LSI HBA卡下硬盘物理槽位和OS盘符对应脚本

有个大客户需要一个脚本可以打印出当前服务器上在位的硬盘OS下的硬盘盘符和服务器物理硬盘槽位号的对应关系，由于涉及HBA卡，所以无法实现一个通用的，只能是适用于这个配置的。经过验证在掉一个盘的情况下，其它硬盘的盘符不会发生漂移，掉盘多个的情况下会发生漂移，由于客户的使用场景一般掉盘一个就会预警了，所以这个需求还是有实现价值的。由于服务器上的是LSI的HBA卡，经过验证，盘符分配没有规律可循，只能记下满配时的盘符关系，用来检索输出。
思路就是先生成一个正确的物理槽位-盘符-阵列卡下槽位的对应关系，然后用阵列卡的工具去获取当前阵列卡下在位的硬盘槽位号，根据槽位号去获取正确的物理槽位，然后序列号和model根据盘符用smartctl命令获取
最终实现效果如下
