這期內(nèi)容當(dāng)中小編將會給大家?guī)碛嘘P(guān)如何進(jìn)行Netbackup code 98錯(cuò)誤的解析,文章內(nèi)容豐富且以專業(yè)的角度為大家分析和敘述,閱讀完這篇文章希望大家可以有所收獲。
前兩天nbu的幾個(gè)備份策略突然報(bào)錯(cuò),具體錯(cuò)誤代碼error requesting media (tpreq) (98), 錯(cuò)誤的具體信息是這樣的
2012/09/13 17:13:18 - Info bphdb(pid=6828388) Backup started
2012/09/13 17:13:18 - Info bphdb(pid=6840628) Backup started

2012/09/13 17:13:28 - current media -- complete, awaiting next media Any Reason: Media is in use, Media Server: S4PB02,

2012/09/13 17:13:30 - end writing
error requesting media (tpreq) (98)
從以上的報(bào)錯(cuò)信息提取兩行關(guān)鍵信息:
Error bptm(pid=5632) error requesting media, TpErrno = Robot operation failed
Warning bptm(pid=5632) media id 0044L4 load operation reported an error
該錯(cuò)誤提示機(jī)械臂操作失敗,0044L4磁帶載入作業(yè)報(bào)告了一個(gè)錯(cuò)誤。
首先查看當(dāng)前備份策略運(yùn)行狀態(tài)截圖
當(dāng)前有多個(gè)作業(yè)在跑,而工作的驅(qū)動器只有一個(gè)(帶黃圈的),正常情況下是兩個(gè)驅(qū)動器可以同時(shí)跑備份作業(yè).
首先使用scan命令檢查帶庫狀態(tài)
C:\Program Files\Veritas\Volmgr\bin>scan

發(fā)現(xiàn)狀態(tài)正常,然后使用tpconfig命令檢查驅(qū)動器狀態(tài)

發(fā)現(xiàn)驅(qū)動器狀態(tài)正常,那么為什么只有一個(gè)驅(qū)動器正常呢,難道卡帶了.試著在磁帶機(jī)中移動一盤磁帶看,發(fā)現(xiàn)可正常移入移出,應(yīng)該不是卡帶的問題.
現(xiàn)場檢查備份服務(wù)器和磁帶機(jī)后部的兩個(gè)驅(qū)動器的光纖卡和指示燈閃爍狀態(tài),發(fā)現(xiàn)光纖卡一切正常。有工程師建議說重啟帶庫,在這里我們要注意一個(gè)觀察一個(gè)問題,如果你發(fā)現(xiàn)有某塊光纖卡無信號燈閃爍,而此時(shí)有多個(gè)備份作業(yè)在跑那么鏈路是不正常的。需要重啟帶庫,帶庫重啟后再次掃描帶機(jī)有可能恢復(fù)正常?;蛘呷∠袀浞葑鳂I(yè),關(guān)閉磁帶機(jī)將那塊光纖卡無信號燈閃爍的驅(qū)動器拔出來重新插接進(jìn)去也可能正常了。)不過在這里光纖卡和指示燈狀態(tài)正常,鏈路也正常,那么在mounting磁帶時(shí)出錯(cuò),很有可能的就是磁帶的槽位變了,我們可以通過update volume configuration更新卷配置讓驅(qū)動臂找到正確的磁帶位置來解決這個(gè)問題。
我們來驗(yàn)證一下
更新完OK,故障解決。備份恢復(fù)正常,兩個(gè)驅(qū)動器都可以工作了.
