POWER7 information
You might need to read the status lights on your tape drive to determine the operating status of the drive. Use the information in this topic to perform this task.

1 When used in this table, flashing refers to a 1 Hz flash rate (1 flash per second), and flashing rapidly refers to a 4 Hz flash rate (4 flashes per second). 2 Immediately following a power-on self-test sequence or drive reset, both LEDs, all segments of the single-character display, and the SCD dot will be on solid for approximately 3 seconds. 3 When a drive needs cleaning, the Fault LED will be on solid and a C will show on the single character display. In most cases, the drive will continue to function, but it should be cleaned as soon as possible. Do not ignore the indicator by cycling the power to turn off the LED. 4 Error code on single-character display is cleared when cartridge is removed from drive. 5 The Fault LED will be on solid to
indicate an over-temperature condition. If a tape is present, it
will be ejected. This LED will remain on until the drive temperature
drops below a lower secondary-temperature limit and one of the following
two conditions is also met:
6 A drive dump will be stored before the drive is powered off. The SCD light serves as a dump indicator. When this light is lit, a dump file is stored in the drive and can be retrieved. 7 Failure cannot be isolated to either a faulty drive or faulty media. 8 Error condition will be cleared when the drive is powered off. The drive is not disabled. 9 The firmware update failed and the drive is not functional. The drive boot code is in control and you should try the firmware download again. 10 When the drive is in maintenance mode, the Fault LED will be on solid and the single character display will indicate the current maintenance mode state. |
