Dell PowerFlex Manager 4.6.x CLI Reference Guide

A volume can be a member of at most one replication pair. When the replication pair is created, both the source volume and the target volume must be the same size. It is recommended, but not mandatory, that the volumes in the volume pair have the same attributes (including zero padding and granularity). Not doing so can impact performance and capacity.

Syntax

Syntax for adding pair without destination volume auto-provisioning (destination volume must be pre-created):

scli --add_replication_pair (--replication_consistency_group_id <ID> | --
replication_consistency_group_name <NAME>) (--source_volume_id <ID> | --
source_volume_name <NAME>) (--destination_volume_id <ID> | --destination_volume_name
<NAME>) [--replication_pair_name <NAME>]

Syntax for adding pair with destination volume auto-provisioning:

scli --add_replication_pair  [--replication_pair_name <NAME>]
(--replication_consistency_group_id <ID> | --replication_consistency_group_name <NAME>) (--source_volume_id <ID> | --source_volume_name <NAME>) (--destination_storage_pool_name <NAME> | --destination_storage_pool_id <ID>) [--destination_sdc_id <ID> | --destination_sdc_name <NAME> | --destination_sdc_guid <GUID> | --destination_sdc_ip <IP>]  [--compression_method <METHOD>] [Provisioning options] [Use RAM Read Cache options]  [--access_mode <ACCESS_MODE>] [--allow_multi_map]

Parameters

--replication_pair_name <NAME>

Replication pair name

--replication_consistency_group_id <ID>

Replication consistency group ID

--replication_consistency_group_name <NAME>

Replication consistency group name

--source_volume_id <ID>

Source volume ID

--source_volume_name <NAME>

Source volume name

--destination_sdc_ip <IP>

Destination SDC IP

Provisioning options:

If auto provision option is selected, provide the following:

Compression (optional):

--compression_method <METHOD>

Indicates the compression method to be used, relevant only for fine granularity data layouts.

none— No compression applied

normal—Normal compression applied

Destination storage pool option: Select any one of the following:

--destination_storage_pool_name <NAME>

Destination storage pool name

--destination_storage_pool_id <ID>

Destination storage pool ID

Provisioning options: Select any one of the following:

--thin_provisioned

This volume will be thin-provisioned

--thick_provisioned

This volume will be thick-provisioned

<BLANK>

Use storage pool default (thick for medium granularity, thin for fine granularity)

Use RAM read cache: Select any one of the following:

--use_rmcache

The specified volume uses caching

--dont_use_rmcache

The specified volume does not use caching

<BLANK>

Use storage pool default value

Indicates what dst (destination) SDC exposes the dst volume in case of disaster recovery:

--destination_sdc_id <ID>

SDC ID

--destination_sdc_name <NAME>

SDC name

--destination_sdc_guid <GUID>

SDC global unique identifier

--destination_sdc_ip <IP>

SDC IP address

Destination volume mapping to SDC (optional):

--access_mode <ACCESS_MODE>

Mapping access mode when not in disaster recovery. Can be one of the following: no_access (default), read_only

--allow_multi_map

Allow this volume to be mapped to more than one SDC
