    well, it isnt possible with chfs but if you use extendlv you can specify
    the hdisk to be used

    Since the FS fs01 is created on hdisk1 and once I set the inter-alloc
    policy to min, I understand that as long hdisk1 has free space, the
    file system uses the space on hdisk1 only, but if fs01 has to extend
    beyond hdisk1 then you want me to add 1 pp of hdisk2 to the file system
    fs01 and set upperbound to 2. But I dont think while increasing the file
    system I can specify PP of which disk has to be used. If this is
    possible my problem is solved.

            Hi Andy,
             
                To put it short,I would like to know the following info.
             
            I have a FS fs01 of size 5GB on an LV that has been created on
    hdisk1 which is of 18GB. This PV belongs to a vg called dbvg, which has
    5 other disks which have a lot of free space. Now my question is if I
    increase the file system fs01 to 20GB, from which disk does the system
    pickup the excess 2GB space required for this file system. Is this
    random or can I make a choice saying please pickup only from hdisk2 ?
             
            I have tried all the below commands except migratepv before
    putting it in the forum, but of no use.
             
            I hope you have got my requirement.
             
            TIA
            Praveen

                    Hi,
                    
                        Sorry, I cannot understand your words, but I do
    think that the following command should be useful:
                    df
                    lslv -m lvname
                    lspv -l lvname
                    migratepv
