Can not delete iscsi harddisk

[ED]

I have some trouble with deleting an iscsi disk in virtualbox. Also it is not possible to add the same iscsi disk to another virtual server. It does not matter if the first is powerd of or not. I get an error because a hard disk '192.168.1.8|iqn.2015-11.priv.thuis:target00' with UUID {fe6776f8-25fa-4b1c-b96e-e16afd633817} already exists

What i did:

VBoxManage storageattach iscsi-client --storagectl SATA --medium iscsi --port 1 --type hdd --server 192.168.1.8 --target iqn.2015-11.priv.thuis:target00

Because i did forget to add the username password I did delete the disk using the GUI.

I try to re-enter it with:

VBoxManage storageattach iscsi-client --storagectl SATA --medium iscsi --port 1 --type hdd --server 192.168.1.8 --target iqn.2015-11.priv.thuis:target00 --username user --password pass

I get:

Cannot register the hard disk '192.168.1.8|iqn.2015-11.priv.thuis:target00' {84b04650-7ac5-4b08-852b-0e4713e88f94} because a hard disk '192.168.1.8|iqn.2015-11.priv.thuis:target00' with UUID {fe6776f8-25fa-4b1c-b96e-e16afd633817} already exists

C:\Program Files\Oracle\VirtualBox>

The disk is not in the list !!! ? Why can i not add it then ?

When i try to delete it with:

C:\Program Files\Oracle\VirtualBox>vboxmanage closemedium disk {fe6776f8-25fa-4b1c-b96e-e16afd633817}
VBoxManage.exe: error: The given path '{fe6776f8-25fa-4b1c-b96e-e16afd633817}' is not fully qualified
VBoxManage.exe: error: Details: code VBOX_E_FILE_ERROR (0x80bb0004), component MediumWrap, interface IMedium, callee IUnknown
VBoxManage.exe: error: Context: "OpenMedium(Bstr(pszFilenameOrUuid).raw(), enmDevType, enmAccessMode, fForceNewUuidOnOpen, pMedium.asOutParam())" at line 178 of file VBoxManageDisk.cpp

I have looked at the internet and forums for answers on this issue. I did not find a good solution

Is this a bug.

Or have i have to do it in some special way

I also want to use iscsi for two hosts, with one disk. If one fails i can start the other one automatically. (2 hosts one up, one down with one storage)

Thanks.

Erik
