User Authentication
HP Clustered File System can be managed via the HP Management
Console GUI or from the command line. The HP Clustered File System
mx command provides command-line equivalents of Management
Console operations. HP Clustered File System also provides other
commands to perform various cluster operations.
HP Clustered File System provides several ways to authorize users to
access the cluster and perform cluster operations:
• Windows single sign-on. HP Clustered File System uses the Windows
credentials to authorize access to the cluster.
• The HP Clustered File System .matrixrc file. This optional file is stored
on the local machine and contains connection information for the
servers in the cluster. It can also store the usernames and passwords
needed to access the servers.
• On the command line, the --username and --password options can be
used to provide credentials for an mx command.
• If HP Clustered File System cannot authenticate a user via the
methods above, it prompts for the username and password.
When the HP Management Console is used, credentials are processed in
this order:
•If a .matrixrc file exists, the user credentials specified in the file for the
selected server are used.
• If there is not a .matrixrc file or the file does not include user
credentials, the credentials provided by single sign-on semantics are
used.
• If single sign-on fails, the user is prompted for a user name and
password.
