Enter the lsvg command to view the VG list in the current operating system. A vg consists of at least one pv, and a pv can only be in one VG at most. PP --- in a vg, the disk is divided into a uniform pp size. Enter the command lsvg rootvg to see that rootvg is composed of multiple pp, and the sum of the pp is the physical size of the PP. Logical partitions and physical partitions. logical partitions can correspond to one or three physical partitions. A logical partition can be a cross-region (physical partition ). Manually specified. Use lsdev-Cc disk to view available disks of the current system. Use lsvg-p rootvg to view which hdisks are contained in a vg.
