I did this on RHEL 5.5. You should have the new drive created and added to the machine before you start anything.First you need to fdisk the drive like any other drive in linux. One key step is that you need to change the type; option ?t? to ?8e? for lvm. root@itsme ~# fdisk /dev/sdc Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel Building a new DOS disklabel. Changes will remain in memory only,until you decide to write them. After that, of course, the previous content won't be recoverable. The number of cylinders for this disk is set to 7832. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite) Command (m for help): n Command action e ex
