> How can be single LUN access from different controllers? You cannot. AFAIK the MD3000 SAS is an Active/Passive array, and no ALUA support available. Any given LUN is controlled by one controller at a time, and all host that need to access the LUN must be connected to the controller that currently controls the LUN. When two hosts connected to separate controllers only need to access to the same LUN you get LUN trashing. E.g both hosts will issue failover in an endless loop. -- Best Regards Harald Jensås Dell EDT | NER (Sweden) Mobile: +46 701912317 E-Mail: [email protected] _______________________________________________ Linux-PowerEdge mailing list [email protected] https://lists.us.dell.com/mailman/listinfo/linux-poweredge Please read the FAQ at http://lists.us.dell.com/faq
