I just talked with someone about a similar situation. HP-UX server running 2 72G mirrored drives and had one fail. The vendor subbed a 146G drive. In this case it would rebuild to only 72G of the 146 drive, but the vendor said that if the other 72 drive failed and was replaced with the 146 then I could extend it to the full 146 at that point. I have not tested this, and am not sure if it would work, but wondering if you could replace the drives one at a time allowing for the rebuild. I did something similar with a EVA SAN and was successful. It took a long time, but I didn't have to take the system down. I'm not sure I'd risk it on a production system. Can you do a system level backup/restore?

Need to replace the drives with (4) 2TB sas drives in a RAID5 array. Server only holds 4 physical HD bays so I can't just add an extra array. Curious if anyone has any tricks to speeding up this migration other than rebuilding the OS from scratch on the (4) new 2Tb sas drives and reinstalling all the apps on the server, etc. JR
