Hi Jochen,

I would have thought the snapmirror relationship would be now broken given the release differentiation? Should the R200 not require a minimum of ONTAP 7.0.4 in order to continue mirroring data from the source ( FAS3050 )?

I found ONTAP 7.0.1R1 to be quite buggy and has numerous snapmirroring bugs fixed in ONTAP 7.0.4. In particular BURT 157883 which allowed me to oversubscribe my containing aggregate.

In order to debug your existing problem, I'd advise running 'perfstat' on FAS3050 and asking Netapp Support to review the output.

perfstat.sh -f 'filername' -t 5 -i 3,0 -P flat >> 'logfile'

Regards, Philip

Hello toasters,

today we have a few problems with a FAS3050 (Ontap 7.0.4) which is very slow, as the users tell me. When i do a sysstat i see the CPU always between 40 and 60% which is not too much.

I also had a look at the ocupied space in the aggregates and it should be ok, too. According to this we have a snapmirror-relation to a Nearstore R200 (Ontap 7.0.1R1) which is very slow. The network is not the bottleneck as we have an own storagenet (1Gb Ethernet) for these systems.

I now wonder where is shall look for deeper analysis. I am a little confused right now. Perhaps anybody can help with some kind of commands different to sysstat :-)

Best Regards
