APAR status

  • Closed as program error.

Error description

  • cplv command is failing while trying to copy from a 512
    block disk to 4k block disk.
    
    /usr/sbin/cplv -v vg4k -y fslv02 fslv01
    copyrawlv: Invalid argument
    0516-743 cplv: Error occurred during data copy.
    

Local fix

Problem summary

  • cplv may fail if copying an LV without an lvcb on disk but with
    a filesystem from a VG with 512b block size to one with 4k
    block size.  Typically this would be using SVG type VGs.
    

Problem conclusion

  • Correct cplv code wrt to how much it skips during cplv so that
    we ensure we only write in 4k chunks to the destination LV, as
    writing less than that is unacceptable in a 4k bs VG.
    

Temporary fix
