    I want to know, is there any way I can find out whether my physical volume is activate or deactivate? For example, I have activate my physical volume group say vg_lvm through "vgchange" command.

    # vgchange -a Y vg_lvm

    Now, how I will know that "vg_lvm" is activate? Is there any way to query or is any config file changes by executing above command? So that I can look for that file or any sorts of command available? Below I have shown the output of vgdisplay command. How to find out from that my vol group is active / deactive?

    [[email protected] ~]# vgdisplay -A
    --- Volume group ---
    VG Name vg_lvm
    System ID
    Format lvm2
    Metadata Areas 2
    Metadata Sequence No 2
    VG Access read/write
    VG Status resizable
    MAX LV 0
    Cur LV 1
    Open LV 0
    Max PV 0
    Cur PV 2
    Act PV 2
    VG Size 1.12 GB
    PE Size 4.00 MB
    Total PE 288
    Alloc PE / Size 25 / 100.00 MB
    Free PE / Size 263 / 1.03 GB
    VG UUID ci9mLc-JuVk-pUBV-gtYd-T9F2-LxsC-uLXGcb

    The Opearating System I am using is RHEL 4. Please help me in finding the solutions.

    If it's listed by vgdisplay, it's active.

    Thanks for your reply. Even for a deactivated volume group, vgdisplay also shows the same attribute. I have deactivated thru command:

    vgchange -a n vg_lvm

    and execute the vgdisplay command and it displays the same results like vol group activate. IS there is any other way to find out?
