Purpose

Troubleshooting Steps

Applies to:

Purpose

 Troubleshoot a problem where the ILOM NET MGT port is either non responsive or connection is lost.

Troubleshooting Steps

 A system can see symptoms of  being unable to access Host ILOM at times. and at other times able to access and use the ILOM via ssh.

1) Run a snapshot

2) Check snapshot file "@sbin@ifconfig_-a.out" which can be found in the "spos_info" directory then under the "net" directory:

EthUsb0    UP   xxx.xx.xxx.xxx  RX Pkts: 693         errors: 0        TX Pkts: 604        errors: 0
    eth0    UP   yyy.yy.yyy.yyy  RX Pkts: 52034       errors: 0        TX Pkts: 2          errors: 57021 <----note in this example the high number of errors

                                                                                                                                               note also that IP address yyy.yy.yyy.yy is that of the ILOM NET MGT port

3) Check auto negotiation setting on the corresponding switch port. It should be set for "AUTO-NEG"

4) Make sure to reset the SP from ILOM after auto negotiation setting is changed

-> reset /SP
