Written a python script to map device with specific host adapter...

!/bin/env python

import glob
import os,sys
import re

if sys.version_info < (2, 6) and sys.version_info < (2, 7):
print "This is not valid version"
sys.exit()

if sys.platform != "linux2":
print "This is not valid OS"
sys.exit()

os.chdir('/sys/block/')

dev_list = ['sd.','mmcblk']

def size(dev):
nr_sectors = open(dev+'/size').read().rstrip('\n')
sect_size = open(dev+'/queue/hw_sector_size').read().rstrip('\n')

# The sect_size is in bytes, so we convert it to GiB and then send it back
return (float(nr_sectors)*float(sect_size))/(1024.0*1024.0*1024.0)

def device_detail():
for dev in glob.glob('/sys/block/sd*'):
vendor_name = open(dev+'/device/vendor','r').read().rstrip('\n')
Read_link = os.readlink(dev).split('/')[4]
print ('Device {0}:: Size {1} GB :: Vendor {2}:: Controller {3}'.format(dev, size (dev), vendor_name, Read_link))

if name =='main':
device_detail()

首先检查 issue 中的 Python 脚本，以及它对 Linux /sys/block 条目、设备链接、扇区大小和供应商数据的使用。没有指定 repository 文件或测试，因此首先确定此脚本应放在哪里以及应如何运行。完成标准是提供一个可正常工作的、兼容 Linux 的设备映射示例，并明确其预期输出和验证方式。
