4.15.1 Error Summary for the READ ATTRIBUTE Command

terminates the READ ATTRIBUTE command with a CHECK CONDITION status. The Sense Key is

set to NOT READY and the Additional Sense Code is set to MEDIUM NOT PRESENT.

READ ATTRIBUTE command with a CHECK CONDITION status. The Sense Key is set to NOT

READY and the Additional Sense Code is set to LOGICAL UNIT NOT READY, MAM NOT

AVAILABLE.

If the combination of volume number and partition number is not valid, the drive terminates the READ

ATTRIBUTE command with a CHECK CONDITION status. The Sense Key is set to ILLEGAL

First

Attribute

Identifier

Specifies the attribute identifier of the first attribute to be returned.

Allocation

Length

Specifies how many bytes are allocated for the returned parameter list. If the

value in this field is not sufficient to contain the entire parameter list, the drive

returns the truncated list; this is not considered an error. If the remainder of the

list is required, the application client either: 1) sends a new READ ATTRIBUTE

command with the Allocation Length field set to a large enough value to contain

the entire parameter list, or 2) uses the First Attribute Identifier field to restrict the

attributes returned.
