1. 使用nbemmcmd列出media的詳細信息主要是Master Server信息

2.查看有沒有media ID在merge表里,如果有,不要再做操作,聯繫NBU處理;如果沒有,就繼續

[root@nhpabk01 admincmd]# nbemmcmd -listmedia -mergetable
NBEMMCMD, Version:6.5.6
The following number of records were found:0
Command completed successfully.

3.確定了沒有media在merge table里,就看看media ID是否有image

有的話就會列出IMAGE和FRAG行(這裡就是那些還沒有過期的media),沒有的話就不會輸出什麼(這裡就是那些已經過期或者沒有assigned的media)

[root@nhpabk01 admincmd]# bpimmedia -mediaid DD1084
IMAGE NHMIX01 8 NHMIX01_1465888536 NHCMO_FA_LUN_nhmix01_ORALOG_BL_H_D 4 Default-Application-Backup 2 11 1 1466147736 0 0
FRAG 1 1 256544 0 2 14 104 DD1084 nhpabk01 65536 5960601 1465614545 11 0 *NULL* 1466147736 0 11 1 *NULL*

[root@nhpabk01 admincmd]# bpimmedia -mediaid DD1083
no entity was found

 

4.只要media ID沒有出現在merge table,就能夠使用bptm命令來為受影響的media ID建立一個完整的media記錄(這裡說的是上面master Server不存在的情況,不存在主要是一些,通過該命令來讓media ID的master Server呈現出來),只要有了完整的信息,Media ID就能夠使之expired和unsigned.

bptm命令需要知道Media ID,density,volumn pool number三個參數

[root@nhpabk01 admincmd]# bptm -makedbentry -m DD1083 -den hcart2 -poolnum 4
bptm: media db entry for DD1083 already exists, aborting
Error - media manager - system error occurred
我這裡是該media ID已經存在db entry里了

 

5. 接下來就可以用bpexpdate來過期media

bpexpdate –m DD1083  –d 0
