VCP 5 – Study Blueprint Section 1.3 Plan and Perform Upgrades of vCenter Server and VMware ESXi
Identify upgrade requirments for ESXi Hosts
- KB Article 2005102 – http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2005102
- Hardware is compliant
- Processor is 64bit
- Intel VT is enabled
- Minimum 2GB if RAM
- at least 1 ethernet adapter
- supported storage system
- Must not have any VMs greyed out (orphaned or inaccessable)
- Must be at version 4.0 or higher to upgrade to ESXi 5.0
- If upgrading from ESXi 3 or earlier it is require to upgrade to ESXi 4 first.
Identify Steps required to upgrade a vSphere implementation
- in-place upgrade of vCenter Server
- in-place upgrade of Update Manager
- download the upgrade bundle for the upgrade path
- import the upgradebundle into update manager
- reconfigure licensing
- upgrade VMs
Upgrade a vNetwork Distributesd switch
- 3 versions available (4.0, 4.1 and 5.0)
- To Upgrade:
- Using vSphere Client go to home and then networking
- Select the distributed switch and then the summary tab
- Select to upgrade
- ensure all hosts report as compatible
- finish the upgrade
- upgrading adds functionality and alters the compatiblity.
Upgrade from VMFS3 to VMFS5
- Upgrading can be done live
- Upgraded datastore will only be accesable by othe ESXi 5 hosts not older hosts
- Upgrade Process:
- using vSphere Client select home and then the datastores and datastore clusters icon.
- select the datastore to be upgraded and then the configuration tab
- on the right select upgrade to VMFS5
- Click OK to start the upgrade
Upgrade VMware Tools
- using vSphere Client select the VM and then right click and select guest/install/upgrade vmtools
- Process will prompt for automatic or interactive upgrade process.
- If automatic is selected the vm will automatically upgrade and restart the VM.
- If Interactive is selected the VM will require th upgradelogs to be answered and the VM restarted by the user.
Upgrade Virtual Machine Hardware
- using vSphere Client right click on the VM and select upgrade the Virtual Machine Hardware
- This process should be done when VM is powered Off
- Have seen instances where the VM will not function after the upgrade so backing up the VM may be wise
Upgrade an ESXi Host using vCenter Update Manager
- Ensure that vCenter Server and Update Manager are already upgraded to the target release
- Download the upgrade path bundle for the upgrade required
- import the bundle into update manager
- Create a new upgrade baseline and associate the upgrade bundle with the baseline
- Attach the baseline to the ESXi host that needs to be upgraded
- Select the ESXi Host and then the update manager tab and scan the Host for compliance (select the upgrade option)
- ensure the Host is in maintenance mode.
- remediate the host.
Determine whether an in-place upgrade is appropriate in a given upgrade scenario
- Some upgrade scenarios are not supported and an upgrade is not possible they are:
- ESX 3.x needs to be upgraded to ESX4 or ESXi4 first.
- ESX 3 host that was upgraded to 4 and the partition layout is incompatible with ESXi 5
- Installation location needs to be changed
- If auto deply needs to be used
