In your set-up where you have only one volume, then you could argue that the second controller is unnecessary. However, if you have several volumes, then these can be shared evenly across the two controllers.

Is this a new machine?
Or a working one that has stopped?
Is this message from the RAID controller during boot, or when attempting to install the operating system
What RAID controller are you using? What disks are you using?
For example, the on-board RAID controller does not support SAS disk.

Can you see the Operating System on the shared port?

Are you using a Memory Stick for the Status Media (first screen when Server Start boots)? If not, using one may resolve your problem.

I'm no expert - but don't you need to get the serial connection going to type in commands?

If the replacement is a new disk, then it should just be a case of using it to replace the failed. Assuming auto-rebuild hasn't been disabled, in should automatically be picked up. Best to check in the RAID Manager to make sure. If he disk has been previously used, then the RAID controller may refus...

I don't think that deleting an array will delete your data. Normally it is when you build an array and the array gets initialised that any data on the disks get deleted. If you create an array with exactly the same parameters as on the previous system and ensure that it is not initialised (check the...

Have you tried deinstallating ServerView Raid Manager and then installing the latest version ?

A RAID-1 (mirror) will protect your user data against single disk failure. So they can continue accessing their data whilst you get the failed disk replaced. If you just have their data on a single disk and it fails, then they will have lost anything that has changed since the last backup. You are d...

If you have a RAID controller on the server, then it will not simply make the disk available to Windows. Do you have an application call ServerView RAID Manager installed? This will show the RAID configuration and allow you to make the disk available (unRAIDed ?) to Windows. Additionally what size d...

Did you get the driver off the Fujitsu Technology Solutions downloads website http://ts.fujitsu.com/support/downloads.html ? The Econel normally uses the RAID controller on the motherboard. Do you get a name like "LSI Embedded MegaRAID"

Have you checked the ScreenSaver settings? Do you have to power it off with the button to recover?

Do you have ServerView Agents installed? If so have a look at the System Configuration Utility - it has a section on automatic power off. I believe that if this gets enabled the default is mid-night. Also, if you are running Windows, worth checking the event logs for entries around the time of shutd...

Well, you can't do anything with the disks until they are inserted into the SX60!

When you come to create the VDISK, you will need to specify the HDDs you want to be included (so they need to be already seen by the SX60) and you will need to specify the RAID level (persumably RAID 1).

Try http://support.ts.fujitsu.com/Manuals/ShowDescription_KMT.asp?DokuID=214441. Login into the GUI as Manager, and create a VDISK to define the RAID arrangement for the physical disks. Then create a VOLUME on the VDISK and finally MAP the volumes out to the HOSTS.
