CHAPTER 5
FIELD ACCEPTANCE
TEST PROCEDURE
Field acceptance testing is intended to demonstrate performance of the RK06 or RK07 Disk Drive
and/ or the RK611 Controller to the customer prior, to his acceptance of the equipment.
5.1 ERROR DEFINITIONS/RATES
The RK611 has five: registers that display the various error conditions that can exist in the Disk
subsystem. Table 5-1 lists the various error indications and gives an explanation of their significance.
Errors are broken down into five categories:
I. Control
2. Cartridge
3. Seek
4. Hard errors
5. Soft errors
These classifications aid in the identification of the various errors encountered in acceptance testing
only.
5.1.1 Control Errors
A control error indicates an operational aberration in the execution of command and control functions.
Any control error detected by a diagnostic program during acceptance testing indicates a hardware
malfunction that must be corrected before testing can continue.
