Install Oracle Linux 6.4 on HP ProLiant DL380e Gen8 server
Solution 1:
I blame HP for convincing people to buy the ProLiant DL360e/DL380e series of servers. The storage controller is a big compromise on those servers. Here, you basically installed onto one of the two disks.
The HP Dynamic Smart Array needs a binary driver to really function... See this Red Hat knowledge base article. You'll have to slipstream it into the installation.
In order to install onto your server model, you'll require a driver disk for use during the installation process. The driver you need is the hp-vsa
module. The install will need to be performed with a USB key.
Here's the link to the driver. Choose the right binary driver for your EL version (6.4)
Here are the installation instructions.
Solution 2:
The ilo can't display drive information if you don't have the raid tools suite installed on the machine, so that doesn't mean anything.
I'd boot to the controller interface, and make sure the array is configured correctly.
