For rac, you are going to need several separate shared disks between the two servers.

You need at least 1 OCR and 1 Voting disk.... no bigger than 100M each. Best practice is to have 2 OCR and 3 Voting, but this is a test environment so that is a bit of overkill. Then you will at least need 1 shared disk for data. My suggestion is to use ASM over ocfs. ASM is far better and most big RAC environments that I have worked on use it.

As much as I love Gentoo, RedHat seems to work best with Oracle. You might want to look at CentOs as the OS to run.

There are pretty comprehensive guides to running Oracle on RedHat here

ORACLE-BASE - Linux and Oracle

That might help you get started.

CTRLALTDEL(8)						     Linux Programmer's Manual						     CTRLALTDEL(8)

NAME

       ctrlaltdel - set the function of the Ctrl-Alt-Del combination

SYNOPSIS

       ctrlaltdel hard|soft

DESCRIPTION

       Based  on examination of the linux/kernel/sys.c code, it is clear that there are two supported functions that the Ctrl-Alt-Del sequence can
       perform: a hard reset, which immediately reboots the computer without calling sync(2) and without any other preparation; and a soft  reset,
       which sends the SIGINT (interrupt) signal to the init process (this is always the process with PID 1).  If this option is used, the init(8)
       program must support this feature.  Since there are now several init(8) programs in the Linux community, please consult	the  documentation
       for the version that you are currently using.

       ctrlaltdel is usually used in the /etc/rc.local file.

FILES
