MKSYSB RESTORATION THROUGH NIM SERVER
Network installation manager ( NIM ) is the commonly used installation methodology in AIX operating
system . This is one of the best way of installation for any type of clients. If network aailable we can
simply install the !perating "ystem and the NIM works in master slae methodology.
#ere we go with prere$uisites and considering that you hae NIM master setup aailable with you. I mean
we are going to look at the NIM restoration steps only
%elow gien table will take you through NIM client resource allocation and de&allocation.

restore the partition) should not be higher than NIM master serer een if client partition !" leel is e$ual
to NIM master also would be fine. The below gien details will gie some lights on it

"0!T 7 +00 is the most important key resources to restore or recoer any AIX partition6 if creating "0!T

"0!T for the same !" leel of the machine which we are going to restore we must hae +00 to

NIM works based on network put one dummy I0 and host entry in to NIM master serice 8etc8hosts file. I
would re$uest you that before do any changes in any of the configuration files taking backup is mandate6
in case any issues we can simply roll back the change.
