本节给出Linux客户端挂载HBlock单机版的卷示例。
应用场景
Linux客户端需要连接HBlock单机版的卷。
需要连接的HBlock单机版的卷为lund1和lunf1，lund1有CHAP认证。
前置条件
对于需要连接HBlock单机版的客户端，已经按照客户端配置的前置条件成准备工作。
对于HBlock服务器端，已经成功创建卷lund1和lunf1。
操作步骤
HBlock服务器端
查询要连接的LUN及LUN对应iSCSI Target的详细信息。

发现lund1和lunf1的Target：
[root@client ~]# iscsiadm -m discovery -t st -p 192.168.0.32 192.168.0.32:3260,1 iqn.2012-08.cn.ctyunapi.oos:targetf.5 192.168.0.32:3260,1 iqn.2012-08.cn.ctyunapi.oos:targetd.4 192.168.0.32:3260,1 iqn.2012-08.cn.ctyunapi.oos:targetc.3登录iSCSI存储。
登录lund1的iSCSI存储，需要进行CHAP认证：
[root@client ~]# iscsiadm -m node -T iqn.2012-08.cn.ctyunapi.oos:targetd.4 -o update --name node.session.auth.authmethod --value=CHAP [root@client ~]# iscsiadm -m node -T iqn.2012-08.cn.ctyunapi.oos:targetd.4 -o update --name node.session.auth.username --value=testd [root@client ~]# iscsiadm -m node -T iqn.2012-08.cn.ctyunapi.oos:targetd.4 -o update --name node.session.auth.password --value=************* [root@client ~]# iscsiadm -m node -T iqn.2012-08.cn.ctyunapi.oos:targetd.4 -p 192.168.0.32:3260 -l Logging in to [iface: default, target: iqn.2012-08.cn.ctyunapi.oos:targetd.4, portal: 192.168.0.32,3260] (multiple) Login to [iface: default, target: iqn.2012-08.cn.ctyunapi.oos:targetd.4, portal: 192.168.0.32,3260] successful.登录lunf1的iSCSI存储
[root@client ~]# iscsiadm -m node -T iqn.2012-08.cn.ctyunapi.oos:targetf.5 -p 192.168.0.32:3260 -l Logging in to [iface: default, target: iqn.2012-08.cn.ctyunapi.oos:targetf.5, portal: 192.168.0.32,3260] (multiple) Login to [iface: default, target: iqn.2012-08.cn.ctyunapi.oos:targetf.5, portal: 192.168.0.32,3260] successful.
显示会话情况，查看当前iSCSI连接。
[root@client ~]# iscsiadm -m session tcp: [1] 192.168.0.32:3260,1 iqn.2012-08.cn.ctyunapi.oos:targetd.4 (non-flash) tcp: [2] 192.168.0.32:3260,1 iqn.2012-08.cn.ctyunapi.oos:targetf.5 (non-flash)查看iSCSI磁盘、磁盘对应的LUN（通过lsscsi -i可以查看LUN的wwid）。
[root@client ~]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 500G 0 disk sdb 8:16 0 600G 0 disk vda 253:0 0 40G 0 disk ├─vda1 253:1 0 4G 0 part └─vda2 253:2 0 36G 0 part / vdb 253:16 0 100G 0 disk └─vdb1 253:17 0 100G 0 part /mnt/storage01 vdc 253:32 0 100G 0 disk vdd 253:48 0 100G 0 disk [root@client ~]# lsscsi -i [2:0:0:0] disk CTYUN iSCSI LUN Device 1.00 /dev/sda 33000000068f2f320 [3:0:0:0] disk CTYUN iSCSI LUN Device 1.00 /dev/sdb 33000000030f798a5说明
可以看出/dev/sda对应HBlock卷lund1（卷WWID为33000000068f2f320），/dev/sdb对应HBlock卷lunf1（卷WWID为33000000030f798a5）。
