查看服务器wwn是否在交换机侧

判断port_state是否为Online状态，是的话，读取出port_name，即为wwn。

 5 import glob
 6 import operator
 7 import os

 9 if __name__ == "__main__":
10     work_dir='/sys/class/fc_host/host*/port_state'
11 
12     for item in glob.glob(work_dir):
13         f = open(item)
14         for line in f:
15             if line == 'Online\n':
16                 wwn_item = item.replace("state", "name")
17                 fn = open(wwn_item)
18                 for wwn in fn:
19                     print wwn,
20                 fn.close()
21         f.close()

用集合来存放从交换机上获取的wwn信息，把从服务器上获取的wwn逐行读取，进行比对，看是否在集合内。

为True的话，说明可以从交换机上看到此台服务器。

 7     wwn_set=set()
 8     for line in f:
 9         wwn_set.add(line)
10     f.close()
11     print(wwn_set.__len__())

13     f_host = open("172wwn")
14     for wwn in f_host:
15         if wwn in wwn_set:
16             print('True')
17         else:
18             print('False')
19     f_host.close()
