Four C6420 chassis and sleds are being racked today.  We will configure them as SL7 WN as we get them up and ready to go.

All WN at MSU are now running SL7 as are 1/3 of the WN at UM.  We are developing a plan to move the balance of the UM WN to SL7 by the end of March.

As of today, all of our dCache servers are dual IPv4/IPv6 stacked.  We have not yet registered AAAA records though.

We have a network interruption between UM and MSU on Thursday night that will adversely impact HTCondor communications between our sites for a period of up to 4 hours.  Consequently we will be idling down all MSU WN starting later this afternoon so as to lose the minimal number of jobs during the outage.

On Friday after the MSU WN set is back online, we will add SL7 Analysis and LMEM queues, rounding out the SL7 Panda Queue complement for AGLT2.  When the complement of SL6 WN drops below some threshold, we will delete the SL6 Panda Queues and become SL7-only.

We are coordinating with the OSG folks on moving our non-ATLAS gate-keeper to SL7.  This will most likely happen some time next week.

Singularity is installed on all WN as they are built, but no special configuration considerations have been implemented.  Versions:

singularity-2.4.2-1.osg34.el7.x86_64
singularity-runtime-2.4.2-1.osg34.el7.x86_64
