Operating system related commands
FlushCache
command
Syntax
FlushCache -VirtualDisk MountedVirtualDiskOrSnapshotName
Description
Flushes the memory cache of the operating system associated with a VSM virtual disk or snapshot
mounted on the computer.
IMPORTANT:
This command is only valid for Windows 2003/2008. For other operating systems, a device dismount
will also force the cache flush.
MountVirtualDisk
command
Syntax
MountVirtualDisk -MountPoint H:\, -VirtualDisk VirtualDiskName ~
[, -Partition Partition] [, -Override]
Description
Mounts a virtual disk or snapshot. The virtual disk or snapshot must have at least one file system
(partition) on it.
The following are rules for the Windows operating system:
• The mount point must always end with a backslash (for example, Q:\ or H:\MP\).
• If the mount point is a drive letter, it must be a free drive letter (or use the -Override argument).
• If the mount point points to a folder, the target folder must be empty or nonexistent, and it must
be an NTFS file system.
The -Partition argument is optional, and has the following guidelines:
• If using the -Partition argument in Windows, the specific partition is mounted as a partition
number (as a string).
• If using the -Partition argument in UNIX, the specific partition is mounted as a logical virtual
disk name.
