Attributes for eckd
You can find the attributes for re-IPL type eckd in the /sys/firmware/reipl/eckd sysfs directory.
- bootprog
- Boot program selector. Used to select the boot configuration in the zipl menu (if available).
- br_chr
- Specifies the cylinder, head, and record of the boot record location as comma separated values,
br_chr <c>,<h>,<r>. Alternatively, specifying "auto" makes the bootloader determine the boot record location. This is the default.
- 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.
- device
- The CCW device bus-ID of the DASD. For example,
0.0.7412or0.1.510a - loadparm
- Up to eight characters for the loadparm. This value is interpreted by the bootloader.
- scp_data
- Kernel parameters to be used for the next re-IPL from the ECKD DASD.
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.
