Source	Pause copyingIf you use the pause copying command, the volume condition	The mirror status will be changed to PAUSE and copying replication will be paused.
	Forceful sync	If you use the forceful sync command, the Resync	The mirror status will be changed to RESYNCING and the full synchronization will be done forcefullyinitiated between node.
	Resume copying	Continue to copy Resume MIRRORING the mirror volume that disk which was paused. Resynchronization will take place in advance, if there is data change during temporary pausepaused.
Target	Lock	Lock the The volume is locked to prevent access anymorethe volume from the node.
	Unlock	When you unlock Unlock the target volume , you can see the content of the file. to access read only purpose. Mirror status should be paused in advance.

Warning
When you unlock the target volume, you can see the content of the fileaccess the volume read only purpose. It can cause a negative effect to the mirror. Even if you unlock it, you cannot write to the filedisk. If you want to "write" to the filedisk, you must manually change the readOnly attributes in the registry. But it does not highly recommended to secure data integrity.

Attribute name	Description
JOB ID	JOB ID is displayed.
Bit Map	It is the directory containing the intent log.
Compression level	It represents the compression level for a specific copy set. The setting range is from 0 to 9. ‘0’ means no compression. The greater the value is, the smaller bandwidth is used to transmit greater data. But also, it uses more of the CPU resources. Thus, by properly balancing the system CPU usage and the network bandwidth, select the proper compression level that can maximize the efficiency.
Empty async queue	Even if a driver receives a request for deleting a queue, this function can be used to prevent deletion of queues on a specific volume.
Bandwidth	It is the max network bandwidth (kbps/sec) that can be used by a copy set. ‘0’ means that the given bandwidth will be used with maximum efficiency.
Mirror network address	Copy the volume to the set IP address of mirror disk between nodes in a cluster.
