vSphere 5.5 & the Isilon NAS VAAI Plugin – Part 1
Just a quick heads up for anyone running vSphere 5.0/5.1 with the Isilon NAS-VAAI plugin for vSphere/OneFS 7.0.
If you are planning to upgrade to vSphere 5.5, there are a couple things to know. The plugin does not work in 5.5 (new or upgraded) installations.
I built a new vSphere 5.5 installation, and the plugin loaded fine. But… When attempting to configure the credentials for the OneFS 7.0 cluster you are connecting to, the authorization tool fails to operate properly.
In a new vSphere 5.1 installation, the error is not present.
I upgraded a vSphere 5.1 host to 5.5 to determine if I would retain functionality. Maybe the authorization piece (auth_gen) was the only part affected. On this host that had successfully used the plugin, it no longer worked after the upgrade to 5.5.
In vSphere 5.5, the libssl.so shared library is libssl.so.1.0.1, while in vSphere 5.1, it is libssl.so.0.9.8.
I reached out to the team responsible for the plugin, and have confirmed they are aware of the issue, and working on a resolution.
