Solution 


Change the configuration file /var/adm/ras/liveupdate/lvupdate.data disks details to free disks available in the lpar and not part of any logical volume


# cat /var/adm/ras/liveupdate/lvupdate.data

general:

        kext_check = 

disks:

        nhdisk  = hdisk2

        mhdisk  = hdisk3

        tohdisk = hdisk4

        tshdisk = hdisk5

hmc:

        lpar_id  = 

        management_console = hmc_full_qualified_domain_name

        user = hscroot


Run the LKU preview with the free disks
