Thanks, Dan. I dug around some more and found this information that I will try after hours tonight because I don't know what its impact on a live system would be. echo "scsi-qlascan" > /proc/scsi/qla2xxx/1 echo "scsi-qlascan" > /proc/scsi/qla2xxx/2 And then possibly, echo "---" > /sys/class/scsi_host/host1/scan echo "---" > /sys/class/scsi_host/host2/scan I will post my results later.
