A logical volume is not necessarily associated with
a single disc as in most cases people tend to
mirror/stripe a volume group across many disks
before creating logical volumes in the volume
group.
However, if you execute
vgdisplay -v /dev/vg00
then the tail end of the report will show you the
list of physical volumes (i.e. discs) associated
with the volume group.
PV Name /dev/dsk/c0t5d0
PV Status available
Total PE 2169
Free PE 1328
Autoswitch On
You will also get a list of the logical volumes
in the volume group
LV Name /dev/vg00/lvol3
LV Status available/syncd
LV Size (Mbytes) 140
Current LE 35
Allocated PE 35
Used PV 1
If you want to track down extreme levels of detail,
you can issue:
lvdisplay -v /dev/vg00/lvol3
Amongst other things, this will tell you how much
of that logical volume is on each physical volume
of the volume group
--- Distribution of logical volume ---

|Hello all,
|
|If I want to know from the unix system point of view, which disk is
being bombarded by a particular data file, how do I come to know. I
have used the mount command but that gives me the logical volume, but
does not give the disk name that it is hitting.
|
|This is on hp11. I can come to know from the mount command that
oracle datafiles are on /dev/vg00/lvol3
|
|But I want to know which disk does /dev/vg00/lvol3 hit? whether it
hits disk c1t2d0 or c2t2d0 ?
|
|Any unix guru can tell me what command to see apart from mount which
I have used?
|
|thanks.
|
