26Description: (RW) A sysfs node that configure the error threshold for the hardware
27 isolation strategy. This size is a configured integer value, which is the
28 number of threshold for hardware errors occurred in one hour. The default is 0.
29 0 means never isolate the device. The maximum value is 65535. You can write
30 a number of threshold based on your hardware.
