Using hpacucli to mirror drives across MDS600 drawers

[Adam Garsha]

How can I create a raid 1+0 group that mirrors drives across my two mds600 drawers using hpacucli?

Namely, I am not sure how to specify that the mirrors should for example be:

M1 == 51:1:1 mirrors 53:1:1
M2 == 51:1:2 mirrors 53:1:2
...
M8 == 51:1:8 mirrors 53:1:8

and then stripe across all M1->M8?

I want to avoid having mirrors in same drawer of mds, so I don't want any: 51:1:1 mirrors 51:*:*.

My unassigned drives looks like so:

physicaldrive 51:1:1 (port 51:box 1:bay 1, SAS, 2 TB, OK)
physicaldrive 51:1:2 (port 51:box 1:bay 2, SAS, 2 TB, OK)
physicaldrive 51:1:3 (port 51:box 1:bay 3, SAS, 2 TB, OK)
physicaldrive 51:1:4 (port 51:box 1:bay 4, SAS, 2 TB, OK)
physicaldrive 51:1:5 (port 51:box 1:bay 5, SAS, 2 TB, OK)
physicaldrive 51:1:6 (port 51:box 1:bay 6, SAS, 2 TB, OK)
physicaldrive 51:1:7 (port 51:box 1:bay 7, SAS, 2 TB, OK)
physicaldrive 51:1:8 (port 51:box 1:bay 8, SAS, 2 TB, OK)
physicaldrive 53:1:1 (port 53:box 1:bay 1, SAS, 2 TB, OK)
physicaldrive 53:1:2 (port 53:box 1:bay 2, SAS, 2 TB, OK)
physicaldrive 53:1:3 (port 53:box 1:bay 3, SAS, 2 TB, OK)
physicaldrive 53:1:4 (port 53:box 1:bay 4, SAS, 2 TB, OK)
physicaldrive 53:1:5 (port 53:box 1:bay 5, SAS, 2 TB, OK)
physicaldrive 53:1:6 (port 53:box 1:bay 6, SAS, 2 TB, OK)
physicaldrive 53:1:7 (port 53:box 1:bay 7, SAS, 2 TB, OK)
physicaldrive 53:1:8 (port 53:box 1:bay 8, SAS, 2 TB, OK)

Something like this?:

controller slot=2 create type=ld drives=51:1:1,53:1:1,51:1:2,53:1:2... raid=1+0 stripesize=default

Or would it go like this?:

controller slot=2 create type=ld drives=51:1:1,51:1:2,... raid=1+0 stripesize=default

My first syntax is the trick that is needed. Namely "drives=disk_from_left_drawer,disk_from_right_drawer,disk_from_left_drawer2,disk_from_right_drawer2,...".

Actually, now I am finding that hpacucli pays no attention to the order of drives in the listing. How can I pick which drives are mirrored to which drives? Any ideas?

Based on the link from above. I went ahead and rebooted and the default will now mirror across drawers. Still it would be nice if I could say exactly what I want to happen with the tool vs. having to depend on HP algorithm.
