Checking SCSI Bus Compatibility for HP A5159B Host Bus Adapters Installed In Itanium® Based Systems

At the EFI Shell prompt issue the drivers command as illustrated in the following screen display example:

Find the driver handle designation <drvr_handle>.

For the A5159B host bus adapter, the <drv_handle> designation will be in the "DRV" column that corresponds to the "LSI Logic Ultra SCSI Driver" listing in the "DRIVER NAME" column. In the preceding sample screen display, there are two versions of the LSI Logic Ultra SCSI Driver. The <driver_handle> designations that correspond to the two "LSI Logic Ultra SCSI Drivers" are 24 and 25.

Find the controller handle designation, <cntrl_handle>.

At the EFI Shell prompt, issue the drvcfg command as illustrated in the following screen display:

Shell> drvcfg
Configurable Components
  Drv[20]  Ctrl [1A] Lang [eng]
  Drv[20]  Ctrl [1B] Lang [eng]
  Drv[20]  Ctrl [1D] Lang [eng]
  Drv[20]  Ctrl [1E] Lang [eng]
  Drv[20]  Ctrl [23] Lang [eng]
  Drv[21]  Ctrl [22] Lang [eng]
  Drv[24]  Ctrl [27] Lang [eng]
  Drv[24]  Ctrl [2B] Lang [eng]
  Drv[24]  Ctrl [2C] Lang [eng]
  Drv[25]  Ctrl [26] Lang [eng]
  Drv[28]  Ctrl [29] Lang [eng]
  Drv[2D]  Ctrl [30] Lang [eng]
  Drv[2E]  Ctrl [2A] Lang [eng]
  Drv[2E]  Ctrl [2F] Lang [eng]
  Drv[48]  Ctrl [1F] Lang [eng]

From the output of drvcfg command, look for the line(s) where the NN in Drv[NN]is same as the <drvr_handle> for the driver(s) you are using. The 2nd column, Ctrl [NN], contains the corresponding <cntrl_handle>, where NN is the controller handle. For example, controller handle 27, 2B and 2C correspond to driver handle 24 and controller handle 26 corresponds to driver handle 25.

Once the driver handle and the controller handle are known, the SCSI parameters can be displayed and set for any driver and corresponding controller (host bus adapter) on the SCSI bus.

Enter the drvcfg -s <drvr_handle> <cntrl_handle> command at EFI shell prompt. A GUI screen will be displayed listing the controller (host bus adapter) that the controller handle corresponds to as illustrated in the following example (this is the 1st level screen):

LSI Logic Host Bus Adapters
Adapter     PCI  PCI     PCI         IRQ  NVM  LSI Logic  
            Bus  Device  Function              Control
<53C875     60   01      01>          0   Yes  Enabled

Press the [Enter] key. This will bring up the 2nd level screen containing the controller (host bus adapter) settings, as illustrated in the following example:

Adapter Properties
 
Adapter     PCI  PCI     PCI  
            Bus  Device  Function
53C875      60   01      01
 
         <Device Properties>
 
         Boot Support              [Enabled]
         SCSI Parity               [Yes]
         Host SCSI ID              [ 5]
         SCSI Bus Scan Order       [Low to High (0..Max)]
         Spinup Delay (Secs)       [ 2]
         Secondary Cluster Server  [Yes]
         Termination Control       [Auto]
         <Restore Defaults>

Use the arrow keys to highlight the different SCSI parameters

Use the - and + keys to change the highlighted SCSI parameter.

	NOTE: Only the "Host SCSI ID" and the "Secondary Cluster Server" parameters should be changed, if necessary. The "Secondary Cluster Server" should be set to "Yes" if more than one initiator is connected to the SCSI bus. The other SCSI parameters listed on the GUI are set at default values that should not be changed.

Press the [ESC] key to exit the 2nd level screen. Another GUI screen will appear with the following statements:

Adapter and/or device property changes have been made.
 <Cancel Exit>
 <Save changes then exit this menu>
 <Discard changes then exit this menu>
 Exit the Configuration Utility

Use the arrow keys to highlight your selection from the listed choices, then press the [ENTER] key to return to the 1st level GUI screen.

Press the [ESC] key at the 1st level GUI screen. Another GUI screen will appear with the following statements:

Are you sure you want to exit?
 <Cancel Exit>
 Save changes then exit this menu
 Discard changes then exit this menu
 <Exit the Configuration Utility>

Use the arrow keys to highlight your selection from the listed choices, then press the [ENTER] key to return to the EFI shell prompt.
