sdimkdev(ADM)

sdimkdev -- generate device nodes for Storage Device Interface (SDI) subsystem

Synopsis

/sbin/sdimkdev [-fis] [-d filename]

Description

sdimkdev(ADM) reads the Equipped Device Table (EDT built by the SDI drivers and makes any device nodes needed for access to the disk, tape, and SCSI controllers that are present on the system. Device nodes are always created for the first 16 slices. Because these device nodes are created for each device and are unique to that device type, template files are used to specify the device naming conventions. The location of the template files is specified in a target controller index file that can be supplied as a command-line argument. By default, anytime a new device is detected, a message describing the device is printed on standard output. When more than 16 slices are used, device nodes are created for each additional slice in use. These device nodes are created from the VTOC rather than from the template files.

sdimkdev keeps a record of the EDT from invocation to invocation in the /etc/scsi/sdi_edt file. If the EDT obtained by sdimkdev during execution is identical to the one in /etc/scsi/sdi_edt, no action is taken and sdimkdev exits. If the EDT has changed since the last invocation, sdimkdev checks every node for every device in the EDT and creates any missing nodes.

Options

sdimkdev takes the following options:

-f: Forces sdimkdev to run at a time other than from init(ADM). sdimkdev is designed to be run from init; to force its execution at any other time, you must use the -f option.
-i: Forces sdimkdev to ignore the existing record of this machine's configuration in /etc/scsi/sdi_edt and update all SDI device nodes, as if a new device had been added to the system.
-s: Suppress the standard output message from sdimkdev indicating that new device nodes were just created for a device.
-d filename: Use filename instead of /etc/scsi/tc.index to determine which template file to use for each device.

Return values

sdimkdev exits with a return code of zero when it detects new devices on the system. If there are no new devices since the last time sdimkdev was executed, it exits with a return code of one. If an error is detected, it exits with a return code other than zero or one.
