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 - HP StorageWorks 2012sa | HP StorageWorks 2000 Modular Smart Array Reference Guid - Page 18
that enhance the reliability, availability, and serviceability (RAS) of your storage system. You ), as described in the CLI reference guide. Preparing to Use SMU SMU supports the following browsers: ■ Microsoft Internet HP StorageWorks 2000 Family Modular Smart Array reference guide • August 2008 - HP StorageWorks 2012sa | HP StorageWorks 2000 Modular Smart Array Reference Guid - Page 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 - HP StorageWorks 2012sa | HP StorageWorks 2000 Modular Smart Array Reference Guid - Page 20

Configuring Host Ports This section describes how to configure host ports on Fibre Channel (FC) or iSCSI controller modules. No host-port configuration is needed for SAS controller modules. Configuring FC Host Ports On the Host Port Configuration page you can view the location, link speed, and - HP StorageWorks 2012sa | HP StorageWorks 2000 Modular Smart Array Reference Guid - Page 40
power down and power up or after a loop initialization process (LIP). This setting enables the FC loop initialization process to determine the loop ID. 40 HP StorageWorks 2000 Family Modular Smart Array reference guide • August 2008 - HP StorageWorks 2012sa | HP StorageWorks 2000 Modular Smart Array Reference Guid - Page 41
■ 0-125 - Select a specific number if you want the loop ID to stay the same after you power down and power up. SMU cannot determine which loop IDs are available. If the controller cannot get the specified loop ID during the loop initialization process, it tries to get a soft address. 4. Click Save - HP StorageWorks 2012sa | HP StorageWorks 2000 Modular Smart Array Reference Guid - Page 42
