HP OneView for VMware vCenter - Manual (Page 103)

Cannot configure HP MSA P2000 G3 array when using user-created account
When configuring HP MSA P2000 G3 arrays, an Unable to Authenticate error occurs.
Cause: The WBI does not include an option to enable SMI-S when a new user is created. It has
an option to enable FTP, CLI, and WBI only. This is a WBI limitation.
Action: Use the CLI with the manage option to create the user.
For example:create user newUser level manage interfaces cli, ftp, smis,
wbi password password
