The disk operation function, which functions only on the Windows system, enables disks to be
controlled and operated so as to operate the data replication and snapshot functions on the Windows
system.
Disk operation commands provide functions necessary for Windows disk operation linking with the
replication operation commands or snapshot operation commands rather than a function that replaces
Windows “Disk Management”. By using disk operation commands together with replication
operation commands or snapshot operation commands on the Windows system, you can easily conduct
operation that is comparable to the operation conducted on UNIX.

To carry out a file system flush, the iSMrc_flush command is used.
The iSMrc_flush command flushes the file system without unmounting the association of a drive letter
and volume, and writes the data in the file system buffer, which has not been reflected to the disk.
When you execute this command, you can reflect data to the disk without quitting the application.
This command executes Flush in units of volumes and flushes only Windows file systems so that other
volumes or applications handling their own cache control are not affected. To flush application data,
you also need to use the flush process specific to the application.
[Main Options]
For the iSMrc_flush command, the target volume is specified by its drive letter, mount point volume
name, or NTFS folder name.
[Displayed Information]
The iSMrc_flush command displays the following messages when Flush starts and ends.
[Start message]
Flush Start YYYY/MM/DD hh:mm:ss
disk_number ld_name type
volume_name
path
[End message]
Flush Normal End YYYY/MM/DD hh:mm:ss
disk_number ld_name type
