Scripts

lparwwpn

Script to list out an LPAR's WWPNs. Due to the nature of the restricted shell, you need to first source in the functions to use it. This takes functions from Brian Smith's ezh script, which I also recommend using.

For example, if you copy the script into your home directory as lparwwpn.
