The iSCSI spec says the name is not case sensitive. The kernel and rtslib will take the capital letters and just convert it to lower case. The user space tools are ignoring the normalized name that rtslib returns and will use the name with capital letters. On deletion we then later mismatch and think we already deleted it.
We should be using the name returned from rtslib.normalize_wwn.
I will make a patch and link it here.

Here are some patches which should fix the issue:
For your existing setup with the bad name, I think you are stuck. You can manually delete everything by doing
rados -p rbd rm gateway.conf
then rebooting the iscsi gateways. When they come up it will be with a empty config and no objects.

thanks. but I found another issue.
1: I make a image in command rbd create iotest/datest --size 10G ,
2: and then I use gwcli to create an iqn, create iqn.1994-05.com.redhat:75c3d5efde0
3: and create a disk create pool=iotest image=datest size=10G which is the same name as i created in command rbd create iotest/datest --size 10G .
4: i add the disk to my iqn in command disk add iotest.datest
5: after all success, i remove the disk, in curl --insecure --user admin:admin -d disk=iotest.datest -X DELETE https://192.168.122.69:5000/api/clientlun/iqn.2017-08.org.ceph:iscsi-gw0,
6: and remove the iqn curl --insecure --user admin:admin -X DELETE https://192.168.122.69:5000/api/client/iqn.1994-05.com.redhat:myhost4
7: then I remove my image in ceph, by doing rbd rm iotest/datest
it seems ok for all I done, but when I try to come in gwcli again, it shows
Exception in thread Thread-1:

ImageNotFound: [errno 2] error opening image datest at snapshot None
KeyError: u'iotest.datest'
and gwcli cannot work again!
I find in log that the image ``` datest`` is still in config file:
"disks": {
"iotest.datest": {
"created": "2019/01/17 01:10:09",
"image": "datest",
"owner": "node3",
"pool": "iotest",
"pool_id": 7,
"updated": "2019/01/17 01:10:09",
"wwn": "f0b79a61-3470-4b2a-b9e9-f8574410fb13"
}
}
i use targetcli and it shows that the image I created iotest.datest is still there

I have suffered from this issue for a while.
I think I cannot delete any ceph image if this image ever map to an iqn in case of gwcli goes wrong.
