Attributes for nvme
You can find the attributes for re-IPL type nvme in the /sys/firmware/reipl/nvme sysfs directory.
- bootprog
- Boot program selector. Used to select the boot configuration in the zipl menu (if available).
- br_lba
- Boot record logical block address. Master boot record. Is always 0 for Linux®.
- clear
- A flag that controls memory clearing for a reboot from the device. Valid values are 1 to clear
memory during the boot process, or 0 to omit clearing memory during the boot process. Booting
without clearing memory is faster and it is the default.
Regardless of the setting for memory clearing, all hotplug memory is offline after the reboot.
This attribute is present only for Linux in LPAR mode on LinuxONE hardware as of LinuxONE III.
- fid
- PCIe function ID of the NVMe device. This value specifies the slot at /sys/bus/pci/slots.
- loadparm
- Up to eight characters for the loadparm.
- nsid
- NVMe name space ID. Name space IDs are assigned by NVMe disk controllers to divide a physical NVMe device into multiple logical devices.
- scp_data
- Kernel parameters to be used for the next NVMe re-IPL.
A leading equal sign (=) means that the existing kernel parameter line in the boot configuration is ignored and the boot process uses the kernel parameters in the scp_data attribute only.
