change remote_replication file_system

change remote_replication file_system

Function

The change remote_replication file_system command is used to modify the settings of a specified file system remote replication.

Format

change remote_replication file_system remote_replication_id=? { compress_enable=? | recovery_policy=? | synchronization_rate=? | synchronization_type=? [ schedule_rule=? time_of_week=? time_of_day=? time_of_hour=? | timing_length=? timing_unit=? ] } *

Parameters

Parameter

Description

Value

remote_replication_id=? Remote replication ID.

To obtain the value, run "show remote_replication unified".

recovery_policy=? Recovery policy.

The value can be "automatic" or "manual", where:

  • "automatic": When links are recovered, the remote replication is automatically resumed. Data is automatically synchronized from the primary file system to the secondary file system.
  • "manual": When links are recovered, the remote replication needs to be resumed manually. The secondary file system retains the state preserved at the time when links are interrupted. Data is not automatically synchronized from the primary file system to the secondary file system.
compress_enable=? Whether to enable compress.

The value can be "yes" or "no", where: 1:yes:enable compress. 2:no:disable compress.

synchronization_type=? Synchronization type. This parameter is available only for asynchronous remote replication.

The value can be "manual", "timed_wait_when_synchronization_begins", "timed_wait_when_synchronization_ends", or "auto", where:

  • "manual": Data needs to be synchronized manually.
  • "timed_wait_when_synchronization_begins": The system starts timing as soon as data synchronization starts.
  • "timed_wait_when_synchronization_ends": The system starts timing as soon as data synchronization ends.
  • "auto": The system determines data synchronization.
synchronization_rate=? Synchronization rate.

The value can be "Low", "Middle", "High", or "Highest", where:

  • "Low": indicates the low rate.
  • "Middle": indicates the medium rate.
  • "High": indicates the high rate.
  • "Highest": indicates the highest rate.
schedule_rule=? Specify the time policy.

The value can be "hourly", "daily", or "weekly", where:

  • "hourly":Specifies when data synchronization begins in every hour.
  • "daily":Specifies when data synchronization begins in every day.
  • "weekly":Specifies when data synchronization begins in every week.
time_of_week=? Synchronization on sometimes of every week.

The value ranges from Monday to Sunday and 00:00 to 23:59.

time_of_day=? Synchronization on sometimes of every day.

The value ranges from 00:00 to 23:59.

time_of_hour=? Synchronization on sometimes of every hour.

The value is an integer ranging from 0 to 59.

timing_length=? Timing period (data synchronization period). This parameter is available only when synchronization_type=? is set to "timed_wait_when_synchronization_begins" or "timed_wait_when_synchronization_ends".

The value is an integer ranging from 5 to 1440, expressed in minutes.

timing_unit=? Unit of the synchronization period.

The value is "minute".

Level

Administrator

Usage Guidelines

This command does not support 2200 V3 storage system.
