WWNs are 16-digit hexadecimal numbers used to identify HBAs. For details on how to find WWNs, see HP StorageWorks XP24000/XP20000 Auto LUN Manager User's Guide. Ensure that all HBAs connected to ports in the storage system are monitored. Use the WWN tab of the Performance Control window to define which port is connected to which HBA. Place icons for HBAs connected to each port below the Monitor icons. In network B, each of the four ports is connected to three HBAs (wwn01, wwn02, and wwn03). Place the HBA icons of wwn01, wwn02, and wwn03 below the Monitor icons for all the four port icons (shown in Figure 9 on page 33). The resulting definitions on the window are as follows: 2. 32 XP Performance Control Operations Figure 9 Specifying HBAs to be Monitored For more detailed instruction, see "Setting Priority for Ports on the Storage System" on page 38. NOTE: XP Performance Control is unable to monitor and control the performance of hosts whose HBAs icons are placed below the Non-Monitor icon. Set priority to HBAs using the WWN tab of the Performance Control window. In network B, the production server is given high priority and the development server is given low-priority. If your network is configured as in Figure 8 on page 32, you must give high priority to wwn01 and give low-priority to wwn02 and wwn03. To give priority to the three HBAs, take the following steps (see Figure 10 on page 33 below): a. In the WWN tab, select one of the four ports that the HBAs are connected to (that is, ports 1A, 1C, 2A, and 2C). Also, set wwn02 and wwn03 to Non-Prio. . Figure 10 Priority specified in the Performance Control Window 4. Monitor traffic between host bus adapter and ports. You must obtain statistics about traffic between HBA and ports. If your network is configured as network B, you must do the following: · Measure traffic between port 1A and the three HBAs (wwn01, wwn02 and wwn03). · Measure traffic between port 1C and the three HBAs. XP24000/XP20000 Performance Control User's Guide 33 · Measure traffic between port 2A and the three HBAs. · Measure traffic between port 2C and the three HBAs. Figure 11 on page 34 illustrates the I/O rate using the paths between each port and the HBAs.
