BIOS Configuration Management

iDRAC10: BIOS attribute paths and racadm set syntax are the same on iDRAC10. The Redfish BIOS endpoint is: GET /redfish/v1/Systems/System.Embedded.1/Bios

Set BIOS Attributes

Set a single attribute

racadm -r $IDRAC_HOST -u $IDRAC_USER -p $IDRAC_PASS set BIOS.SysProfileSettings.SysProfile PerfOptimized

Set multiple attributes

racadm -r $IDRAC_HOST -u $IDRAC_USER -p $IDRAC_PASS set BIOS.ProcSettings.ProcVirtualization Enabled
racadm -r $IDRAC_HOST -u $IDRAC_USER -p $IDRAC_PASS set BIOS.ProcSettings.LogicalProc Enabled
racadm -r $IDRAC_HOST -u $IDRAC_USER -p $IDRAC_PASS set BIOS.IntegratedDevices.SriovGlobalEnable Enabled

Create a BIOS config job to apply pending changes

BIOS changes are staged -- they require a config job and a reboot to take effect.

racadm -r $IDRAC_HOST -u $IDRAC_USER -p $IDRAC_PASS jobqueue create BIOS.Setup.1-1

To apply immediately with automatic reboot:

racadm -r $IDRAC_HOST -u $IDRAC_USER -p $IDRAC_PASS jobqueue create BIOS.Setup.1-1 -r pwrcycle -s TIME_NOW -e TIME_NA

To schedule for a maintenance window:

racadm -r $IDRAC_HOST -u $IDRAC_USER -p $IDRAC_PASS jobqueue create BIOS.Setup.1-1 -r pwrcycle -s 20260401020000 -e 20260401040000

The -s and -e flags set start and end time in YYYYMMDDHHmmss format (UTC).

Check job status

racadm -r $IDRAC_HOST -u $IDRAC_USER -p $IDRAC_PASS jobqueue view

BIOS Import/Export via Server Configuration Profile (SCP)

SCP allows config-as-code management of BIOS settings.

Export BIOS configuration to XML

racadm -r $IDRAC_HOST -u $IDRAC_USER -p $IDRAC_PASS get -t xml -f bios-config.xml -c BIOS

Export BIOS configuration to JSON

racadm -r $IDRAC_HOST -u $IDRAC_USER -p $IDRAC_PASS get -t json -f bios-config.json -c BIOS

Import BIOS configuration from XML

racadm -r $IDRAC_HOST -u $IDRAC_USER -p $IDRAC_PASS set -t xml -f bios-config.xml -c BIOS

The -c flag filters the SCP to a specific component. Valid component values:

Component Description
BIOS BIOS attributes only
iDRAC iDRAC configuration only
NIC Network adapter settings
RAID RAID controller and virtual disk configuration
FC Fibre Channel HBA settings
LifecycleController Lifecycle Controller settings
All Every component (default if -c is omitted)

Boot Order Management

View current boot order

racadm -r $IDRAC_HOST -u $IDRAC_USER -p $IDRAC_PASS get BIOS.BiosBootSettings.BootSeq

View UEFI boot order

racadm -r $IDRAC_HOST -u $IDRAC_USER -p $IDRAC_PASS get BIOS.BiosBootSettings.UefiBootSeq

Set boot order (BIOS mode)

racadm -r $IDRAC_HOST -u $IDRAC_USER -p $IDRAC_PASS set BIOS.BiosBootSettings.BootSeq HardDisk.List.1-1,NIC.Integrated.1-1-1,Optical.SATAEmbedded.J-1

Set one-time boot device (next boot only)

racadm -r $IDRAC_HOST -u $IDRAC_USER -p $IDRAC_PASS set BIOS.BiosBootSettings.OneTimeBootMode OneTimeBootSeq
racadm -r $IDRAC_HOST -u $IDRAC_USER -p $IDRAC_PASS set BIOS.BiosBootSettings.OneTimeBootSeqDev NIC.Integrated.1-1-1
racadm -r $IDRAC_HOST -u $IDRAC_USER -p $IDRAC_PASS jobqueue create BIOS.Setup.1-1 -r pwrcycle -s TIME_NOW -e TIME_NA

Reset BIOS to Defaults

WARNING: DESTRUCTIVE -- This resets ALL BIOS settings to factory defaults including boot order, system profile, and security settings. Verify current settings with an SCP export before proceeding.

racadm -r $IDRAC_HOST -u $IDRAC_USER -p $IDRAC_PASS set BIOS.MiscSettings.BiosDefault Enabled
