问题分析：
原因是带库报告的条码位数从8改成6了，在带库管理界面上可以检查：
参考 https://www.ibm.com/support/knowledgecenter/en/STCMML8/com.ibm.storage.ts3500.doc/opg_3584_a69oop6volser.html ：
Procedure
- From the Work Items navigation pane, select Library —> Logical Libraries. The Manage Logical Libraries screen displays.
- Select the logical library you want to change to 6-character VOLSER reporting.
- In the Select Action drop-down list, select Modify Volser Reporting.Then, select GO.
- Under Volser Reporting select either 8 (default) or 6 then click APPLY and CLOSE. The library displays the message Logical Library Volser reporting change is complete.
