When a memory dump has been requested the power LED will blink quickly
(about 10 flashes per second) to indicate that the dump has been started. This
blinking will cease after about a minute whether or not the dump is complete,
and the LED will return to its steady, lit state until the system turns off or reboots
when the dump is complete.
The memory dump file can be viewed by entering the the operating system
command:
sysdumpdev -L
The disk drive LED lights whenever the hard disk drives within the server are being
used.
The disk drive LED also provides basic system diagnostic information:
If no memory can be found as the system boots, the disk drive LED lights and
the system stops the boot process.
If an error is detected in the firmware boot program, this LED lights and the
system stops, and the diskette activity LED begins blinking. This condition
indicates that the system is requesting a Firmware Recovery Diskette, which
should be made to facilitate resolution of system problems. For instructions on
creating a Firmware Recovery Diskette, see Chapter 5, “System Management
Services” on page 5-1.
