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: 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 device 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.  Request that the kernel scan the speci-
	      fied bus for devices.  If there have been device changes on the bus, the device special files are updated to  reflect  the  changes.
	      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.  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.
       The number of a bus. The number must be 0 or larger.  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 devices.

       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: Success.	Failure.

FILES

       Executable image.  System configuration options.  Contains an entry to define /scsimgr utility to boot process.
