scsimgr - manage SCSI devices and device databases
/sbin/scsimgr -option [operands...]
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.
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 specified 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.
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.
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.
The following is the exit status when the command runs
from a program: Success. Failure.
Executable image. System configuration options. Contains
an entry to define /scsimgr utility to boot process.
