LOS ANGELES, California (Reuters) — Los Angeles officials have asked that manufacturers, suppliers and contractors stop using the terms "master" and "slave" on computer equipment, saying such terms are unacceptable and offensive.

The request — which has some suppliers furious and others busy re-labeling components — came after an unidentified worker spotted a videotape machine carrying devices labeled "master" and "slave" and filed a discrimination complaint with the county’s Office of Affirmative Action Compliance.

In the computer industry, "master" and "slave" are used to refer to primary and secondary hard disk drives. The terms are also used in other industries.

"Based on the cultural diversity and sensitivity of Los Angeles County, this is not an acceptable identification label," Joe Sandoval, division manager of purchasing and contract services, said in a memo sent to County vendors.

"We would request that each manufacturer, supplier and contractor review, identify and remove/change any identification or labeling of equipment components that could be interpreted as discriminatory or offensive in nature," Sandoval said in the memo, which was distributed last week and made available to Reuters.

The memo did not include any suggestions for alternative labels.

Dennis Tafoya, director of the affirmative action office, said in a separate memo that an "exhaustive search" had been undertaken to find all such labels and replace them with more "appropriate" ones. A form was sent to all departments to identify equipment carrying the labels "master" and "slave" or any other offensive terms.
