NIM Setup:

=======Install nim server file sets======

# lslpp -l | grep -i nim
# installp -Ld /dev/cd0 | grep nim

bos.sysmgt.nim.master
bos.sysmgt.nim.spot
> Above file sets are required for nim server

# installp -agxd /dev/cd0 bos.sysmgt.nim.master

# lslpp -l | grep -i nim

======NIM server LLP_SOURCE and spot Configure=======
# oslevel -s
for starting nim  deamons, there will be entry in /etc/niminfo and certain objects and classes are to be added in ODM.
BOS CD
Configure this server as nim server as nim master server====

# smitty nim
-------------
>> Configure NIM environment
perform NIM s/w installation and Maintenance tasks
perform NIM administration tasks
Create IPL ROM Emulation Media
NIM powers Tools
Thin server maintenance

>>Configure Basic NIM Environment (Easy startup)
Advance Configuration

Primary interface for NIM master server  = en0
Input devices for installation Images  = cd0
LPP_SOURCE Name     = AIX53TL12LPP
LPPSOURCE Directory    = /newpartition/LPP_SOURCE (For each LPPSOURCE it is required around 3GB)
   Create new file system for LLP_SOURce
   FIle System size    3500MB
   VG for new file system
SPOT NAme
SPOT Directory
SPOT FS   650MB

Remove all newly added defination if any issue  = Yes
---------------------------------------------------------
* LPP_source is created, SPOT is created with the use of LPP_SOURCE
* BOSINST_DATA created as default
# cat /etc/niminfo
# lssrc -s nimesis
# ps -ef | grep -i nim    ===> /usr/sbin/nimesis -s daemon started.
# lsnim
# lsnim -c machines
# lsnim -c networks
# lsnim -c resouces
# lsnim -l AIX53TL12LPP
# lsnim -l AIX53TL12SPOT
-----------------------------------------------------------
===== How to define client in NIM master =====
* Host entry of client in NIM master and perform below tasts.

Operations to perform:
----------------------
diag = Enable machine to boot a diagnostic image
cust = perform s/w customisation
>>> bos_inst = Perform bos installation.  OR smitty nim_bosinst (Network Installtion.)
maint= Perform s/w maintenance =======> When system passwd recover/ root file system got corrupted / System log device got corrupted / Superblock got corrupted.
In this we don't boot machine by CD, We change the current state of machine to maint mode and we do fsck and all troubleshooting steps.

reset = If client's mode is maint mode and we want to reset the client state.
fix_query = Perform queries on installed fixes.
check = Check the status of nim object.
reboot = reboot the specified machine.
maint_boot = enable machine to boot in maintenance mode.
showlog = display log in nim environment.
lppcheck = verify installed filesets.
restvg = Perform restvg operation.
Linus inst = Operation to install linus onto a standalone.
Update_all = Update all currently installed filesets.

OR
# smitty nim_bosinst
Select machine > Installation type > rte - Install from installation image (Fileset base) > select LPP SOURCE > SPOT
Accept License = yes
Initiate reboot and installTION NOW = No
Check the BOS installation is initialised or not > Once initialised, go to client machine and boot machine in SMS mode.
# lsnim -l client1
cstate = BOS installation has been enabled.
If don't to install client, reset the cstate of nim client.
# nim -o reset client1
cstat = Ready for nim operation.


====== How to remove client from nim defination =======
# nim -o remove client1
It will not work as it has allocated resources and need to be deallocate.
# nim -o deallocate -a lpp_source=AIX53TL12LPP -a spot=AIX53TL12SPOT client1
# nim -l client1
# nim -o unconfig master
>>> it removed all objects and also the /etc/niminfo file. No nim command will work.

To uninstall filesets:
# insatllp -u bos.sysmgt.nim.master
# insatllp -u bos.sysmgt.nim.spot
# lslpp -l | grep -i nim
