Rafal,<br><br>NetApp&#39;s definition of &quot;non-disruptive&quot; is generally not what most people consider non-disruptive :-)  It does cause nfs outages during these modes.  How much time varies by hardware, system load, etc.  The time listed by the giveback is generally less than user wall clock time.  The system may say the downtime was 45 seconds, but a time command from a client will usually be closer to 100 seconds before the filer starts responding again.  That is why I generally do snapmirror migrations and cluster failovers in the middle of the night to minimize user complaints.<br>

<div dir="ltr">Hi All.<div><br></div><div>I have two FAS3210 in 7-mode Actvie/Active. I perform takeover/gieback and see that the outage is visible for clients for nfs mounts. From your experiences should it be so? I think that information about nfs sessions and IP address are moved to the takeover node so in theory it should not be visible.</div>
