VMware has released new Driver rollup ISO image for VMware ESXi 5.5.0 few weeks back. There weren’t much news about this release so I thought is’s a good idea to point out to which usages this ISO is destined. This is an installable iso ISO which is suppose to be used for clean installations only so upgrades aren’t supported.
The ISO includes original IOVP certified drivers (IOVP - I/O Vendor Partner Program) provided by device manufacturers which were not present on the ISO initially (or are updated) released when vSphere 5.5 came out.
The ISO shall detect recent hardware or recent I/O devices more easy compared to drivers included with the ESXi inbox drivers.
By reading the release notes:
Important: The ESXi 5.5.0 Driver Rollup 1 is designed for fresh installations of ESXi hosts. VMware does not support using the ESXi 5.5.0 Driver Rollup 1 to upgrade an existing ESXi installation.
You should make sure that If you install ESXi by using this ISO then when patching by using the CLI make sure that you use #esxcli software vib update and not the #esxcli software vib install command. Otherwise you might experience PSOD.
Even if you use this ISO to try to upgrade existing ESXi host, and the installer detects that there is an existing installation of ESXi, you shall NOT select the upgrade option as it’s unsupported and the ESXi 5.5.0 Driver Rollup 1 installation will overwrite the existing installation.
The VMware IOVP program is part of VMware Developer center website, and has some cool stuff there hidden. By navigating through some of the free content there I stumbled through a vCloud SDK poster. It’s “hidden” at the communities page here – get your copy in PDF format.
