Closed as program error.
Error description
chvg -g on scalable and mirror pool VGs can fail with # chvg -g VGName 0516-058 lchangevg: Not enough memory available now. Try again later 0516-732 chvg: Unable to change volume group VGName if the VG has 29 or more hdisks
Local fix
set maxdata for lchangevg to a higher value This may work for VGs with up to 56 disks only, because lchangevg is a 32bit binary and memory it can address has a limit.
Problem summary
LVM is not freeing memory when it should, so chvg -g can fail if there are enough disks and large enough metadata being written.
Problem conclusion
Free memory properly.
Temporary fix
