使用nbrbutil工具來處理requested media id is in use, cannot process request

首先我發現一個Media已經過期很久，但是并不會覆蓋重用

使用bpexpdate手動過期，失敗，讓他deassigned也不行

使用bpimmedia查看上面的image也沒有

我嘗試手動去過期，返回in use的信息。嘗試前面一篇帖子http://www.cnblogs.com/guilingyang/p/5585179.html的做法，也不能成功。最後找到了nbrbutil工具來解決

[root@nhpabk01 admincmd]# bpexpdate -m DD1083 -d 0  手動過期，失敗！
Media DD1083 is due to expire at 04/17/2016 19:54:14
Are you sure that the data on this media is not critical to
your business, and you are sure you want to delete DD1083 y/n (n)? y
requested media id is in use, cannot process request

[root@nhpabk01 admincmd]# bpexpdate -deassignempty -m DD1083   手動deassign，失敗
Search for empty media that meet the following criteria:
    Media id: DD1083

Continue? y/n (n)y
The following empty media will be deassigned:
    Host:nhpabk01    Media-id:DD1083
Are you SURE you want to continue y/n (n)?y
Could not deassign media-id DD1083, host nhpabk01: requested media id is in use, cannot process request (97)
Deassigned 0 out of 72 media-ids found.
requested media id is in use, cannot process request

[root@nhpabk01 admincmd]# bpimmedia -mediaid DD1083  查看image，沒有
no entity was found

最後使用nbrbutil工具來先把media從EMM裡面移除，再手動deassign就能成功了。具體如下：

[root@nhpabk01 admincmd]# nbrbutil -dump   列出MDS allocations in EMM里的media信息

MDS allocations in EMM:

特別注意上面的allocationKey和我們對應的mediaId
[root@nhpabk01 admincmd]# nbrbutil -releaseMDS 204833 通過這句命令來從EMM裡面釋放出media

這時候再執行nbrbutil –dump 該media不會出現在裡面EMM裡面了

接下來執行deassign作業

我首先根據下面的鏈接參考vmdelete來刪除media，但是提示該media是被assigned，無法delete

[root@nhpabk01 bin]# vmdelete -m DD1083
cannot delete assigned volume (92)   
[root@nhpabk01 bin]# cd -
/usr/openv/netbackup/bin/admincmd

我去執行deassigned作業，這里就能成功了。之前始終提示in use ，不能作業
[root@nhpabk01 admincmd]# bpexpdate -deassignempty -m DD1083
Search for empty media that meet the following criteria:
    Media id: DD1083

Continue? y/n (n)y
The following empty media will be deassigned:
    Host:nhpabk01    Media-id:DD1083
Are you SURE you want to continue y/n (n)?y
Deassigned media-id DD1083 on host nhpabk01
Deassigned 1 out of 73 media-ids found.

終於deassign 成功啦。這時候我去檢查該media的狀態，time assigned時間已經變為空了

[root@nhpabk01 admincmd]# nbemmcmd -listmedia -mediaid DD1083

通過這次對NBU的折騰，熟悉了一些NBU的命令。特別是/usr/openv/netbackup/bin/admincmd下面有很多管理命令

同時也注意到/usr/openv/volmgr/bin下面有一些命令可以操作。
