Kirk Kosinski created CLOUDSTACK-399:
----------------------------------------

             Summary: Document vSphere / ESXi patch installation procedure
                 Key: CLOUDSTACK-399
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-399
             Project: CloudStack
          Issue Type: Improvement
          Components: Doc
    Affects Versions: 4.0.0
            Reporter: Kirk Kosinski
            Priority: Minor


Currently the installation guide has a section for patching/upgrading XenServer hosts (Upgrading
XenServer Versions). It would be good to have a documented procedure for patching/upgrading
vSphere as well. The following procedure has been verified by QA.

1. Unmanage the cluster in CloudStack. This can be done from the CloudStack UI.
2. Do the following 3 steps for each of the ESXi hosts (2.a followed by 2.b, and 2.c) in the
cluster:
2.a. Move each of the ESXi hosts in the cluster to maintanance mode and ensure all the VMs
get migrated to other hosts in that cluster. If there is only 1 host in that cluster, shutdown
all VMs and move the host into maintenance mode.
2.b. Apply the patch on the ESXi host. Reboot the host if required.
2.c. Move the host out of maintenance mode.
3. Manage the cluster in CloudStack. This can be done from the CloudStack UI.
4. Verify the host state is properly synchronized and updated in the Cloudstack database (or
via UI... state should be "Up").
