For someone who can't even seem to figure out something as simple as assigning points to reward the people that attempt to help you, you sure seem to have a lot of questions.

What are you studying for?

Hi Binu,

First you create a LV with 0 bytes.

#lvcreate -n lvdata vg01

Now extend the LV onto a certain disk:

# lvextend -L 500 /dev/vg01/lvdata /dev/dsk/c4t2d0

SYNOPSIS

/usr/sbin/lvextend [-A autobackup] {-l le_number | -L lv_size | -m mirror_copies} lv_path [pv_path ... | pvg_name ...]

I believe this is clear..

So you're studying for your next interview. I really don't see this as being any different than mis-using the Forums to answer exam questions. You're taking up the time of people who are here simply to try and help others with their technical problems, you're cluttering the Forums with trivial questions, and you are unable to even extend the courtesy of rewarding people's efforts in your behalf by assigning a few lousy points.

Just my opinion.
