WRITE ATTRIBUTE
The parameter list will have the format shown in Table 6-103. Attributes will be sent in ascending numerical order.
If the attributes are not in order, no attributes will be changed and the WRITE ATTRIBUTE command will be
terminated with a CHECK CONDITION status. The sense key will be set to ILLEGAL REQUEST and the ASC will
be set to INVALID FIELD IN PARAMETER LIST.

The PARAMETER DATA LENGTH field will contain the number of bytes of attribute data and will be ignored by the
logical unit.
The format of the attribute is described later.
If there is not enough space to write the attributes to the medium auxiliary memory, no attributes will be changed
and the WRITE ATTRIBUTE command will be terminated with a CHECK CONDITION status. The sense key will
be set to ILLEGAL REQUEST and the ASC will be set to AUXILIARY MEMORY OUT OF SPACE.
If the medium auxiliary memory is not accessible because there is no medium present, no attributes will be
changed and the WRITE ATTRIBUTE command will be terminated with a CHECK CONDITION status. The sense
key will be set to NOT READY and the ASC will be set to AUXILIARY MEMORY NOT ACCESSIBLE.
If the Medium Auxiliary Memory has failed (e.g. bad checksum) the WRITE ATTRIBUTE command will be
terminated with a CHECK CONDITION status. The sense key will be set to MEDIUM ERROR and the ASC will be
set to AUXILIARY MEMORY WRITE ERROR.
If the WRITE ATTRIBUTE command parameter data contains an attribute with an ATTRIBUTE LENGTH field set
to ZERO, then one of the following actions will occur:
If the attribute state is unsupported or read only, no attributes will be changed and the WRITE ATTRIBUTE
command will be terminated with a CHECK CONDITION status. The sense key will be set to ILLEGAL REQUEST
and the ASC will be set to INVALID FIELD IN PARAMETERLIST;
If the attribute state is read/write, the attribute will be changed to the nonexistent state. The attribute will not be
returned in response to a READ ATTRIBUTE command and not reported by the read ATTRIBUTE command with
ATTRIBUTE LIST service action; or
If the attribute state is nonexistent, the attribute in the WRITE ATTRIBUTE command parameter list will be
ignored; this will not be considered an error.
If any of the following conditions occur, no attributes will be changed, the WRITE ATTRIBUTE command will be
terminated with a CHECK CONDITION status, the sense key will be set to ILLEGAL REQUEST, and the ASC will
be set to INVALID FIELD IN PARAMETER LIST.
If the parameter data attempts to change an attribute in the read only state.
If the parameter data contains an attribute with INCORRECT ATTRIBUTE LENGTH field contents; or
If the parameter data contain an attribute with unsupported ATTRIBUTE VALUE field contents.
