change remote_replication general

change remote_replication general

Function

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

Format

change remote_replication general remote_replication_id=? { compress_enable=? | recovery_policy=? | synchronization_rate=? | synchronization_type=? | timing_length=? timing_unit=? | second_res_access=? } *

Parameters

Parameter

Description

Value

remote_replication_id=? Remote replication ID.

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

recovery_policy=? Recovery policy.

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

  • "automatic": When interrupted links are recovered, remote replication is automatically resumed. Data is automatically synchronized from the primary LUN to the secondary LUN.
  • "manual": When interrupted links are recovered, remote replication needs to be resumed manually. The secondary LUN retains the state preserved at the time when links are interrupted. Data is not automatically synchronized from the primary LUN to the secondary LUN.
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", 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.
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.
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 ranges from 1 to 1440, expressed in minutes.
  • The value ranges from 3 to 59, expressed in seconds.
timing_unit=? Unit of the synchronization period.

The value can be:

  • "minute": indicates minutes.
  • "second": indicates seconds.
second_res_access=? Read and write attributes of the secondary LUN.

The value can be "read_only" or "read_write", where:

  • "read_only": The secondary LUN can only be read.
  • "read_write": The secondary LUN can be read and written.
compress_enable=? Whether to enable compress.

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