# This is a sample config file for tgt-admin.
# The files ending with '.conf' in this directory will be included.

# The "#" symbol disables the processing of a line.


# Sample target with one LUN only. Defaults to allow access for all initiators:

#<target iqn.2008-09.com.example:server.target1>
#    backing-store /dev/LVM/somedevice
#</target>


# Similar, but we use "direct-store" instead of "backing-store".
# "direct-store" reads drive parameters with sg_inq command and sets them to
# the target.
# Parameters fatched with sg_inq are:
# - Vendor identification
# - Product identification
# - Product revision level
# - Unit serial number (if present)
# We also specify "incominguser".

#<target iqn.2008-09.com.example:server.target2>
#    direct-store /dev/sdd
#    incominguser someuser secretpass12
#</target>


# An example with multiple LUNs, disabled write-cache (tgtd enables write-cache
# by default) and vendor identification set to "MyVendor"

#<target iqn.2008-09.com.example:server.target3>
#    backing-store /dev/LVM/somedevice1	# Becomes LUN 1
#    backing-store /dev/LVM/somedevice2	# Becomes LUN 2
#    backing-store /dev/LVM/somedevice3	# Becomes LUN 3
#    write-cache off
#    vendor_id MyCompany Inc.
#</target>


# Similar to the one above, but we fetch vendor_id, product_id, product_rev and
# scsi_sn from the disks.
# Vendor identification (vendor_id) is replaced in all disks by "MyVendor"

#<target iqn.2008-09.com.example:server.target4>
#    direct-store /dev/sdb	# Becomes LUN 1
#    direct-store /dev/sdc	# Becomes LUN 2
#    direct-store /dev/sdd	# Becomes LUN 3
#    write-cache off
#    vendor_id MyCompany Inc.
#</target>


# Note that "first-device-first-lun numbering" will work only for simple
# scenarios above, where _only_ direct-store _or_ backing-store is used.
# If you mix backing-store and direct-store, then all backing-store entries
# are processed before direct-store-entries.

#<target iqn.2008-09.com.example:server.target4>
#    direct-store /dev/sdb	# Becomes LUN 3
#    backing-store /dev/sdc	# Becomes LUN 1
#    direct-store /dev/sdd	# Becomes LUN 4
#    backing-store /dev/sde	# Becomes LUN 2
#</target>


# Even more complicated example - each device has different parameters.
# You can use indentation to make the config file more readable.
# Note that LUNs will be assigned more or less randomly here (and still
# backing-store get LUNs assigned before drect-store).
# You can specify multiple mode_page parameters (they are commented out
# in this example).
# Note that some parameters (write-cache, scsi_sn) were specified "globally".
# "Global" parameters will be applied to all LUNs; they can be overwritten
# "locally", per LUN.
# If lun is not specified, it will be allocated automatically (first available).
