Handling Procedure
1. Enable the video recording
function on the iMana 200 or
iBMC WebUI.

debugging the BIOS with the
iMana 200 or iBMC CLI, restart
the server, and save system
serial port logs. When the fault
is repeated, collect iMana 200
or iBMC logs and download
the .bin file of the BIOS.
NOTE
You can run the ipmcset -t
maintenance -d biosprint -v 1
command to print all BIOS logs.
For details, see "Querying and
Setting BIOS Print Enablement
Status (biosprint)" in the
User Guide of the required
version.
3. Restore the default BIOS
settings, and check whether
the server operates properly.
● If yes, modify the BIOS
parameters in the OS side
based on actual
requirements.
● If no, collect iMana 200 or
iBMC logs, download
the .bin file of the BIOS. For
details, see the
Guide of the corresponding
version.
NOTE
For an E9000 server, you are advised
to use the MM910 for one-click log
