I am writing a shell script to get the status of the logical volumes on an HP server. The command that I am using is lvdisplay, and it produces the following output:
$ lvdisplay /dev/vg00/lvol3
--- Logical volumes ---
LV Name                     /dev/vg00/lvol3
VG Name                     /dev/vg00
LV Permission               read/write
LV Status                   available/syncd
Mirror copies               1
Consistency Recovery        MWC
Schedule                    parallel
LV Size (Mbytes)            200
Current LE                  50
Allocated PE                100
Stripes                     0
Stripe Size (Kbytes)        0
Bad block                   off
Allocation                  strict/contiguous
IO Timeout (Seconds)        default

The above is more info than I really need. What I would like to get this to look like is the following:
LV Name                     /dev/vg00/lvol3
LV Status                   available/syncd
Mirror copies               1

My attempt at this is to pipe the output of the lvdisplay into a perl command line program as follows:
lvdisplay /dev/vg00/lvol3 |perl -a -n -F'\n' -e'print "$F[1]\n$F[4]\n$
+F[5]\n";'

Any ideas as to how I might accomplish this?
