===== Changing the CPUID of NIM Master and NIM Clients after LPM =====


==== On the NIM Client: ====

This document explains how to change your NIM Master or NIM Clients CPUID after you have moved it to new HW to match the system's new CPUID.

To check what CPUID the Master has for the NIM Client we can run the following command on the NIM Master:
<cli prompt='#'>
root@sentinel(/)# lsnim -l instlab163 | grep -i cpuid

      cpuid          = 00FF48B55C00   <---- wrong/old CPUID
</cli>

To check the current CPUID of the NIM Client:
<cli prompt='#'>
root@instlab163(/)# uname -a
AIX instlab163 2 7 00F84BE54C00
</cli>

To change the CPUID on the NIM Master’s client definition to match with the actual CPUID of the nim client:
<cli prompt='#'>
root@sentinel(/)#nim -o change -a cpuid=00F84BE54C00 instlab163
root@sentinel(/)# lsnim -l instlab163 | grep -i cpuid
   cpuid          = 00F84BE54C00  <---- correct CPUID
</cli>

We can verify connectivity:
<cli prompt='#'>
root@sentinel(/)# nim -o lslpp instlab163 | grep bos.mp
  bos.mp64                   7.2.4.0  COMMITTED  Base Operating System 64-bit
</cli>
==== On the NIM Master: ====

To check the current system CPUID:
<cli prompt='#'>
root@sentinel(/)# uname -a
AIX sentinel 2 7 00FB43B94C00
</cli>

To check the NIM Master definition:
<cli prompt='#'>
root@sentinel(/)# lsnim -l master | grep -i cpuid
   cpuid               = 00FB43C85B00  ß old/wrong CPUID
</cli>

To change the CPUID:
<cli prompt='#'>
# /usr/lpp/bos.sysmgt/nim/methods/m_chattr -a cpuid="new CPUID" master
</cli>

Example:
<cli prompt='#'>
root@sentinel(/)# /usr/lpp/bos.sysmgt/nim/methods/m_chattr -a cpuid="00FB43B94C00" master
</cli>

To verify:
<cli prompt='#'>
root@sentinel(/)# lsnim -l master | grep -i cpuid
   cpuid               = 00FB43B94C00
</cli>

===== Automaticaly restore AIX LPAR =====

==== Steps to install mksysb from NIM ====

=== On the NIM server ===

Allocate required resource 
<cli prompt='#'>
# nim -o reset -a force=yes $CLIENT_NAME
# nim -Fo deallocate -a subclass=all $CLIENT_NAME
# nim -o bos_inst -a source=mksysb  -a mksysb=$MKSYSB -a spot=$SPOT -a accept_licenses=yes -a fb_script=$SCRIPTFB -a bosinst_data=$BOSINST_DATA -a boot_client=no $CLIENT_NAME
</cli>

Monitoring
<cli prompt='#'>
# nim -o showlog -a log_type=boot $CLIENT_NAME > $LOG
</cli>

=== On the HMC ===

Now boot the partition using a specific IP, and also give the NIM server IP to boot
<cli prompt='#'>
# Syntax
To retrieve a MAC address:
lpar_netboot -M -n [-v] [-x] [-f] [-i] [-A] -t ent [-D -s Speed-d Duplex -S Server -G Gateway -C Client -K
subnetmask] partition name partition profile manage system

To perform a network boot:
lpar_netboot [-v[-x] [-f] [-i] [-g args] [-A -D | [-D] -l phys_loc | [-D] -m maddress] -t ent [-D -s Speed-d
Duplex -S Server -G Gateway -C Client -K subnetmask partition_name partition_profile manage_system
