Critical

Impact on the System

  • The controller power-on times out. System reliability decreases.
  • With the write protection function being enabled (by default) when an engine works with a single controller, if the controller that fails to be initiated cannot return to normal within the specified period, the write function of services on the engine where the faulty node resides is disabled and the read/write performance is reduced.

Possible Causes

The controller has internal errors.

Procedure

  1. Collect the log information and contact technical support engineers to rectify the fault. If the fault cannot be rectified immediately=> Step2.
  2. The write policy of the system will become write through after a while, decreasing read/write performance. If you want to restore system performance, enter the developer view of the CLI and run the "change system write_through_policy write_through_switch=Disable" command to disable write through of the controller. However, if the controller malfunctions after the function is disabled, data may be lost, affecting system reliability.
