Re: Hp smart array disabled
Hi
it is important to know what controller you are using, you cannot use the drive unless you configure raid on the raid controller. if the controller has hba mode option, only then the drives can be directly access in OS without raid configuration.
i would also like to know how did get to install the OS without the driver.

Re: Hp smart array disabled
Hello Sudhakar, first of all thanks for the reply. As I mentioned in my question, I have configured raid on the raid controller enabling a logical volume on the raid array (I hope this is the raid configuration that you are talking about).
But the OS installation is done by booting from the CD and proceed to install without having the hardware raid driver.
While the OS installation is not recognizing the Raid controller (Smart Array controller), it shows me both the two hard disks (sda and sdb) instead of one hard disk (sda). Because Smart Array controller driver is not loaded at the begining of the OS installation. I think I have explained well.
Thanks.

Re: Hp smart array disabled
might be good to include a screenshot. As Sudhakar mentioned please provide details on what disk controller(s) are in your system. The ML 310 Gen8 ships with the HP Dynamic Smart Array B120i Controller, but can also have a HP Smart Array P222 or P420 . Since you mention the OS reports two drives after creating the array, an easy guess would be that you are using the B120i embedded SATA controller. The B120i is a software based RAID controller and requires a special driver that controls the raid function. This driver is available for various versions of Windows and Linux. The Linux drivers are kernel release specific. The driver for the 'P' series controllers are included with all supported OS's.

Re: Hp smart array disabled
Hi,
Ok, I understand that the raid configured on the smart array controller.
Some OS will default storage controllers. and agree that it maight have worked.
while raid controller is not recognized the driver will not recognize, and once RAID is created the individual drives will not be available for access.
Please share the Controller Model. (hope this is not dynamic controller)

Re: Hp smart array disabled
Hello friends, as well as both of you said, the controller is HP Dynamic Smart Array B120i Controller. When I was installing Centos 7, I've faced no problem, installed as normal.
