Last night I had those targets drop and them come back up. This appears to be happening during a backup on the host servers. My question is twofold, A) how do I turn up logging to figure out what is causing this, and B) any idea what could cause this? I know it’s not a switch issue.

I did some searching and found this thread, which only referenced the nebulous “IO storm” <o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><a href="http://openindiana.org/pipermail/openindiana-discuss/2012-May/008211.html">http://openindiana.org/pipermail/openindiana-discuss/2012-May/008211.html</a><o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Thanks in advance.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>-Nate Smith<o:p></o:p></span></p><p class=MsoNormal><span lang=CS style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span lang=CS style='color:#1F497D'>Oct 15 22:08:47 newstorm fct: [ID 132490 kern.notice] NOTICE: qlt3,0 LINK UP, portid 10000, topology Fabric Pt-to-Pt,speed 8G<o:p></o:p></span></p><p class=MsoNormal><span lang=CS style='color:#1F497D'>Oct 15 22:08:49 newstorm fct: [ID 132490 kern.notice] NOTICE: qlt0,0 LINK UP, portid 20100, topology Fabric Pt-to-Pt,speed 8G<o:p></o:p></span></p><p class=MsoNormal><span lang=CS style='color:#1F497D'>Oct 15 22:08:50 newstorm fct: [ID 132490 kern.notice] NOTICE: qlt1,0 LINK UP, portid 10100, topology Fabric Pt-to-Pt,speed 8G<o:p></o:p></span></p><p class=MsoNormal><span lang=CS style='color:#1F497D'>Oct 15 22:11:01 newstorm fct: [ID 132490 kern.notice] NOTICE: qlt0,0 LINK UP, portid 20100, topology Fabric Pt-to-Pt,speed 8G<o:p></o:p></span></p><p class=MsoNormal><span lang=CS style='color:#1F497D'>Oct 15 22:11:01 newstorm fct: [ID 132490 kern.notice] NOTICE: qlt3,0 LINK UP, portid 10000, topology Fabric Pt-to-Pt,speed 8G<o:p></o:p></span></p><p class=MsoNormal><span lang=CS style='color:#1F497D'>Oct 15 22:11:02 newstorm fct: [ID 132490 kern.notice] NOTICE: qlt2,0 LINK UP, portid 20000, topology Fabric Pt-to-Pt,speed 8G<o:p></o:p></span></p><p class=MsoNormal><span lang=CS style='color:#1F497D'>Oct 15 22:12:30 newstorm fct: [ID 132490 kern.notice] NOTICE: qlt0,0 LINK UP, portid 20100, topology Fabric Pt-to-Pt,speed 8G<o:p></o:p></span></p><p class=MsoNormal><span lang=CS style='color:#1F497D'>Oct 15 23:02:15 newstorm fct: [ID 132490 kern.notice] NOTICE: qlt2,0 LINK UP, portid 20000, topology Fabric Pt-to-Pt,speed 8G<o:p></o:p></span></p><p class=MsoNormal><span lang=CS style='color:#1F497D'>Oct 15 23:02:16 newstorm fct: [ID 132490 kern.notice] NOTICE: qlt3,0 LINK UP, portid 10000, topology Fabric Pt-to-Pt,speed 8G<o:p></o:p></span></p><p class=MsoNormal><span lang=CS style='color:#1F497D'>Oct 15 23:04:09 newstorm fct: [ID 132490 kern.notice] NOTICE: qlt0,0 LINK UP, portid 20100, topology Fabric Pt-to-Pt,speed 8G<o:p></o:p></span></p><p class=MsoNormal><span lang=CS style='color:#1F497D'>Oct 15 23:04:10 newstorm fct: [ID 132490 kern.notice] NOTICE: qlt1,0 LINK UP, portid 10100, topology Fabric Pt-to-Pt,speed 8G<o:p></o:p></span></p><p class=MsoNormal><span lang=CS style='color:#1F497D'>Oct 15 23:05:52 newstorm fct: [ID 132490 kern.notice] NOTICE: qlt3,0 LINK UP, portid 10000, topology Fabric Pt-to-Pt,speed 8G<o:p></o:p></span></p><p class=MsoNormal><span lang=CS style='color:#1F497D'>Oct 15 23:05:53 newstorm fct: [ID 132490 kern.notice] NOTICE: qlt2,0 LINK UP, portid 20000, topology Fabric Pt-to-Pt,speed 8G<o:p></o:p></span></p></div></body></html>`
