I am new to being a Unix admin and have a question about replacing some hardware. I have a K class box using HP-UX 10.20 with three disks. Two of the drives are in one logical volume. Every 3 or 4 days, the syslog is showing that one of these drives is experiencing "POWERFAILED" and then recovering a few seconds or minutes later. My manager feels that the drive should be replaced.

From reading the documentation, it seems to me that I can shutdown, replace the one drive that is failing, and then restore the whole logical volume. Do I need to re-create the logical volume before doing a restore? Are there any other steps I need to take when replacing only 1 drive when the volume group and logical volume encompasses 2 drives?

Thank you in advance for any help.
