【Teradata】DSA+NBU备份1148错误

1.问题描述

备份过程中在viewpoint中查看备份失败代码为1148，具体描述如下：

Communication通信[kəˌmjuːnɪˈkeɪʃn] failed失败 [feɪld] detected发现[dɪˈtektɪd] initiated初始化 [ɪˈnɪʃieɪtɪd]  retrieved检索 [rɪˈtriːvd]

1148, DSA DSMAIN-BARNC Communication Exception:1001:(cedw-edwbak2) BSASendDat a failed
retcode=3: "System detected error, operation aborted."
BSAGetLastError: "Check logs in /usr/openv/netbackup/logs for NetBackup errors "
ServerError -1: "Server Status: Communication with the server has not been initiated or the server status has not been retrieved from the server."

2.原因分析

初步判断edwbak2机器上的NBU的客户端，连接Server端时失败。经NBU确认，属于磁带不足导致。
