· Performs a mode select to temporarily to set the TapeAlert test bit. This will cause TapeAlert polls to return sense
information indicating a false TapeAlert Error.
· Polls the device. It will return sense information 5D FF, which will be reported as "TapeAlert FALSE (test) predictive
failure alert."
· The mode page will be restored in order to disable TapeAlert testing.

Frequently Asked Question:
Q.How do I safely generate a TapeAlert error that does not require breaking something.
A.Most devices that have TapeAlert capability set off an alert if you load invalid media into the device. For
example, we have some DDS4 media which is not supported in one of our HP C1533A tape drives. In order to
generate an error, we stick the DDS4 media in the device and the HP will reject it shortly after the cartridge is
tensioned. Then we poll it. The resulting message will have, " Unsupported Format - You have loaded a
cartridge of a type not recognized by this tape drive.",
Q. What will be returned if the device does not support this feature?
A. The program will report: "Tape Alert test failed -- Device does not support this feature. No changes were
made."
Q. What if I have more than one TapeAlert condition?
A. The program will report all status text. It will look at whether each message is critical, an error, or a warning and
use the worst-case state to classify the warning for the system's event log.
Q. What message strings are returned?
A. The strings below are defined by the software. Not all tape/changer devices have the capability to report all of these
messages.
· Read Warning - The tape drive is having problems reading data. (No data lost, but reduction in
performance.)
· Write Warning - The tape drive is having problems writing data. (No data lost, but reduction in
