Chapter 2    Operation and Maintenance 

 

You must create a perfect static point of MV data. 

This is for writing the metadata of the file system completely to the disk.    This is also for suppressing 

I/O to the logical volume to keep data consistency of MV and RV. 

To keep data consistency of MV and RV, unmount MV after stopping operation, and cancel association 

between the volume and file system. 

To execute unmount, you must quit all application software which access the drive.    Also refer to the 

description about unmount in Chapter 3 “Notes”. 

If MV unmounting failed and no means of avoidance exists, wait for 60 seconds and proceed to step 8. 

In addition, although separating is allowed without unmounting in this step, unmounting upon 

replication and restoration is mandatory.

Then, the following message is displayed and MV is unmounted.

Execute Separate to separate MV and RV to make RV available, and resume applications. 

This example uses the replication file and separates MV and RV according to the following settings. 

•  Copy range: Difference (default value) 
•  Update reflection to RV: Sync mode (default value) 
•  Access restrictions for RV after Separate: rw (Read/Write) (default value) 
•  Specify the wait for Separate completion
