APAR status

  • 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
