If the diskgroup SYSTEMDG is not mounting (because of multiple disk failures) then following procedure can be used to recreate this diskgroup.
Sometimes if one of the disk is missing then diskgroup will not mount and will give error regarding missing disk but if all other members are available then we can mount the diskgroup with FORCE option and later drop the missing disk. Once the disk is replaced we can add this missing disk again to diskgroup.
