		+
		+	The fix is a little involved and requires modifying the file: /usr/bin/datera_storage_info.py. Please back this file up just in case before you modify it :)
		+
		+
		+	there is a section which has
		+
		+	<python>
		+	if system_vendor == SUPERMICRO or \
		+	DATERA in system_vendor or \
		+	"Dell Inc" in system_vendor:
		+	</python>
		+
		+	it needs to be changed to:
		+
		+	<python>
		+	if (system_vendor == SUPERMICRO or \
		+	DATERA in system_vendor or \
		+	"Dell Inc" in system_vendor) and hasLsiController():
		+	</python>
		+
		+
		+
		+	This will make sure that it does not try to apply the default profile for super micro unless it also sees the LSI controller. In order for that modification to work we also need to add the function to find the LSI controller. The below function should be added to the same file "/usr/bin/datera_storage_info.py” just above "def main():”. There should be two spaces before and after this new function you add.
		+
		+	<python>
		+	def hasLsiController():
		+	output = execute_command([LSPCI,
		+	"-D"])
		+	if output[0] != 0:
		+	return False
		+	for line in output[1].splitlines():
		+	if 'LSI' in line and 'controller' in line:
		+	return True
		+	return False
		+	</python>
		+
		+
		+	Indentation is also important in python. To be 100% sure this works you can run the command by itself by executing '/usr/bin/datera_storage_info.py’ it should print out a bunch of information about the disks and not exit with error. If there is an error its probably indentation.
		+
		+	Please note, this needs to be done on each of the nodes, and for good measure I generally make the change on all the nodes in separate terminals, and then when its all done I quickly save them all, just to be sure they are all in sync and seeing the same thing at all times.
