    -----BEGIN PGP SIGNED MESSAGE-----

    Thanks to Kevin O'Donovan

    He sudgested running a disk info which showed the disk to be there and then I
    did a pgcreate on the device which bombed out.

    The next attack was reseating the fibre-channel cards which seemed to the
    trick with everything a. ok.

    - ---- ORIGINAL QUESTION------

    Hi all

    I am tring to add a 60gb san device to an lvm group but when I seem to do
    this
    I seem to get the following messages when I either create a new disk group
    or
    adding the device via the vgcreate command.

    vgextend command to an existing disk group.

    vgextend /dev/sybdump /dev/dsk/c16t0d5
    vgextend: IO error on Physical Volume device /dev/dsk/c16t0d5:

    When trying to create a new diskgroup with the same device

    vgcreate -l 12 -s 8 /dev/test /dev/dsk/c16t0d5
    Physical Extent Size changed to 0 MB to accomodate smallest physical volume.
    Floating point exception (core dumped)

    and yet all the paths look correct. and connected. I have also tried
    reconfiguring the device on the san all to no avail.

    San Array HSV110

    Hp secure Path used.

    OS version 11.iv2

    Any Ideas???

    Thanks in advance -greg
