available_media script incorrectly lists a volume's status as DBBACKUP

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  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  HCART3   TLD      0       94      -       -          -   DBBACKUP

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  during bpmedialist -mlist -l on the master?

Just for your information,

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 <EMM_server> | <volume_database_host>]
[-m <media_id> | -v <volume_group>]
 

 

Thank you for you reply No I

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  HCART3   TLD      0       94      -       3  967744941  ACTIVE/MPX
 

But this is just a workaround, and I would like to understand the root cause of the problem

Typically a volume will be

Typically a volume will be flagged as dbbackup when available_media cannot get an accurate status.  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.  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.  Check out:

enable the admin and bpdbm logs with Verobse 5 and run the command 

bpmedialist -ev B08121

then look into the logs for some hint

Hi Revaroo, I agree

Hi Revaroo, I agree availble_media script is just an addon tool (very useful by the way)

My concern was more with the bpmedialist command in general (why the -h is mandatory in certain case)

I ran a NBCC but it gave me no error, and nothing wrong found in the admin nor bpdbm logs

This is not a blocking point I have updated the availble_media script and it works fine for me in this case

Thank you all for your support
