I'm trying to migrate a single disk on a 9650SE 4LPML to a RAID 1. I'm trying to use 3dm2 to accomplish this, but the only options it will allow me to migrate to is either RAID 0 or RAID 10. I only have 2 drives on the controller at the moment, so why it's giving me an option for RAID 10 - I don't know. I also tried doing it through the cards BIOS, but there doesn't seem to be an option to migrate.

Controller Summary

0 9650SE-4LPML L326010B1420305 FE9X 4.08.00.006 2.26.02.012 OK

Drive Information:

0 WDC WD5000AAKX-001CA0 465.76 GB SATA 0 -- 0 OK
1 WDC WD5000AAKX-753CA1 465.76 GB SATA 1 -- -- OK

If it makes any difference:

OS: Ubuntu 10.04 Server / Kernel: 2.6.32-38-server

Anyone have any ideas to get me in the right direction? Thanks.

Edit: Success

Canned 3dm2 and went with tw_cli

//router> /c0/u0 migrate type=raid1 disk=1 Sending migration message to /c0/u0 ... Done.

In hardware controller parlance, RAID-10 is the same as a mirror - except it also allows you to stripe them into RAID-10.

So yes, you want RAID-10; with two disks, this automatically becomes a mirror.

I just gave that a try, and this is the error: (0x0B:0x001A): Invalid number of drives : Failed to start Migrate on unit 01 –  Go3Team Feb 23 '12 at 13:56
    
If the controller has no support to create a degraded array, you need both drives to start with. –  adaptr Feb 23 '12 at 14:06
