Creating LUN with ID greater than 255 gives error

[linonymous]

Following were the steps:

• clone the latest repo
• built the rpm using 'python setup.py bdist_rpm'
• removed earlier rpm and installed the new one
• performed creation of 300 LUNs

following is the error
Traceback (most recent call last):
File "a.py", line 16, in
l = LUN(tpg, i, f)
File "/usr/lib/python2.7/site-packages/rtslib_fb/target.py", line 527, in init
self._create_in_cfs_ine('create')
File "/usr/lib/python2.7/site-packages/rtslib_fb/node.py", line 74, in _create_in_cfs_ine
% self.class.name)
rtslib_fb.utils.RTSLibError: Could not create LUN in configFS

am I missing something?
