change disk slowthreshold

change disk slowthreshold

Function

The change disk slowthreshold command is used to set the parameter of the slow disk period.

Format

change disk slowthreshold model=? [ threshold=? ] [ cycle_time=? ] [ cycle_total=? ] [ cycle_threshold=? ]

Parameters

Parameter

Description

Value

model=?

Way to set the threshold of the slow disk period.

Possible values are SYS_AUTO_MODEL and CUSTOMER_SET_MODEL, where:

  • "SYS_AUTO_MODEL": The slow-disk threshold mode is automatically set based on the configuration file.
  • "CUSTOMER_SET_MODEL": The slow-disk threshold mode must be manually set.

threshold=?

Threshold of the slow disk period.

  • The value contains five decreasing integers, which are separated by commas (,).
  • Each integer ranges from 1 to 65,534, expressed in milliseconds.

Example: 300,250,200,150,100.

cycle_time=?

Period duration.

The value ranges from 1 to 30, expressed in seconds.

cycle_total=?

Total number of periods.

The value ranges from 10 to 100.

cycle_threshold =?

Threshold of the slow disk period number.

The value ranges from 1 to 100.

Example

  • Enable the system to obtain the threshold of the slow disk period from the configuration file.
    developer:/>change disk slowthreshold model=SYS_AUTO_MODEL 
    DANGER: You are about to change the threshold of the slow disk period. This operation may cause system abnormalities. 
    Suggestion: Note the following before and after the command execution: 
    1. Ensure that the command is to be executed by the R&D personnel. 
    2. The command will change the threshold of the slow disk period. The system may report slow disks. 
    3. After executing this command, check whether the service system is running correctly. 
    Have you read danger alert message carefully?(y/n)y 
    Are you sure you really want to perform the operation?(y/n)y 
    Command executed successfully.
  • Set the threshold of the slow disk period to "300,250,200,150,100" milliseconds.
    developer:/>change disk slowthreshold model=CUSTOMER_SET_MODEL threshold=300,250,200,150,100 cycle_time=3 cycle_total=100 cycle_threshold=50 
    DANGER: You are about to change the threshold of the slow disk period. This operation may cause system abnormalities.
