You can ensure compatibility between the SCSI controller and
SCSI devices using the commands available for setting and displaying
the appropriate SCSI bus parameters, including SCSI IDs. The procedure varies depending on which system the HP A6828A
host bus adapter is installed in. For HP A6828A host bus adapters installed in PA-RISC based
systems, see . For HP A6828A host bus adapters installed in Itanium®-based systems, see . Setting
and Confirming SCSI Parameters for HP A6828A Host Bus Adapters Installed
in PA-RISC Based Systems | |
If the HP A6828A SCSI host bus adapter is installed in a supported
PA-RISC
based system, use the SCSI command to display and select SCSI parameters. The SCSI command is available from the boot menu displayed
after the test station has booted (if autoboot is disabled). In
the following illustration of the boot menu display, the SCSI command is emphasized with bold type:
Command Description

AUto [BOot|SEArch ON|OFF] Display or set the specified flag
BOot [PRI|ALT|<path> <args>] Boot from a specified path
BootTimer [time] Display or set boot delay time

The SCSI command can be used to display and set SCSI
bus parameters to ensure that the SCSI adapter is compatible with
the SCSI devices. Displaying
Transfer RatesTo display the SCSI transfer rate for an adapter using the SCSI command, use the following syntax: SCSI rate bus_number slot_number |
where - bus_number
Specifies the number of the
bus on which the adapter is installed. - slot_number
Specifies the number of the
slot the adapter is in.
For example: To display the SCSI
transfer rate for an adapter installed on bus 5 slot 2, issue the
following command: The command displays the following output: PCI device /5.2 = no limit |
To list transfer rates for all the
bus and slot numbers, issue the following command:
To set the SCSI transfer rate for an adapter using the SCSI command, use the following syntax: SCSI rate bus_number slot_number rate |
where - bus_number
Specifies the number of the
bus on which the adapter is installed. - slot_number
Specifies the number of the
slot the adapter is in. - rate
Specifies the adapter’s
transfer rate:
For example, to set the SCSI transfer rate for an adapter
installed on bus 5 slot 2 to Fast SCSI, issue the following command: To display the result, isssue the following command: The output is as follows: PCI device /5.2 = fast SCSI |
To display the initiator SCSI IDs for an adapter using the SCSI command, use the following syntax: SCSI init bus_number slot_number |
where - bus_number
Specifies the number of the
bus on which the adapter is installed. - slot_number
Specifies the number of the
slot the adapter is in.
For example: To display the SCSI
ID for an adapter on bus 5 slot 2, issue the following command: The command displays the following output: To list the SCSI IDs for all the
bus and slot numbers, issue the following command:
To set the initiator SCSI ID for an adapter using the SCSI command, use the following syntax: SCSI init bus_number slot_number ID_number |
where - bus_number
Specifies the number of the
bus on which the adapter is installed. - slot_number
Specifies the number of the
slot the adapter is in. - ID_num
Specifies the adapter’s
SCSI ID number.
For example, to set the SCSI ID for an adapter installed on
bus 5 slot 2 to 6, issue the following command: To display the result, issue the following command: The output is as follows: Setting

If the HP A6828A SCSI host bus adapter (HBA) is installed
in a supported Itanium®-based
system, use the following procedure to display and select SCSI parameters: At the EFI Shell prompt,
issue the drivers command as illustrated in the following example: |

Find the driver handle designation <drvr_handle>. For the A6828A HBA, the <drvr_ handle> designation will be in the DRV column that corresponds to the LSI Logic Ultra160 SCSI Driver listing in the DRIVER NAME column. In the preceding example, there are two versions of the LSI Logic Ultra160 SCSI Driver. The <drvr_handle> designations that correspond to the two LSI Logic Ultra SCSI Drivers are 20 and 21. Find the controller handle designation, <cntrl_handle>. At the EFI Shell prompt, issue the drvcfg command as illustrated in the following example: Shell> drvcfg

From the output of the 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 1A, 1B, 1D, 1E, and 23 correspond to driver handle 20, and controller handle 22 corresponds to driver handle 21. Once the driver handle and the controller handle are
identified, the SCSI parameters can be displayed and set for any
driver and corresponding controller (HBA) on the SCSI bus. Enter the drvcfg -s <drvr_handle> <cntrl_handle> command at EFI shell prompt. The Global Properties
screen containing a list of the controller (HBA) to which the controller
handle corresponds is displayed; refer to the following example: LSI Logic Host Bus Adapters
