NAME

devtab − information on the incremental load device driver

DESCRIPTION

The /etc/devtab file provides information on the device driver to be configured in a kernel that is currently being executed using the devattach command.  This file can be generated by system management personnel using the text editor.  The file indicates the device driver name, block device/character device major numbers, and object file name of the device driver.  An example of the /etc/devtab file is given below:

#
#nameblkchrfile
#
mdb 2c 10/sys/OBJ/md.o In the above example, the device driver name is md; the block device major number is 2; the character device major number is 10; and the object file name of the device driver is /sys/OBJ/md.o.  If devattach −a is executed, the object file is read in accordance with the /etc/devtab file and the incremental load is performed.  The /etc/devtab file is only read by the program, and no writing of the file is performed.  Proper generating and maintaining of this file is the duty of system management personnel.
