Step 5. Terminating applications (business server)
To maintain data consistency, terminate or halt applications that are accessing the volume concerned.
If application has not been terminated, unmounting in step 7 fails.
If shared folders are used on the volume concerned, cancel sharing temporarily.
(Example) Stopping service
NET STOP (service name)
To stop the service “ESMCommonService”, specify as shown below.
NET STOP ESMCommonService
(Example) Canceling shared folder
NET SHARE shared name/delete
To cancel the sharing of the folder mv_folder1, specify as shown below.
NET SHARE mv_folder1 /delete
Step 6. Flushing MV file system (business server)
Flush the MV file system and write the file system buffer data, not yet written, to the disk.
iSMrc_flush -drv G:
Then, the following message appears and flushing is executed.
Flush Start 2001/02/21 12:23:14
disk10 dev001 WN
\\?\Volume{822575dd-63d9-11d5-b1e0-009027520bce}\
G:
Flush Normal End 2001/02/21 12:23:14
disk10 dev001 WN
\\?\Volume{822575dd-63d9-11d5-b1e0-009027520bce}\

Step 7. Unmounting MV (business server)
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 between MV and RV.
To keep data consistency between MV and RV, unmount MV after terminating applications, and cancel
association between the volume and file system.
To execute unmount, you must terminate 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.
