Prepare VIOS for the LPAR

Total 6 internal disks. not SAN/storage. So I prefer mirror the rootvg as well as VIOS. Here are the steps:

# lsvg
rootvg
VIOS

# lspv
hdisk0          none                                None          
hdisk1          00f92e0cb02e0057                    VIOS            active
hdisk2          00f92e0c5334bc72                    rootvg          active
hdisk3          none                                None

# mirrorvg rootvg

0516-1126 mirrorvg: rootvg successfully mirrored, user should perform
        bosboot of system to initialize boot records.  Then, user must modify
        bootlist to include:  hdisk2 hdisk0.
