ABSTRACT:
In described embodiments, a method of generating an identifier for a disk includes the steps of requesting an ASCII identification string for the disk and generating a padded string by processing the ASCII identification string into a predetermined number of bytes. The padded string is divided into portions and an encoded value is generated for each portion. The two or more encoded values for the portions are combined into a candidate value compatible with a World-Wide Name (“WWN”). The candidate value is compared to a list of previously generated candidate values and if the candidate value differs from the values in the list, the candidate value is included in the list of generated values and the candidate value is provided as the system-wide name for the disk.
