    I'm assuming you mean, you want to know what physical hard disk a file
    like: "/etc/hosts" resides on?
    To figure that out find out which filesystem the file is on (considering
    you know the fully qualified pathname of the file "i.e. - /etc/hosts":

    # cd /etc
    # ls -l hosts
    info on hosts file...
    #

    Now check the filesystem you are currently in, the filesystem/directory to
    file lives:

    # df -k .
    /dev/hd4 xx xx xx xx xx /
    #

    Now the directory: "/etc/" which lives on filesystem: "/" which sits on
    logical volume: "/dev/hd4". Now you must find out
    what physical hard disk(s) the "/dev/hd4" logical volume lives on:

    # lslv -l hd4 (hd4 - being the logical volume name):

    PV COPIES IN BAND DISTRIBUTION
    hdisk0 001:000:000 100% 001:000:000:000:000
    hdisk1 001:000:000 100% 001:000:000:000:000

    Under the PV column will be the name of the hdisk the logical volume:
    "hd4" resides on. Then just trace that back to the file in
    the same hierarchy I explained earlier. Now the list of two physical
    volumes/disks means this logical volume is either mirrored
    or is soo big that it spans multiple disks.

    Hope this helps.
    Thanks.

    Is there a command to find out which hdiskXX a particular file belong to?
    thank you in advance ...
