I'd like to see how my database datafiles are distributed across disk controllers and disks.
How can I map the logical drive to the actual physical device?

example:
 bdf .
Filesystem          kbytes    used   avail %used Mounted on
/dev/vg17/lvol1    28446720 27592720  840716   97% /u42

The directory is on the /dev/vg17/lvol1 logical volume.
I'd like to know how to map this volume to an actual physical disk in /dev/dsk ?

***Please keep in mind I do not have superuser access.  I am a DBA and I'd rather not trouble
the admin group if I can do it myself.

lvdisplay -v dev/vg17/lvol1
(LVM "display" commands should work for any user)

The first section of the output will list the physical disks the Logical Volume uses; The "-v" option shows the detail of the layout of Logical Extents (Think of them as "blocks" for this exercise) on the Physical Extents of the disks
