snapshot space consumtion -trending analysis with oncommand possible?

uwer — Thu, 05 Jun 2025 06:31:59 GMT

Hello

customer asked me recently if it is possible to get historic data of snapshot space consumption. e.g. if he starts snapshotting a volume how long will the snapshot reserve last until he has to expand the snapshot reserve. Customer is on sod thats why he asked this question.

thanks for any helpful reply

Uwe

Yes, OnCommand tracks usage of the snapshot reserve. The "Volume Snapshot Growth" report (from the classic OnCommand GUI) would be the place to start. I'm not entirely sure where this is reported in the 5.0 GUI.

In general, for any volume named "X", OnCommand has a record for "X.snapshot" which represents the snapshot reserve. We keep the same set of statistics for both the main volume and the snapshot "volume".

Hi Uwe,

There are lot of snapshot based reports in OnCommand 5.0 but they are in the operations manager console and not in the oncommand console. Pls take a look at the following GSS course which details on the reporting capability with OnCommand 5.0.For an in-depth training take a look at the GSS course for Reporting with OnCommand 5.0
