sc 4.1 snapmirror update on a qtree-based-snapmirror fails

Hi all,

starting with V4.1 of SC a QBSM (qtree based snapmirror) is not working.

Error messages SCF-00017

Testing same with volume based snapmirror is working without any issue.

Thanks

Harald,

Qtree SnapMirror is not supported in Snap Creator.

Traditionally it has worked, but it has never been a supported configuration.

Lots of changes to this code were needed for clustered Data ONTAP 8.2 support in Snap Creator 4.1.

Apparently one of these changes broke QSM.

Since it wasn't supported it wasn't in our group of test cases and we were not aware that it broke until after the 4.1 release.

Engineering and Product Management are evaluating the options at this time.

Sorry for the inconvenience.

Re: sc 4.1 snapmirror update on a qtree-based-snapmirror fails

Hi John,

thanks for the quick response.

We are using DATA ONTAP 8.1p3 7mode  no CDOT. Fact of using qtree's is given by the application itself so we don't have the chance of easily change to volume base snapmirror.

I'm aware that no QBSM is supported with CDOT .....

I'm a little bit wondering, because SC 4.0 it's definitly working without any issues .... but SC 4.0 doesn't support HANA plugin ....

Thanks,

Harald

Re: sc 4.1 snapmirror update on a qtree-based-snapmirror fails

Hi John,

we have the same problem, we use Ontap 7mode and want to migrate from SC3.5.1 to 4.1 and we use qtree snapmirror too. With 3.5.1 it works, but in v4.1 it fails. Is there a plan, when we can use SC with qtree snapmirror?

Regards

Do you have a case open by chance?

I'm trying to get justification for having this fixed, but I'm having trouble finding open cases on this issue.

Community posts don't seem to count as much as I generally can't tie them back to customer names.

Thanks,

John

We have also been bitten by this. One of our customers used this, and had to script around it after I learned it was never officially supported.

Since you are interested in real case numbers I have just reported this in case 2005183088.
