- When the HBA is surprise removed, the Storport process does not release the devnode. Additionally, the Storport.sys driver does not use ReportLUN data after a CHECK condition occurs.
- The Storport process does not use the smaller of the sense info lengths when it unmaps the sense buffer. A sense info length is the length of failure information that is provided by the small computer system interface (SCSI) target after a CHECK condition occurs.
Note An example of a SCSI target is a disk failure.
- The Storport process calls the KeAcquireSpinLockAtDpcLevel() routine while Storport is below the deferred procedure call (DPC) dispatch level.
- The Store trace file (Stortrce.h) is not fixed for Microsoft Visual C++ .cpp files. Stortrce.h is an include file that has parameters to build the Storport.sys driver.
- The Storport.sys driver loses an I/O Request Packet (IRP). Therefore, the I/O and any dependent I/Os stop responding (hang).
- A bogus _SCSI_ADAPTER_BUS_INFO pointer definition of assertions is used for checked 64-bit Windows binaries.
- The StorPort.sys:IOCTL_SCSI_GET_INQUIRY_DATA I/O control (IOCTL) does not set the NextInquiryDataOffset field for the last logical unit number (LUN) to 0. Therefore, it does not signal the end of the LUN list as expected.
- The Storport set device queue depth is not used effectively. The Storport set device queue depth may be set to a default value despite attempts to override the configurations.
- The DbgValidateSrb (Xrb->Srb) and RaGetSrbExtensionSize (Xrb->Adapter) asserts do not exempt Windows Management Instrumentation (WMI) requests. WMI requests do not return the expected buffers.
- The initial LUN Reset is not called correctly.
