Re: VIOS: moving a card for the lan

bull dog determination...

Looked up chdev. It says use lsattr. Looked that up. Tried that at the
$ prompt in vios. not found
oem_setup_env
changes from $ prompt to # prompt
lsattr -E -l ent3
...
real_adapter ent0 Physical adapter associated with the SEA
...

And I noticed at the bottom of the help for chdev this little ditty:
You can use the System Management Interface Tool (SMIT) smit chdev fast
path to change device characteristics.

Well smit is like using a nice screen in 5250 land. Which is way better
than a command line with no prompting. So I drilled down into that. Found
the adapter and tried to change it. I got
<snip>
1800-109 There are currently no additional SMIT screen entries available
for this item. This item may require installation of additional software
before it can be accessed.
</snip>
Back to the command line...

chdev -l ent3 -a real_adapter=ent8
ent3 changed

lsattr -E -l ent3
verified!

lsattr -E -l ent6
real_adapter ent1 Physical adapter associated with the SEA

chdev -l ent6 -a real_adapter=ent9
ent6 changed

lsattr -E -l ent6
verified!

exit
to exit from # prompt to $ prompt

ping myibmi
0821-062 ping: host name myibmi NOT FOUND

ok, so maybe I need to reboot?

shutdown -force
Waited until I got
....Halt completed....
Verified it was "Not Activated" at the HMC.
Killed vios terminal.

Started lpar back up on the HMC.

Started vios21 terminal session. Seemed to take longer than normal but
when it eventually got there it was ok.
ping myibmi
worked!

Ok, I moved a card for lan used by one of my VIOS lpars. Luckily I had a
redundant VIOS lpar and it's carrying the ethernet load.

In vios I ran
lsdev -type adapter
and got:
So, what used to be ent0 and ent1 is now ent8 and ent9
ent0 Defined PCIe2 2-port 10GbE SR Adapter
(a21910071410d003)
ent1 Defined PCIe2 2-port 10GbE SR Adapter
(a21910071410d003)
ent2 Available Virtual I/O Ethernet Adapter (l-lan)
ent3 Defined Shared Ethernet Adapter
ent4 Available VLAN
ent5 Available Virtual I/O Ethernet Adapter (l-lan)
ent6 Defined Shared Ethernet Adapter
ent7 Available VLAN
ent8 Available PCIe2 2-port 10GbE SR Adapter
(a21910071410d003)
ent9 Available PCIe2 2-port 10GbE SR Adapter
(a21910071410d003)

I had originally created ent3 with this command:
mkvdev –sea ent0 –vadapter ent2 –default ent2 –defaultid 3999 –attr
ha_mode=auto

1) How do I change ent3 to use ent8 instead of ent0?

2) How do I display the properties of ent6 to see if I need to change it
from ent1 to ent9? The card does have two fiber ethernet cords hanging
out of it. I've looked for parameters on lsdev to get more details and
I'm missing it.

I have a ticket open with IBM. They want me to send them a snap file via
ftp. Well, if the ethernet is down it makes ftp rather daunting...
Thought about vlan, like I use for inter communications between IBM i for
PTF distribution but with my lack of knowledge on vios IDK if I want to
start messing with routing and whatnot also.
