4.0.0 HP Polyserve Matrix Server Administration Guide (T5392-96052, March 2010)

Assign Drive Letter: Matrix Server queries the servers in the matrix to determine the
drive letters that are currently unused on all of the servers. You can assign any of
these drive letters to the filesystem.
NOTE:
If, on a matrix server, the drive letter you selected is assigned for another purpose
before the Assign Drive Letter operation is complete, the affected server will not be
able to access the filesystem via the drive letter. You can remove drive letters and
reassign them as necessary to ensure that all servers can access the filesystem.
Specify Mount Path: Mount paths are also known as NTFS junctions, and allow you
to mount another volume in an empty directory on an NTFS volume. Enter the complete
pathname (for example, C:\data1). Matrix Server can create the mount path if it
does not already exist on each server that will mount the filesystem. If necessary,
check Create the directory if it does not exist.
You can specify both a drive letter and a mount path for a filesystem; however, you
will need to do this in separate operations.
You can also assign a drive letter or path from the command line:
mx fs assignpath --path x fs assignpath --path <path or driveletter>
[--createdir] <filesystem> <ALL_SERVERS | server ...>
The --createdir option creates the mount path if it does not already exist on each
server.
If a server was out of the matrix while the drive assignment was made or you add a
new server to the matrix, you can use the above command to add the drive assignment
to that server.
