Issue Description
What is the aggregation interruption function used for? When should this function be enabled?

Solution
The aggregation interruption function is used to improve the storage system performance under heavy concurrent access pressure.

On the CLI, run the showserviecfg command to view the status of the aggregation interruption function. In the command result, if the value of fc tgt interrupt is 1, the aggregation interruption function is enabled, and if the value is 0, the function is disabled. You can set the aggregation interruption function by either of the following two methods:
  • On the CLI, run the setservicefg-i 3 -v 1/0 command to set the aggregation interruption function in offline mode. When the value of -v is set to 1, the function is enabled. When the value is set to 0, the function is disabled.
  • On the CLI, run the setservicefg-i 3 -v 1/0 -f command to forcibly set the aggregation interruption function in online mode. When the value of -v is set to 1, the function is enabled. When the value is set to 0, the function is disabled. The system prompts a warning after a value is entered.
NOTICE:
     Forcibly setting the aggregation interruption function in online mode is a risky operation, and it may cause system anomalies if I/Os are being processed. Do this operation under the guidance of R&D personnel and when no I/O is being processed.
