Built-In Self

Test (BIST)

Failures

During power-up, or after you push the RESET button on the display/operation panel, the array will automatically run a Built-In-Self-Test. This test thoroughly exercises array hardware and checks the following:

Controller board components and functionality

Display/operation panel functionality

Firmware code checksum

SCSI termination for single-ended arrays

You can reset the array and run BIST whenever you want to check the array internals.

Indicators

The audible alarm will sound, if enabled. After the alarm has begun to sound, it will go silent after any key is pressed. The alarm cannot be disabled in BIST mode.

A BIST error will appear on the display/operation panel. A typical BIST error looks like this:

Figure 16 Sample BIST Error Message

You have two options when a BIST error occurs:

Choose to continue with the BIST—The failing test is skipped, and the rest of BIST is run.

Choose to loop on the errorThe failing test is retried infinitely; a percentage of error will be displayed. Press SELECT to stop the looping.
