Hi,

you do

lvdisplay -v /dev/vgxx/lvol202 |more

Example:-

--- Logical volumes ---
LV Name /dev/vg00/lvol5
VG Name /dev/vg00
LV Permission read/write
LV Status available/syncd
Mirror copies 1
Consistency Recovery MWC
Schedule parallel
LV Size (Mbytes) 3096
Current LE 387
Allocated PE 774
Stripes 0
Stripe Size (Kbytes) 0
Bad block on
Allocation strict
IO Timeout (Seconds) default

--- Distribution of logical volume ---
PV Name LE on PV PE on PV
----> /dev/dsk/c1t2d0 387 387
---> /dev/dsk/c2t2d0 387 387

after that

iocan -fnC disk --> will show which lun,

Thanks,
Johnson
