客户一套IBM TS3200带库更换driver1后出现数据库备份不成功的问题，查看数据库备份日志如下：SQL2033N An error occurred while accessing TSM during the processing of a
database utility. TSM reason code: "1".
TSM服务端报错:ANR8779E Unable to open drive /dev/rmt0，error number=79；通过此报错日志进入aix查看rmt0，查看rmt0信息如下
rmt0 U78AA.001.WZSJZUD-P1-C5-T1-W2002000E11159139-L0 IBM 3580 Ultrium Tape Drive (FCP)
Manufacturer................IBM
Machine Type and Model......ULT3580-TD4
Serial Number...............1310297528
Device Specific.(FW)........C7QH
Serial Number还是之前坏的那个drive的SN，不知道是不是这个原因导致的备份失败，有大佬帮忙解答下吗？
