Quantum Scalar Intelligent Libraries SCSI Reference Guide Guide 29
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. (Note: This flag is not supported by the
Scalar i40 and Scalar i80 libraries.)
Flag 17: Mailbox Mechanical Problem (C) - This flag is set when a mailbox station mechanical problem
is detected.
Flag 23: Library Scan Retry (W) - This flag is set when a high retry count threshold is passed when
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.
Flag 27: Cooling Fan Failure (W) - This flag is set when a cooling fan has failed within a library
component. (Note: This flag is only supported by the Scalar i40 and Scalar i80 libraries.)
Flag 28: Power Supply Failure (W) - This flag is set when a redundant power supply has failed within
the library. (Note: This flag is only supported by the Scalar i40 and Scalar i80 libraries.)
Flag 32: Barcode Label Unreadable (I) - This flag is set when a tape cartridge barcode label could not
be read. (Note: This flag is only supported by the Scalar i40, Scalar i80, and Scalar i500 libraries.)
