TSM重新启动磁带库和备份服务器后，备份不成功。或者是SAN网络出现调整做了新的配置后，导致备份不成功

delete path tsmserver drive1 srctype&＃61;server desttype&＃61;drive library&＃61;ts3100lib

delete path tsmserver drive2 srctype&＃61;server desttype&＃61;drive library&＃61;ts3100lib

删除旧磁带机设备名

delete drive ts3100lib drive1

delete drive ts3100lib drive2

如果删除旧磁带机设备名的时候报错&＃xff0c;先q path查看 如果On-Line是YES&＃xff0c;先运行以下内容然后再删除旧磁带机设备名

delete path  P570A_AGENT  drive1 srctype&＃61;server desttype&＃61;drive library&＃61;ts3100lib

delete path  P570A_AGENT  drive2 srctype&＃61;server desttype&＃61;drive library&＃61;ts3100lib

删除旧磁带库路径

delete path tsmserver ts3100lib srctype&＃61;server desttype&＃61;library

删除旧磁带库设备名

delete library ts3100lib

3.2 重新配置设备

   重新定义磁带库设备和路径: (顺序和删除相反)

在TSM  management console 查看 tsm device driver 有磁带库和磁带设备:  lb1.1.0.3 和mt0.0.0.3 , mt1.0.0.3 &＃xff08;接下来的定义中&＃xff0c;要定义成一致&＃xff09;

define library ts3100lib libtype&＃61;scsi shared&＃61;yes

define path tsmserver ts3100lib srctype&＃61;server desttype&＃61;library device&＃61;lb1.1.0.3

   重新定义磁带机设备

define drive ts3100lib drive1

define path tsmserver drive1 srctype&＃61;server desttype&＃61;drive library&＃61;ts3100lib device&＃61;mt0.0.0.3

define drive ts3100lib drive2

define path tsmserver drive2 srctype&＃61;server desttype&＃61;drive library&＃61;ts3100lib device&＃61;mt1.0.0.3

4 检查磁带库卷和检入卷

q libvol

checkin libvolume ts3100lib search&＃61;yes checklabel&＃61;barcode status&＃61;private

&＃xff08;最后一步&＃xff0c;如果q libvol显示出不来&＃xff0c;就先运行下面这条&＃xff09;

 &＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;

一、描述&＃xff1a;
对于windows平台&＃xff0c;经常出现在机器重启后&＃xff0c;带库设备名称变化&＃xff0c;导致tsm中配置不匹配&＃xff0c;备份报错等问题

比如 原来是 mt0.0.0.3
重启后 变成了 mt1.0.1.3

二、原因&＃xff1a;
tsm 对于设备命令有不同的方式&＃xff0c;在aix平台下&＃xff0c;比较智能
但在windows 平台下&＃xff0c; tape driver 特有功能是可以 在重启后&＃xff0c;自动变化设备名称的。&＃xff08;具体原因我不知道&＃xff0c;别问我为什么哦&＃xff09;

三、解决方法&＃xff1a;
在注册表里面创建一个key
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\ibmtp2k3\PersistentNaming 

赋值 DWORD value&＃61;1

重启机器

在HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\ibmtp2k3 子键下查看 最新的wwn 序号

&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;&＃61;

问题&＃xff1a;由于SAN网络割接&＃xff0c;导致主机rmt设备名称导致变化

解决&＃xff1a;将变化的设备名用下面命令更新&＃xff0c;注意新的rmt设备名(注意红色字体的对应关系)要与DRIVE的WWN号相对应

 注意DRIVE3对应rmt2

          DRIVE4对应rmt0

         由红色部分的WWN号与序列号可以找出对应关系&＃xff08;如果对应关系不对&＃xff0c;发起备份时&＃xff0c;命令query path显示的路径会offine&＃xff09;

UPDATE PATH STA_MISAPP1 DRIVE3 SRCTYPE&＃61;SERVER DESTTYPE&＃61;DRIVE LIBRARY&＃61;3584LIB DEVICE&＃61;/dev/rmt2

 UPDATE PATH STA_MISAPP1 DRIVE4 SRCTYPE&＃61;SERVER DESTTYPE&＃61;DRIVE LIBRARY&＃61;3584LIB DEVICE&＃61;/dev/rmt0
