Troubleshooting
Problem
This document provides procedure to change HMC network settings for HMC Default Gateway Address and Gateway device.
Symptom
Having HMC default gateway interface being set to "any" can cause communication problems - especially with RMC, PEP, snmptraps, and vterms.
Resolving The Problem
Use the HMC GUI or chhmc command to set the default gateway interface to eth1 then reboot the HMC.
You can change the network setting from HMC command line:
To change other network settings:
chhmc -c network
-s modify
[-h host-name]
[-d network-domain-name]
[-g gateway [-i interface]]
[--help]
Or from HMC GUI
Select HMC Management => Network Settings => Routing
Gateway address (enter Gateway IP)
The gateway device should be eth1 (eth1 specifies the open network and is used for remote HMC access, call home, and dual HMC and/or HMC/partition communications)
