In your situation, where you're blocking user access to the login node, it 
probably doesn't matter. We use DOWN in most events, as INACTIVE would prevent 
new jobs from being queued against the partition at all. DOWN allows the jobs 
to be queued, and just doesn't permit them to run. (In either case, HOLDing 
PENDING jobs is redundant.)

Subject: [slurm-users] Quick hold on all partitions, all jobs

The IT team sent an email saying "complete network wide network outage tomorrow 
night from 10pm across the whole institute".

Our plan is to put all queued jobs on hold, suspend all running jobs, and 
turning off the login node.

I've just discovered that the partitions have a state, and it can be set to UP, 
DOWN, DRAIN or INACTIVE.

In this situation - most likely a 4 hour outage with nothing else affected - 
would you mark your partitions DOWN or INACTIVE?

Ostensibly all users should be off the systems (because no network), but 
there's always one that sets an at or cron job or finds that corner case.

Cheers
