Protection Manager can't manage SV Relationship within same filer

JGPSHNTAP

So, i'm testing something out, and i thought i read somewhere that PM can't manage SV relationship within same filer.  Even though relationship is in different aggregate.    I set one up, and did dfpm relationship list after dfm host discover and didn't see it in external relationship. 

This is just a lab scenerio, but i'm curious.

Please advise and if you have linkage that would be great.

thanks

Older versions of UM/DFM prevented creating relationships to the same controller due to an ONTAP limitation.  Once that limitation was removed UM still only allowed relationships to different aggregates on the same controller.  However, this changed in UM 5.2 using the dpAllowSameAggrRels option.

See this public report for details:

Kevin,

Hmm.. I was aware of the same aggr limitation, so I set this up in the different aggregates, aggr1, aggr0, but still no luck.    I'm running 5.2 in the lab. 

I also don't see that option available on our UM 5.2 server.

From the PR:

....using the hidden option "dpAllowSameAggrRels".

For example:

# dfm option set dpAllowSameAggrRels=1

Changed allow a relationship within a single aggregate to 1.

Hidden options are not visible until set/changed.

Thanks,

Kevin,

Ok, I see that, but to my above point, i'm going to different aggregates on same controller.  Do I still need that option

kryan

No, that option is for using the same aggr.

How long did you wait after refreshing the monitors?

Are there any error regarding that relationship int eh svmon.log?

Kevin

JGPSHNTAP

Hmm.. Kevin something is off.. I see we are on the same page now with the aggrs.

I forget to check the sv log - here is the error - Invalid primary path /vol/sv_test_m

Now that's bull.. what's wrong with that path?

kryan

Protection Manager has never been able to vault a volume - you will need the relationship to be in the following format for PM to use it:

/vol/sv_test_m/-

OR

/vol/sv_test_m/qtree1

You can read details in this PR:

DataFabric Backup Manager and Protection Manager do not support volume-to-qtree SnapVault

Kevin,

Yup, that did it.  Interesting read on the PR.
