>One driver can potentially control several host adapters. For example
|
|
Advansys provide one Linux adapter driver that controls all adapters made
|
|
by that company - if 2 of more Advansys adapters are in 1 machine, then 1
|
|
driver controls both.
|
|
When ('driver_status' & SG_ERR_DRIVER_SENSE) is true the 'sense_buffer'
|
|
is also output. The 'driver_status' field has the following values whose
|
|
#defines mimic those which are only visible within the kernel (with the
|
|
"SG_ERR_" removed from the front of each define). A copy of these defines
|
|
can be found in sg_err.h (see the utilities section):
