Description:
Microsoft patches and hotfixes will be deployed as follows on:
~200 Hypervisors in the CVI service, hosting Virtual Machines in the Self-Service as well as in hostgroups dedicated to BE/CO, Engineering Services, IT/GT, EN/ICE, IT/UDS, IT/OIS and IT/CS.
The upgrades will take place between 07:00 and 08:30, and involve a reboot of the hypervisors. The Virtual Machines hosted on those servers will be automatically suspended into a 'Saved State', and will resume once the hypervisor has restarted (typically within 5 minutes). From the VM perspective this intervention is therefore largely transparent.
All Virtual Machines are expected to be back by 08:30.
Up-to-date information about which of the hypervisors host which Virtual Machine can be obtained from the VMM website (go to https://vmm.cern.ch -> "Manage my Machines" -> Click on VM name for details -> Look for "VM Host") or from the LANdb Network Database (http://network.cern.ch).
The upgrade schedule is:
BE-CO : cernvs64 cernvs65 cernvs66 cernvs67
Eng Serv : caevmsrv26 caevmsrv27 caevmsrv28 caevmsrv29 caevmsrv30
caevmsrv31 caevmsrv33 caevmsrv34 caevmsrv35 caevmsrv36
caevmsrv37 caevmsrv38 caevmsrv39 caevmsrv40 caevmsrv41
caevmsrv42 caevmsrv43 caevmsrv44 caevmsrv45 caevmsrv46
caevmsrv47 caevmsrv53 caevmsrv54 caevmsrv55 caevmsrv56
caevmsrv57
After an update on the previous days (18-20/06). Additional reboot is necessary on the following Hypervisors:
Self-Service : cernvs27 cernvs32
EN-ICE : cernvs82
IT-GT : lxvmpool08
The reboot is planned at 7:30 AM.
