Adding Another RAID 1 Volume - Have Two Already - Don't Want to Mess Up

I have four HDs. Two are in a RAID1 volume and have my OS. The other two are RAID 1 volume and for storgae. I'v now added another two (total six HDs now) that I also want to create a RAID 1 volume for.

 

Here's the question.

 

When I'm in Intel Matrix Storage Manager I choose "Create RAID Volume"

 

I then give it a name and select RAID 1 as the level.

 

Then it wants to create the volume.

 

BUT, it doesn't tell me/ask me which HDs it going to do this with.

 

Can I ssume it is using the only two unassigned HDs available and that's why it's not asking me?

 

My logical brain says "yes", my paranoid brain says " I hope so but what if?.....".

 

Can I safely create the volume knowing there is no chance it will touch my current RAID volumes and only use the unassigned drives?

 

Thanks.

    The step after that should be selecting the hard drives - see the image on page 47 of the User's Manual - PDF at http://www.intel.com/support/chipsets/imsm/sb/cs-020670.htm

     

    That chapter walks you through all the steps you should be seeing

    Ahh. I didn't know there was a utility I could manage my raids with from the desktop. I was accessing the one that comes with the motherboard and you access through CTR+I during post in the boot cycle. That one has a very minimum UI. I downloaded the utility you mentioned and it makes a lot more sense now.

     

    Thanks.

    Hi Dan_O

     

    I have the same problem. I have a solid state drive as my boot and 2 1TB drives as raid 1. I have set this up in 'Computer Management' and everthing seems to be fine - The disks show as Mirrored.

     

    But when I Boot I get the Intel Storage Manager flashes up and I can see that it says the 2 1TB drives are Non-Raid. Obviously I can set the drives up in storage manager but will I loose all the info on my 1TB disks?

     

    Any info would be wonderful...

    I'd have to double-check the User Guide, but I'm pretty sure one of the RAID 1 options is "Build from existing".

    You can safely break apart a RAID1 array and both disks will be bootable and usable. To put a RAID one back together you select one to be the source and the other to be the "build to" drive. That's not the exact terminology used in the Matrix but it's pretty close. They'll be several warnings telling you exactly what is going to happen before you accept the choices. I was trying to install Windows 7 on a fresh RAID 1 array with two 1TB drives and was getting endless errors. So I broke apart the RAID, wiped them clean, and installed successfully to one. Then I recreated the RAID 1 array using the fresh OS drive as the source and the blank as the built to. After letting it ride forr 24 hours it could still not rebuild the array and was stuck at 1%. I broke apart the array again and wiped the free disc clean and started getting errors when trying to reformat. I determined it was a bad drive, bought a new one, and then recreated the volume (with the good OS drive as the source) and have had no issues since. So the lesson is:

     

    1. You can safely break apart RAID 1 arrays without loss of data to either drive ( I was booting to one of the drives successfully through the whole process)

    2. You can take any existing drive and use it as a source to build a new array without any loss of data on the source drive.

     

    I wish I took screenshots and notes through the proccess but it was pretty simple and you can only create RAID arrays from free drives. So if you have two available those will be the ones Matrix will allow you to choose from. If there aren't two drives free you will get an error telling you you don't have any drives available, so no need to worry about accidentally destroying any other functioning arrays.
