Locate WWN from console on ESXi 5.x

Sometimes for urgent cases it can be necessary to obtain the HBA's WWN's to get the storage zoned before the network configurations are done and the hosts are online. On Blade servers, this info can be found on the enclosure OA but for rack mounted servers you can only get it from the console.

From the console (press Alt-F1 at the console, remember to enable shell access first under troubleshooting) login as root and run the following command:

# esxcfg-scsidevs -a

look for the lines starting with vmhba1 and vmhba2 (vmhba0 is typically the scsi controller) and the fc.XXX:XXX. The last numbers after the ":" is the WWN (see screen dump below)
