The relationship of factor -t, PP numbers per physical disk, and the number of disks allowed in one VG is provided in Table 19. Table 19. Factor -t Factor t PP numbers Number of disks in VG 1 1016 32 2 2032 16 3 3048 10 4 4064 8 5 5080 6 6 6096 5 7 7112 4 8 8128 4 16 16256 2 Following is an example of a 4.3 GB disk. The PP size 8 MB is needed for creating the volume group vg1 without the factor -t: # lsvg vg1 VOLUME GROUP: vg1 VG IDENTIFIER:00091974e54218d7 VG STATE: active PP SIZE: 8 megabyte(s) VG PERMISSION: read/write TOTAL PPs: 537 (4296 megabytes) MAX LVs: 256 FREE PPs: 537 (4296 megabytes) LVs: 0 USED PPs: 0 (0 megabytes) OPEN LVs: 0 QUORUM: 2 TOTAL PVs: 1 VG DESCRIPTORS: 2 STALE PVs: 0 STALE PPs: 0 ACTIVE PVs: 1 AUTO ON: yes MAX PPs per PV: 1016 MAX PVs: 32 When using the factor -t to create vg1, the PP size of 4 MB can be used. Then, the maximum PPs per physical volume becomes 2032, and the maximum physical volumes allowed in the volume group is 16. Following is an example: # mkvg -t 2 -y vg1 hdisk4 0516-1193 mkvg: WARNING, once this operation is completed, volume group vg1 cannot be imported into AIX 430 or lower versions. Continue (y/n) ? y 0516-631 mkvg: Warning, all data belonging to physical volume hdisk4 will be destroyed. mkvg: Do you wish to continue? y(es) n(o)? y vg1 # lsvg vg1 VOLUME GROUP: vg1 VG IDENTIFIER: 00091974e54743e9 VG STATE: active PP SIZE: 4 megabyte(s) VG PERMISSION: read/write TOTAL PPs: 1075 (4300 megabytes) MAX LVs: 256 FREE PPs: 1075 (4300 megabytes) LVs: 0 USED PPs: 0 (0 megabytes) OPEN LVs: 0 QUORUM: 2 TOTAL PVs: 1 VG DESCRIPTORS: 2 STALE PVs: 0 STALE PPs: 0 86 AIX Version 4.3 Differences Guide
ACTIVE PVs: 1 AUTO ON: yes MAX PPs per PV: 2032 MAX PVs: 16 Note When using the -t flag with chvg and mkvg, it must be entered from the command line. 5.5 Physical Partition Support (4.3.1) The support for physical partition sizes of 512 MB and 1024 MB have been added to AIX 4.3.1. Volume groups created with this new size cannot be imported into previous versions of AIX. In pre-AIX 4.3.1 versions, if you add a new volume group, the physical partition sizes in megabytes you are allowed to chose are: 1, 2, 4, 8, 16, 32, 64, 128, and 256. For AIX 4.3.1, and later releases, if you add a new volume group, the physical partition sizes in megabytes you are allowed to chose are: 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, and 1024 MBs. If you select a physical partition size of 512 or 1024 MBs on a AIX 4.3.1 or later system, the volume group created cannot be imported on older versions of AIX. 5.6 Big Volume Groups (4.3.2) Table 20. Limitations of LVM A new volume group (VG) format is added in AIX 4.3.2, which increases the maximum number of disks that can be included in a volume group from 32 to 128. The maximum number of logical volumes in this new volume group format is increased from 256 to 512. This means: • The maximum physical volume (PV) number in one volume group is increased from 32 to 128 (1024 in the future) • The maximum logical volume (LV) number in one volume group is increased from 256 to 512 (1024 in the future) Table 20 provides information about LVM restrictions in several AIX versions.
