CHAPTER 1
Introducing and Using SMU
This chapter introduces HP StorageWorks MSA2000 Family Storage Management
Utility (SMU), the web-browser interface for MSA2000 Family storage systems. It
also describes how to configure this interface by setting system preferences,
configuring users, and managing licenses.
This chapter contains the following sections:
■“What is SMU?” on page 17
■“Preparing to Use SMU” on page 18
■“Logging In and Out of SMU” on page 19
■“Understanding the Interface” on page 21
What is SMU?
Each controller module contains a SMU web server. SMU is the primary interface
for monitoring and managing MSA2000 Family storage systems from a
management host (a workstation with direct or network connections to a storage
system’s management ports).
SMU enables you to configure and maintain the storage for data hosts (a host that
reads/writes data to the storage system). You can manage the following physical and
logical storage components:
■Controller enclosures and controller modules
■Drive enclosures and expansion modules
■Power-and-cooling modules
■Drive modules
■Virtual disks (vdisks)
■Volumes
■Volume-to-host mappings, including logical unit number (LUN) assignments
■Master volumes, snap pools, and snapshots

18 HP StorageWorks 2000 Family Modular Smart Array reference guide • August 2008
SMU also includes monitoring and diagnostic features that enhance the reliability,
availability, and serviceability (RAS) of your storage system. You can configure the
transmission of event notifications (alerts), which can be sent to the screen or to
email addresses, and Simple Network Management Protocol (SNMP) traps, which
can be sent to an SNMP application. Events are also recorded in an event log on the
storage system from which they can be viewed.
In a dual-controller system, you can access all SMU functions from either
controller. If one controller becomes unavailable, you can continue to monitor and
manage the storage system from the partner controller.
Note – You can also monitor and manage storage using the scriptable command-
line interface (CLI), as described in the CLI reference guide.
Preparing to Use SMU
SMU supports the following browsers:
■Microsoft Internet Explorer 5.5 or later
■Mozilla Firefox 1.0.7 or later
Configure your browser as follows:
■SMU uses pop-up windows to display various statistics and progress messages.
You must enable pop-up windows on your browser for proper operation.
■Internet Explorer only:
■When SMU’s web page caching mode is enabled, which is the default, you can
optimize performance by setting the browser never to check for newer
versions of stored pages.
Note – This setting is used for all sites you visit with the browser.
■Clear the option Tools > Internet Options > Accessibility > Ignore Colors
Specified On Webpages.
■To optimize the display, use a color monitor and set its color quality to the
highest setting.
■To view animated status icons, set your browser to play animations.
■To navigate beyond the Log In page (with a proper login):
■Set your browser’s local-intranet security option to medium or medium-low.
■Verify that your browser is set to allow cookies for all sites, or at least for the
IP addresses of the storage system Ethernet management ports.

Chapter 1 Introducing and Using SMU 19
Logging In and Out of SMU
SMU distinguishes users by the IP addresses from which they log in. If you log in
to SMU using multiple browser instances on the same management host, SMU
considers all instances as a single user. Actions you take in one SMU instance are
reflected in the other SMU instances on the same host. A controller permits only
one browser instance for each management host IP address. Do not log in more than
once from the same host.
Each SMU user has a Monitor or Manage access level, as described in “User Roles”
on page 31. If a Manage user does not log out of SMU when finished using it, other
Manage users cannot log in to the same controller, and the IP address stays logged
in until the auto-logout timeout expires.
SMU permits one Manage user and up to five Monitor users to be logged into a
controller at the same time.
To log in to SMU:
1. In a web browser’s address field, type the IP address of one of the Ethernet
management ports and press Enter.
The Log In page is displayed.
Note – If the page does not display, verify that you entered the correct IP address.
In a dual configuration, if you still cannot access a controller, try entering the IP
address of the partner controller’s Ethernet port. If you still cannot access SMU,
verify the IP settings by using the CLI show network-parameters command
through a serial connection on a local management host.
2. On the Log In page, type the username and password.
The default Manage username is manage and the default password is !manage.
Note – To secure the storage system, change each Manage user’s password as
described in “Configuring User Access” on page 31.

3. Click Log In.
The Status Summary page displays the overall status and health of the system.
Note – If you cannot navigate past the Log In page, check the browser settings
described on page 18.
To log out of SMU:
1. Click Log Off at the bottom of the menu.
The Log Off page is displayed.
2. Click Log Off.
