Alice Hi and welcome to linux.org
I note you are using Red Hat ... do you have a support agreement with them?
With both this and your other 2 Threads, I am not sure you are going to get your answers here?
We have a couple of Sysadmins amongst our ranks, but we are volunteers from all around the world, and I just don't know that you are going to get quick answers, if you need them.
Cheers
Chris Turner
