I've created two LUNs.  firs lun is 2047GB and working properly as data domain. but when i try to add second lun  as second data domain, i get this error on server:

error shows that second lun is very big device, but i've created second lun as 10GB for test.

BTW: is there any good documentation for ovirt and FC in detail. all administration docs are using GUI ... .
