# This is a udev rules file that demonstrates how to get
# udev to set the symbolic link to the kernel block device name by reading the 
# customized LUN number.

# This udev rule supports only iSCSI devices.
# TODO: support PV and iSCSI devices.

# We use DEVPATH and ID_PATH variables to determine the LUN#
# The conversion from LUN# to friendly device name is simple-
# The format is /dev/oracleoci/oraclevdxx
# 2 becomes /dev/oracleoci/oraclevdb, 3 becomes /dev/oracleoci/oraclevdc and so on.
# The boot volumes are provided the device name of /dev/oracleoci/oraclevda.
