Recognizing Issues Involving the Ethernet Management Port

Problems occurring due to misconfigured or nonfunctional Ethernet management ports on your storage
array's RAID controller modules can appear in a number of different ways. However, typical
management port issues may include:
−
Status LEDs on iSCSI ports not lit or indicating fault (refer to Table 2 for LED values)
−
Unable to ping an iSCSI port from the host server on the same subnet
−
Dynamic Host Configuration Protocol (DHCP) is unable to assign an IP address for one or more
of your RAID controller modules
−
Duplicate IP addresses appear (either manually set or multiple arrays with the same factory
default IP addresses)

Basics: Cabling, Power and Network Switches

Simple issues, such as an improperly seated Ethernet cable or a defective and/or powered-down
hardware component, are often the root cause of a number of problems. If a physical link error occurs
or you are unable to connect to a storage array in MD Storage Manager, it is always useful to perform a
simple, standard troubleshooting protocol:
1. Verify you have a solid, well-seated connection between the RAID controller module's Ethernet
management port(s) and your host server and/or network switch.
If you are using a network switch, verify the following:
2.
All active link and link status LEDs are lit (an unlit activity LED is not necessarily a
-
problem)
The Ethernet switch you are using is compatible with your RAID controller module (for
-
example, is compatible with 1Gb MD3200i-series and/or 10Gb MD3600i-series arrays)
Do not connect an Ethernet switch with a speed of less than 1Gb to the storage array
-
3. Verify that MD-series storage array enclosures and RAID controller modules are powered on and
show the proper LED status configurations. (See Table 2.) For additional MD-specific LED
diagnostic information, see support.dell.com/manuals.
4. Ensure that all cabling and connectors are functional. If uncertain, swap current cables with
known good cables to determine if the problem is related.
