change hyper_metro_consistency_group general

change hyper_metro_consistency_group general

Function

The change hyper_metro_consistency_group general command is used to change the information about a HyperMetro consistency group.

Format

change hyper_metro_consistency_group general consistency_group_id=? { synchronization_rate=? | name=? | recovery_policy=? | description=? | isolation_switch=? | isolation_threshold=? } *

Parameters

Parameter

Description

Value

consistency_group_id=?

ID of the HyperMetro consistency group.

Run the "show hyper_metro_consistency_group general" command without parameters to obtain the value.

synchronization_rate=?

Synchronization rate.

The value is "Low", "Middle", "High", or "Highest", where:

  • "Low": low rate.
  • "Middle": medium rate.
  • "High": high rate.
  • "Highest": the highest rate.

name=?

Name of the consistency group.

The value contains 1 to 31 ASCII characters including digits, letters, underscores (_), hyphens (-), and periods (.), and can only start with a digit or a letter.

recovery_policy=?

Recovery policy.

The value is "automatic" or "manual", where:

  • "automatic":automatic recovery policy. Data will be automatically synchronized after faults are rectified.
  • "manual": manual recovery policy. Data needs to be manually synchronized after faults are rectified.

description=?

Description of the HyperMetro consistency group.

The value contains 1 to 127 letters.

isolation_switch=?

Isolation switch.

The value is "open" or "close", where:

  • "open":turns on the isolation switch. After the isolation switch is turned on, the system will suspend the HyperMetro pair in the consistency group if the difference between the write I/O latency of the two storage arrays is greater than the "isolation threshold". The storage array with the longer write I/O latency will stop providing services.
  • "close":turns off the isolation switch.

isolation_threshold=?

Isolation threshold.

The value ranges from 10ms to 30s.The default value is "1s".

Level

Administrator

Usage Guidelines

None

Example

  • Change the synchronization rate of HyperMetro consistency group 1 to "Low".
    admin:/>change hyper_metro_consistency_group general consistency_group_id=1 synchronization_rate=Low 
    Command executed successfully.
  • Change the synchronization rate of HyperMetro consistency group 1 to "Highest".
    admin:/>change hyper_metro_consistency_group general consistency_group_id=1 synchronization_rate=Highest 
    WARNING: You are about to change the synchronization speed to the "Highest". 
    After the operation, the Hyper Metro pair will be synchronized at the highest speed, which may cause host latency increase and disconnection of HyperMetro pairs. 
    Suggestion: Select a low synchronization speed or use the "Highest" synchronization speed during off-peak hours. 
    Have you read warning message carefully?(y/n)y 
    Are you sure you really want to perform the operation?(y/n)y 
    Command executed successfully.
