Subversion Repositories configs

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

# By default, tgt-admin looks for its config file in /etc/tgt/targets.conf

#

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

# This one includes other config files:

#include /etc/tgt/temp/*.conf

# Set the driver. If not specified, defaults to "iscsi".

#

# This can be iscsi or iser. To override a specific target set the

# "driver" setting in the target's config.

default-driver iscsi

#<target iqn.2008-09.com.example:iser>

#	Example: the next line would override default driver type.

#	driver iser

#<target>

# Set iSNS parameters, if needed

#iSNSServerIP 192.168.111.222

#iSNSServerPort 3205

#iSNSAccessControl On

#iSNS On

# Continue if tgtadm exits with non-zero code (equivalent of

# --ignore-errors command line option)

#ignore-errors yes

# 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).

#<target iqn.2008-09.com.example:server.target5>
