Understanding Basic SL150 Concepts
1-2 StorageTek SL150 Modular Tape Library User's Guide
RBAC designs limit the use of controls and interfaces to users that have predefined job
roles. An administrator creates individual user accounts for each person that needs
access to the system. Each account has its own, uniquely identifiable log-in name and
personal password. The administrator then assigns each account to a distinct role.
The RBAC approach makes it easy to consistently manage access privileges: you
assign privileges to the job function and everyone who performs that function
automatically has what they need. But it also makes managing individual usage no
less easy: every user retains an individual log-in account that can be monitored and
audited.
The SL150 recognizes the following user roles:
■ Viewer Role
■ Operator Role
■ Service Role
■ Administrator Role.
Viewer Role
The Viewer role has view-only access to the library. Viewers can login, monitor library
operations, and view component states and properties. But they cannot otherwise alter
the configuration or operation of the library.
The Viewer role should be the norm for most users, and the local operator panel is
permanently assigned to it. Since libraries generally operate automatically, under the
control of a host-side backup, storage-management, or library-management
application, user intervention via the browser-based user interface is not normally
required. Checking for problems and gathering routine information are the only tasks
that are required under normal conditions.
Operator Role
The Operator role has limited control over the operation of the library, but no control
over its configuration.
Under normal circumstances, operators will spend most of their time monitoring the
library for problems using the Library Management Screen, Drives Management
Screen, and Tapes Management Screen. A storage- or backup-management software
application running on the library host controls most routine operations, including
movement and mounting of data cartridges and auditing. In most cases, drive
cleaning is managed automatically by the library's native Drive Auto Clean feature or
by the application software.
When necessary, however, operators can perform a range of tasks using the SL150
browser-based user interface. These include:
■ Taking the Library On and Off Line
■ Powering the Library On and Off
■ Importing and Exporting Media
■ Run a Library Self Test.
Service Role
The Service role has all of the capabilities of the Administrator role, except for user
administration. When you require the assistance of an Oracle service representative,
you create a log-in account for the service person and assign the account to the Service
