Dell 38XX, 34XX, 32XX Enabled Automatic resynchronization is, Disabled Automatic resynchronization

Parameter	Description
	secondary virtual disks of a remote-replicated pair.
	This parameter has these values:
	• enabled – Automatic resynchronization is
	turned on. You do not need to do anything
	further to resynchronize the primary virtual
	disk and the secondary virtual disk.
	• disabled – Automatic resynchronization
	is turned off. To resynchronize the primary
	virtual disks and the secondary virtual disk, you
	must run the resume remoteReplication
	command.
writeOrder	This parameter defines write order for data
	transmission between the primary virtual disk and
	the secondary virtual disk. Valid values are
	preserved or notPreserved.
writeMode	This parameter defines how the primary virtual disk
	writes to the secondary virtual disk. Valid values are
	synchronous or asynchronous.
force	The role reversal is forced if the communications
	link between the storage arrays is down and
	promotion or demotion on the local side results in
	a dual-primary condition or a dual-secondary
	condition. To force a role reversal, set this
	parameter to TRUE. The default value is FALSE.
	NOTE: Use the force parameter only when
	using the role parameter.

Notes

When you use this command, you can specify one or more optional parameters.

Synchronization priority defines the amount of system resources that are used to synchronize the data between the primary virtual disks and the secondary virtual disks of a replication relationship. If you select the highest priority level, the data synchronization uses the most system resources to perform the full synchronization, which decreases the performance for host data transfers.

The writeOrder parameter applies only to asynchronous write modes and makes them become part of a consistency group. Setting the writeOrder parameter to preserved causes the remote-replicated pair to transmit data from the primary virtual disk to the secondary virtual disk in the same order as the host writes to the primary virtual disk. In the event of a transmission link failure, the data is buffered until a full synchronization can occur. This action can require additional system overhead to maintain the buffered data, which slows operations. Setting the writeOrder parameter to notPreserved frees the system from having to maintain data in a buffer, but it requires forcing a full synchronization to make sure that the secondary virtual disk has the same data as the primary virtual disk.
