StorPortSetUnitAttributes function (storport.h)

The StorPortSetUnitAttributes routine registers attributes of a storage unit device with the Storport driver.

Syntax

ULONG StorPortSetUnitAttributes(
  [in] PVOID                HwDeviceExtension,
  [in] PSTOR_ADDRESS        Address,
  [in] STOR_UNIT_ATTRIBUTES Attributes
);

Parameters

[in] HwDeviceExtension

A pointer to the hardware device extension for the host bus adapter (HBA).

[in] Address

A STOR_ADDRESS structure that holds the storage unit device address. This parameter must not be NULL.

[in] Attributes

A STOR_UNIT_ATTRIBUTES structure with bits set to indicate the attributes supported for the unit device.

Return value

StorPortSetUnitAttributes returns one of the following status codes:

An invalid parameter can be any of the following:

• The HwDeviceExtension pointer is NULL.
• One or more reserved bits in Attributes are set.
• The unit address in Address is formatted incorrectly.
• A unit device is not found for the address given in Address.

Remarks

A miniport driver calls this routine to register the unit attributes with Storport during completion of an SRB containing a SCSIOP_INQUIRY command request. The bits in attributes are set based on the data returned from the adapter for the inquiry command. Storport issues an inquiry for the unit at Address during a bus enumeration.
