OK, hopefully just one more request; I'm trying to figure out a way to
distinguish a disk from a control LUN, since in my case (Linux iscsi target), 0
is a control LUN. Can you give me the output of:
# cat /sys/bus/scsi/devices/3:0:0:0/model
and
# cat /sys/bus/scsi/devices/3:0:0:0/type
from both your netapp target and your sun target? Here, at least, for our
"control" LUN, model returns "Controller" while for the real LUNs
model returns
"VIRTUAL-DISK", so I'm hoping I can distinguish somehow based on what is in
model, and if not that, based on type.
Thanks again for the info,
Chris Lalancette
