NB Catalog recovery keeps failing on NBDB recovery

    Quick update...

    I noticed errors in media server bptm:

    10:28:18.458 [13561] <16> emmlib_initializeEx: (-) Exception! CORBA::NO_PERMISSION
    10:28:18.459 [13561] <16> bptm: (-) Translating EMM_ERROR_Authorization_Denied(3000007) to 118 in the NetBackup context
    10:28:18.459 [13561] <16> bptm: error (118) initializing EMM interface.
    10:28:18.459 [13561] <16> main: (-) Translating ERROR UNDEFINED(118) to 196 in the Media context

    When I googled that it seemed to indicate a dns issue, which there is: on the master, the reverse IP lookup for the media server fails. It did not occur to check that since I was able to add the media server, and recover db images. So I figured, let me duplicate the NBDB backup image to local disk on the media server, and recover from that copy. bpduplicate failed with error code 47. Seems some process keeps removing the media server. Added it back to the Masters additional server and media server config, and bpduplicate ran, and NBDB recovery from the disk copy worked. I got DB validation errors, but I can at least do restores now.

That was a typo...Windows 2012 master, NB version is 7.7.3. It only used for old restores. Looks like the images part of the catalog recovery worked, but I guess its failing on the last part, the NBDB recovery.

Recover log on master shows:

hi

the source and target server name are identical, right?

etc/hosts is pointing to correct server - or you do use dns - which I doubt as two same hostnames cant appear on AD...

    Same host name. I did a manual deinstall of the corrupted 7.7.3, and just re-installed on same host.

    I had some challenges due to the media server not having been the original catalog backup media server, but I got around that.
