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 dev-
ice 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.
-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.
Synchronizes the information in the device special files and the kernel
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 dev-
The scan options stop updating the device special files for a device when
they encounter an error.
