New to AIX: How do I setup high availability on an AIX System
I am new to AIX but not new to unix.
I have an interview for an AIX systems admin position and I know they want someone who has knowledge of High Availability, Failover and LPARs
From my research so far, It appear powerha is used to setup high availability and failover on Power systems but is this the case for all AIX systems or does it differ?
I found documentation on IBM Knowledge Center for setting up High availability using PowerHA but I do not know if this would be the process on all aix systems.

Hi all
I was just wondering what modes AIX supports for port trunking ( bonding, etherchannel, link aggregation or whatever you want to call it )
