afalk, EUI format must be supported by vendors. In sense target must be configured in eui format.

Are you able to go to your ISCSI HBA within "Storage Adaptors" (Hardware/Software), select "Properties", then "Configure" Where it says ISCSI name will be the name of the IQN name, change this to the EUI name ?

Yes , eui value calculated as below:

EUI (extended unique identifier). Includes the eui. prefix, followed by the 16-character name. The name includes 24 bits for the company name assigned by the IEEE and 40 bits for a unique ID, such as a serial number.

How to get 16-character name ?  is it possible to caluculate from iqn no ?

Sorry if i am wrong

eui.0123456789ABCDEF is not establishing the connection. There is some procedure available to calculate the 16 bit hexadecimal value.

If you keep software iscsi initatior as iqn and target as eui , are you able to map it.
