Set priority to host bus adapters
•
Set an upper limit on traffic at non-prioritized WWNs
•
Set a threshold, if necessary
If many-to-many connections are established between host bus adapters and
ports, you should specify the priority of I/O operations on each host bus
adapter. You can specify the upper limit values on the non-prioritized WWNs.
If necessary, you can set one threshold value applied for the entire storage
system. When many-to-many connections are established between host bus
adapters and ports, you cannot set individual thresholds for prioritized WWNs.
For the system configuration of many-to-many connections between host bus
adapters and ports, see If Many-to-Many Connections Link HBAs and Ports.
For details on the system configuration of many-to-many connections between
host bus adapters and ports, see If Many-to-Many Connections Link HBAs and
Ports. This section explains operation procedures you can perform for host bus
adapters and the entire storage system.
Monitoring All Traffic between HBAs and Ports
When many-to-many connections are established between host bus adapters
(HBAs) and ports, you should make sure that all the traffic between HBAs and
ports is monitored.
To make all the traffics between host bus adapters and ports monitored:
1. Start Server Priority Manager.
The Server Priority Manager window is displayed.
2. Ensure that the WWN tab is displayed.
The two trees are displayed in the left side of the WWN tab. The upper-left
tree lists ports in the storage system.
3. Select All from the list at the top right corner of the window.
4. In the upper-left tree, double-click a port.
5. Double-click Non-Monitor below the specified port.
If there are any host bus adapters whose traffics with the specified port are
not monitored, those host bus adapters are displayed below Non-Monitor.
6. Right-click Monitor and then select Add WWN from the pop-up menu.
The Add WWN window is displayed. This window lets you add a WWN of a
host bus adapter to Monitor.
7. In the Add WWN window, specify the WWN and the SPM name.
