So you've made the choice than performance and usable space, above, are
more critical than manageability, below. BTW, if you are using all 8
drives in an mdraid array, what drive(s) are you booting the system
from? The DL380 G7 only has 8 drive slots. Are you booting from the md
array?

Unfortunately this is beyond my experience/expertise at this point.
Unless someone else here can help you, I suggest you contact HP support,
as the problem you're having is with their closed source commercial
SmartArray support tools. You may also want to inquire about this on
one of the mailing lists dealing with storage, such as linux-raid,
linux-scsi, etc, as someone there may have experience with such an HP
hardware setup.
Or you can swap the p410i for an LSI 9211-8i in HBA mode and eliminate
all of your current problems instantly. The only downside is you'll
lose a little write performance due to the lack of write cache.
Everything else is upside. I think I mentioned this option before.
It's ~$250 USD. What's your time worth Julien? How much time have you
spent on this already?
