Logout iscsi when doing io, then login in target which lead that :
1. lsscsi will show the device path as '-'
2. lsblk show the device sda as prev login's device.
3. The device function have change. fio cannot do libaio+direct=1, only libaio+direct=0 But at the beginning before logout,we can do libaio+direct=1 and libaio+direct=0.
4. Even logout/login multple times, the case always be same.
5. We can ls /dev/sda, but when echo 1 > /sys/block/sda/device/delete,
   report that "no such file or dir"
6. Now need reboot system to continue use the /dev/sda in order to test or use the iscsi disk.
