Notes:
If the selected host bus adapter is connected to multiple ports, when you
select the host bus adapter and select the Delete WWN pop-up menu, a
message will appear that asks you whether to move the host bus adapter
from Monitor to Non-Monitor below all other ports, too.
If the selected host bus adapter is contained in an SPM group, a message
will appear that tell you to delete the host bus adapter from the SPM group
on ahead. You cannot move a host bus adapter which is contained in an
SPM group from Monitor to Non-Monitor. For details on how to delete a
host bus adapter from an SPM group, see Deleting an HBA from an SPM
Group.
6. Click OK for the confirmation message that asks you whether to delete the
host bus adapter.
The deleted host bus adapter (WWN) is moved from Monitor to
Non-Monitor.
7. Click Apply in the Server Priority Manager window.
The settings on the window are applied to the storage system.
Analyzing Traffic Statistics
The traffic statistics reveal the number of I/Os that have been made via ports
from HBAs. They also reveal the amount of data that have been transferred
between ports and HBAs. You must analyze the traffic statistics to determine
upper limit values that should be applied to I/O rates or transfer rates for low-
priority HBAs.
The following is the procedure for using the Server Priority Manager window
to analyze traffic statistics. You can also use the Performance Management
window to analyze traffic statistics. Performance Monitor can display a line
graph that indicates changes in traffic (For details, see Viewing I/O Rates for
Disks and Viewing Transfer Rates for Disks).
To analyze traffic statistics:
1. Start Server Priority Manager.
The Server Priority Manager window is displayed.
2. Select the WWN tab.
3. Select All from the list at the top right corner of the window.
4. Do one of the following:
– To analyze I/O rates, select IOPS from the list at the upper left corner.
– To analyze transfer rates, select MB/s from the list at the upper left
corner of the list.
