- ESXi Config backup can only be restore on the same ESXi version (so its not sooooooooo usefull in your case)
- vCenter with VUM works only if vCenter runs not on that host which you wanna be to upgraded. But vCenter is great so see of Updates are needed and if youre compliance and it works with vHW und VMware Tools mass upgrades
- ESXi use 2 boot banks and it offer a role back if something goes wrong
Use putty log file to cover the following
- Shutdown all VMs and set the host into MM
- Upgrade the Firmware by using Dells latest platform ISO and use iDRAC Console/Virtual Media. You can enable a one time boot form VirtualCDROM
- Upgrade ESXi by using the Dell Custom ISO trough iDRAC Console/Virtual Media. You have to select upgrade and SD card!
- Apply latest updates trough ESX shell
What can go wrong?
- There maybe is a legacy driver from 5.0.0 or so installed. You have to remove them manually
- The famous error 28 - no space left on devise
Thanks, Joerg. I will certainly pay attention to your answers with my next steps.
Yes you can take a backup of the SDcard and run the following single command to take the complete network , storage and other configuration back up of the esxi prior to the upgrade.
To synchronize the configuration changed with persistent storage, run this command:
To backup the configuration data for an ESXi host, run this command:
Note: The command should output a URL in which a web browser may be used to download the file. For example :
Bundle can be downloaded at : http://*/downloads/123456/configBundle-xx.xx.xx.xx.tgz
Where * denotes the host IP/FQDN.
The esxi upgrade can be done from the vcenter, command line or the iDRAC depending upon your convenience.
Vcneter: download the iso and create a baseline and follow the below link:
Download the esxi 6.7 offline zip bundle , add it to the datastore and execute the following commands:
esxcli software sources profile list -d vmfs/volumes/datastore1/data/ESXi670-xxxxxxxxx.zip
Note: The -p stands for “profile” and the -d stands for “depot”.
esxcli software profile update -d /vmfs/volumes/datastore1/data/ESXi670-xxxxxxxx.zip -p ESXi-6.7.0-xxxxxxxxxxx-standard Update Result
Mount the iso and boot the esxi form the iso to initiate the upgrade
