386 XgOS User’s Guide • September 2014
You must upgrade one ESX Server and one at a time. After they reboot running the
new software version, you will use VMotion to move all guest machines to the
upgraded server and upgrade the second ESX Server and Fabric Interconnect. In the
procedures that follow, ESX Server 1 and Fabric Interconnect 1 are upgraded first.
You can select whichever server and Fabric Interconnect makes sense for your
system.
The upgrade procedures show an upgrade from XgOS version 3.5.0 to XgOS version
3.6.0 and to version 3.5.0 host drivers. The steps to upgrade are applicable to nearly
all upgrades between versions of XgOS and host driver, and to all XgOS software of
version 3.6.0 or later. However, there might be syntax differences between different
versions of host operating systems. In the example used for this procedure, the
example package names and versions may be different than what is in use in your
environment.
You do not need to keep the latest version of host drivers synchronized with the
latest version of XgOS, but it’s best to keep the host drivers and XgOS versions close
in terms of upgrades. For example, you would not want to use version 2.8.0 host
drivers and version 3.6.0 XgOS due to the availability of new features,
enhancements, and other optimizations that are present in newer host drivers.
Note – You can download the latest supported host drivers from Oracle’s Xsigo
Customer Support site. Refer to the Release Notes for download instructions.
