Thanks mph999,
The "CONSISTENCY_ERROR Oper_20_4" message desapeared with the following commands (21 old medias removed):
nbemmcmd -listmedia -mergetable
nbemmcmd -deletemedia -mediaid [XXXXXX] -originhost [masterServerName]
nbemmcmd -deletemerge -assignedhost NONE -mediaid [XXXXXX]
But, like you had supposed, inconsistency keeps. Now, I believe that there are something wrong with my valid medias. I attached the new result of nbcc command, so if possible, take a look to help me in this case.
Thanks about nbcc information, otherwise, like you said, it's better to run it to prevent some dataloss, am I right?
Tks,
Marcio Oliveira
