HOWTO: Install a NIM server User Rating: / 29 PoorBest  Written by Michael Felt    Page 2 of 9 NIM installation scenarios There are two basic scenarios for installing NIM servers. In this article ROOTvg.NET provides instrustions for the first scenario. In other articles on ROOTVG.NET there are instructions for updating NIM servers, in particular using SUMA: Install AIX NIM from a CD without updating the nim resources to the latest levels (i.e. I only use DVD images I have in house) Install from a DVD then use SUMA or Fix Central to update the system that will function as NIM server before creating the nim resources, especially before installing the nim spot and master filesets. Key elements Install AIX base system Create a volume group for NIM resources Create a mksysb file to be used later as nim resource Complete AIX installation and add SSH support Configure NIM master Define Installation Resources Define and Install NIM clients - hands free Install AIX base system Personally, I prefer installing a NIM server outside of a POWER system as a stand-alone unit - use older systems (at least POWER4 to support all versions of AIX) - but generally I see NIM servers being installed as a partition or LPAR of a POWER system. Install AIX via the console or the HMC supplied virtual console. When the installation completes and AIX reboots - just do the minimum: accept licenses. Do not set a root password, do not setup any network configuration information. Ideally, you will have have only one ethernet (ent0) interface configured into your partition. Create a volume group for NIM resources On a second disk I generally use the following naming scheme: Volume Group: vgNim Logical Volumes: lgNim - jfs2log - 1 partition lvtftpb    - jfs2    -  64 Mbyte as /tftpboot for when Nim spots are made lvExp    - jfs2    -   64 Mbyte as /export (/export/nim resources) lvMksb    - jfs2    -    4 Gbyte as /export/mksysb/6106 (i.e. AIX vers.) lvoslevel - jfs2 -    4 Gbyte as /export/6106 (for lpp) lvoslevels - jfs2 -   2 Gbyte as /export/6106/spot (for spot) Many people just make a very large /export partition and never think to include /tftpboot.   Example So, after the intial install of AIX and accepting the licenses, and BEFORE I enter any TCPIP information or root password I do the following: login as root Example script #!/usr/bin/ksh clear echo "AIXTOOLS and ROOTVG.NET script to assist with NIM installation based on host's oslevel" echo ========== echo Choose a disk from the list below to create and configure NIM volume group lspv echo ========== echo "Enter disk to create NIM volume group:\c" read hdisk         mkvg -y vgNim ${hdisk} [[ $? -ne 0 ]] && echo mkvg failed, exiting && exit mklv -t jfs2log -y lgNim vgNim 1 mklv -t jfs2 -y lvtftpb vgNim 64M mklv -t jfs2 -y lvExp vgNim 64M mklv -t jfs2 -y lvMksb vgNim 4G OSLEVEL=`oslevel -s | cut -c 1-2,6-7` mklv -t jfs2 -y lv${OSLEVEL} vgNim 4G mklv -t jfs2 -y lv${OSLEVEL}s vgNim 2G lsvg -l vgNim # clear # lspv hdisk0          00f67207e26dbb8d                    rootvg          active hdisk1          none                                None             # mkvg -y vgNim hdisk1 0516-1254 mkvg: Changing the PVID in the ODM. vgNim # mklv -t jfs2log -y lgNim vgNim 1 lgNim # mklv -t jfs2 -y lvtftpb vgNim 64M lvtftpb # mklv -t jfs2 -y lvExp vgNim 64M lvExp # mklv -t jfs2 -y lvMksb vgNim 4G lvMksb # OSLEVEL=`oslevel -s | cut -c 1-2,6-7` # mklv -t jfs2 -y lv${OSLEVEL} vgNim 4G lv6106 # mklv -t jfs2 -y lv${OSLEVEL}s vgNim 2G lv6106sNext before creating the filesystems, I logform (format the lgNim jfs2log). Then I create and mount the filesystems one by one. #!/usr/bin/ksh clear echo "AIXTOOLS and ROOTVG.NET script to assist with NIM installation based on host's oslevel" echo ========== OSLEVEL=`oslevel -s | cut -c 1-2,6-7` echo y | logform /dev/lgNim crfs -v jfs2 -d lvtftpb -m /tftpboot -A yes -u nim mount /tftpboot crfs -v jfs2 -d lvExp -m /export -A yes -u nim   mount /export crfs -v jfs2 -d lvMksb -m /export/mksysb -A yes -u nim mount /export/mksysb mkdir /export/mksysb/${OSLEVEL} crfs -v jfs2 -d lv${OSLEVEL} -m /export/${OSLEVEL} -A yes -u nim mount /export/${OSLEVEL} crfs -v jfs2 -d lv${OSLEVEL}s -m /export/${OSLEVEL}/spot -A yes -u nim mount /export/${OSLEVEL}/spot lsvg -l vgNim # echo y | logform /dev/lgNim # crfs -?
