Note: If you are installing the IBM DS4000/FAStT FC-2 or FC2-133 HBA in a server that previously had a Qlogic QLA23xx Adapter, you will need to use the Updating the IBM DS4000/FAStT FC-2 FC2-133 HBA procedure to ensure that the correct device driver ql2300.sys is loaded for the IBM DS4000/FAStT FC-2 or FC2-133 Host Bus Adapters. ======================================================================= 3.4 Removing the IBM DS4000/FAStT FC-2 or FC2-133 Host Bus Adapter Driver ----------------------------------------------------------------------- You can not remove the IBM FC-2 or FC2-133 Host Bus Adapter Driver once it is installed in an Windows Server 2003 server. You can either disabling or removing the HBA from the server if you do not have any more needs for the IBM FC-2 or FC2-133 Host Bus Adapter. To remove an HBA: Turn off your computer and remove the device from your computer according to the manufacturers instructions. At a later time, if you reinstall the same type of HBA in the server, it will be automatically recognized and installed with the saved driver. Note: It is best practice to use the Add/Remove hardware function to remove/uninstall the HBA(s) before you remove it from the server. ======================================================================= 4.0 Configuration Information ----------------------------- The configurable driver parameters are divided into System Registry Parameters and NVRAM Parameters sections. ======================================================================= 4.1 NVRAM Parameters --------------------- The default adapter NVRAM settings is optimized for Windows Server 2003 environments. However, modifications to the NVRAM settings many be required depending on a given server configuration. You can configure the adapter NVRAM settings using the Fast!UTIL utility. To access Fast!UTIL utility, press Ctrl+Q during host BIOS initialization. Refer to the IBM DS4000/FAStT FC-2 Host Adapter Installation and User's Guide or IBM DS4000/FAStT FC2-133 Host Adapter Installation and User's Guide for additional information on adapter NVRAM settings. 4.1.1 Hard Loop ID ------------------ It is recommended that you set different Hard Loop IDs for each IBM DS4000/FAStT FC-2 or FC2-133 HBA port in a single Host or in each Node in a cluster. For example, in Host Adapter Settings, set the Hard Loop ID to 125 for the first host in a cluster and set the Hard Loop ID to 124 for the other host in the cluster. If you do not assign different Hard Loop IDs, the Fibre Channel protocol will automatically assign soft-loop IDs when their is a hard-loop ID conflict. 4.1.2 Port Down Retry Count --------------------------- From the Advanced Adapter Settings, change the Port Down Retry Count to 70 (if you have more than 5 devices on the fibre channel loop attached to the IBM DS4000/FAStT FC-2 Host Adapter). Fibre Channel Host Adapters and Storage Subsystems are counted as fiber channel devices. You can configure the adapter using the Fast!UTIL utility. 4.1.3 Data Rate --------------- This setting determines the data rate. The default setting is 2, which allows the Host Adapter port to negotiate for the best connection speed. In certain cases, the adapter data rate must be locked at either 1Gbps or 2Gbps. Use the FAST!Util utility to change this setting in the Extended Firmware Setting window. ======================================================================= 4.2 System Registry Parameters ------------------------------ WARNING: - Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Use Registry Editor at your own risk. - Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedt32.exe. Below is a description of the registry parameters used by the driver: 4.2.1 MaximumSGList ------------------- Windows Server 2003/2000 includes an enhanced scatter/gather list support for doing very large SCSI I/O transfers. Windows NT supports up to 256 scatter/gather segments of 4096 bytes each, allowing transfers up to 1048576 bytes. NOTE: The oemsetup.inf file has been updated to automatically update the registry to support 256 scatter/gather segments. This is a change from previous releases of the driver. In the previous releases, this setting was set at 65. If you want to change this value, use the following procedure: 1. Click Start -> Run. When the Run window opens, enter REGEDT32 and click open to start the Windows Server 2003 registry modification program. 2. Select HKEY_LOCAL_MACHINE and follow the tree structure down to the IBM driver as follows: HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> Services -> Ql2300 -> Parameters -> Device 3. Double-click: MaximumSGList:REG_DWORD:0x21 4. Enter a value from 16 to 255 (0x10 hex to 0xFF). A value of 255 (0xFF) enables the maximum 1 MByte transfer size. Setting a value higher than 255 results with the default of 64K transfers. The default value is 255 (0xFF). 5. Click OK. 6. Exit the Registry Editor, then shutdown and reboot the system. 4.2.2 Number Of Requests ------------------------ Windows Server 2003/2000 supports the NumberOfRequests registry parameter to specify the maximum number of outstanding requests per adapter. When the IBM driver is installed, the registry will be automatically updated with this parameter set to a value of 150 (0x96). CAUTION: DO NOT increase this parameter above 150. Doing so can result in a system failure. 4.2.3 Fabric Supported ---------------------- By default, the driver supports Fibre Channel fabric (switch). Should you wish to disable fabric support please use the following procedure: 1. Click Start -> Run. When the Run window opens, enter REGEDT32 and click open to start the Windows Server 2003 registry modification program. 2. Select HKEY_LOCAL_MACHINE and follow the tree structure down to the IBM driver as follows: HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> Services -> Ql2300 -> Parameters -> Device 3.

Double-click: DriverParameters:REG_SZ:MSCS=2;UseSameNN=1 4. If the string FCTape= does not exist, append to end of string; FCTape=1 5. If the string FCTape=0 exists, change the value from 0 to 1. 6. Click OK. 7. Exit the Registry Editor, then shutdown and reboot the system. 4.2.6 MSCS ---------- In SAN configuration, the driver is required to handle RSCN efficiently to avoid disruption of I/O because of unnecessary re-logins. However, in Microsoft Cluster environment, it is necessary for the driver performs re-logins because the shared storage subsystems may be reset by other initiators through a ResetBus operation. The driver parameter MSCS is designed to accommodate the conflicting needs on how to handle RSCN in both environments. It accepts three values: Value RSCN Handling Environment ----- ------------------------- 0 Upon receiving RSCN, performs logins to SAN devices only if necessary 1 Upon receiving RSCN, always performs logins Cluster 2 Upon receiving RSCN, attempts to detect whether the system is running in the Cluster SAN/Cluster environment during boot. If yes, always performs logins upon receiving RSCN. If not, performs logins only if necessary By default, the oemsetup.inf file is set up to have MSCS set to 2. To change the driver to handle RSCN differently, use the following procedure: 1. Click Start -> Run. When the Run window opens, enter REGEDT32 and click open to start the Windows Server 2003 registry modification program. 2. Select HKEY_LOCAL_MACHINE and follow the tree structure down to the IBM driver as follows: HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> Services -> Ql2300 -> Parameters -> Device 3. Double-click: DriverParameters:REG_SZ:MSCS=2;UseSameNN=1 4. If the string MSCS= does not exist, append to end of string; MSCS=n where n = 0, 1, or 2. 5. If the string MSCS= exists, change the value to the desired value. 6. Click OK. 7. Exit the Registry Editor, then shutdown and reboot the system. 4.2.7 UseSameNN --------------- By default, if you have multiple Fibre Channel HBAs on the same system, the driver will assign the world wide node name obtained from the first HBA to the rest of the HBAs. If you wish to have each HBAs to assume the world wide node name based on its own NVRAM content, you need to disable this feature by setting the UseSameNN parameter to 0. Please use the following procedure to change the UseSameNN parameter: 1. Click Start -> Run. When the Run window opens, enter REGEDT32 and click open to start the Windows Server 2003 registry modification program. 2. Select HKEY_LOCAL_MACHINE and follow the tree structure down to the IBM driver as follows: HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> Services -> Ql2300 -> Parameters -> Device 3. Double-click: DriverParameters:REG_SZ:MSCS=2;UseSameNN=1 4. If the string UseSameNN= does not exist, append to end of string; UseSameNN=0 5. If the string UseSameNN=1 exists, change the value from 1 to 0. 6. Click OK. 7. Exit the Registry Editor, then shutdown and reboot the system. 4.2.8 Buschange --------------- To ensure proper operation when the HBA is used in a DS4000 Storage Server environment, the buschange parameter must be set to 0. The default setting of the buschange parameter when it is not specified is 2. To set buschange parameter to 0, use the following procedure: 1. Click Start -> Run. When the Run window opens, enter REGEDT32 and click open to start the Windows Server 2003 registry modification program. 2. Select HKEY_LOCAL_MACHINE and follow the tree structure down to the IBM driver as follows: HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> Services -> Ql2300 -> Parameters -> Device 3. Double-click: DriverParameters:REG_SZ:UseSameNN=1 4. If the string buschange= does not exist, append to end of string; buschange=0 5. If the string buschange= exists, change the value to the desired value. 6. Click OK. 7. Exit the Registry Editor, then shutdown and reboot the system. 4.2.9 Disk TimeOutValue (in secs) --------------------------------- Note: In certain DS4000 storage server maximum configuration installation, it may be required to set the TimeOutValue to 120 (decimal.) Changing this value to a higher value might affect your application especially when it requires the disk IO completion acknowledgement within a certain amount of time. ATTENTION: To ensure the driver function properly, the driver sets the system related registry - Disk TimeOutValue - to 60. When installing clustering service, the cluster install wizard changes this value to 20. You must change this value back to 60(0x3c) to ensure proper operation of the HBA when connecting to DS4000 storage servers. To modify this registry value, use the following procedure: 1. Click Start -> Run. When the Run window opens, enter REGEDT32 and click open to start the Windows Server 2003 registry modification program. 2. Select HKEY_LOCAL_MACHINE and follow the tree structure down to the Disk TimeOutValue as follows: HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> Services -> Disk 3. Double-click: TimeOutValue:REG_DWORD:0x3c 4. If the value is not 60 (0x3c), change it. 5. Click OK. 6. Exit the Registry Editor, then shutdown and reboot the system. ======================================================================= 4.3 Configuration Notes ------------------------ Support for more than 8 LUNs ---------------------------- Windows Server 2003/2000 uses the ANSI-approved version field of the Inquiry data returned by the target device to determine whether it should support only 8 LUNs or 255 LUNs. If the field indicates that the target device complies to SCSI-3 standard, the operating system will enable more than 8 LUNs support. Otherwise, it will support only 8 LUNs. Enhanced Loop ID ---------------- Of 0 - FFh Loop Ids, some are preallocated for special functions and are not available for use by devices: Loop IDs Functions -------- ---------- 7Eh FL_Port (S_ID=FFFFFEh) 7Fh Switch Fabric Controller (S_ID=FFFFFDh) 80h Switch Name Server (S_ID=FFFFFCh) 81h Switch Embedded Port (FFFc4xh) used for FC-4 probing (Brocade only) FFh IP Broadcast Connection options ------------------ The following connection options are supported: Value Connection ----- ----------------- 00 Start in loop mode, by transmitting Lip F7F7 01 Start in point-to-point mode, by transmitting NOS/OLS 02 Start in loop mode first, then switch to point- to-point mode if NOS is detected. The connection option is currently stored in the NVRAM and can be changed through the Fast!Util. The default value of the connection mode is 2. Fibre Channel Tape support -------------------------- There are two ways to enable Fibre Channel (FC) tape support, the first method is to enable the FC tape support NVRAM setting in the HBA Extended Firmware Setting window. You can configure the FC HBA NVRAM settings using the FC HBA Fast!UTIL utility or the IBM FAStT Management Suite Java (FAStT MSJ) program. To access Fast!UTIL utility, press Ctrl+Q during host BIOS initialization (see section 4.1.) The second way is to set the Fibre Channel Tape Driver Parameters in the system registry to 1. Link Down Timeout BIOS setting ------------------------------- The IBM FC-2 and FC2-133 FC HBA Link Down Timeout BIOS setting should be set to 30 when the Microsoft Windows servers that the FC HBAs are in are part of a MSCS configuration. You can configure the FC HBA NVRAM settings using the FC HBA Fast!UTIL utility or the IBM FAStT Management Suite Java (FAStT MSJ) program. To access Fast!UTIL utility, press Ctrl+Q during host BIOS initialization.
