"A pending request has been generated for this resource request"

Created: 23 Apr 2013 | 9 comments

Hi,

I know this issue has been discussed in forums earlier and I have tried all the mentioned steps but still I continue to get the same error.

Environment..

NBU 7.5.0.3, windows 2k3 master (no devices attached)

NBU 7.5.0.3, RHEL AS5

Media with issue is a virtual media. Just to ensure that there is nothing wrong with device database, I changed it to Standalone and ran inventory. It continues to give the same issue.

nbrbutil -listActiveMediaJobs lists the exact job for media.

I have tried to deny, reassign and resubmit the request but eventually it continues to show the pending request.

Please suggest..

If NetBackup cannot service a media-specific mount request automatically, it changes the request or action to a pending state.Is this with all the media or with a specific media ? Did you check bptm logs ? Also check windows event logs for any error in applictaion logs when you assign the drive to pending request. You can try vmoprcmd -assign -drive_index mount_request_id and then check the logs.

Hi Deeps,

 

I havnt gone through any of the logs as of now.. I tried vmoprcmd to mount the drive and the stands still with this

I am not sure from where its picking

When the media has always been handled/owned by this specific media server.

Hi Marianne,

 

Here are the outputs you had mentioned.. I gathered the first one while I was trying to resubmit the request for allocation.

This media is part of a media set that is needed for a duplication job that seems to be in progess:

Allocation              DUP-READ

Not sure what will happen to the duplication job if you clear the Mds allocations for this tape:

MdsAllocation: allocationKey=77922703

MdsAllocation: allocationKey=77922704

Depending on how important this restore is, you may want to consider it...

Media is not needed for restore... its just this duplication which has been hanging around for a while.

In the detailed status the status is

24/04/2013 2:00:02 PM - awaiting resource IBM.ULTRIUM-TD2.054:LameMove_VTL_DR:L01227 A pending request has been generated for this resource request.

  Volume Group: 000_00002_TLD, Action Acs: N/A, Action Lsm: N/A
 

Media and drive are allocated to this job and are available. Issue is this media should be mounted, read and duplication should be processed as normal but it creates a pending request.

It has been doing this for last 21 hours.

Seems NBU believes that the media is needed for duplication...

Please clear the mds allocations

Hi Marianne,

I did not make myself clear, my bad  ... the issue is

I have this duplication in queue which requests this media. The media gets allocated to job(nbrbutil shows), but netbackup fails to mount the media stating the above error.

I tried to see if there are any other jobs holding on to this media but there is nothing. Other aspect checked was if there is any potential issue with the ownership of this media(as detailed job status complains about it).. none found as nbemmcmd -listmedia output is all clean.

I tried to reinventory the robot to ensure that NBU is updated with right slot info..

But still when the duplication job mounts the media, a pending request shows up.. I am not sure how to clear this pending request.

Marianne's picture

Still seems that there is some orphaned allocation in NBU resource broker.

I still feel it may be a good idea to release all allocations - this may kill the current queued duplication job, but it should be easy enough to restart.

You can first of all try to reset all allocations for this media server:

nbrbutil -resetMediaServer <name>

If that does not work, try to reset all allocations:

nbrbutil -resetAll
