Client 端測試

1. 遠端測試 iscsi 硬碟是否存在？

   [root@kvm8 ~]# iscsiadm -m discovery -t sendtargets -p deyu.wang:3260
   Starting iscsid:                                           [  OK  ]
   192.168.122.1:3260,1 iqn.2012-05.wang.deyu:deyudisk
   

2. 遠端以 debug level 2 連上 iscsi

   [root@kvm8 ~]# iscsiadm -d2 -m node --login
   iscsiadm: Max file limits 1024 1024
   
   iscsiadm: default: Creating session 1/1
   Logging in to [iface: default, target: iqn.2012-05.wang.deyu:deyudisk, portal: 192.168.122.1,3260] (multiple)
   Login to [iface: default, target: iqn.2012-05.wang.deyu:deyudisk, portal: 192.168.122.1,3260] successful.
   

3. 連上後可以看到 /dev/sda，視為一顆新的硬諜使用。

   [root@kvm8 ~]# ll /dev/sda
   brw-rw----. 1 root disk 8, 0 Aug 10 01:17 /dev/sda
   

4. 遠端以 debug level 2 解開 iscsi

   [root@kvm8 ~]# iscsiadm -d2 -m node --logout
   iscsiadm: Max file limits 1024 1024
   
   Logging out of session [sid: 1, target: iqn.2012-05.wang.deyu:deyudisk, portal: 192.168.122.1,3260]
   Logout of [sid: 1, target: iqn.2012-05.wang.deyu:deyudisk, portal: 192.168.122.1,3260] successful.
   

5. 解開後 /dev/sda 不見了。

   [root@kvm8 ~]# ll /dev/sda
   ls: cannot access /dev/sda: No such file or directory
