Sense Key Meaning Explanation

0h No Sense

Indicates that there is no specific sense key information to be

reported for the designated logical unit. This occurs when a

command completes successfully or returns Check Condition

status with the FMK, EOM, or ILI bits set to 1.

1h Recovered Error

Indicates that the last command completed successfully with

some recovery action performed by the CTS.

2h Not Ready

Indicates that the CTS does not contain a data cartridge or

that the data cartridge is not loaded. Operator intervention

may be required to correct this condition.

3h Medium Error

Indicates that the command terminated with a non-recoverable

error condition that may have been caused by a flaw in the

tape.

4h Hardware Error

Indicates that the CTS detected a non-recoverable hardware

failure while performing the command or during a self-test.

5h Illegal Request

Indicates that there was an illegal parameter in the CDB or in

the additional parameters supplied as data for a command or

that the CTS is in the wrong mode to execute the command.

6h Unit Attention

Indicates one of the following:

■ The CTS has been reset (by a power-on reset, a Bus

Device Reset message, or a SCSI bus reset).

■ An initiator changed the MODE SELECT parameters since

the last command was issued to the CTS.

■ The unload button was pressed and the data cartridge was

ejected.

■ A data cartridge was inserted and automatically loaded.

■ A data cartridge was inserted and automatically ejected

because the media was incompatible with the CTS. (For

example, a metal evaporative tape was inserted, or a

160m tape was inserted in a non-XL CTS.)

■ The internal microcode (firmware) was changed.

■ A log parameter (counter) reached a specified threshold

value (assuming that RLEC bit on the MODE SELECT

Control Mode page is set to 1).

This sense key is reported the first time any command is

issued by each initiator after the condition is detected, and the

requested command is not performed. This sense key is

cleared when the next command other than INQUIRY or

REQUEST SENSE is received by the CTS. Refer to Section

3.9 for more information about the Unit Attention condition.

7h Data Protect

Indicates that a command that writes to tape was attempted

on a write-protected data cartridge. The write operation is not

performed.
