WWN Tab of the Performance Monitor Window

When you click Go, Auto LUN / Perf Ctl / Perf Mon and then Auto LUN on the menu bar of the Remote

Web Console main window, Performance Monitor starts and the Auto LUN window is active. The

Auto LUN window includes the WWN tab, which lets you view statistics (I/O rates, transfer rates, and

average response time) about traffic between host bus adapters in the hosts and ports on the storage

system.

CAUTION:

The WWN tab is grayed out and cannot be used if XP Performance Control is not enabled.

A WWN (World Wide Name) is a 16-digit hexadecimal number used as the unique identifier for a

host bus adapter. Host bus adapters are contained in hosts and serve as ports for connecting the

hosts and the storage system. One WWN represents one host bus adapter.

For details on how to use this window, see “Monitoring Paths between Host Bus Adapters and

Ports” on page 92.
