DFM error: could not get platform limits

[jmberoud]

Hello,

We have some strange errors while snapcreator is monitoring the snpavault update via dfm:

<error-message>snapcreator_asapt401: Could not get platform limits for volume host_id 9953 with phys host_id 9953 while fetching information for volume nabackup02:/sv_asapt401_oradb (10984) from database.</error-message>

<error-message>snapcreator_asapt401: Could not get platform limits while fetching current information for volume nabackup02:/sv_asapt401_oradb (10984).</error-message>

<error-message>snapcreator_asapt401: Could not get live vol usage from filer for nabackup02:/sv_asapt401_oradb.  Resize not possible.</error-message>

The job was working without errors when snapvaulting to a FAS2040 (ONTAP 8.0.3Px). Now we get these errors when snapvaulting to a FAS2220 (ONTAP 8.1.1)

Question: is it a problem with snapcreator, dfm, dfm plugin, hw platform?

Best regards,

Jean-Marc

Jean-Marc,

Its a DFM issue. I suspect the reason you're getting this error is that your DFM server does not have resouce limits defined for that particular combination of storage system and ONTAP (FAS2220 + ONTAP 8.1.1).  This tells me you're running a version older than OnCommand 5.1. You just need to manually define the resource limits for this and this error will go away.

Here is a link to a discussion on how to define a resource limit for a given controller and ONTAP version

https://communities.netapp.com/message/69347

Here is an exmaple.  NOTE:  Check to see what the actual maximum volume deduplication size is for a FAS2220 in ONTAP 8.1.1 before running this command. These are just examples of how to define a resource limit.

# dfpm reslimit create 8.1.1 FAS2220

Created new resource limit (309).

# dfpm reslimit set 309 maxFlexVols=500

# dfpm reslimit set 309 maxDedupeSizeInGB=16384

Run your SnapCreator job again and these messages should go away.

If your FAS2220 is an HA pair, use the "-c" flag when you create the reslimit.  For example:

# dfpm reslimit create -c 8.1.1 FAS2220

Hello Reid,

Thanks a lot for your answer. It works now :-). I'm suprised that it is not defines in the latest DFM 5.1.

Jean-Marc,

If you can, edit this post and change the title to "DFM error: could not get platform limits".  This will help others working with SnapCreator to find this post and resolve their issue.

Thanks.
