AIX

I am wondering if there is a command I can run from **with-in** LPAR server (server01) to find out the hostname or IP address or other parameters for VIO server in charge of server01?

There isn't anyway I know of to get the hostname, IP, or even the LPAR id of the VIO server your LPAR is going through. You can, however, find the serial number of your managed system and that limits down the VIO search to just the VIO servers on that physical box. You can then compare the slot numbers of the client vscsi's to those on the VIO servers and figure out where it is connected.

You can see with this output that this LPAR is running on the managed system with serial number "200888E" and is connected to a VIO server on port C60.

Code:

host:/:$ lscfg -vl vscsi0
  vscsi0           U9117.570.200888E-V6-C60-T1  Virtual SCSI Client Adapter

        Hardware Location Code......U9117.570.200888E-V6-C60-T1

host:/:$

You would then have to run an "lsmap -all" command and find this slot number on the VIO server:

Code:

vios1:/home/padmin:# lsmap -all | grep C60
vhost5          U9117.570.200888E-V40-C60                    0x00000006
vios1:/home/padmin:#

If you are using the same slot numbers on both of your VIO servers, this can complicate things a little more, but by examing the "lsmap -all" output on your VIO servers, you could figure it out.
