    I am taking mksysb from the system where the rootvg is mirrored.
    Will this backup will have the mirrorvg data also?
    Will it make any affect on the new machine while installing?
    Will it ask for the additional disk to mirror? or
    Will it install the OS as it is on mksysb?

    The backup has the complete definition of rootvg, including mirroring definitions. Doesn't store duplicated data because it is not needed (it's identical in both copies). You will need two disks to install that backup image, and it WILL FAIL if you give only one disk to install to. It will install the same than original, identical version, identical files, identical dates and attributes, identical configuration.

    Thank you. I have one more doubt.
    If I am having rootvg on local disk and that is mirrored with the disk on SAN. How to make the local disk to SAN without any impact.

    Hello. Storage in AIX is not easy in concepts, but IT IS easy to manage.

    If you have rootvg with local hdisk0 and external hdisk1, you can select another FREE disk in any drawer (internal and/or external) and:
    Grow your rootvg -- extendvg rootvg hdiskZ -- with hdiskZ your "new" disk
    Migrate your disk contents -- migratepv hdisk0 hdiskZ -- putting all contents from hdisk0 in hdiskZ, with these online, and being used
    Migrate your boot -- bosboot -a
    Migrate your boot selection (in the firmware of server or server VM) -- bootlist -m normal -o hdisk1 hdiskZ
    Clean your "old" OS disk -- reducevg rootvg hdisk1 ; chpv -c hdisk0
    DONE
