One volume group was only setup "VolGroup00"

Hello,

Firstly, please answer these two questions:

1. what do you see with this command:

# fdisk -l

2. How many volume groups do you have? (you can find this information
With the following command. The -v flag will give more verbose output including the logical volumes associated with each volume group):

# vgdisplay -v

Subject: Adding new disk to volume group

Currently I'm using Red Hat Enterprise 4 that has two disk on a Hardware
Raid 1 (Smart Array 5i controller) that is setup in a Volume Group
(VolGroup00) with the following logical volumes LogVol00, LogVol01, LogVol02, LogVol03, LogVol04, and LogVol05. I recently added two more

disks in our system/server (these are internal disks on a HP Proliant
DL380 g2) and set these disk as a Hardware Raid 1. Now I haven't used
Fdisk or nothing on these new disks.

Here's my question: How do I add the new disks to the already existing
Volume Group so that I can have more space on the Volume Group. Being a
Raid1 I know your only adding one disk. Could someone send me the exact
commands to use?
