If all goes well, we will not need the full length of this downtime. The intervention will need to also upgrade the kernel, see KernelUpdate. ---++ Documentation Details for how all the upgrade will have to be performed can be found here on http://lcg.web.cern.ch/LCG/Sites/releases.html The following documents are relevant: * [[http://grid-deployment.web.cern.ch/grid-deployment/releaseNoteLCG-2.7.0.txt][Release Notes]] (plain text file) * LCG2 Manual *Upgrade* Instructions ([[http://grid-deployment.web.cern.ch/grid-deployment/documentation/LCG2-Manual-Upgrade.pdf][pdf]], [[http://grid-deployment.web.cern.ch/grid-deployment/documentation/LCG2-Manual-Upgrade][html]]) * LCG2 Manual *Installation* Instructions ([[http://grid-deployment.web.cern.ch/grid-deployment/documentation/LCG2-Manual-Install.pdf][pdf]], [[http://grid-deployment.web.cern.ch/grid-deployment/documentation/LCG2-Manual-Install][html]]) * LCG2 *Testing* of a site ([[http://grid-deployment.web.cern.ch/grid-deployment/documentation/LCG2-Site-Testing.pdf][pdf]], [[http://grid-deployment.web.cern.ch/grid-deployment/documentation/LCG2-Site-Testing/][html]]) * LCG2 User Guide ([[https://edms.cern.ch/file/454439//LCG-2-UserGuide.pdf][pdf]], [[https://edms.cern.ch/file/454439//LCG-2-UserGuide.html][html]]) gives detailed information on how to use the middleware and has some insights also into site configuration * [[https://uimon.cern.ch/twiki/bin/view/LCG/ClassicSeToDpm][Upgrading a Classical SE to a DPM]] - this is exactly what we need to do with our SE Other interesting documentation * [[http://grid-deployment.web.cern.ch/grid-deployment/documentation/Maui-Cookbook.pdf][Maui Cookbook]] * First-time site configuration description ([[http://grid-deployment.web.cern.ch/grid-deployment/documentation/LCG2-Site-Setup.pdf][pdf]],[[http://grid-deployment.web.cern.ch/grid-deployment/documentation/LCG2-Site-Setup][html]]) ---++ Upgrade Plan The upgrade has to start with the KernelUpdate on all nodes.
