RHEL 7 Image Retirement

On 4pm at July 26, we will drain the last of the RHEL 7 compute nodes that have not been converted to RHEL 9 yet. Jobs that already started running will continue to run. Pending RHEL 7 jobs that have not started by that time will be cancelled. The remaining RHEL 7 login nodes will also be converted to RHEL 9. ssh.rc.byu.edu will then be pointed to the RHEL 9 login nodes. rhel9ssh.rc.byu.edu will be aliased to point to ssh.rc.byu.edu.
