ensure that a network cable is properly connected to one of the NIC
connectors on the back panel of the NAS system. Do not use a crossover
cable. If the NIC LED is still not lit, see "Troubleshooting an Integrated
NIC" in your system Installation and Troubleshooting Guide.
The monitor screen is blank when
connected to the NAS system.
The video cable may not be connected
securely or the monitor may be faulty.
Inspect the video cable connection and ensure that the cable is
connected properly to the NAS system.
Try to connect to the NAS Manager using a client system. If the client
system is able to connect to the NAS Manager, replace the monitor.
All four hard-drive operation LEDs on
the NAS system are blinking green.
The green flash pattern indicates that
the RAID volumes are being rebuilt.
Wait at least 5 minutes, and then try to reconnect to the NAS system.
