rhel7中，targetcli使用两位数的分区名字（比如sda10）而导致的问题：
[root@host1 ~]# fdisk -l /dev/sda
[root@host1 ~]# targetcli
targetcli shell version 2.1.fb41

IOError: [Errno 2] No such file or directory: '/sys/block/sda1/sda10/size'------------ls命令的报错！
[root@host1 ~]#
根据redhat.com文章：targetcli causes calltrace with the particular partition names which include 2 digits
建议：
Currently, there is no package to fix this issue. Red Hat is handling this issue in RHBZ#1312270
The workaround is to avoid creation iqn with the partition whose name contains two digits.
好吧，遇到bug了。不用sda10了，于是执行如下的命令：
[root@host1 ~]# targetcli
targetcli shell version 2.1.fb41
