logs, and start troubleshooting. Once the IOPs are joined then it
is time to power on the CEs.
3. Power on CE1 – Only power one CE at a time. As CE1 is
powered on, the POST and boot operations can be watched by
changing the console switch and SSDL. Shortly after the MIC is
detected in CE1, watch the Marathon Manager on one of the
IOPs to see the color changing sequence of CE1 while it is
booting into Windows NT. If CE1 goes to "green" and
Windows NT is running, then move on to CE2. If CE1 does not
boot, then check the NT error logs on the IOPs and start
troubleshooting.
4. Power on CE2 – Short after POST, it will not boot Windows NT
from the disks, but instead it will synchronize with CE1. It is
easy to see when the synchronization is taking place; the
synchronizing status is shown on the Marathon Manager on the
IOPs and CE1 is "frozen" while CE2 copies the contents of
Processor and System Memory. During synchronization the
source CE "freezes" for approximately 15 – 20 seconds per 256
MB of system memory; 1 GB of memory should be
synchronized in just over a minute.
