    how many hard disks i have? one ( pci@85,2000 ) ? Or 12
    ( c4t0d[1,2,6-15] )??

    With EMC^2 it's a little difficult to tell. You can count the logical
    drives that the box presents to you. How many physical disks is a
    question you would have to put to EMC^2.

    The only EMC^2 array that I'm at all familiar with is the 3630. That
    had 36 GB disks to start with and, later, some 50 GB disks. The logical
    drives presented by the box were 8 GB each.

    Given the tiny size of disk 2 (c4t0d0) I'd suspect that's a
    gatekeeper, so it might be worth checking whether symcli is installed
    (probably in /opt/emc). That might be able to get you more detailed
    physical information.

    Or some number in between.

    One thing to do is to look at the WWNs of the devices you're seeing.
    This will at least tell you whether you are seeing the same object
    down multiple paths (I suspect that, here, you are not, but who
    knows).

    Given that this is presumably storage on an EMC SAN you probably will
    never be able to tell how many actual physical spindles you have, of
    course: I presume what you're interested in is how many distinct LUNs
    it is exposing to you.
