<p class=MsoNormal>1. The server definitely won't boot and I wouldn't expect
either disk to be usable if you put them into the wrong slots.<o:p></o:p></p>

<div>
<p class=MsoNormal>2. Depending on the raid controller settings on the second
server and the hardware between both servers it could do anything from boot
normally to corrupt both disks.<o:p></o:p></p>

<p class=MsoNormal><span lang=NL>Our normal disk swap procedure is<br>
1. power off the server<br>
2. pull disk 1 out<br>
3. if upgrade fails, power off the server again, pull out disk 0, and put disk
1 back to the original tray, power on the server and then put disk 0 back to
tray0<br>
<br>
Curious to know<br>
1. what is going to happen if I pull out both disks and swap the disks, disk1
goes to the slot0, disk0 goes to slot1<br>
1. what is going to happen if I pull out both disks and insert them to another
server<br>
<br>
Thanks in advance.<o:p></o:p></span></p>
