All log directories should be created under /usr/openv/netbackup/logs with 777 permissions.
/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//bdump.

请在这台 client上,调整bmrsavecfg 的log level
Install_path\netbackup\bin\vxlogcfg –a –p 51216 –o 121 –s DebugLevel=6 –s DiagnosticLevel=6

运行命令,如果命令报错,将报错信息也发给我。

上面的命令返回提示符后,立刻运行命令搜集 log
Install_path\netbackup\bin\vxlogview –p 51216 –o 121 –t 00:10:00 –d all > c:\121.txt

搜集该主机上以下文件,

将以上 /tmp/下的log 和命令输出文件发给我。
将后两个排队作业的 detailed status信息复制粘贴到txt文本文件发给我。
并且告诉我您同时发起的 policy的名字。


///////////////////

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
/usr/openv/netbackup/bin/vxlogview -p 51216 -o 111 -t 00:10:00 -d all > /tmp/111.txt

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
