TODO(lucasagomes): Write about privilege level .. TODO(lucasagomes): Write about force boot device +Vendor Differences +~~~~~~~~~~~~~~~~~~ + +While the Intelligent Platform Management Interface (IPMI) interface is based +upon a defined standard, the Ironic community is aware of at least one vendor +which utilizes a non-standard boot device selector. In essence, this could be +something as simple as different interpretation of the standard. + +As of October 2020, the known difference is with Supermicro hardware where +a selector of ``0x24``, signifying a *REMOTE* boot device in the standard, +must be used when a boot operation from the local disk subsystem is requested +**in UEFI mode**. This is contrary to BIOS mode where the same BMC's expect +the selector to be a value of ``0x08``. + +Because the BMC does not respond with any sort of error, nor do we want to +risk BMC connectivity issues by explicitly querying all BMCs what vendor it may +be before every operation, the vendor can automatically be recorded in the +``properties`` field ``vendor``. When this is set to a value of +``supermicro``, Ironic will navigate the UEFI behavior difference enabling +the UEFI to be requested with boot to disk. + +Example:: + + baremetal node set <UUID or name> \ + --properties vendor="supermicro" + +Luckily, Ironic will attempt to perform this detection in power +synchronization process, and record this value if not already set. + +While similar issues may exist when setting the boot mode and target +boot device in other vendors' BMCs, we are not aware of them at present. +Should you encounter such an issue, please feel free to report this via +`Storyboard <https://storyboard.openstack.org>`_, and be sure to include +the ``chassis bootparam get 5`` output value along with the ``mc info`` +output from your BMC. + +Example:: + + ipmitool -I lanplus -H <BMC ADDRESS> -U <Username> -P <Password> \ + mc info + ipmitool -I lanplus -H <BMC ADDRESS> -U <Username> -P <Password> \ + chassis bootparam get 5 + .. _IPMItool: https://sourceforge.net/projects/ipmitool/ .. _IPMI: https://en.wikipedia.org/wiki/Intelligent_Platform_Management_Interface .. _BMC: https://en.wikipedia.org/wiki/Intelligent_Platform_Management_Interface#Baseboard_management_controller |
