How to display the AIX boot disk

The boot disk is -- most of the time -- "hd5" under AIX.

To know where this disk is positioned is rather easy, just use the lspv command like this:

# lslv -m hd5
LP    PP1  PV1               PP2  PV2               PP3  PV3
0001  0001 hdisk0

In the example shown above, hd5 is on physical volume "hdisk0".

Simple, no? :-)
