Setting the SCSI Parameters

The following user configurable SCSI parameters can be set offline or online:

If the A7173A adapter is new and it is installed in a slot that has never been configured for a SCSI adapter, the adapter will be set to the following default settings:

Even if these default settings are appropriate for your configuration, HP recommends that you confirm the settings and make changes if necessary.

	IMPORTANT: When you replace an A7173A adapter, these conditions determine whether the previous settings will be applied to the replacement adapter: If the replacement adapter is new and has never been installed in a system, then the mpt driver will continue to use the SCSI parameter settings that are already configured for the slot. If the replacement adapter was previously installed in a different slot or system, then the SCSI parameter settings will not migrate to the new slot or system. HP recommends that you confirm the settings and make changes if necessary.

The SCSI parameters for A7173A adapters installed in HP 9000 systems can be confirmed or changed offline using the “SCSI” command, which can be accessed from the Boot Console Handler (BCH) menus, see “Using the BCH Menus on HP 9000 Systems” for details.

	NOTE: The bus width parameter cannot be set offline on rp24xx and rp54xx systems.

The SCSI parameters for A7173A adapters installed in HP Integrity systems can be confirmed or changed offline using the Extensible Firmware Interface (EFI), see “Using the EFI Utility on HP Integrity Systems”.

The SCSI parameters for an A7173A adapter installed in any supported HP-UX system can be confirmed or changed online using the mptconfig command, see “Using mptconfig for Online Configuration”.
