Methods of Receiving Errors and Messages

Use Table 14 as a guide for identifying error codes and message codes reported by the Ultrium 2 Tape Drive, its enclosure (if applicable), or the server.

Note: The codes on the single-character display have different meanings, depending on whether they display during normal operations or while the drive is in maintenance mode. Codes that occur during normal operations are defined in Table 15 on page 67. Codes that occur while in maintenance mode are defined in Table 9 on page 36.
