Updating my answers:
1. Yes, AirWave has been successfully installed on RHEL 6.2
2. The rpm file was redundant as everything can be done using the installation ISO and upgrade tar file
The base portion of the OS should be installed following this KB article:
http://kb.airwave.com/?sid=50140000000bEMt
And then when it comes to the AMP rpm portion -> do the following:

(https://arubanetworkskb.secure.force.com/pkb/articles/FAQ/AMP-7-6-on-RHEL-Cent-6-2)
1. Install using the .tar file
Installing the AMP.rpm simply puts svn into /root and creates the /root/amp-install symlink. The same thing can be accomplished by unpacking the tar file and manually creating the link (if desired).
# tar xzf /root/AMP-7.6.1-x86_64-cvs.tar.gz
# ln -s ./svn/mercury/install/amp-install amp-install
The tar file has all of the requisite security update packages (for upgrades), so the install will work like a champ.
2. Add kernel-headers to the "rpms to install" list .
################################################
From there, follow the installation guide (found on the support site in documentation->AirWave->7.6)
3. I've got confirmation that the security updates do not happen for RHEL. Upgrade output will show a message that says something to the effect "RPM management / upgrades are the responsibility of the customer when running RHEL".
4. Aruba support will still provide support. The RPMs were removed since the installation can be achieved using the ISO and upgrade tarball.
And then my previous sidenotes still apply:
RHEL has been recognized in the past to not always default to the custom bashrc that's built into AirWave, so some aliases will have to be typed out in order to run the desired commands.
For VM server sizing, resources should be increased 20% more to account for VM overhead.
If you plan to run 3rd party utilities, be sure to notify support as they may be directly affecting AirWave performance.
