If you encounter problems when running the IBM TotalStorage LTO Ultrium 2 Tape Drive, refer to Table 13. If the problem is not identified in Table 13, refer to “Methods of Receiving Errors and Messages” on page 66. The color and condition of the status light may also indicate a problem. For more information, see “Status Light” on page 32.
