I have an M5015 controller in an x3650M3 server.  I have 2 existing RAID1 volumes.  I am trying to add 4 new disks and convert the 2 arrays to RAID10.  According to the doc I find on this controller, it supports RLM without a reboot (a reboot is fine, that's not my problem).  I am not getting an option in WeBIOS to add/stripe the new RAID1 arrays to the existing RAID1 arrays.

here is one link that indicates it should be possible - http://www.redbooks.ibm.com/abstracts/tips0738.html

Existing:
2 x 146g - RAID1
2 x 600g - RAID1

New:
2 x 146 + 2 x 146 - RAID10
2 x 600 + 2 x 600 - RAID10

I have installed the 4 new disks.  In WeBIOS, I can create a R1 array, but at the point where you can create a R10 span, it does not show the existing R1 array.

I don't know of any controller that supports reconfiguring to a multilevel  raid without data loss. Many support going from 0 or 1 to 5 or 6 but not to 10 or 50. What you'll need to do is backup the data(maybe take an image), wipe the current config, create the new arrays then restore from backup. I don't have personal experience with that specific controller
