Frame may need to be powered up in hardware discovery mode first

chsysstate -m <framename> -o onhwdisc -r sys

Check out a relatively new HMC command "chnportlogin". This will do what you are looking for.
The HMC command, chnportlogin can be used to have all the WWPNs login to the SAN, and then later used to log out the 2nd WWPN, even if AIX isn't installed on the LPAR using NPIV!. This makes it easier for storage and SAN switch administrators to do their jobs, as the storage and switch often automatically detect WWPNs logged into the SAN. Also the HMC lsnportlogin command will also be useful for this. You have to do chnportlogin -o login before any ports will show up as logged in, but after that lsnportlogin works. After all the port have been mapped by the SAN administrator, run a chnportlogin -o logout so the ones that were logged in temporarily can log out and be free to be used in an LPM operation

Pre-requisites:
• VIOS: It's 2.2.0.11-FP24 SP01 or higher
• HMC levels HMC 7.7.3, with MH01263

Hope that helps,

Hi, 

Or you can do the easy way and initiate a system plan from your HMC and then look at the result under hardware. 

Hope that helps.
