Hi All, This is my first post, so please be gentle. Not sure if the screen grabs will work or not and I hope I have removed any IP addresses etc.

Basically we upgraded our 8.3.2 CDOT systems to 9.1P1 at the weekend (1 x Fas 2552 & 2 x FAS8040) We then started getting the below email on every snapmirror update;

-----Original Message----- From: Sent: 25 March 2017 14:07 To: Subject: ukhc3-ntap-b: smc.snapmir.update.fail [LOG_ERR]

Snapmirror_error log shows these "delete failed" errors;

This is confirmed by doing a snap list;

ukhc3::> snap list mv_ukliss_cifs_scarchive_t4r2 snapmirror.c677ecdf-3df5-11e6-86a9-00a098a01c55_2158347365.2017-03-26_080500 3.16MB 0% 0% snapmirror.c677ecdf-3df5-11e6-86a9-00a098a01c55_2158347365.2017-03-26_090500 2.93MB 0% 0%

But the audit log confirms they are being deleted an hour later (confirmed time and zone all correct);

Relationship is also healthy in oCUM [cid:image001.png@01D2A616.5C0DB820]

However, this line is present in the snapmirror audit log; Sun Mar 26 07:05:00 BST 2017 CreateSnapshotDest[Mar 26 07:05:00]:18916a2e-9dae-11e6-b319-00a098a01c55 Operation-Uuid=93851169-93b6-4067-abfb-9948c09920c8 Group=none Operation-Cookie=0 action=End source=ntap-cl1-svmcifs:v_ukliss_cifs_sclive_t4r2mv destination=ukliss-ntap-cl1-svmcifs_DR:mv_ukliss_cifs_sclive_t4r2 status=Success Note=Scheduled update operation is queued.

Success but queued?

Just to see if it was an issue with the upgrade I have created multiple test relationships; Local Aggr1 to aggr2 In reverse Between the 2552 & the 8040's Between the 8040's

but getting the same issue;

Indeed at this point I have come to the same conclusion that we have hit the bug: 1042534 http://mysupport.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=1042534

Has anyone else experienced this? Or can offer up some useful advice as to our next steps.

Currently this system is only partially in production as a mv target, so the email spam is not too bad, but we plan to add many relationships very soon.

Kind Regards,

Chris.
