LAB: Configure the NIM Partitions

1. Check the network setup2. Define the NIM Master3. Create the lpp_source resource (preloaded to disk)4. Create the spot resource (from the lpp_source resource)5. Define the AIX client6. Prepare the NIM server for deployment of the AIX client

� This Lab covers the configuration of the student NIM Master� We will be displaying just one of the student’s environment

NIM Resources� NIM installation uses defined resource stored in the NIM database

– NIM master – always required

– LPP_SOURCE – contains source files (like CDROM)• Normally loaded to disk from the AIX install CDs

– SPOT – Shared Product Object Tree• Temporary /usr filesystem to mount during install

– Machine – client machine definitions• One of these is created for each client you plan to install• These also must be enabled with “smitty nim_bosinst”


IBM System p



Verify the resources

3. host sys##_aix#Odd: _aix1, Even _aix2

� Make sure that the lpp_source directory is populated# ls –l /export/lpp_source/installp/ppc

bos.sysmgt.nim.spot 6.1.0.0 COMMITTED Network Install Manager - SPOT

bos.sysmgt.nim.client 6.1.0.0 COMMITTED Network Install Manager -

� Make sure that your NIM server and clients are resolved– # host sys##_aix## (example: host sys01_aix1 (student 1))

2. lslpp –l | grep nimCheck NIM server installed

1. ls –l /export/lpp_sourceCheck for files in directory
