available_media script incorrectly lists a volume's status as DBBACKUP

Question

Hello,
I would like to submit a problem I meet with one of my masters (Solaris 7.5.0.6)
in this domain there is one master (Solaris 7.5.0.6) and one media server (Windows 2K8 7.5.0.6)
My problem is that the tapes used by the media server are always shown with a DBBACKUP status in the available_media&nbsp; script output
After checking the available_media in detail first, it appears that if a tape is not found in bpmedialist -mlist -l output, available_media will display a DBBACKUP status for this particular tape
here is an example of the error with a specific tape B08121 I have
master:/root# available_media | grep B08121
	B08121&nbsp; HCART3&nbsp;&nbsp; TLD&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 94&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -&nbsp;&nbsp; DBBACKUP

	&nbsp;
I had a look at the technote TECH6059, but it is not relevant, the correction is already in place
Is there any workaround to get these tapes taken into account by the available_media script&nbsp; during bpmedialist -mlist -l on the master?

Just for your information, available_media is listed in the goodies directory and thus is not an officially supported command. You will not see it listed in the NetBackup Commands Guide.

Did you try to remove the media from emm?
Usage: vmdelete [-h &lt;EMM_server&gt; | &lt;volume_database_host&gt;]
	[-m &lt;media_id&gt; | -v &lt;volume_group&gt;]
	&nbsp;

Thank you for you reply
No I didn't, and it does not work
master:/root# vmdelete -h maser -m B08121
	cannot delete assigned volume (92)
This is normal, the tape contains data written by the media server that expire next 26th of December.
I can see the tape has active through the nbemmcmd, the EMM is aware then I guess
the problem is with the available_media script, it uses the command: bpmedialist -mlist -l
and the tapes used by the media server are not listed with this command.
I have updated available_media script to run below command instead and it works fine:
bpmedialist -mlist -l -h master -h mediaserver
master:/root# available_media | grep B08121
	B08121&nbsp; HCART3&nbsp;&nbsp; TLD&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 94&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 3&nbsp; 967744941&nbsp; ACTIVE/MPX
	&nbsp;
But this is just a workaround, and I would like to understand the root cause of the problem

Typically a volume will be flagged as dbbackup when available_media cannot get an accurate status.&nbsp; A default, so to speak.
This has been seen when the owning media server or Last Write Host cannot be contacted or had been decommissioned incorrectly.&nbsp; Worst-case scenario is mediadb corruption in EMM.
It might be worth your while to run the NBCC utility and create a Support case to have the results analyzed and potentially a NBCCR repair run.&nbsp; Check out:

looking into admin and bpdbm logs might give some hint
enable the admin and bpdbm logs with Verobse 5 and run the command&nbsp;
bpmedialist -ev B08121
then look into the logs for some hint
