Error description
chvg -g can fail for small/big VG if a factor change is required. This can only happen if the VG already has an increased factor value, and chvg -g finds it needs to increase it even more. In that case, it may fail with: -> chvg -g vg00 0516-1381 chvg: Not enough descriptor area space left in this volume group to re-size the physical volumes. 0516-1786 chvg: Convert the volume group to a scalable volume group with the chvg -G command, then retry. 0516-732 chvg: Unable to change volume group
Local fix
Problem summary
For small and big VGs (default MAXPVS of 32 / 128), if MAXPVS is non-default value already, and disks are grown, chvg -g may fail to grow the VG. This can happen due to an incorrect calculation of the new MAXPVS after factor change. . The faulty code uses current factor instead of default factor when calculating new factor, and based on that bad number, may fail a check thinking that it's impossible to increase factor to a large enough value to handle the new disk size when in fact it is possible to do so.
Problem conclusion
Correct logic error in chvg code
Temporary fix
