# This is a sample config file for tgt-admin.

# 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

|
|
# 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

|
# 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).
