Hi Ankit:

Why not use?

# symvg show vgec2

Thanks James for replying

Thats fine me & helped me.

But for leaing purpose i can now extact vgec2a info using sed or awk if i paste this info in file.

We might have other situations where command is not available.

Perhaps something like this:
awk -v dev=vgec2 '
BEGIN { found = 0 }
$1 == "Volume" {
if ($NF == "/dev/" dev)
found = 1
else
found = 0
}
found { print $0 }' file

Oops, if it isn't obvious, "dev" is set to what VG you want to list:
awk -v dev=vgec2a '
