本文记录了一次NetBackup备份过程中遇到的问题及解决过程。备份策略出现错误提示，通过检查进程状态、重启相关服务等步骤最终定位到nbu进程异常导致的问题，并通过执行特定脚本解决了该问题。

今天有个备份策略出问题，报错内容是这样的：

04/24/2008 00:03:00 - requesting resource bfepdb-hcart2
04/24/2008 00:03:00 - requesting resource bfbkup.NBU_CLIENT.MAXJOBS.bfepdb
04/24/2008 00:03:00 - requesting resource bfbkup.NBU_POLICY.MAXJOBS.bfep_db
04/24/2008 00:03:00 - awaiting resource bfepdb-hcart2. Waiting for resources.
          Reason: Tape media server is not active, Media server: erpdb,
          Robot Type(Number): TLD(0), Media ID: N/A, Drive Name: N/A,
          Volume Pool: DB_ep_full, Storage Unit: bfepdb-hcart2, Drive Scan Host: N/A
client backup was not attempted because backup window closed (196)

在master server打开控制台,deivce--host,发现的status是“active for disk”。由于这个media server上面连接的是磁带库。正常应该是“active for type and disk”于是在这台机器上执行tpconfig –d,一直没有反馈信息。

1.通过bpps查看进程：

NB Processes
------------
    root 11379     1 0 15:24:23 ?         0:00 /usr/openv/netbackup/bin/bpcompatd
    root 11384     1 0 15:24:28 ?         0:00 /usr/openv/netbackup/bin/nbsl
    root 11356     1 0 15:24:17 ?         0:00 /usr/openv/netbackup/bin/nbnos
    root 11391     1 0 15:24:29 ?         0:00 /usr/openv/netbackup/bin/nbsvcmon

MM Processes

    root 11494 11364 0 15:30:37 ?         0:00 tldd
    root 11364     1 0 15:24:20 ?         0:00 /usr/openv/volmgr/bin/ltid
    root 11497 11364 0 15:30:39 ?         0:00 avrd
    root 11480     1 0 15:30:34 ?         0:00 vmd

没有发现异常情况。

2.在master server上执行:

vmdareq -a

发现没有bfepdb这个media server的信息，决定重启nbu进程。netbackup stop后bpps -a

设备也没有什么异常情况。

4.接着netbackup start，再手工启动策略问题依然存在。

5.再次netbackup stop后执行bp.kill_all，彻底杀掉nbu进程，再netbackup start启动nbu，vmdareq -a一切正常。

# netbackup start

NetBackup Database Server started.
NetBackup Notification Service started.
NetBackup Enterprise Media Manager started.
NetBackup Resource Broker started.
Media Manager daemons started.
NetBackup request daemon started.
NetBackup compatibility daemon started.
NetBackup Job Manager started.
NetBackup Policy Execution Manager started.
NetBackup Service Layer started.
NetBackup is not configured for clustering.
NetBackup Service Monitor started.

# vmdareq -a

Drive2 - AVAILABLE
     bfbkup UP
     erpdb UP
Drive3 - AVAILABLE
     bfbkup UP
     erpdb UP
HPUltrium2-SCSI0 - AVAILABLE
     bfbkup UP
     erpdb UP
HPUltrium2-SCSI1 - AVAILABLE
     bfbkup UP
     erpdb UP

6.结论

出现这种问题，可能是由nbu进程的异常造成的。但是正常的重启可能仍然不能解决问题，这时候需要执行bp.kill_all脚本来停止nbu的后台驻留程序。
