Chapter 3. Error Sense Information Sense Data For a description of Sense data, see “ Sense Data Format ” on page 60. Sense Data Management The drive maintains three types of Sense data: Current Sense The Sense data associated with the last command received from the initiator .
Persistent Errors When errors occur that prevent tape operation, they are reported persistently until the problem is cleared. For medium-related errors (usually reported with a Sense Key of 3), the error is reported until the cartridge is successfully unloaded.
Chapter 4. Sense Keys and Additional Sense Note: If temporary error reporting is enabled, many combinations of the Additional Sense Code and Additional Sense Code Qualifier (ASC/ASCQ) are possible.
T able 109. Sense Keys and Additional Sense (continued) Sense Key Additional Sense (ASC/ASCQ) Explanation Medium Error (3h) Write Error (0C00h) A WRITE operation has failed. This is probably due to bad media, but may be related to hardware. Medium Error (3h) Unrecovered Read Error (1 100h) A READ operation failed.
T able 109. Sense Keys and Additional Sense (continued) Sense Key Additional Sense (ASC/ASCQ) Explanation Illegal Request (5h) Medium Removal Prevented (5302h) An UNLOAD command has failed to eject the tape because medium removal has been prevented.
T able 109. Sense Keys and Additional Sense (continued) Sense Key Additional Sense (ASC/ASCQ) Explanation V olume Overflow (Dh) EOM (0002h) A WRITE or WRITE FILE MARKS command failed because the physical end of tape was encountered. A READ or SP ACE command encountered EOM.
Chapter 5. Attachment Features T ypes of Interface Attachments The Ultrium T ape Drive communicates with servers that use SCSI parallel or Fibre Channel interfaces. The interfaces share certain tape LUN behaviors, but also possess unique features. This chapter describes the common and unique features of both types of interfaces.
Attention Check Condition from each initiator gets a Check Condition status, with Unit Attention sense data for the reset. However , other commands may not be processed until the internal state of the drive has been reset. Any commands that allow Disconnects and cannot be processed are accepted and queued until the drive is ready to process them.
T able 1 10. Abort Condition Handling (continued) Command Abort Processing RECEIVE DIAGNOSTIC RESUL TS None. RELEASE UNIT The command completes. REPORT DENSITY SUPPORT None. REPORT LUNs None. REQUEST SENSE Sense data is discarded. RESERVE UNIT The command completes.
Multi-initiator Support SCSI-attached drives support a maximum of two initiators on the same bus. Fibre-Channel-attached drives support a minimum of two initiators.
Features of the SCSI Interface The Ultrium T ape Drive ’ s SCSI parallel interface features the following: v LUN identification v Bus parity errors v Disconnect strategy v Messages LUN Identification Identify messages are used to identify the LUN to which an initiator is connecting and to identify which LUN is reconnecting to an initiator .
Messages Message Out T able 1 12. Supported Outbound Messages Name Code Support Abort 06h An abort condition is generated (see “ Abort Handling ” on page 94). Bus Device Reset 0Ch A reset condition is generated (see “ Abort Handling ” on page 94).
Message In T able 1 13. Supported Inbound Messages Name Code Support Command Complete 00h This message is sent by the drive at the end of the Status phase to indicate that a command is complete. Once the message is sent, the drive releases the bus and goes to Bus Free.
Extended Messages T able 1 14. Supported Extended Messages Name Code Support Synchronous Data T ransfer Request 01h The default mode is for the drive to never initiate a Synchronous data transfer negotiation. The initiator is expected to do so. Since this mode is most important at power-on, no SCSI method of changing this mode is provided.
Features of the Fibre Channel Interface The Ultrium T ape Drive Model T200F (Fibre Channel drive) is an Arbitrated-Loop-only device (also known as an NL port). The drive supports Fibre Channel Arbitrated Loop (FC-AL) protocol, and uses Class 3 Service frames.
