Today, I needed to change IP settings in one of the vMA for ESXi 4.1. I've gone through the vSphere Management Assistant Guide: no answer. Search on the Internet: no answer either.
All I see is the introduction on how to configure IP settings on the 1st time when vMA is newly installed!
After some tedious trials and errors, since I'm no longer familiar with Linux anymore, I found that vMA is based on RedHat. And so, luckily, we could run the following command to reconfigure IP settings:
sudo system-config-network
Hope this help for those who are like me.
And I've made this little document to make it easier for search: https://communities.vmware.com/docs/DOC-31011
