Looking for a report showing volumes/qtrees/quotas under and over committed

Hi,

(NOTE: My context for this inquiry is "Clustered ONTAP" but I wonder if a 7-mode report exists ... and OCUM 5.1 on Linux)

My customer uses qtrees within volumes extensively and sets qtree-quotas to divide the space up inside volumes. They do not always have the qtree-quotas set correctly and they know they have some volumes that are over committed (example: a 100GB volume with 2 60GB qtree-quotas -> or over committed at 120%) and some under committed (example: 100GB volume with 2 40GB qtree-quotas -> or under committed at 80% with 20GB unaccessible/wasted).

We found a "good" report to detect and report these situations called volumes-quota-committed (sample below -- run from CLI because I don't see it in the GUI Reports):

Object ID Volume Aggregate Storage Server Used Committed Committed (%) Total/Max Size

--------- ----------------- --------- --------------- ------------ ------------ ------------- --------------

3910 proj10010c n04_sata atxvs01 219495404 734003200 139.0 527958016

3943 proj6014c n03_sas atxvs01 1037216172 2097152000 111.1 1887436800

3941 proj6013c n02_sas atxvs01 729033860 2097152000 111.1 1887436800

3464 proj6008c n02_sata atxvs01 564352 104857600 105.3 99614720

3470 proj10009c n02_sata atxvs01 11196144 209715200 105.3 199229440

The "ideal" report would be like the above but after each volume, would list the qtrees and their quotas and usage so the decision can be made whether it makes more sense to change the size the volume or to change the size of one or more of the qtrees within. With the report above, there is more work involved to lookup that data in another report (qtree or quota report of via SysMan, etc). Something that might look like:

Object ID Volume Aggregate Storage Server Used Committed Committed (%) Total/Max Size

--------- ----------------- --------- --------------- ------------ ------------ ------------- --------------

3910 proj10010c n04_sata atxvs01 219495404 734003200 139.0 527958016

Qtree Space Limit

qtreeNameOne 99999999

qtreeNameTwo 99999999

qtreeNameThree 9999999

Qtree Space Limit

qtreeNameOne 99999999

qtreeNameTwo 99999999

Qtree Space Limit

------------------- ------------

... ETC ...

QUESTION: Is anyone aware of a standard or custom OCUM report, or even a report based on direct NMSDK calls, that provides something like this? (something Linux/bash/perl based that could be cron'ed is preferred)

All the reports I find seem to be flat reports about aggregates, volumes, qtrees or quotas but never a cascading report showing them nested within each other to address the above need.

We are considering taking some .txt or .csv output from a couple of standard OCUM reports and writing something custom but thought I'd check here first.

Hi David,

This kind of reporting is not possible with OCUM. But the OnCommad Reports can do this as its a data warehouse solution. But unfortunately this OCR does not support clustered ontap. A later version of OCR will allow you to do the same.

Thanks Adai,

I ended up coming up with a shell script (kludge) that merges two (2) standard OCUM 5.1 Clustered Mode reports. They are the generated with:

# dfm reports view volumes-quota-committed ... which shows volumes over and under committed in related qtree quotas

# dfm reports view qtrees-capacity ... which shows the qtress within the volumes and much much they are being used

The shell script generates these standard reports in comma separated (.csv) format and then use cat/grep/awk to merge them into something than can be further formatted in Excel. If I can figure out how to upload an attachment here I'll share.
