# This script generates and sends to stdout a set of udev.rules for use
|
|
# with all scsi block devices on your system. It creates a udev key NAME
|
|
# with prefix defaulting to "disk-", and appends the current kernel name
|
|
# and the udev kernel number (the partition number, empty for the entire
|
|
# disk).
|
|
#
|
|
# Managing these is probably better done via a gui interface.
|
|
#
|
|
# You can edit and append the output to your /etc/udev/udev.rules file.
|
|
# You probably want to to change names to be non-kernel defaults, so as to
|
|
# avoid confusion if a configuration change modifies /sys/block/sd*
|
|
# naming.
|
|
#
|
|
# /etc/scsi_id.config must be properly configured. If you are using this
|
|
# script, you probably want a single line enabling scsi_id for all
|
|
# devices as follows:
|
|
#
|
|
# options=-g
|
|
#
|
|
# The above assumes you will not attach block devices that do not
|
|
# properly support the page codes used by scsi_id, this is especially true
|
|
# of many USB mass storage devices (mainly flash card readers).
