Changing the SPM Name of a Host Bus Adapter The Server Priority Manager window allows you to assign an SPM name to a
host bus adapter (HBA). Although you can identify HBAs by WWNs (Worldwide
Names), you will be able to identify HBAs more easily if you assign SPM
names. WWNs are 16-digit hexadecimal numbers and cannot be changed.
However, SPM names should not necessarily be 16-digit hexadecimal numbers
and can be changed.
The following is the procedure for changing an already assigned SPM name.
For details on how to assign an SPM name, see Monitoring All Traffic between
HBAs and Ports.
To change an SPM name:
1. Start Server Priority Manager.
The Server Priority Manager window is displayed.
2. Ensure that the WWN tab is displayed.
3. In the upper-left tree, select a host bus adapter ( ) from below Monitor
and then right-click the selection.
4. From the pop-up menu, select Change WWN and SPM Name.
The Change WWN and SPM Name window is displayed.
5. Enter a new SPM name in the SPM Name box and then select OK. You can
use up to 16 characters for an SPM name.
6. In the Server Priority Manager window, click Apply.
The settings in the window are applied to the storage system.
