HP XP7 Storage - Manual (Page 64)

If many-to-many connections are established between host adapters and storage system ports, you
can set one threshold value for the entire storage system. In this environment, you cannot set
individual threshold values for each prioritized WWN.
Prerequisites
•
Required role: Storage Administrator (System Resource Management)
•
You must enable the Remote Web Console secondary window. For details, see the HP XP7
Remote Web Console User Guide.
1. Display the Remote Web Console main window.
2. Click Reports > Performance Monitor > Performance Control to open the Performance Control
window.
3. Click to change to Modify mode.
4. In the Performance Control window, click Performance Control. The Performance Control main
window appears.
5. Select the WWN tab.
6. Select the All Thresholds check box.
7. Select IOPS or MB/s from the All Thresholds list, and do one of the following:
•
To specify the threshold value by using the I/O rate, select IOPS from the list below the
check box.
•
To specify the threshold value by using the transfer rate, select MB/s from the list below
the check box.
Even if the types of rates differ between the upper limit values and the threshold value,
the threshold control is effective for all non-prioritized WWNs.
8. Enter the threshold in the text box of All Thresholds.
CAUTION: If you enter zero (0) in a cell to disable the upper limit, the cell displays a hyphen
(-) and the threshold for the prioritized port becomes ineffective. If the thresholds of all
prioritized ports are ineffective, threshold control will not be performed but upper limit control
will be performed.
9. Click Apply to apply the settings to the storage system.

Managing host adapters
You can use Performance Control to change the name assigned to a host adapter and replace an
existing host adapter.

Changing the PFC name of a host adapter
Use Performance Control to assign a PFC name to a host adapter. Although you can identify host
adapters by WWNs, you might be able to identify host adapters more easily if you assign PFC
names. WWNs are 16-digit hexadecimal numbers that cannot be changed, whereas PFC names
need not be 16-digit hexadecimal numbers and can be changed as needed.
