bpduplicate failing with Error nbjm (pid=8918) NBU status: 800, EMM status: Media server mismatch

Hi,

      I am trying to duplicate images to two different destinations simultaneously but it is failing with the error below, shown in the Activity Monitor.

Error nbjm (pid=8918) NBU status: 800, EMM status: Media server mismatch

Can't seem to find where to look for what this actually means.

Command I'm using is

/usr/openv/netbackup/bin/admincmd/bpduplicate -fail_on_error 0,1 -number_copies 2 -v -rl 11,11 -cn 3
-dstunit appl01_dedupe_disk,appl02_dedupe_disk -Bidfile /tmp/dupe_images_RUN1 -L /tmp/dupe_images_RUN1.log

Log file says

11:56:36 Duplicate started 05/17/2019 11:56:36
11:56:36 Activity monitor job id = 16799635
11:56:36 Copy 1 activity monitor job id = 16799636
11:56:36 Copy 2 activity monitor job id = 16799637
11:56:36 INF - Cannot obtain resources for this job : error [800]

We used to do this when we were tape based, but this is all appliance / dedupe pool based now.

The images will duplicate to the destinations separately so there are no credential issues etc.

Any help appreciated as its got me stumped at the moment.
