shared Instructs driver to open image file in shared write mode even when
image is opened for writing. This can be useful to mount each partition
of a multi-partition image as separate virtual disks with different
image file offsets and sizes. It could potentially corrupt filesystems
if used with incorrect offset and size parameters so use with caution!
par Parallel I/. Valid for file-type virtual disks. With this flag set,
driver sends read and write requests for the virtual disk directly down
to the filesystem driver that handles the image file, within the same
thread context as the original request was made. In some scenarios this
flag can increase performance, particularly when you use several layers
of virtual disks backed by image files stored on other virtual disks,
network file shares or similar storage.
This flag is not supported in all scenarios depending on other drivers
that need to complete requests to the image file. It could also degrade
performance or cause reads and writes to fail if underlying drivers
cannot handle/0 requests simultaneously.
-u unit
Along with -a, request a specific unit number for the ImDisk device
instead of automatic allocation Along with -d or -1 specifies the
unit number of the virtual disk to remove or query.
-m mountpoint
Specifies a drive letter or mount point for the new virtual disk, the
virtual disk to query or the virtual disk to remove. When creating a
new virtual disk you can specify#: as mountpoint in which case the
first unused drive letter is automatically used.
Persistent. Along with -a, saves registry settings for re-creating the
same virtual disk automatically when driver is loaded, which usually
occurs during system startup. Along with -d or -D, existing such
settings for the removed virtual disk are also removed from registry.
There are some limitations to what settings could be saved in this way.
Only features directly implemented in the kernel level driver are
saved, so for example the -p switch to format a virtual disk will not
be saved. |
