    we're planning on doing this with flashcopy on a fastt unit, and have experimented, but no production code...using recreatevg does not give us an error on subsequent runs. the fastt software comes with a utility called SMdevices which lists the hdisk to logical disk relationship...we're parsing that output for the hdisk to feed recreatevg.

    Subject: ESS Flashcopy question

    I am trying to automate the establishing of flashcopies. I do the following commands in a shell script:
     
    umount filesystems
     
    varyoffvg volume groups
     
    exportvg volume groups
     
    execute flashcopy tasks
     
    importvg volume groups virtual path
     
    varyonvg volume groups
     
    mount filesystems

     
    This works great the 1st time. On subsequent times, the importvg fails with
     
    0516-304 getlvodm: Unable to find device id ...
    ...
     
     
    This is a P630 running AIX 5.1. Reading documentation, it appears I could use recreatevg instead of importvg, but it requires the hdisk values.
     
    Question: Should I use recreatevg or importvg? Advantages/disadvantages?
     
    Thanks for your help,
    Gene
