With change[1], we added a mechanism to wait for multipath device to be ready for I/O. see more info in [2]. Sometimes the connection to the storage array is slow and the multipath device doesn't get discovered during the os-brick operation. This leads to failure while waiting for the multipath device where we don't even have the multipath device populated yet in /sys/block/<dev>/holders/dm-* resulting in the following command executing and failing. 'multipath -C None' This does indicate some issue with the connection but we should not fail the operation here since we can still complete it even with a single device discovered. This is already handled in the iSCSI connector[3] with a check for the sysfs dm name being populated or not. This patch adds the same logic to FC where the dm name is not populated but we don't want to fail the operation because of slow connection.
