Diagnostics

• SCSIDISK2
• SYSMAP
• IOMAP
At Power-On, the LED turns on until the power-on sequence is completed and then turns
off.
If Auto-Spin Up is enabled, the Power-On sequence includes execution of the Spin Up
sequence, calibrating the head positioning electronics, and testing of the read/write sys-
tems. (DEFAULT setting)
If Auto-Spin Up is not enabled, the Power-On sequence includes the execution of the
Spin Up sequence only.
A flashing LED (approximately 1 Hz) indicates that the controller has failed all or a por-
tion of the internal diagnostic tests.
After power-on diagnostics have completed, the LED functions as an activity light and
will go on any time the disk drive is executing a command, reading, or writing. If the
LED is off, the drive is idle.
