From: Kim, DongInn Subject: Network change of the CREST SVN/trac server (tiger) Date: April 8, 2014 10:01:46 AM EDT

Dear All,

The CREST SVN/trac server machine (tiger.crest.iu.edu) is requested to change its subnet and I am planning to switch its IP address for the change of the subnet.

I would like to setup the schedule to update the DNS information of the following hostnames in tiger.

- svn.crest.iu.edu - svn.mpi-forum.org - svn.open-mpi.org - svn.osl.iu.edu - svn.oscar.openclustergroup.org - svn.scalabletools.org - git.open-mpi.org

The IP transition date and time: April 10, 2014 6:00am-7:00am Pacific US time 7:00am-8:00am Mountain US time 8:00am-9:00am Central US time 9:00am-10:00am Eastern US time 1:00pm-2:00pm GMT

The list of services that may not be available: - Web/SVN services: https://svn.crest.iu.edu/svn/* https://svn.open-mpi.org/svn/ompi https://svn.mpi-forum.org/svn/mpi-forum-web/ https://svn.open-mpi.org/trac/ompi https://git.open-mpi.org/trac/hwloc ...

tiger.crest.iu.edu (129.79.13.91 --> 129.79.39.209) * svn.crest.iu.edu IU CS

tiger-virt1.crest.iu.edu (129.79.13.23 --> 129.79.39.200) * svn.mpi-forum.org University of Illionis

tiger-virt2.crest.iu.edu (129.79.13.24 --> 129.79.39.201) * svn.open-mpi.org IU CS

tiger-virt3.crest.iu.edu (129.79.13.7 --> 129.79.39.205) * svn.osl.iu.edu IU CS

tiger-virt4.crest.iu.edu (129.79.13.9 --> 129.79.39.207) * svn.oscar.openclustergroup.org IU CS

tiger-virt5.crest.iu.edu (129.79.13.13 --> 129.79.39.199) * svn.scalabletools.org IU CS (?)

tiger-virt6.crest.iu.edu (129.79.13.10 --> 129.79.39.198) * git.open-mpi.org IU CS

I have already prepared the IP transition on tiger to make the new IP addresses provide the same services on tiger so that I hope that there is no actual outage of the services other than the rebooting time.

If you happened to use the IP address on your cronjob or programs, please make sure that you switch it with the new one.

IMPORTANT ========================================= tiger will need to reboot to kick in a new kernel and mount the NFS space with the new IP addresses at the same time. ==========================================

Please let me know if you have any questions or concerns about this IP transition.

Regards,
