一.openfiler iSCSI配置

1.启动iSCSI target server服务。在Services列表下。

2.设置访问列表。在System---Network Access Configuration下设置。

3.创建卷设备

二.ISCSI客户端配置

1.安装open-iscsi

# apt-get install open-iscsi

2.发现iscsi-target

# iscsiadm -m discovery -t sendtargets -p 192.168.41.111

192.168.41.111:3260,1 iqn.2006-01.com.openfiler:tsn.1a8f5a5d6ffb

3.挂载

# iscsiadm -m node -T iqn.2006-01.com.openfiler:tsn.1a8f5a5d6ffb -p 192.168.41.111 -l -d 10

4.设置自动登录到iscsi-target

# iscsiadm -m node -T iqn.2006-01.com.openfiler:tsn.1a8f5a5d6ffb -p 192.168.41.111 --op update -n node.startup -v automatic
