Hello asis,

Isilon documentation, especially regarding commands, is typically publish based on OneFS version. What version of OneFS are you working with? The version number will be listed in the upper right corner of the webui usually, or from the command line using:

#uname -a

Thanks for your response and guidance. The OneFS release is 7.2.1.1
