.SH DESCRIPTION
|
|
|
|
.B smartpqi
|
|
|
|
is a SCSI driver for Microsemi Smart Family controllers.
|
2017-11-13 06:54:29 +00:00
|
|
|
.SS Supported \f[BI]ioctl\fP\/() operations
|
|
|
|
For compatibility with applications written for the
|
|
|
|
.BR cciss (4)
|
|
|
|
and
|
|
|
|
.BR hpsa (4)
|
|
|
|
drivers, many, but not all of the
|
|
|
|
.BR ioctl (2)
|
|
|
|
operations supported by the
|
|
|
|
.B hpsa
|
|
|
|
driver are also supported by the
|
|
|
|
.B smartpqi
|
|
|
|
driver.
|
|
|
|
The data structures used by these operations
|
|
|
|
are described in the Linux kernel source file
|
|
|
|
.IR include/linux/cciss_ioctl.h .
|
|
|
|
.TP
|
|
|
|
.BR CCISS_DEREGDISK ", " CCISS_REGNEWDISK ", " CCISS_REGNEWD
|
|
|
|
These operations
|
|
|
|
all do exactly the same thing, which is to cause the driver to re-scan
|
|
|
|
for new devices.
|
|
|
|
This does exactly the same thing as writing to the
|
|
|
|
.BR smartpqi -specific
|
|
|
|
host
|
|
|
|
.I rescan
|
|
|
|
attribute.

.B CCISS_GETPCIINFO
|
2021-01-09 11:46:55 +00:00
|
|
|
This operation returns the PCI domain, bus,
|
2021-01-09 11:53:15 +00:00
|
|
|
device, and function and "board ID" (PCI subsystem ID).

The host

.I rescan
|
|
|
|
attribute is a write-only attribute.
|
|
|
|
Writing to this attribute will cause the driver to scan for new,
|
|
|
|
changed, or removed devices (e.g., hot-plugged tape drives, or newly
|
|
|
|
configured or deleted logical drives) and notify the SCSI mid-layer of

any changes detected.
