Sometimes we need to reset the state of a lpar on our NIM server. You can use smitty, but it’s simpler to use a shell script.
First, we check the which NIM resources our LPAR has inside NIM:
[root@nim] lsnim -l lpar1 lpar1: class = machines type = standalone current_master = nim connect = nimsh (secure) sync_required = yes platform = chrp netboot_kernel = mp if1 = ent-Network9 lpar1 0 cable_type1 = N/A Cstate = BOS installation has been enabled prev_state = ready for a NIM operation Mstate = currently running lpp_source = LPP_INS_AIX61 spot = spotimagen_aix6 cpuid = 000U040AD401 control = master
As you can see, lpar1 has two resources, one lpp_source and a spot resource.
Now. it’s time for this script (resetaix.ksh):

Check again machine resources:
[root@nim:/usr/local/bin] lsnim -l lpar1 lpar1: class = machines type = standalone current_master = nim connect = nimsh (secure) sync_required = yes platform = chrp netboot_kernel = mp if1 = ent-Network9 lpar1 0 cable_type1 = N/A Cstate = ready for a NIM operation prev_state = BOS installation has been enabled Mstate = currently running cpuid = 000E050AD400 Cstate_result = reset
Just thanks if the post was helpful 🙂
