# iSCSI configuration file - see iscsi.conf(5)

# Authentication Settings
# -----------------------
# You may configure a default Username and Password to use for CHAP
# authentication by specifying the Global username and password parameters
# in the format as mentioned below. These entries will need to precede any
# "DiscoveryAddress" entries if authentication needs to be enabled for all the
# iSCSI targets.
#
# Example:
#
#Username=alice
#Password=nty57nbe
# or
#OutgoingUsername=alice
#OutgoingPassword=nty57nbe
#
# The "OutgoingUsername" will specify the username to be sent to the target
# for login authentication. The "OutgoingPassword" is the CHAP secret password
# to be used when sending challenge responses to the target.
#
# You may configure CHAP authentication settings that will apply to every
# target discovered at a particular address by adding "OutgoingUsername=u"
# and "OutgoingPassword=p" entries indented below the "DiscoveryAddress"
# entry they apply to.
#
# Example:
#
#DiscoveryAddress=192.168.10.94

DiscoveryAddress=10.48.69.242 Continuous=yes

!--- Configure the IP address of the GE interface that accepts iSCSI request from your host. # LUN Settings
# ------------
# The LUN settings can be specified per TargetName or for all the targets
# whose TargetNames are mentioned in the configuration file. If no TargetName
# is present in the configuration file, the lun(s) will be configured for
# all the available iSCSI targets.
# The LUN settings can be specified in the following 3 formats:-
# LUN=
        
        
          # LUNs= 
         
           # LUNs= 
          
            # # The range of luns to be configured can be specified using a hyphen. A comma # separated list of luns can also be used. # Example: # #LUN=35 #LUNs=39-47 #LUNs=200,49,0,31 
           LUNs=0-255 # # LUNs can be configured per TargetName as mentioned in the format below. # #TargetName=iqn.1987-05.com.cisco:00.0d1d898e8d66.t0 # LUNs=39-47 # Continuous Discovery settings # ----------------------------- # You can configure discovery session to be kept open by setting # "Continuous" key to "yes" (default setting). Set Continuous=no to close # the discovery session, once the discovery is over. # #Continuous=yes #Continuous=no # # This parameter can be specified per DiscoveryAddress configuration. # #DiscoveryAddress=10.77.13.52 # Continuous=yes

!--- The iSCSI driver discovery daemon process looks up each discovered target !--- in the /var/lib/iscsi/bindings file. If an entry exists in the file for the !--- target, the corresponding SCSI target ID is assigned to the target. If !--- no entry exists for the target, the smallest available SCSI target ID !--- is assigned and an entry is written to the /var/lib/iscsi/bindings file for !--- this target.

!--- Note that the /var/lib/iscsi/bindings file will permanently contain entries !--- for all iSCSI targets ever logged into from this host. If a target is !--- no longer available to a host, you can manually edit the file and remove !--- entries so that the obsolete target no longer consumes a SCSI target ID. !--- If you know the iSCSI target name of a target in advance, and you want !--- it to be assigned a particular SCSI target ID, you can add an entry !--- manually. You should stop the iSCSI driver before editing the !--- /var/lib/iscsi/bindings file.

!--- To manually start the iSCSI driver, enter /etc/init.d/iscsi start

!--- To manually stop the iSCSI driver, enter /etc/init.d/iscsi stop
