Do you have DS controller A connected to only one FC switch, and DS controller B connected to another switch? Two completely separate fabrics ? i.e. your host should only see one DS4x000 controller per hba. If it see both A and B over the same HBA, I think it might try to fail over from A to B on the same fiber connection you just unplugged. -jf _______________________________________________ rhelv5-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv5-list
