Troubleshooting and Help
When a failure occurs, the Scalar 100 firmware performs error recovery and reporting. Error
reporting includes Service Action Codes (SACs), Operator Intervention Messages, and Operator
Information Messages. All of these messages are discussed and explained here.
Service Action Codes
If a failure requires operator service, a two-byte Service Action Code (SACs) is generated and
displayed on the Operator Panel. These codes indicate a specific task that should be taken. Table
12-1 on page 12-87 lists each SAC and the recommended actions.
The two-byte SAC definition is generated as follows:
nn represents the Service Action Code
xx represents the modifier to the Service Action Code
00 represents the Main Controller
10 represents the Picker Controller
20 represents the Display Assembly
3x represents the Drive Module
x represents the Drive ID
40 represents SCSI Controller
50 represents Remote Management Unit (RMU)
