I have a 206m 8485-1AU server with 2 160GB simple swap disk drives configured as raid-1 using serial ATA controller. Both drives are experiencing failures and would like to swap drives for 4 500GB disk drives p/n 39m4533. Is there a way to accomplish this without reloading the entire server?

How do you plan to raid the 4 disks?
You can use a product like acronis server edition to clone from the mirror to the new array.

Is the server still running since you mention that both drives are experiencing failures?
system is functional drive failures are intermitttent, as for dirve setup still not sure. Could I install 2 500gb Raid 1 drives in the empty slots and restore Acronis image to new drive set and make bootlle to test, if system does not work return system to proir state. Customer is online 6 days a week so their is little room for error.
I would get two 160's and configure them as hot spares and then fail the going bad drives one at a time over to the hot spare.
configuring the drives as hot spares is like 10 minutes. Failover will slow the system down a bit but remain operational.
Point here is doing a drive upgrade when dealing with imminent failure is not a good plan.

Thanks for the info, customer wants to increase disk capacity can I install a larger drive as a hot spare in the same manner?
I believe I have a simple swap disk drive bay, will this allow configuration of a hot swap disk drive?
How many bays total in this unit?
I have never met a raid controller that couldn't do hot spare. this is a function of the controller not the bay.
You do not want to use the larger drive for hot spare. You will only get 160gig of a 500gig drive with a failover.
Great to increase disk space but this isn't the time to do so. Your client has a crisis on his hands and every hour that goes by puts him closer to total failure. Procrastination is death in this case.
The best config would be to have the OS on the new 160gig and data on the mirrored 500gig drives with a 500gig drive as a global failover. If a 160 failed over to the 500 you would just get another 160 and fail the 500 back over to it and then set the 500 as hot spare again. This way your data and OS are both not in the same basket so to speak.
