Restore or Install AIX with a mksysb image using NIM
mksysb resource is a file containing the image of the root volume group (created with the AIXmksysb command) of a machine. It is used to restore a machine when it crashed, or to install it from scratch (also known as “cloning” a client). In a environment, we usually installed AIX on new LPARs or VIO clients from a existing mksysb rather than going for fresh AIX CD. Installing OS from existing mksysb help us to keep the customization same for all LPAR .
Assumptions:
1. The NIM client (In our example NIM Client is webmanual01) is defined on the NIM master (In our example nim01)
2. The client’s hostname and IP address are listed in the /etc/hosts file.
3. The mksysb image has been transferred or restored from TSM and resides in the NIM master nim01:/export/nim/mksysb.The size and sum command output match that from the source mksysb image.
Create a mksysb resource:
Run smit nim_mkres –> You should see a “Resource type” listing disppalyed –> Scroll through the menu list and select mksysb.
Hit enter and you will see menu below:
Prepare Bos install on client:
Run smit nim_tasks –> Select Install and Update Software and press enter–> Then select theInstall the Base Operating System on Standalone Clients –> Select the target definition ( ie the client which will be restored) –>Select the installation type–> select mksysb Select the mksysb resource webmanual01mksysb which you created in last step –> Select the SPOT for the restore / installation –
The entire bos_inst smit panel should now displayed
On NIM nim01 server ,check for correct client setup and start:
a. Check the subserver bootps is active
b. Check the subserver tftp is active
Boot client webmanual01 into SMS mode using HMC and select the option 2
Make sure you get a ping success; else, the NIM will fail. If ping failure, check the address info entered; check if the adapter is correct and if the adapter is connected into the network. When ping test OK, proceed to next step:
Go back to Main Menu and Select 5 for Select Boot Options
Now Select 1 Select Install/Boot Device and Select 6 for Network. Then Select Adapter # from previous step as option 2
Now select Normal Mode Boot and Select 1 to Exit System Management Services
At this point, you should see the BOOTP packets increase until finally the system is able to load the minimal kernel, and start the NIM install, Once loaded, you reach the AIX install menu as below , from there I have select to restore the OS on hdisk0.
Now system will install here and after installation complete you need to do post customization steps as per your environment.--

Two ways to create mksysb images in AIX
1) create on NIM server command:
nim -o define -t mksysb -a server=master -a source=<server name> -a mk_image=yes -a location=<location of the store image> <mksysb image name>
This will create the mksysb image of the client server and define it on the NIM server.
Example:
nim -o define -t mksysb -a server=master -a source=edppbuslvd01 -a mk_image=yes -a location=/nim/mksysb/edppbuslvd01_6100-04-03-05112010 edppbuslvd01_6100-04-03-05112010
server=master: server to store image, in this case is master
source=edppbuslvd01: the source of the image, which is client
location: the location of the stored mksysb image
2) create on client machine and then copy to NIM server and define on NIM server, or NFS mount the filesystem from NIM server on the client server.
let say you successfully NFS mount nim server filesystem on the client machine as /mnt.
mksysb -ieX /mnt/edppbuslvd01_6100-04-03-05112010
-e: exclude the filesystem/dir that defined on /etc/exclude.rootvg
-i: call the mkszfile command to generate the /image.data file
The /image.data file contains information on volume groups, logical volumes, file systems, paging space, and physical volumes.
This information is included in the backup for future use by the installation process.
-X: set to automatically expand the /tmp if necessary
After the mksysb image created, you need to define it on NIM server.
nim -o define -t mksysb -a server=master -a location=<image location> <image name>
nim -o define -t mksysb -a server=master -a source=<server name> -a mk_image=yes -a location=<location of the store image> <mksysb image name>
This will create the mksysb image of the client server and define it on the NIM server.
Example:
nim -o define -t mksysb -a server=master -a source=edppbuslvd01 -a mk_image=yes -a location=/nim/mksysb/edppbuslvd01_6100-04-03-05112010 edppbuslvd01_6100-04-03-05112010
server=master: server to store image, in this case is master
source=edppbuslvd01: the source of the image, which is client
location: the location of the stored mksysb image
2) create on client machine and then copy to NIM server and define on NIM server, or NFS mount the filesystem from NIM server on the client server.
let say you successfully NFS mount nim server filesystem on the client machine as /mnt.
mksysb -ieX /mnt/edppbuslvd01_6100-04-03-05112010
-e: exclude the filesystem/dir that defined on /etc/exclude.rootvg
-i: call the mkszfile command to generate the /image.data file
The /image.data file contains information on volume groups, logical volumes, file systems, paging space, and physical volumes.
This information is included in the backup for future use by the installation process.
-X: set to automatically expand the /tmp if necessary
After the mksysb image created, you need to define it on NIM server.
nim -o define -t mksysb -a server=master -a location=<image location> <image name>
