關於netbackup恢復出現media server is not active 問題

今天做一個恢復任務的時候，發現netbackup如下問題：

1、恢復操作遲遲沒有完成，檢視jobs

# bpdbjobs
JobID Type State Status Policy Schedule Client Dest Media Svr Active PID FATPipe
7129 Restore Active sol2 22233
7128 Image Delete Done 0 20130

該job7129一直為active

2、先檢視磁帶資訊，有空閒空間：

3、檢視詳細錯誤資訊為：

awaiting resource cbshp02-hcart3-robot-tld-0. Waiting for resources.

Reason: Tape media server is not active, Media server: sol1

Robot Type(Number): TLD(0), Media ID: N/A, Drive Name: N/A,

Volume Pool: unix, Storage Unit: cbshp02-hcart3-robot-tld-0, Drive Scan Host: N/A

4、檢視media server程式，該程式沒有running，原因不明。

# vmoprcmd -d

oprd returned abnormal status (96)
IPC Error: Daemon may not be running

# vmoprcmd -activate_host -h sol1

oprd returned abnormal status (96)
IPC Error: Daemon may not be running

5、參考相關文件：

6、依照此步驟處理：

Solution/Workaround:

1）、Ran nbrbutil -resetMediaServer (preferably nbrbutil -resetall)
2）、Restarted NetBackup daemons on media server - now tldd is running again
3）、vmoprcmd now works fine, and the volume pools "came back."

7、重啟MediaServer

# nbrbutil -resetall
# nbrbutil -resetMediaServer all

8、檢視MediaServer程式已經啟動：

# vmoprcmd -activate_host -h sol1
# vmoprcmd
