Iscsiadm command returns error 'no records found'
Hi there, I'm currently working on an exercise to connect to a Windows iscsi target via a Red Hat initiator machine. I'm using Windows Server 2012 and Red Hat Enterprise Linux v7.1
I have created the target on the Windows Server box and the two devices can communicate with each other. Verified through ping. My instructions from the Red Hat machine are as follows;
Open a terminal window and enter the following command;
iscsiadm --mode discovery --type sendtargets --portal 192.168.1.200
[I first did this and the command returned nothing. I then invoked the sudo command and was able to get the target iqn, which is "iqn-1991-05.com.microsoft:srv2012-1-localservers-target"]
My next steps are to enter the following;
iscsiadm --mode node --targetname the_target_iqn --portal 192.168.1.200 --login
[Unfortunately this just returns 'no records found']
I'm not exactly sure what I'm doing wrong. I have followed the instructions and made sure to check all the spacing and syntax. Although, it appears something isn't right.
Does anybody have any ideas?
Thanks

tgt-admin
TGT-ADMIN(8) TGT Configuration Tool TGT-ADMIN(8)
NAME
tgt-admin - Linux SCSI Target Configuration Tool.
SYNOPSIS
tgt-admin -[OPTION]...
DESCRIPTION
tgt-admin is a utility which allows a persistent configuration of targets and luns.
It uses tgtadm commands to create, delete and show targets.
OPTIONS
-e, --execute
read /etc/tgt/targets.conf and execute tgtadm commands.
if target already exists it will be deleted and a new instance will be created with the new parameters instead.
-d, --delete
delete all the targets
-s, --show
show all the targets
-f, --force
don't exit on tgtadm errors
-p, --pretend
only print tgtadm options
-v, --verbose
increase verbosity (no effect in "pretend" mode)
-c, --conf <conf_file>
specify an alternative configuration file instead of /etc/tgt/target.conf, which is the default.
-h, --help
display a list of available options and exits
CONFIGURATION FILE SYNTAX
The defualt configuration file is: /etc/tgt/target.conf. It defines all the targets and their properties.
The configuration file is in XML format and uses tags. Configuration file contains several target blocks, where each block contains tar-
get's proerties such as storage devices, initator ACL and authorization information. You can include other config files using:
include /etc/tgt/xen/*.conf.
There are 2 types of storage devices:
backing-store - defines a virtual device on the target.
direct-store - defines a direct mapped device with the same properties as the physical device (such as VENDOR_ID , SERIAL_NUM, etc.)
initiator-address - allows connections only from the specify IP address. defaults to ALL if no "initiator-address" is specified
incominguser - define iscsi incoming authentication setting. if no "incominguser" is specified, it is not used.
outgoinguser - define iscsi outgoing authentication setting. if no "outgoinguser" is specified, it is not used.
example for a configuration file:
<target iqn.2007-04.com.example:san.monitoring>
backing-store /dev/san/monitoring
# if no "incominguser" is specified, it is not used
incominguser backup secretpass12
# defaults to ALL if no "initiator-address" is specified
initiator-address 192.168.1.2 </target>
<target iqn.2007-02.com.example:san.xen1>
backing-store /dev/san/xen1-disk1 # LUN1
direct-store /dev/san/xen1-disk2 # LUN2
initiator-address 192.168.1.2 # Allowed IP
initiator-address 192.168.5.6 # Allowed IP
incominguser user1 secretpass12
incominguser user2 secretpass23
outgoinguser userA secretpassA </target>
<target iqn.2007-02.com.example:san.xen2>
backing-store /dev/san/xen2 </target>
<target iqn.2007-06.com.example:san.vmware1>
backing-store /dev/san/vmware1 </target>
FILES
/etc/tgt/target.conf
