标题: Linux 环境下iSCSI 的配置

环境：
#uanme -a
Linux Fedora 2.6.18-1.2798.fc6

N3700-B> version
Data ONTAP Release 7.2.3: Thu Jul  5 10:33:14 PDT 2007 (IBM)
步骤：
1:下载iSCSI initiator for Linux platform
  下载地址：http://rpmfind.net/linux/rpm2html/search.php?query=iscsi-initiator-utils
iscsi-initiator-utils-6.2.0.865-0.2.fc7.i386.rpm
2:安装
  #rpm -ivh iscsi-initiator-utils-6.2.0.865-0.2.fc7.i386.rpm
3:启动iSCSI 服务
  #service iscsi start
4:iSCSI 配置文件
  /etc/iscsi/initiatorname.iscsi
  /etc/iscsi/iscsid.conf
5:发现target
  #iscsiadm --mode discovery --type sendtargets --portal 192.168.222.252
6:登录到target
  #iscsiadm --mode node --targetname iqn.1986-03.com.ibm:sn.99932701 --portal 192.168.222.252:3260 --login
7：在NAS上面创建igroup
  #igroup create -i -t linux iscsigroup1 iqn.2005-03.com.max:01.b98cc8
8：创建LUN
  N3700-B> lun create -s 35m -t linux /vol/iscsivol/iscsiqtree/iscsilun3
9：将LUN map 给 igroup
  lun map /vol/iscsivol/iscsiqtree/iscsilun3 iscsigroup1 1
10:查看map的信息
   N3700-B> lun show -m
LUN path                         Mapped to       LUN ID  Protocol
-----------------------------------------------------------------------
/vol/iscsivol/iscsiqtree/iscsilun0  iscsigroup0          0    iSCSI
/vol/iscsivol/iscsiqtree/iscsilun1  iscsigroup0          1    iSCSI
/vol/iscsivol/iscsiqtree/iscsilun2  iscsigroup1          0    iSCSI
/vol/iscsivol/iscsiqtree/iscsilun3  iscsigroup1          1    iSCSI
11：在host上面，重新启动iscsi service 发现LUN
  #service iscsi stop
  #service iscsi start
12: #fdisk -l
Disk /dev/sdd doesn't contain a valid partition table
[root@Fedora host4]# find /sys/devices/platform/host* -name "block*"
/sys/devices/platform/host4/session3/target4:0:0/4:0:0:1/block:sdd
/sys/devices/platform/host4/session3/target4:0:0/4:0:0:0/block:sdb
13: #mkfs.ext3 /dev/sdd
#mkdir /test
#mount /dev/sdd /test
注：1:在host 上面logout target
      #iscsiadm --mode node --targetname iqn.1986-03.com.ibm:sn.99932701 --portal 192.168.222.252:3260 --logout
2:[root@Fedora iscsi]# iscsiadm --mode node
   192.168.222.252:3260,1000 iqn.1986-03.com.ibm:sn.99932701
3:Display all information for the given node
   [root@Fedora iscsi]# iscsiadm --mode node --targetname iqn.1986-03.com.ibm:sn.99932701 --portal 192.168.222.252:3260
   node.name = iqn.1986-03.com.ibm:sn.99932701
   node.tpgt = 1000
   node.startup = automatic
   iface.hwaddress = default
   ...
   ...
