Iscsi常用命令（我通过openfiler实现iscsi存储）

# iscsiadm -m discovery -t st -p IP:port     //发现iSCSI存储

# iscsiadm -m node -o delete -T TARGET -p IP:port    //删除iSCSI发现记录

# iscsiadm -m node          //查看iSCSI发现记录

# iscsiadm -m session     //查看会话情况

# iscsiadm -m node -T TARGET -p IP:port -l       //登录iSCSI存储
# iscsiadm -m node -T TARGET -p IP:port -u      //登出iSCSI存储

vim /etc/iscsi/initiatorname.iscsi    //添加客户端认证

InitiatorName=iqn.2018-12.com.oven:client     //名称与服务端acl设置的名称一致

systemctl restart iscsid    //更新IQN
iscsiadm -m node -T iqn.2018-12.com.oven:master -p 192.168.4.10 -l   //更新IQN后登录成功

 

[root@rhel1 ~]# fdisk /dev/sde      --分区

[root@rhel1 ~]# udevadm  test /sys/block/sde ----查看信息

 

配置udev来固定iscsi磁盘分区

[root@rhel1 ~]# vi /etc/udev/rules.d/99-openiscsi.rules     ---->redhat7

ASM配置安装

[root@rhel1 ~]# yum install kmod-oracleasm.x86_64

[root@rhel1 ~]# rpm -ivh /soft/oracleasmlib-2.0.12-1.el7.x86_64.rpm

[root@rhel1 ~]# rpm -ivh /soft/oracleasm-support-2.1.11-2.el7.x86_64.
