5. Show Status and LED/LCD Display of an LPAR

lsrefcode -m pserver -r lpar --filter "lpar_names=mylpar" -F lpar_name:refcode

You can even see the history of LED codes. Just use -n for the last NUM codes. For example, if you want to see the last 5 LED codes of an LPAR type

hscroot@umhmc> lsrefcode -m pserver -r lpar --filter "lpar_names=mylpar"  -n 5 -F lpar_name:refcode
mylpar:
mylpar:0c33
mylpar:
mylpar:0539
mylpar:0538
... and for the status LEDs:

hscroot@umhmc> lsled -m pserver -r sa -t virtuallpar --filter ""lpar_names=mylpar""
