I think there is something wrong with your storage array. What is it? One of those little EMC arrays? > Configuring FCP disk 5006916030603a65:0000000000000000 > Vendor: DGC Model: RAID 5 Rev: 0226 > Type: Direct-Access ANSI SCSI revision: 04 It is not a zoning issue. There wouldn't be messages about sense data if the channel couldn't talk to the storage array.
