Creating AIX mksysb ISO bootable image

    

Run mksysb command 

lpar1 # mksysb -X -i -e /mksysb/lpar1/lpar1_23jul12.mksysb ⤶      

If for any reason necessary, you can create a bootable DVD.iso file from a mksysb backup, using mkcd:

mkcd -L -S -I /mksysb/bootable_mk -m /mksysb/my_mksysb_backup

Where:

-m for, Specify previously taken mksysb

-I for,  Specify directory where the bootable DVD iso will be placed

-S for,  Do not write to DVD media/device

Now Create a bootable iso image from this mksysb image :

lpar1 #mkdvd -S -m /mksysb/lpar1/lpar1_23jun12.mksysb ⤶

This will create a new filesystem /mkcd/cd_mages and store the bootable iso image there.

lpar1 # cd /mkcd/cd_images ⤶   

lpar1 # ls –ltr ⤶   

total 4239112  

drwxrwx---    2 root     system          512 Aug 01 11:57 lost+found

-rw-r--r--    1 root     sys      2170353664 Aug 01 11:57 cd_image_483704 

lpar1 #

 Lets Check the size of the image

lpar1(/mkcd/cd_images)# du -gs * ⤶  

2.02    cd_image_483704   

lpar1(/mkcd/cd_images)#

Rename this image to relevent name, In my case, it is..

lpar1(/mkcd/cd_images)# mv cd_image_483704 lpar1_23jul.mksysb_bootable ⤶

lpar1(/mkcd/cd_images)# du -gs * ⤶

2.02    lpar1_23jul.mksysb_bootable 

lpar1(/mkcd/cd_images)#   

Now get this image through FTP in windows and burn on DVD. After buring to DVD, you can use this bootable DVD to restore the server.
