Abstract
In the method, a logical unity is queried with a first command requesting first identifier data, to determine whether a unique identifier (UID) for the logical unit can be constructed based on the first identifier data. If a UID cannot be constructed from the first identifier data, the logical unit is queried with a second command requesting second identifier data, to determined if a UID can be constructed based on the second identifier data. If a UID cannot be constructed based on the second identifier data, the logical unit is queried with a third command requesting third identifier data. Information is extracted from the first identifier data and from the third identifier data and a UID is generated based on the extracted information.
