You can determine what \\?\Volume{guid}\ is configured, as follows:

inqraid $Volume{bf48a395-0ef6-11d5-8d69-00c00d003b1e} -CLI
DEVICE_FILE PORT SERIAL LDEV CTG H/M/12 SSID R:Group PRODUCT_ID

raidscan -pi $Volume

System buffer flushing function

The logical drive to be flushed can be specified by the following two methods. One method is that
the logical drive (for example, G:\hd1 drive, as below) is specified immediately, but this method
must know about the logical drive corresponding to a group before executing the sync command.
Also the volume is mounting by a directory and this method requires finding its volume name. To
solve such a complication, RAID Manager supports a method that flushes the system buffer associated
with a logical drive through finding a volume{guid} corresponding to a group of the configuration
file. This method does not depend on mounted point, so that it is possible to flush the volume
mounted by a directory. This method is supported to be specified a group to the raidscan -find
sync

command.

The following example flushes the system buffer associated with the ORB group through $Volume.

raidscan -pi

$Volume -find sync -g ORB

[SYNC] : ORB ORB_000[-] -> \Dmt1\Dsk1 : Volume{bf48a395-0ef6-11d5
8d69-00c00d003b1e}
[SYNC] : ORB ORB_001[-] -> \Dmt1\Dsk2 : Volume{bf48a395-0ef6-11d5
8d69-00c00d003b1e}
[SYNC] : ORB ORB_002[-] -> \Dmt1\Dsk3 : Volume{bf48a395-0ef6-11d5
8d69-00c00d003b1e}

The following example flushes the system buffer associated with all groups for the local instance.
