SCSI Commands

The supported Tape Alert flags are:

Flag 1:

Drive Communication Failure (C)

- This flag is set to indicate a drive communication failure.

Flag 2:

Library Hardware B (W) - This flag is set for any unrecoverable mechanical error.

Flag 4:

Library Hardware D (C) - This flag is set when the internal Power-On-Self-Tests (POST) fail or

when a mechanical error occurs that requires a power cycle to recover, and is not internally cleared until the
device is powered off.

Flag 13:

Library Pick Retry (W) - This flag is set when a high retry count threshold is passed when

performing an operation to pick a cartridge from a slot before the operation succeeds. It is internally cleared
when another pick operation is attempted.

Flag 14:

Library Place Retry (W) - This flag is set when a high retry count threshold is passed when

performing an operation to place a cartridge back into a slot before the operation succeeds. It is internally
cleared when another place operation is attempted.

Flag 15:

Library Load Retry (W) - This flag is set when a high retry count threshold is passed when

performing an operation to load a cartridge into a drive before the operation succeeds. It is internally cleared
when another load operation is attempted. Note that if the load actually fails due to a media or drive problem,
the appropriate TapeAlert flags should be set by the drive.

Flag 16:

Library Door (C) - This flag is set when media move operations cannot be performed because

a door is open, and is internally cleared when the door is closed.

is detected.

Flag 23:

performing an operation to scan the barcode on a cartridge before the operation succeeds. It is internally
cleared when another barcode scanning operation is attempted.

be read.
