Combine 2 logical raid 0 drives to 1 logical raid 1 drive

fault-tolerancehphp-smart-arrayraid

I have an HP Proliant server with an P410i embedded array controller.

The server was originally setup with 6 physical drives with the OS on 1 logical drive with a raid 0 and 5 physical drives setup as a raid 5. Not the way I would have done it but is what it is. Well, we got an expected drive failure on the OS drive. The network admin at the time could not add a drive to the hardware array so he mirrored the drive in disk management using software mirror. Lo and behold the OS drive has finally failed.

I found out the hard way that a software mirror does not mirror the boot sector. So I was able to make a bootable disk and get the server back up and running on the mirrored drive that is still good. So now I am at the point of getting fault tolerance setup back up and would rather do a hardware array.

So in my Array Management right now I show 3 logical drives. 2 Logical drives are showing as seperate arrays of 1 physical drive running raid 0. I am trying to find a way if possible to convert these two Raid 0 drives into one logical Raid 1 drive without losing any data since this the operating system drive.

If I can get these two Raid 0 drives into 1 logical Raid 1 drive I believe I can recreate the MBR then and make them bootable as well.

Any help or suggestion on how to combine the arrays woulbe appreciated.

You can add a disk to an existing array.

In this case, you probably want to delete whatever is on Array C. Add that drive to Array A.

If you do so, the fault-tolerance level of logicaldrive 1 should become RAID 1.

The GUI utility will be easiest for you... but the CLI process will be something like:

controller slot=0 array C delete forced

The add command adds a physical drive or spare to the specified array or logical drive. Adding physical drives is the same as expanding an array.

controller slot=0 array A add drives=1I:1:1

modify [raid=0|1|1adm|1+0|1+0adm|5|50|6|60|?] [stripsize=8|16|32|64|128|256|512|1024|default|?] Migrates the specified logical drive to the desired raid level and/or strip size. The implied units of stripsize are KB. The target can be any valid logical drive.

controller slot=0 logicaldrive 1 modify raid=1 stripsize=default
