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。

#!/usr/bin/env python3

# -*- coding: UTF-8 -*-

import glob
import operator
import os

if __name__ == "__main__":
    work_dir='/sys/class/fc_host/host*/port_state'

    for item in glob.glob(work_dir):
        f = open(item)
        for line in f:
            if line == 'Online
':
                wwn_item = item.replace("state", "name")
                fn = open(wwn_item)
                for wwn in fn:
                    print wwn,
                fn.close()
        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。

#!/usr/bin/env python3

# -*- coding: UTF-8 -*-

if __name__ == "__main__":
    f = open("112wwn")
    wwn_set=set()
    for line in f:
        wwn_set.add(line)
    f.close()
    print(wwn_set.__len__())

    f_host = open("172wwn")
    for wwn in f_host:
        if wwn in wwn_set:
            print('True')
        else:
            print('False')
    f_host.close()
