Patching and Pausing Jobs

On HPC1 use squeue to determine what jobs are running on what nodes: 
 squeue --long

 JOBID PARTITION NAME USER STATE TIME TIME_LIMI NODES NODELIST(REASON)
 8957 compute a1748355 azeezoe PENDING 0:00 1-00:00:00 1 (Dependency)
 8958 compute a1748355 azeezoe PENDING 0:00 20:00:00 1 (Dependency)
 8955 compute a1748355 azeezoe RUNNING 1:25:26 7-00:00:00 1 hpc2
 8956 compute a1748355 azeezoe RUNNING 1:26:41 7-00:00:00 1 hpc2
 
 Take note of what's running where, in this example let's say hpc2 is about to undergo schedule maintenance. Simply pause the jobs running on it: 
 scontrol suspend 8955,8956
 
 Once it's back online, resume the jobs: 
 scontrol resume 8955,8956
