HP EVA Array iSCSI Connectivity Option - Manual (Page 175)

Figure 74 Port IP address conflict blink pattern
Using the CLI or GUI, the IP address conflict blink pattern may be cleared using the Beacon OFF function.
Over-temperature blink pattern
An mpx100/100b over-temperature condition is indicated with a five-blink pattern followed by a
two-second pause. The five-blink error pattern indicates that the air temperature inside the mpx100/100b
has exceeded the failure temperature threshold at 70 °C (see Figure 75 ).
Figure 75 Over-temperature blink pattern
If the Heartbeat LED shows the over-temperature blink pattern, do the following:
1. Inspect the chassis air vents. Are the intake and exhaust vents clear?
• If yes, continue with the next step
• If not, remove any debris from the fan intake and exhaust. If the condition remains, continue
with the next step.
2. Consider the ambient air temperature near the mpx100/100b and clearance around the
mpx100/100b. Make necessary corrections.
3. If the condition persists, power down the mpx100/100b. Contact your authorized maintenance
provider.
mpx100/100b log data
The mpx100/100b maintains a message log that can be displayed through the CLI or the mpx
Manager GUI. The message log is persistent up to 256 MB of log entries and is maintained across the
mpx100/100b power cycles and reboots.
The three log message categories are:
• Informational
• Error
• Fatal
See “ Log data ” on page 179 for more information.
The mpx100/100b statistics
Statistics are available from the mpx100/100b for the Fibre Channel and iSCSI ports, and can be
displayed through the CLI or the mpx Manager GUI. See “ Show Stats command ” on page 168.
Troubleshooting LUN presentation from the EVA to the iSCSI
Initiator
This section describes basic troubleshooting when presenting a LUN from the EVA to the iSCSI Initiator.
In this process it is important to focus on the EVA port and the LUN because they must be presented
throughout the Fibre Channel and IP networks to the iSCSI Initiator.
