SQL Query for aggregate / disk reporting issue

christop — Thu, 05 Jun 2025 06:01:10 GMT

Working with a customer to build some SQL queries for reporting against a DFM 4.0.2 instance.

We are doing query joins for disk, plex, raid group, and aggregate to tie disks back to their aggregates, however about 80 of 300 aggregates not reporting anything due to a break in the chain showing NULL values for plex, RG, or aggr.

Here's the query:

select distinct a.aggrid

,o.objName

,a.aggrstoragesystemid

,d.disktype

,p.plexaggrid

,r.rgplexid

,d.diskrgid

from aggregateview a

left join objectview o on a.aggrid = o.objid

left join plexview p on a.aggrid = p.plexaggrid

left join raidgroupview r on p.plexid = r.rgplexid

left join diskview d on r.rgid = d.diskrgid

Could this be a permissions issue between the DFM host and the host login credentials for each storage system?

Any guidance would be welcome.

Thanks,

Chris

Hi Chris,

DFM monitors disk using api and strorage system credentials must be set in dfm in-order for it to gather that data.

Can you run dfm cli and see if the disk reports give you this data ?

Also if you can give me the template ( column names with example ) of what you are looking for I can help you get this

Thanks Adai. We cleaned up the credentials and that seems to have resolved it.

Hi Adai,

One more question. The customer wants to report on spare disks and "unowned"disks. What field or fields would help us identify spares and unowned disks?

Thanks,

Chris

Hi Chris,

The diskRole field gives the details of the disk role, like data, parity, spare etc. Unfortunately, an unowned disk is never discovered by OCUM or for that matter system manager as well. Only owned disk is reported in case of OCUM and SM as well and aggr can only be created using owned disk.
