NAME
       iobind - bind a driver to a device

SYNOPSIS
       instance]

DESCRIPTION
       The  command  may  be  used to perform online unbinding of a device LUN
       hardware path from its current driver and binding a new driver  to  it.
       As part of the binding operation, the specified driver will be bound to
       the LUN hardware path and also to  its  corresponding  legacy  hardware
       paths.

       The  hardware  path  specified as the argument to the option must be of
       the form 64000/0x/0x.  The driver name specified with the  option  will
       be  bound  to  the  LUN and legacy hardware paths.  The optional option
       specifies an instance number to be assigned to  the  device  associated
       with the hardware path.	If this option is not used, the device will be
       assigned a new instance number in the new driver's class.  The optional
       forces  the  binding  to	 occur at the next reboot if it cannot be done
       online.

       The device must not be in use while the unbind operation is  performed.
       The  driver  must  support  online unbinding and binding.  If either of
       these requirements is false and the option is not given, the user  will
       be  asked  if the binding can take effect at the next reboot.  The user
       is given the option to proceed or not.

       If a driver supports online unbinding  and  binding,  then  after  com‐
       pletes,	a  device  will	 have  one of the following software states as
       shown by the command:

	      The specified driver was	successfully  bound  to	 the  hardware
	      path.

	      The specified driver cannot be used to claim the hardware at
			  the specified hardware path.

	      The device at the address is responding, but it is in an
			  error state.

	      The  device at the specified hardware path is no longer respond‐
	      ing.

	      The specified hardware path is locked.  Try again later.

	      The driver failed.

   Options
       recognizes the following options:

	      Force the binding even though a driver does not  support	online
	      unbinding
			  and  binding or the device is in use.	 In this case,
			  the binding will take effect at the next reboot.

	      The LUN hardware path of a device
			  must be of the form 64000/0x/0x.

	      The instance number to be assigned to the device.

	      The name of the driver that the LUN and  legacy  hardware	 paths
	      are to be bound to.

RETURN VALUE
       Exit values are:

       Successful completion.

       An error condition occurred.

EXAMPLES
       Unbind  the  driver  bound  to the device at hardware path and bind the
       device to Use the default instance number of the driver's class.

       Unbind the driver bound to the device at hardware  path	and  bind  the
       device to Assign it the instance number

       Do  a forced binding.  If the driver does not support online binding or
       the device is busy, the binding will be deferred till next reboot.

WARNINGS
       The and commands should not be run at the same time because  both  com‐
       mands  attempt  to  bind	 drivers.  In particular, there may be a short
       window while will leave a hardware path unbound.	 If runs  during  that
       window,	it may bind a different driver to that hardware path.  If this
       happens, must be executed again to bind the desired driver.

       may be executed only by the superuser.
