Configuring the QLogic HBA for hosts that run the Windows Server operating system

After you install the QLogic HBA and the device driver on hosts that run a Microsoft Windows Server operating system, you must configure the HBA.

For more information about supported QLogic models, see the following Web sites:

For Lenovo Storage V3700 V2 and Lenovo Storage V3700 V2 XP: https://datacentersupport.lenovo.com/us/en/products/storage/lenovo-storage/v3700v2/6535
For Lenovo Storage V5030: https://datacentersupport.lenovo.com/us/en/products/storage/lenovo-storage/v5030/6536

To configure the HBA BIOS, either use the QLogic HBA manager software or reboot into the Fast!UTIL tool. Configure the following settings:

Host Adapter BIOS: Disabled (unless the machine is configured for SAN Boot)
Adapter Hard Loop ID: Disabled
Connection Options: 1 - point to point only
LUNs Per Target: 0
Port Down Retry Count: 15

Set the execution throttle to a suitable queue depth for your environment, for example, a value of 100. For more information about the execution throttle and queue depth, see http://support.qlogic.com/SupportCenter/articles/Question_Answers/2718.

If you are using subsystem device driver (SDD) 1.6 or later, set Enable Target Reset to No. See Table 1 to include the required parameters for the registry key.
