we are testing the VServer snapmirror failover and failback process. we have multiple CIFS volumes in the VServer, each one has multiple millions files, we found the failback took a few hours to complete. According to NetApp support, the failover process will have to check the data integrity, this is why take so long to complete. it means our application will need additional hours down time. is there any way to improve the failover process? Such as to skip the data integrity check if we know the source side data is good, or kick off the data integrity check before kick off the fail over.  Please share your experience if you were on same or similar situation. thanks, ...

Hello, have an old FAS3250 running ONTAP 9.1P20 - both of these (HW and ONTAP) are long past any support. It was used for secondary backups using SnapMirror (XDP, Async) from the primary system running newer ONTAP (started with 9.8 and was updated over the years to 9.13.1P7). Few days ago I have updated the primary system to 9.14.1P2 and since then the SnapMirror does not work. I cannot update the existing relationships and cannot initialize new ones.   The error is reported on the 9.1 system smc.snapmir.update.fail: Snapmirror update from source volume 'xxx' to destination volume 'yyy' failed with error 'Failed to create Snapshot copy snapmirror.zzz.2024-04-21_090500 on volume xxx.(Failed to start operation on source.)'. Relationship UUID 'zzz'.   There is no error on the 9.14 system (nothing in the event log, did not find anything in the other logs (maybe not looking properly). Weird thing is the "snapmirror list-destinations" on the 9.14 does not return anything (the old snapmirror snapshots exists in the volumes). The cluster and vserver peer relationships seems OK (available, healthy).   I can replicate from the 9.14 system to another system with ONTAP 9.13.1P7 (tried just for the test).   Found KB article and documentation page that states this is no longer supported (since a long time) - but according to that information it should not work even before.   https://kb.netapp.com/onprem/ontap/dp/SnapMirror/How_to_check_SnapMirror_compatibility_between_ONTAP_versions https://docs.netapp.com/us-en/ontap/data-protection/compatible-ontap-versions-snapmirror-concept.html   Funny thing is all the relationships (even between 9.14 and 9.13) state Relationship Capability: 8.2 and above   Does anybody know what changed in 9.14 and if there is any workaround? (reverting the system to 9.13 would be really painful).   Thanks Harry       ... View more

Hi all, I was wondering, is there a possibility that snapcenter allows you to create a clone residing on another vserver? We have a mixed fc/iscsi environment. I think it would be nice if i could clone db's from the fc vserver to the iscsi vserver. Currently i use a powershell script to realize this as powershell has an option to change the destination vserver. The snapshots for the clones are restapi triggered. But, with lifecycle management in mind i would prefer the option complete in snapcenter itself.     ... View more

I'm using Snapcenter 4.7 and 5.0 and the REST API. I'm looking to build a front end Web app to show clone details (and other things). Where can I find a schema reference for the JSON/XML returned by the APIs? ... View more

I'm using Snapcenter 4.7 production instance and looking to test upgrade to 5.0. The problem is I need the workloads/config of prod (clones etc.) to do a real test so I have attempted taking a backup of 4.6 and restoreing to a new server with the same name but in a different domain. I cannot restore to the same domain as this would impact produciton.  After manipulating some of the XML files and folder name sof the backup I managed ot do the restore but now I cannot logon. I'm assuming this is because all the roles on the prod instance are targted at ADDS users/groups in the prod domain and my restore is to a member server in my test domain. Q: is there anyway to reset the access? ... View more
