Behavior at Occurrence of Error
The CPU/IO module to be started first is determined depending on the primary/secondary status of modules
when the server was shutdown the last time.
At the first startup after AC OFF, the CPU/IO module (0 or 1) powered on first is managed as primary, and the
module powered on later is managed as secondary.
If POST or OS startup does not complete normally, the server will reboot itself automatically.
At the time of reboot, the CPU/IO module that was secondary before reboot is determined as primary module,
and POST or OS runs on that module (switching of boot pair).
If POST does not complete normally on both CPU/IO modules, the server will stop with the state of DC OFF or
POST halts with an error message displayed.
The following devices are connected to the primary CPU/IO module. When one CPU/IO module is disconnected
because of a failure, the remaining module is selected automatically to continue operating.
•
VGA (display)
•
USB device (keyboard, mouse, server switch unit, Flash FDD, optical disk drive)
Important
•
If the Flash FDD is connected, the drive letter may change from A to B by
switching CPU/IO modules. Changing of the drive letter does not affect the
operation of the server. If the drive letter is changed, access the Flash FDD with
the changed drive letter.
•
The drive letter of the optical disk drive is re-assigned automatically. The unused
letter is assigned to the drive in the order of D to Z. If you want to set the fixed
drive letter to the optical disk drive, specify the letter which is not assigned in
the order of D to Z after setting the hard disk drive letter.
