The storage connects directly with the Emulex LP1150 HBA board via the DAS network, causes the initiator is unconnected

Issue Description
Product and version:
•S5500T V100R001 V100R002
•S5600T V100R001 V100R002
•S6800T V100R001 V100R002
The operating system of the application server: Windows Server 2008 R2 Enterprise
The HBA board is: Emulex LP1150 (the driver program: 5.2.41.002; FC HBA Firmware version: 2.10A10; FC HBA BIOS version: 1.70a3)
The storage device and application server use the DAS network, as the figure 1 displayed:
Figure 1 DAS network:

In this network environment, execute the following operations, see from the storage, we find the host initiator’s statuses are both “unconnected”, as the figure 2 displayed:
Modify the FC host port of the storage and the speed or port mode of the host HBA card.
Plug out and plug in the fiber cable between the storage and the application server.
Figure 2. The initiator’s status is “unconnected”
Alarm Information
None
Handling Process
1. Login in the CLI, run the “setportparam” command and change the FC host port’s delay time to send the “FLOGI” command as 500 μs.
The command format:
“setportparam -c controller ID -b subboard ID -p port ID -d flogin delay times”
Where,
“-c controller ID” denotes the ID of the controller whose FC host port has connected with the Brocade 825 FC HBA card.
“-b subboard ID” denotes the ID of the interface module whose FC host port has connected with the Brocade 825 FC HBA card.
“-p port ID” denotes the ID of the host port connected with the Brocade 825 FC HBA card.
“-d flogin delay times” denotes the delay time of sending the FLOGI command. For example, “” denotes that modifying the interface module ID of the controller as 1, and the FC host port whose ID is 1 when send the FLOGI command, its delay time is 500 μs.
2. Login in the ISM, unfold the storage device node which needed to be operated and select the “device information > port” at the navigation tree.
3. Select the FC host port needed to be modified and right-click this FC host port.
4. Select “modify” in the ejecting shortcut menu
5. Modify the “configuration mode” of the FC host port as “point to point” in the ejecting dialog box “modify the FC port information”.
Root Cause
The driver program of the Emulex LP1150 HBA card doesn’t accord with the protocol standard, it leads to the initiator’s status on the storage is “unconnected”.
Suggestions
After the storage has connected with the application server, please don’t modify the configuration mode or speed of the FC host port.
