Hello,
Is there a way from the HMC that I can find the WWN number of FC adapters in my system. I tried using the SMS mode of the LPAR and couldnt see the WWN information. This is needed when you trying to install LPAR (SAN Boot) and you dont know the WWN for the zonning. In our case we dont have the physicall access to the system.

Max.

Can't you pick it up from your disk sub system (if there's no switch) or from the switch?

Can't some on site read it on the back of the card for you?

You can always boot from AIX CD's to pick it up...

Another option, assign all the HBA's to a partition (current or reinstall), record all the WWN's there, and remove it again...

There are a number of ways to record the WWNs for the system - and via the HMC isn't one of them.

The easiest way is if internal disks are installed in the server they are delivered wuith a version of AIX on them - create a full system partition (using the Use all resources flag in the create LPAR profile dialogs) and boot up from on of those AIX partitions.

You can then run a script to harvest the WWNs and Location codes.

Note that this is easiest if you access the console via a terminal session from the HMC and create the console window via the mkvterm command rather than from the HMC GUI (Copying info friom that is a real pain).

If you don't have any local disks you need - as John Said - a CD or DVD available to boot the server from. AIX 6.1 comes on a DVD and will boot from that single source and proceed as above. This does however need physuical access to the server.

We further can go to the server physically and the WWN is printed on a sticker beside the FCS port on the back of the server.

The first option booting the server is nice for the SAN teams to zone as the WWNs are visible to them and they can point and click to zone everything. You can then boot your LPARS with the cards properly allocated and everything should work.

Thank You Very much.
I like the idea of assigning the adapter to an existing partition and record the WWN and then remove and reuse to the new LPAR. In my case the server is in a no man data center, server is running LPARs on the system, New adapters have been added and not sure is cabeled or not and no way I can find from the SAN zone as the zones are huge in size. No internal disks in the machine. So the best option is to assign to an existing partition.

You can do it a couple of ways. If you have SDDPCM installed, type:

pcmpath query wwpn

Otherwise:

for DEV in `lsdev | grep ^fcs | awk '{print $1}'`
do
echo "$DEV \c"
lscfg -vl $DEV | grep Network
done

Obviously, before you build the lpars, you should boot the single system image and obtain this information.

Once an LPAR is up and running you can see if a card is properly attached using lsattr -El fscsi0 (for fcs0 ) and it will show youi the state of the fibre connection.
