IO21591: 4800-7X3 BIOS DOESN'T FLASH BIOS IF BOOT IS FROM HDD

 

APAR status

  • Closed as program error.

Error description

  • cmvc 24979.1
ASM to an OS level that includes a new level of BIOS for the
terminal
and reboot the controller(s).
Power on two 723 systems.
The 723 system without the hard drive recognizes the new OS
level and flashes.
The 723 system with the hard drive, continues to boot from the
hard drive,
it never switches to PXE, therefore it never flashes the BIOS.

Local fix

  • 



Problem summary


    

  • The OS should detect that the OS level has changed and trigger a
PXE load.
The current assumption is that an ASM would cause a cold boot as
a result of
the enhanced layer changing, but that may not always be the
case.

    



Problem conclusion


    

  • Add the product control file to the "load trigger" file. This
would force a
cold boot on each ASM.
