I have a voice mail system based on Unix. The drive is noisy and seems to be dropping data. I have another drive.
Old Drive is 2 gig Wide SCSI. New Drive is 3 gig wide scsi.
How can I do this?

I think it is possible with third party cloning tools such as Norton Ghost. They clone drives regardless or partition or file system.

On that server acting as your voice mail server, simply install the new drive, create the new partition the same location as the original one with a bigger size, mount that new disk, copy the old disk on the new one using *ufsdump, modify your *vfstab so your new drive is mounted as the new one, *mount -a... Is that disk also your boot disk? If yes, you have to install a boot block on it. That part is quite different depending on the o/s.

(* That command or file might be different depending on the o/s)

Hope this help!

!!! dd with care !!!

Get it wrong and kiss the system good-bye.

Need more info to properly guide you through it all but generally:

Drop in new disk, partition it, unmount the old disk, mount the new disk in its place, mount the old disk temporarily somewheres, use favourite copying tool to move the data across, check all is well, ensure the mount is permanent over the next boot, back the baby up and scrap the old disk.

o'course if its a one disk system or its the acting boot disk you have more grief...

How depends on which UNIX rocks your world.
