> Summary: A 12-hour power outage at the RACF will affect a

> Group Responsible: Linux Farm group
>
> Affected Area: Linux Farm cluster

> The following systems will be unavailable during the
> outage. In addition, all ATLAS interactive nodes
> (acas0001-0012) will suffer two brief outages in connection
> with the power outage. No adverse effects on Condor jobs
> submitted from these machines are expected.

> ATLAS : acas0015-0064, acas0097-0127 (batch)
>        acas0410-0612, acas0625 (batch)
> BRAHMS: rcas0007-0011 (interactive)
> LSST:   lsst01-20 (interactive and batch)
> PHENIX: rcas2001-2060 (batch)
> STAR:   rcas6013-6019 (interactive)

> Regarding computing capacity, PHENIX and STAR will only lose a small  
> fraction (~12%), ATLAS will lose about ~27%, BRAHMS will lose about  
> ~50% and LSST will lose 100% during the outage. In preparation for  
> the outage, these nodes will be closed to new jobs about 24 hours  
> ahead of the outage, and jobs will be allowed to drain out.
