TapeAlert refers to the capability of a tape device to provide detailed diagnostic information using the ANSI standard interface, conveniently called TapeAlert. Many modern SCSI and Fibre Channel tape drives support this feature. In general, the more expensive and robust a tape or auto changer is, the higher the probability it will have this feature.
Although the ANSI specification defines 64 flags, (click here to see it) several of them are reserved for future use. In addition, not all flags are used by all tape devices. See the table below for details. SMARTMon-UX reports all of the flags. In order to poll tape devices automatically, invoke the program with the -X option and be sure to pass it the physical device names for your tape devices. If the tape does not support TapeAlert, the program will tell you and move on.
If you wish to view the TapeAlert-related capabilities of your tape or auto changer, invoke the program with the -X+ option. This will cause it to report all supported and unsupported TapeAlert features.

In the situation above, there are two tape drives attached. The Tandberg drive has full TapeAlert capability and including the ability to report to a calling program programmatically which features it supports. The HP drive also supports TapeAlert, but it is not smart enough to let a program know exactly what features it supports.
Be sure to refer to the ANSI specification images to know exactly what each message means and whether they are informational, warnings, or critical messages.
If you invoke SMARTMON-UX with the -X option, it will poll tapes at the specified polling periods and produce a message such as: \\.\TAPE0 polled at Sun Aug 18 23:19:21 2002 Status:Passed
If there was a problem, you might see: \\.\TAPE0 polled at Sun Aug 18 23:26:49 2002 Status:Not Data Grade - The cartridge is not data grade. Data written to it will be at risk.
Note that it is possible that in the event of a TapeAlert, you will get more than one message per polling cycle.
