1. How to Fix ssh <USERID>@aac1.amd.com failed with Host key verification failed message

The Slurm login node was changed during maintenance, so the host key fingerprint is different. SSH users may see a failure to login with a WARNING message such as one shown below. Please update $HOME/.ssh/known_hosts by removing the existing entries for dell-r08-01 and retry ssh <USERID>@aac1.amd.com and accept the new fingerprints:

ECDSA key fingerprint is SHA256:u1u0/uh0GLcs19KNHrmZIA6EDLMvJACK5y2fMkVg1fg.
ECDSA key fingerprint is MD5:76:6a:a4:34:56:c0:04:fa:7f:84:e6:85:0b:f1:65:e5.

Solution:

1. First remove existing fingerprint of old Slurm login host: ssh-keygen -R aac1.amd.com
2. Login to the AAC Plano Slurm cluster: ssh <USERID>@aac1.amd.com
3. Enter "yes" to accept new host key fingerprint at the prompt to continue to login.

2. How to Fix The selected queue is no longer available error

Solution:

The Slurm partition/queue names were changed during the maintenance to remove duplicate queue names and standardize on one set. The new partitition names can be used to allocate single node or a multi-node cluster using the Slurm commands.
