The following structures and constants are defined in

|
|
|
.Pa dev/i2o/i2ovar.h .
|
|
|
|
|
Note that the header
|
|
|
|
|
.Pa dev/i2o/i2o.h
|
|
|
|
|
is a prerequsite and must therefore be included beforehand.

.It Dv IOPIOCPT (struct ioppt)
|
|
|
|
|
Submit a message to the IOP and return the reply. Note that the return
|
|
|
|
|
value of this ioctl is not affected by completion status as indicated by the
|
|
|
|
|
reply.

The minimum timeout value that may be specified is 1000ms. All other values
|
|
|
|
|
must not exceed the
|
|
|
|
|
.Nm
|
|
|
|
|
driver's operational limits.
|
|
|
|
|
.It Dv IOPIOCGLCT (struct iovec)
|
|
|
|
|
Return the
|
|
|
|
|
.Nm
|
|
|
|
|
driver's copy of the logical configuration table. This copy of the LCT
|
|
|
|
|
matches the current device configuration, but is not necessarily the latest
|
|
|
|
|
available version of the LCT. This ioctl may block while attempting to
|
|
|
|
|
acquire a lock on the LCT, and may fail if the acquisition times out.
|
|
|
|
|
.It Dv IOPIOCGSTATUS (struct iovec)
|
|
|
|
|
Request the latest available status record from the IOP. This special-case
|
|
|
|
|
ioctl is provided as the I2O_EXEC_STATUS_GET message does not post replies,
|
|
|
|
|
and can therefore not be safely issued using the IOPIOCPT ioctl.
|
|
|
|
|
.It Dv IOPIOCRECONFIG
|
|
|
|
|
Request that the
|
|
|
|
|
.Nm
|
|
|
|
|
driver scan all bus ports, retrieve the latest version of the LCT, and
|
|
|
|
|
attach or detach devices as necessary. Note that higher-level
|
|
|
|
|
reconfiguration tasks (such as logically re-scanning SCSI busses) will not
|
|
|
|
|
be performed by this ioctl.
