Multiple hard disks
are taken offline at a
time.
Could be system-level
problem. For example, if the
hard disks in a JBOD system
are offline unexpected, poor
cabling in SAS or SAS expan-
sion chain would also lead to
unexpected hard disk offline.
In addition, poor heat ventila-
tion, unstable power supply,
or hardware quality issues
could also lead to offline of
multiple hard disks.
Use array recovery utility to the RAID
configurations. See the User’s man-
ual for more details.
The Web GUI can not
be connected.
The management network
interface is not configured
properly.
Check if the LED indicators of the
Ethernet port are lit up properly
(refer to the hardware manual for
details), and the IP address has to
be set to enable the network
interface. You can manually set the
IP address by the LCD, or use a
DHCP server on the
network.
