In cinder of the latest version, the function '_get_common_lun_map_id' has a error in 1242 line in cinder/volume/drivers/infortrend/raidcmd_cli/common_cli.py. This function is as follows.
==================================================================================
def _get_common_lun_map_id(self, wwpn_channel_info):
map_lun = None
# search for free lun id on all channels
for lun_id in range(self.constants['MAX_LUN_MAP_PER_CHL']):
lun_id_is_used = False
for slot_name in ['slot_a', 'slot_b']:
for wwpn in wwpn_channel_info:
channel_id = wwpn_channel_info[wwpn]['channel']
if channel_id not in self.map_dict[slot_name]:
continue
elif lun_id not in self.map_dict[slot_name][channel_id]:
lun_id_is_used = True
if not lun_id_is_used:
map_lun = lun_id
break
# check lun id overflow
elif (lun_id == self.constants['MAX_LUN_MAP_PER_CHL'] - 1):
msg = _('LUN map has reached maximum value [%(max_lun)s].') % {
'max_lun': self.constants['MAX_LUN_MAP_PER_CHL']}
LOG.error(msg)
raise exception.VolumeDriverException(message=msg)
return map_lun
==================================================================================
It should change "elif lun_id not in self.map_dict[slot_name][channel_id]:" into "elif lun_id in self.map_dict[slot_name][channel_id]:", or you will find that lun_id is always used although it is not used in fact.
Since this error exists, we cannot attach the infortrend type volume to a instance. And we will encounter the exception of the overflow of lun id. The log is as follows.
