Configurin EMC SAN disks on AIX

This may sound like an absolute rookie question, and it is.

I have been working on Migrating our HP and Solaris servers to the new EMC SAN and know the routines backwards.

Now we've suddenly got a new IBM server and I don't even know how to check if it is connected to the switch.
Can someone give me detailed instructions - or a doc reference - on how to configure the FC?

Hopefully after that it will be smooth sailing with the EMC naviagent and power path software.

It is a system P6 running AIX 5.3.
I have connected the fibre cable between the server and the switch, and the switch port is active and saying "In_Sync"

I should know better, search before you post....
I found some answers here in the forums.

Removed the devices and ran cfgmgr and it all came up fine.
