It seem like the storage was seen, then went away and then came back. Do you always get the same behaviour? Are there other messages in your log? Just post the entire log without the scsi logging on, from adapter load time to scan completion. > storage is APPLE Xserve RAID, latest firmware with lun masking activated, for this node > the 5th LUN is allowed. using add-single-device does the trick but i need a > kernel to boot from FC. here is the output after > # echo "scsi add-single-device 0 0 0 5" > /proc/scsi/scsi You can also use: echo "- - -" > /sys/class/scsi_host/host0/scan -- Patrick Mansfield
