RAC on 5.3
I am setting this up on 5.3 and the problem is I cannot remember how to allocate two IP addresses to a NIC. I have setup an alias on EN0 but when I list it with ifconfig -a it still only shows 1 network address (after a reboot). I know there is something I must do but for the life of me cannot remember. Can anyone help please?

Using ifconfig is temporary. To make a configuration permanent you need to either configure the interface by script at boottime or write the config into the ODM. The later is done with the chdev command but if you don't feel sure footed with AIX commandline you better use SMIT instead. The fastpath is "smitty inetalias".

Thanks Shockneck that is what I thought and it was the way I had tried. My problem was I had set the alias the same as the main IP address not the alias which I found by doing an odmget on EN0. Once I had set the alias correctly I could see 2 IP addresses listed on EN0.

Many thanks for your help!
