NAME

  scsimgr - manage SCSI	devices	and device databases

SYNOPSIS

  /sbin/scsimgr	-option	 [operands...]

OPTIONS

  The Update Options


  Use the following options to update device special files and the databases:

  -scan_all
      Request that the kernel scan all SCSI buses for devices. If there	have
      been device changes on any of the	buses, the on-disk database and	dev-
      ice special files	are updated to reflect the changes.


				       Note

	 The scan_all command should be	used with caution.  On systems with a
	 large number of SCSI buses, the -scan_all option can take a long
	 time to run and can affect the	performance of other processes
	 accessing SCSI	devices.

  -scan_bus bus=n
      Request that the kernel scan the specified bus for devices.  If there
      have been	device changes on the bus, the device special files are
      updated to reflect the changes.

  -scan_single bus=n target=n
      Request that the kernel scan the specified bus for a specific device.
      If there has been	a change to the	attributes of that device, the device
      special file for the device is updated to	reflect	the changes.

  -sync
      Synchronizes the information in the device special files and the kernel
      in-memory	database.

OPERANDS

  The following	operands are used in many of the command options.  Other
  operands are unique to individual options and	are defined with them.

  bus=n
      The number of a bus. The number must be 0	or larger.

  target=n
      The number of a target device. The range of the number is	0 to 15.


DESCRIPTION




				     Note

       See the hwmgr(8)	and dsfmgr(8) reference	pages for information on
       utilities that supersede	the scsimgr utility.

  The scsimgr utility automatically makes device special files for new dev-
  ices.

  The scan options stop	updating the device special files for a	device when
  they encounter an error.

EXIT STATUS

  The following	is the exit status when	the command runs from a	program:

  0 (Zero)
      Success.

  1   Failure.

FILES

  /sbin/scsimgr
      Executable image.

  /etc/sysconfigtab
      System configuration options.

  /sbin/bcheckrc
      Contains an entry	to define /scsimgr utility to boot process.
