96122 • Revision: F
A 2-byte field which represents the TapeAlert Flag number.
Disable Update is always 0, which indicates that the target updates the log
parameter value instead of the initiator.
Disable Save is always 1, which indicates saving the log is not supported.
Target Save Disable is always 0.
Enable Threshold Comparison is always 0.
Threshold Met Criteria is always 0.
The library returns 0 indicating it is not used.
List Parameter is always 0, which indicates the log parameter is a data counter.
Parameter Length is always 0x01. All are 1-byte flags.
A value of 0x01 indicates that the flag the Parameter Code is pointed to is
active; all other values are off.
lists information about the TapeAlert flags. Flags are:
Description
Set when the library cannot communicate with a tape
drive. This does not cause the library to stop operating.
Set when the servo control mechanism breaks lock.
The various causes are when the hand positioning on
the column fails or when the hand fails.
Set when the library has a hardware fault.
Set when camera initialization, calibration, or
mechanical initialization test fails.
Set when the library might have a hardware fault.
Set when a corrupted SCSI command is sent to the
library from an initiator. Currently, this flag is set
when a parity error is detected on the SCSI bus.
Set when a library hardware failure is predicted.
Set when preventive maintenance is required.
