Linux7 hardware time occasionally encounter nonsense Powerpath startup error

New environment, RHEL 7.2 installs EMPPP multipath software
But after starting, an ERROR
, Nov 14 10:44:46 localhost PowerPathPost: ERROR: Cannot open PowerPath. Initialization ERROR
, Nov 14 10:44:46 localhost PowerPathPost: ERROR: Cannot open PowerPath
Later, I checked EMC’s official website and found relevant bugs, because the hardware time and system time did not match. When the PP starts, it needs to be initialized. Hwoo-w synchronization time, and restart the host after normal.
