Shalom,

Maybe zoning is not so fine?

Seems a lot of disks have been presented to the system compounded by the fact that securepath is providing multiple paths to each disk.

I am going to assume you are attached to an EVA. For the presented LUN's did you select Path A or B Failover only when presenting them to the host?
