Replace existing disk with larger disk

Mike Prozinski — Mon, 12 Nov 2001 15:34:56 GMT

Hello. Sorry if this question seems too similar to a few I've read here, but I'm hoping someone can give me some advice.

I am planning to replace the existing hard drive on my system with a larger one. I currently have 1 4GB SCSI disk, using logical volumes. I want to replace this disk with a new 18 GB disk, and copy over all of the existing files onto the new disk. I'm wondering what the best way to preceed is. I'm running HP-UX 10.2 and need to do this to several unique systems. All are networked.

Is it possible to use dd to do this? I've cloned the disks before using dd, but always to a disk of the same size. How do I handle the difference in disk capacity?

Should I consider using Ignite? fbackup? tar to tape, then restore? What will I need to do to the volume group configuration after this?

Any advice on how to proceed would be appreciated.

By the way, it generally does NOT help to get responses by posting the question multiple times to multiple groups. In fact it generally just serves to confuse people.

Thanks. Sorry for the cross posting SNAFU. After posting to sys admin, I saw the LVM group and thought that one might have been more appropriate.
