dynamic volumes and the filesystems created on those volumes. You can also view
this information with the mx dynvolume command.
The Windows Disk Manager utilities cannot display a Matrix Server dynamic volume
with its associated psv name and volume information. Instead, the Disk Manager
displays the local disk information for each subdevice included in the dynamic volume,
with drive letter and/or mount point assignments shown on the first subdevice of the
dynamic volume.
Reserved mount point assignments
The Microsoft utilities also show the reserved mount point assignments that Matrix
Server uses internally for both psd and psv devices. (The PolyServe Management
Console and mx commands hide these mount points.) HP recommends that you do
not use the reserved mount points and instead define your own drive letters and/or
mount points for access to your PSFS filesystems.
NOTE:
Be careful not to accidentally back up PSFS filesystems multiple times by using both
your site-defined drive letter/mount point assignments and the reserved mount points.
Filter out the reserved mount points from backup jobs, and instead use your own
site-defined assignments.
PSFS filesystems
When you assign a drive letter or mount point via the PolyServe Management Console
or the mx assignpath command, the assignment takes effect on all “UP” nodes
in the matrix. If a node is down or you add a new node later on, you will need to
establish the correct assignments on the node when it joins the matrix.
Although drive letters or mount points can be assigned from the Windows Disk
Management utilities, the assignment takes effect on only the node from which the
operation is run. You will then need to repeat the assignment on each additional
node. To manage assignments on all “UP” nodes in one easy step instead of
separately managing each node, use the PolyServe Management Console or the
following mx fs commands:
