Description |
Value |
|---|---|---|
filepath |
Specifies the path of the BIOS upgrade file. |
For example, /tmp/biosimage.hpm. |
Usage Guidelines
- Before running this command, use a file transfer tool that supports SFTP, for example WinSCP, to transfer the upgrade file to the specified directory (for example /tmp) of the iBMC file system.
- Both the maintenance -d upgradebios and upgrade commands can be used to upgrade the BIOS, the difference is as follows:
- To use the maintenance -d upgradebios command, you need to power off the OS. To use the upgrade command, you can choose to power off the OS or not.
If the maintenance -d upgradebios command is used to upgrade the BIOS, the BIOS configuration and default BIOS password will be changed to the default values of the target version after the upgrade. Exercise caution when performing this operation.
After the BIOS is upgraded on the iBMC WebUI, the following information is the same as that before the upgrade:
- Date, time, and language information on the Main page
- BIOS password and startup logo
- All parameters except watchdog parameters on the IPMI iBMC Configuration page of the Advanced screen
- If the upgrade command is used, system settings will not be changed. For details, see Upgrading the Firmware (upgrade).
Example
# Upgrade the BIOS using the /tmp/biosimage.hpm file.
iBMC:/->ipmcset -t maintenance -d upgradebios -v /tmp/biosimage.hpm Please make sure the iBMC is working while upgrading. Updating... System needs two minutes time to prepare. <100%> Update successfully.
