    The error's pretty clear. Someone created a volume group, used the default PP size, and now you're trying to add a new disk which will result in too many PP's using that PP size.

    You either need to change the factor on the volume group (which the error tells you how to do), or migrate it to a scaleable volume group assuming it's AIX 5.3.

    man chvg

    In future, I recommend either using PP sizes which will support larger disks later on, or using scaleable volume groups.

    dear aix guru,
    can i change vg to scaleable vg on the fly? what do u mean by migrate to scaleable vg? our os is aix 5.3.
    this is database vg, normally we will choose big vg. can we use scaleable vg for database?
    i issue this command #chvg -t 3 vg03. then i'm able to extend the vg.

    The error's pretty clear. Someone created a volume group, used the default PP size, and now you're trying to add a new disk which will result in too many PP's using that PP size.
    how the calculation is derived from?
    PP SIZE: 8 megabyte(s)
    TOTAL PPs: 382 (3056 megabytes)
    MAX PPs per VG: 130048
    MAX PPs per PV: 1016 MAX PVs: 128
    can u teach how aix calculate that i'm trying to add new disk that result too many PPs using that PP size. will take note, i'll create the vg of PP of 256GB in size.
    hope to hear from you. thank you
