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