Today i attended a case about VIO servers AIX is not a system you touch every day either VIO servers if you don’t know what VIO server are here is an extract about them from the IBM site:
VIO technology is based on the idea of having special LPARs that manage the disk and network resources that other LPARs use on the same pSeries or IBM System p servers. Instead of the individual network and disk resources being carved out on an LPAR-by-LPAR basis (especially in cases where there wouldn’t be sufficient resources for all the LPARs to possess what they require to function), one or two VIO servers are given control of these resources and share them out to the other LPARs (VIO client LPARs).
First thing you need to know is that VIO servers work like a box and inside that box there are different nodes if you need to do some work on those servers you must get the padmin password which normally is a unique password for all the hosted machines, once you have done that you issue the following command to switch to the root account:
$oem_setup_env
This command does the following:
oem_setup_env: This command is the equivalent of runningsu rootbut without the need to enter a password. Again, you will rarely have to become root on a VIO server.
the work I was performing was the validation of a fiber optic, regular AIX commands like:
ifconfig -a
netstat – dt interface
lscfg -vl item
This is all for now see you later. Thanks to the Engineer Isis Sancler.
