NOTE: When a flag is cleared by reading the TapeAlert Log page, a flag cannot be
set again until the error condition is removed (e.g., the specified corrective
action has been taken). So, for example, if the cartridge in the drive is not
data grade, once flag 8 has been cleared by the Host software reading the
Log page it cannot be set again until the cartridge has been removed. All
other methods of clearing allow the flag to be set again.
There are three types of flags, listed below in order of increasing severity:
Severity Urgent User
Intervention Risk of Data
Loss
Explanations
Critical X X
Warning X X
