Phase Change (Stand-By to Init)
The phase change from Stand-By to Init is called Crossing the Power boundary. This is
achieved by pushing the power button on the Operator Panel or by typing the keyword
power at the Stand-By prompt (>). Note that if you type power while the power button is not
pushed in, nothing happens until you press the power button. In this case, the power
command has been taken into account by SystemGuard, and you don't have to reenter it.
The power command is the default power on command sequence, which you can change
from the maintenance menu or AIX service aids.
SystemGuard, checks for a special downloadable diskette (if in Service mode), checks the
Flash EEPROM, and then produces an output. The following is an example of what appears:
#
DO YOU WANT TO UPDATE FLASH FROM LINE S2[y/n]? n
The message FLOPPY NOT READY! means that there is no specific downloadable diskette
in the diskette drive.
Note: This message is only displayed when IPLing in Service mode.
The special diskette could be:
Code to be downloaded into Flash EPROM
Code to change the VPD in the EEPROMs of the SMP system
