Constructor & Destructor Documentation

◆ linux_megaraid_device()

Member Function Documentation

◆ autodetect_open()

smart_device * os_linux::linux_megaraid_device::autodetect_open ( )
overridevirtual

Open device with autodetection support.

May return another device for further access. In this case, the original pointer is no longer valid. Default implementation calls 'open()' and returns 'this'.

Reimplemented from smart_device.

Definition at line 1108 of file os_linux.cpp.

◆ close()

bool os_linux::linux_megaraid_device::close ( )
overridevirtual

Close device, return false on error.

Reimplemented from os_linux::linux_smart_device.

Definition at line 1209 of file os_linux.cpp.

void *  cdb,
int  dataLen,
void *  data,
int  senseLen,
void *  sense,

private

Definition at line 1334 of file os_linux.cpp.

◆ megasas_cmd()

void *  cdb,
int  dataLen,
void *  data,
int  senseLen,

int  direction 
)
private

Definition at line 1273 of file os_linux.cpp.

◆ open()

bool os_linux::linux_megaraid_device::open ( )
overridevirtual

Open device, return false on error.

Reimplemented from os_linux::linux_smart_device.

Definition at line 1149 of file os_linux.cpp.

◆ scsi_pass_through()

bool os_linux::linux_megaraid_device::scsi_pass_through ( scsi_cmnd_io iop)
overridevirtual

SCSI pass through.

Returns false on error.

Implements scsi_device.
