Troubleshooting

No link LEDs vi
sible on RAID
controller (rear)
If you are using a network switch, verify
that it is
powered on and Ethernet ports on both the network
switch and RAID controller are active. Also, make
sure the storage
array enclosure is powered on.
Reduced throughput
If you have connectivity but are experiencing
reduced throughout, make sure your iSCSI port is not
connecting to the host server through a slower
-than-
expected speed. For example, a 10Gb port can
connect using a 1Gb network switch, but the slower
switch wi
ll impact throughput.
Troubleshooting Management Port IP Addressing and Configuration
If problems persist, refer to the following table:
Table 5. Diagnosing Management Port Configuration Problems
Issue/Problem
Recommendation
What is the IP address
of the Ethernet
management port?
The management port appears differently
to DHCP and non-DHCP
servers:
DHCP server
(IPv4)
On a network running DHCP server, IP
addresses for the Ethernet management ports
are assigned automatically
non-DHCP server
(IPv4)
On a non-DHCP network server, the Ethernet
management ports will default to the following
IP addresses following a three-minute timeout
(from initial polling or connection attempt):
Controller 0:
192.168.128.101
Controller 1:
192.168.128.102
Subnet mask:
255.255.255.0
All IPv6-enabled
configurations
Each management port has a default link local
IP address that is based on the MAC address of
the port (unless IPv6 is specifically disabled on
a port).
