Validating live update input data.
Computing the estimated time for the live update operation:
-------------------------------------------------------
LPAR: aix78
Blackout_time(s): 20
Global_time(s): 950
Checking mirror vg device size:
------------------------------------------
Required device size: 13888 MB
Given device size: 51199 MB
PASSED: device size is sufficient.
Checking new root vg device size:
