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
