Use this operation to analyze one or more LVM Volume Groups for possible conversion to VxVM disk groups thus by analyzing the JFS filesystems and LVM volumes present in a Volume Group. This step checks for problems that would prevent the conversion from completing successfully. For example, it calculates the space required to add an LVM Volume Group's disk's to a VxVM disk group and to replace any existing LVM partitions and volumes with VxVM Volume Manager volumes, plexes, and sub-disks. Also calculates the space required for JFS filesystem to be converted to VxFS, if any on the specified Volume Group. For this release, conversion is only allowed for Non-root LVM Volume Groups and unmounted JFS filesystems present on it. Hence, analysis is only allowed on Non-root LVM Volume Groups and an unmounted JFS filesystems. Here are some LVM Volume Group selection examples: listvg: list all LVM Volume Groups list: list all disk devices vg_name: a single LVM Volume Group, named vg_name
