启动targetcli时遇到错误解决办法

当前环境[root@centos7-router ~]# more /etc/redhat-release CentOS Linux release 7.2.1511 (Core)安装targetcli工具包# yum install targetcli故障现象[root@centos7-router ~]# targetcliTraceback (most recent call last): File "/usr/bin/targetcli", line 24, in <module>  from targetcli import UIRoot  ### Author : Leshami File "/usr/lib/python2.7/site-packages/targetcli/__init__.py", line 18, in <module>  from .ui_root import UIRoot  ### Blog : http://blog.csdn.net/leshami File "/usr/lib/python2.7/site-packages/targetcli/ui_root.py", line 30, in <module>  from .ui_backstore import complete_path, UIBackstores File "/usr/lib/python2.7/site-packages/targetcli/ui_backstore.py", line 29, in <module>  from rtslib_fb import ALUATargetPortGroupImportError: cannot import name ALUATargetPortGroup

从上面的错误提示可知，python文件有问题。于是验证一下python是否已正确安装[root@centos7-router ~]# pythonPython 2.7.5 (default, Nov 20 2015, 02:00:19) [GCC 4.8.5 20150623 (Red Hat 4.8.5-4)] on linux2Type "help", "copyright", "credits" or "license" for more information.>>> python可以正常工作，继续google，原来是缺少python-rtslib这个包。[root@centos7-router ~]# yum install python-rtslib -y再次执行成功[root@centos7-router ~]# targetclitargetcli shell version 2.1.fb46Copyright 2011-2013 by Datera, Inc and others.For help on commands, type 'help'./> helpGENERALITIES============This is a shell in which you can create, delete and configureconfiguration objects.The available commands depend on the current path or targetpath you want to run a command in: different path havedifferent sets of available commands, i.e. a path pointing atan iscsi target will not have the same availaible commands as,say, a path pointing at a storage object.The prompt that starts each command line indicates yourcurrent path.
