Create an iSCSI target (server)

Environment:

• Fedora 9 x86_64
• Hostname: Example
• IP Address: 192.168.1.1

Yum install SCSI-target-utils

Chkconfig tgtd on

/Etc/init. d/tgtd start

Create a 10 Gb elastic volume, but do not allocate a real blank space
Dd If =/dev/Zero of =/test. img bs = 1 seek = 10g COUNT = 0

Set the 10 Gb quota disk space created by zookeeper to the iSCSI target test.

Iscsi target permission settings

Using CHAP authentication Authentication

Create a secret
Tgtadm -- Mode account -- op new -- user test -- password your_secret

Specify target information
Tgtadm -- Mode target -- op show

Target 1:
Iqn.2001-04.com. Example-test (Target 1 = -- tid
1)
System Information:
Driver: iSCSI
State: Ready
I _t nexus information:
Lun information:
Lun: 0
Type:
Controller
...
Lun: 1 (Lun 1 = -- Lun 1, disk starts from 1)
Type: Disk
...
Backing
Store:/path/to/disk. img
Account Information:
ACL information:
All

Specify the login commit (* commit) of Target 1)
Tgtadm -- Mode account -- op bind -- TID 1 -- user test

* Labels:
Scsi-target-utils-0.0-5.20080805snap.fc9.x86_64, scsi-target-utils-0.0-6.20080805snap.fc10.i386
The final result is that the initiator can use any of the regions created by tgtadm to generate login regardless of the target bind.

Set ACL Information

Only the lan ip Address can use target 1 (the last region is large I)
Tgtadm -- Mode target -- op bind -- TID 1-I 192.168.1.0/24

Unbind existing ACL Information
Tgtadm -- Mode target -- op unbind -- TID 1-I all
