Script to reset NIM state and deallocate resources -

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):

# You need to add parameter $1 as the name of the lpar (machine resource) to the script:
#
# Check machine resource exist on NIM:
lsnim -c machines|grep "$1" 1>/dev/null
if [[ $? -eq 0 ]] ; then
   echo
    else
       echo "ERROR: $1 machine resource does not exists on NIM." && exit 1
fi
#
nim -Fo reset $1
nim -Fo deallocate -a subclass=all $1

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
