HP P410 RAID CARD Issue – unassigned drives not detected by the OS

hpraid

i just bought lot of HP DL180 G6 Servers,

it's using HP P410 RAID Card,

i plugged 12 x 2TB SAS Drives + 2 x 73GB SAS (for OS – RAID1)

all drives showing up IN RAID Creating array page,

so i just created RAID1 Array for 2x73Gb to install OS (Centos 6)

OS installed fine,

but i can't detect the rest of unassigned drives (that's not in RAID Arrays)

so my Q. is :

is there any way to make unassigned drives showing up in OS (without creating raid array for them) ?

i don't want to create RAID arrays for them, i just want them showing up like all Dell servers i have,

if i change RAID Card Mode to HBA, is that help ?

any advices ?

Thanks

The Smart Array P410 (and all Smart Array controllers) are RAID devices only. There's no HBA or pass-through mode.

What are you attempting to do? Are you installing something like ZFS or Windows Storage Spaces where you want to pass full disks to the operating system to be managed?

If so, creating a bunch of RAID 0 single-disk logical drives is the wrong choice!

If you do this, you will lose hot-swap ability during a drive failure. If a disk fails, that RAID 0 logical drive fails and won't be rescanned by your operating system without a reboot or Smart Array reconfiguration. A dedicated HBA is a better choice, depending on what you're doing...
