用Tgtadm 在EL/ RHEL5上创建一个iSCSI目标
适用于：
Linux Kernel - Version: 5.3
Linux Itanium
Linux x86-64
目标：
如何用tgtadm和tgtd建立一个iSCSI目标。
对于这个例子，以下是必要的：
scsi-target-utils
the Partiton /dev/hdb1
Enterprise Linux / Redhat Enterprise Linux 5 Update 3
解决方案：
创建一个永久的配置
1，Install scsi-target-utils
# up2date scsi-target-utils
Name Version Rel

scsi-target-utils 0.0 5.20080917snap.el5x86_64

Name Version Release
--------------------------------------------------------------
perl-Config-General 2.40 1.el5
2，Start the tgtd Service
# /etc/init.d/tgtd start
Starting SCSI target daemon: [ OK ]
3，在/etc/TGT/targets.conf创建一个条目，我们使用的是iSCSI目标作为分区/dev/hdb1
# cat /etc/tgt/targets.conf
<target iqn.2001-04.com.mydomain:storage.disk1>
backing-store /dev/hdb1
incominguser disk1user 123456
outgoinguser disk1user 12345
</target>
4，Enable tgtd at boot
# chkconfig tgtd on
5，禁用的iptables（或配置iptables允许TCP端口3260）
# /etc/init.d/iptables stop,
# chkconfig iptables off
6，重启tgtd或系统
7，验证配置
# tgtadm --lld iscsi --op show --mode target
Target 1: iqn.2001-04.com.mydomain:storage.disk1

8.与您的iSCSI客户端的新创建的目标连接，可以使用的指令Note.473179.1。
手动添加上飞行的目标
Start the tgtd Service
# /etc/init.d/tgtd start
Starting SCSI target daemon: [ OK ]
Create a Target
# tgtadm --lld iscsi --op new --mode target --tid 1 -T iqn.2001-04.com.mydomain:storage.disk1
Add a Partition to the Target, we are using /dev/hdb1 as the Partition as the iSCSI Target
[root@iscsi ~]# tgtadm --lld iscsi --op new --mode logicalunit --tid 1 --lun 1 -b /dev/hdb1
Allow all iSCSI Initiators to connect to the newly created Target
# tgtadm --lld iscsi --op bind --mode target --tid 1 -I ALL
Verify your Configuration
# tgtadm --lld iscsi --op show --mode target
Target 1: iqn.2001-04.com.mydomain:storage.disk1
System information:
Driver: iscsi
State: ready
I_T nexus information:
LUN information:
LUN: 0
Type: controller
SCSI ID: deadbeaf1:0
SCSI SN: beaf10
Size: 0 MB
Online: Yes
Removable media: No
Backing store: No backing store
LUN: 1
Type: disk
SCSI ID: deadbeaf1:1
SCSI SN: beaf11
Size: 2509 MB
Online: Yes
Removable media: No
Backing store: /dev/hdb1

请注意，此配置是不是永久性的，tgtd是重新启动或重新启动服务器时，将丢失。
此外，没有用户/密码是需要与此配置。
