/usr/openv/netbackup/logs/bphdb
/usr/openv/netbackup/logs/bpcd
/usr/openv/netbackup/logs/dbclient
2. Attempt the backup or restore operation
3. Gather the appropriate debug information from the backup client
a. The content of all the error logs at /usr/openv/netbackup/logs
b. The backup script and the output of the backup script with exact error messages
c. /usr/openv/netbackup/bp.conf and bp.conf at home directory of oracle OS user if exists.
d. The oracle database version information
sqlplus “ / as sysdba”
SQL> select * from v$version;
SQL> select * from v$instance;
e. In case of oracle report critical errors (e.g. ORA-0600) or backup hang for a long time without response, we also need to collect the oracle alert log at $ORACLE_BASE/admin/

如果我遇到 catalog备份失败的问题,我会按照以下流程操作
1. 向用户确认,之前 catalog备份是否都成功。如果成功,需要检查这次失败的原因,或者重启一下 NBU,备份 catalog,看结果;如果新配置的,需要检查 catalog policy的配置。
2. 确认这次备份 catalog起了几个作业,应该是4个 job。让用户把 catalog失败job 的detailed status发给我们。
3. 根据status信息初步判断问题所在,如这个 case中是811
先检查一下
Install_path\netbackup\bin\admincmd\nbrbutil -dump > c:\nbrbdump.txt
Install_path\netbackup\bin\admincmd\bppllist -allpolicies -L > c:\pol.txt
Install_path\netbackup\bin\admincmd\bpstulist -L > c:\stu.txt

Install_path\volmgr\bin\vmoprcmd > c:\vmoprcmd.txt
Install_path\volmgr\bin\tpclean -L > c:\tpclean.txt
搜集相关 log
打开NBU Console界面, Host Properties > Master Servers, 右键master server ,点击Properties,选择 Logging, 勾选Enable robust logging ,设置Global Logging Level为 5。
创建log 目录
Install_path\netbackup\logs\bptm
Install_path\netbackup\logs\bpbrm
重启NBU的服务,重新发起 NBU的 catalog备份,如果失败,将bptm和 bpbrm下的log 发给我们。
仍然失败, bptm和bpbrm 还是有811报错
需要搜集 unified log
/usr/openv/netbackup/bin/vxlogcfg -a -p 51216 -o 111 -s DebugLevel=6 -s DiagnosticLevel=6
调整nbemm,nbrb,nbjm的 log level
/usr/openv/netbackup/bin/vxlogcfg -a -p 51216 -o 111 -s DebugLevel=6 -s DiagnosticLevel=6
/usr/openv/netbackup/bin/vxlogcfg -a -p 51216 -o 117 -s DebugLevel=6 -s DiagnosticLevel=6
/usr/openv/netbackup/bin/vxlogcfg -a -p 51216 -o 118 -s DebugLevel=6 -s DiagnosticLevel=6
重新发起备份,失败后
搜集log

将清洗带删除掉,重新按照以下配置。
1.删除清洗带
2.重新做robot inventory ,设置清洗带的类型,放入 NONE pool,清洗带类型和磁带机的类型一样,如磁带机是 hcart2的,那清洗带是1/2’’ cleaning tape 2 类型
3.双击清洗带,设置清洗次数, Number of cleanings remaining > new account ,输入一个数字,如30
4.检查清洗带剩余清洗次数 ,使用命令 install_path\volmgr\bin\vmquery -m media_id_cleaning_tape 检查输出想的 cleanings left 参数

1.将当前其他的备份作业取消掉,可以执行以下命令 ,
/usr/openv/netbackup/bin/admincmd/nbrbutil -resetAll
/usr/openv/netbackup/bin/admincmd/nbrbutil -dump (通过这条命令确认没有资源信息的输出)
2.删除master server 上的磁带库设备,
/usr/openv/netbackup/bin/admincmd/nbemmcmd -deletealldevices -machinename SZBK52SVC -machinetype media
通过命令检查确认,没有设备输出。
/usr/openv/volmgr/bin/tpconfig -d
3.停NBU 的服务
/usr/openv/netbackup/bin/goodies/netbackup stop
/usr/openv/netbackup/bin/bpps -x (确认除了pbx_exchange进程,没有 NB和 MM的进程了)
