Changing the Performance Control Name of an HBA
The Performance Control window allows you to assign a Performance Control name to a HBA. Although
you can identify HBAs by WWNs, you will be able to identify HBAs more easily if you assign
Performance Control names. WWNs are 16-digit hexadecimal numbers and cannot be changed.
However, Performance Control names do not need to be 16-digit hexadecimal numbers and can be
changed.
The following is the procedure for changing an already assigned Performance Control name. For
details on how to assign a Performance Control name, see
“Monitoring All Traffic between HBAs and Ports” on page 39.
To change a Performance Control name:
1. Start XP Performance Control (see “Starting Performance Control” on page 34).
The Performance Control window is displayed.
2. Ensure that the WWN tab is displayed (Figure 4 on page 21).
3.
In the upper-left tree, select a HBA (
) from below Monitor and then right-click the selection.
4. From the pop-up menu, select Change WWN and Performance Control Name.
The Change WWN and Performance Control Name window is displayed (Figure 14 on page 45).
5. Enter a new Performance Control name in the Performance Control Name box and then click
OK.
NOTE:
You can use up to 16 characters for a Performance Control name.
6. In the Performance Control window, Click Apply .
The settings in the window are applied to the storage system.
