How to take
MKSYSB of AIX LPAR from NIM MASTER
During my struggling days for job when I was appeared
for interview, interviewer asked me how to take backup from NIM master, after
hearing I was completely blank. After this incident I collected all knowledge
from my friend and team-mate for how to take backup from NIM MASTER. So this blog
is for those who want to know how to take backup of AIX LPAR from NIM MASTER.
Generally command for taking AIX LPAR backup from
locally is like below.
#mksysb
–iX /tmp/aixbackup/hostname_backup
But what will procedure if AIX admin want to take
backup from NIM MASTER.
Step by step procedure to take MKSYSB backup from NIM
MASTER on AIX LPAR.
1. On NIM MASTER enter AIX LPAR hostname/IP entry in /etc/hosts file.
2. Enable rshd
on AIX LPAR by following command.
#
Chsubserver -a -v shell -p tcp6 -r inetd
# refresh –s inetd
# cd /
# rm .rhosts
# vi .rhosts
+
Here if AIX admin want to take backup of multiple AIX
LPAR then simply add + in .rhosts file.
If admin want to take selective AIX LAPR backup then
only add hostname of these LPAR in .rhosts file.
# chmod 600 .rhosts
3. Copy /etc/niminfo
file from NIM MASTER to client /etc
location
4. Execute following command to take backup of AIX
LPAR from NIM MASTER.
#
nim -o define -t mksysb -a server=master \
-a
location=/backup/AIXLpar -a mk_image=yes \
-a
source=AIX_Lpar_name mksysb_AIX71TL04
Flag
-t
Type
of resource here it is MKSYSB.
Server Specify “master”.
Location Path
on NIM master where AIX_LPAR image will be stored.
source Name of AIX client
(hostname of AIX LPAR)
Mksysb_AIX71TL04 MKSYSB resource
name
5. Create spot from existing MKSYSB resource Mksysb_AIX71TL04.
#nim
-o define -t spot -a source= Mksysb_AIX71TL04 -a server=master -a
location=/export/spot spot_ AIX71TL04
By using MKSYSB resource and SPOT AIX admin can restore AIX client to same AIX level.
Thanks!!!
