Remaining Space After Mirroring

My HP9000 has 10 disks of 9.1 GB each.
With help of the fpmurphy (thank you) it is knowing that 8 of them are mirrored (using lvdisplay).
What should i do to know which is the existent free space after mirroring.

Regards

To find the free space in, say vg00, use the command:
vgdisplay vg00
and look at the line labeled "Free PE".

To find the free space on a particular physical volume, say /dev/dsk/c1t2d0, use the command:
pvdisplay /dev/dsk/c1t2d0
and again look at the "Free PE" line.
