Thanks to Douglas Palmer, Frank Fvrster, Louis C. Watta, Jon Hudson. General consensus is that FC link errors are not usual. I will check driver/fcode levels (and fcaw.conf), as I doubt it is hardware-related (cables are new, and we caught errors on several links, not on a particular one). --- Sebastien DAUBIGNE sdaubigne@bordeaux-bersol.sema.slb.com <mailto:sdaubigne@bordeaux-bersol.sema.slb.com> - (+33)5.57.26.56.36 SchlumbergerSema - SGS/DWH/Pessac -----Message d'origine----- De: DAUBIGNE Sebastien - BOR ( SDaubigne@bordeaux-bersol.sema.slb.com ) Date: lundi 5 mai 2003 14:06 @: 'veritas-vx@mailman.eng.auburn.edu'; 'sunmanagers@sunmanagers.org' Objet: FCAL Link Down Our server (E6500) randomly (less than 1/month) catch link errors on one of its FCAL link (JNI FC64-1063) to an IBM array (ESS 2105-800). The link goes offline during one second, then it resets and goes up. This does not produce any downtime as the link is multipathed with Veritas DMP, so the errors are transparent. But I'm just curious as if this type of error is usual for FCAL or if it is a consequence of any bug/misconfiguration/malfunction ? Here is the syslog trace, I will summarise.
