5.8.5 TapeAlert Page (2Eh)

This page returns results of the tape drive's on-going self diagnosis, so that the tape drive's
behavior can be monitored and high reliability ensured. The TapeAlert page is read from the
tape drive at the beginning of each READ/WRITE activity, after any fatal errors occur during
a READ/WRITE, at the end of any tape cartridge when the READ/WRITE activity continues
onto another tape cartridge, and at the end of each READ/WRITE activity. The flags (Table
5–26) are set or cleared by the tape drive when the failure or corrective action occurs.
