Flag		Severity Level *	Meaning
1	Read Warning	Warning	Problems reading data. There is no loss of data, but the tape
			drive’s performance is reduced.
2	Write Warning	Warning	Problems writing data. There is no loss of data, but the
			capacity of the tape is reduced.
3	Hard Error	Warning	An error has occurred during a read or write operation that
			the tape drive cannot correct: operation has stopped.
5	Read Failure	Critical	The tape medium or the tape drive is damaged. Contact a
			service representative.
6	Write Failure	Critical	The tape medium is faulty or the tape drive is damaged.
			Test the tape drive using a known-good tape cartridge. If
			the problem persists, contact a service representative.
9	Write Protect	Critical	The tape cartridge is write protected. Set the write
			protection switch to enable writing, or use a different tape
			cartridge.
10	No Removal	Informational	The tape drive is busy and the tape cartridge cannot be
			ejected. Wait for the operation to complete before
			attempting to eject the tape cartridge.
11	Cleaning Media	Informational	The tape cartridge in the tape drive is a cleaning cartridge.
			For normal tape drive data-related operations, replace the
			cleaning cartridge with a data tape cartridge.
20	Clean Now	Critical	The tape drive needs to be cleaned. Make sure that all tape
			operations have completed, eject the data tape cartridge
			and follow the appropriate steps to use a cleaning cartridge.

*Severity levels are Informational, Warning, and Critical. Informational flags provide a status-type message, Warning flags indicate that there is the possibility of loss of data, and Critical flags indicate the possibility of loss of data and that user intervention is urgently required.
