Next I'm trying to setup a raid-10 logical volume.

Got the two mirrors built.
Now I need to stripe them

Here's an excerpt from -LDPDInfo
I just added a little white space it makes the output much more readable.
And I deleted the stuff about other Logical Drives

+ /home/drew/bin/MegaCli -CfgSpanAdd -R10 -Array0[11:3,11:4]
-Array1[11:5,11:6] -a0

Drives are not consistent with Disk Group.

Doesn't look like it liked the way I specified the mirrors!

MegaCli –CfgSpanAdd -aN|-a0,1,2|-aALL -R10|-R50|R60 –
Array0[E0:S0,E1:S1,...] –Array1[E0:S0,E1:S1,...] [...] [WT | WB]
[NORA | RA | ADRA] [Direct | Cached] [CachedBadBBU|NoCachedBadBBU] [-
szXXXXXXXX [-szYYYYYYYY [... ]]] [-strpszM] [–afterLdX] -aN

Hmm.  The -aN|-a0,1,2|-aALL part looks completely bogus

The Arrays look right to me.
Will set some different polices, etc after I get this part working!
