HP StorageWorks Clustered File System 3.6.0 Windows Storage Server Edition Administration Guide (403103-005, January 2008)

Chapter 9: Configure PSFS Filesystems 97
The Windows operating system and Windows Disk Management utilities
are not fully aware of PSFS filesystems or HP Clustered File System
dynamic volumes. Although these Microsoft utilities can be useful for
troubleshooting issues, they cannot display status from the perspective of
an HP Clustered File System volume or filesystem.
Dynamic Volumes
Dynamic volumes created with the HP Clustered File System Volume
Manager are not the same as Microsoft dynamic volumes. HP Clustered
File System cannot use Microsoft dynamic volumes, and vice versa.
(Although it is possible to format an HP Clustered File System dynamic
volume with FAT or NTFS, it is not recommended because FAT and NTFS
are not cluster filesystems; data corruption will result if more than one
server at a time has local access to the same FAT or NTFS filesystem, a
problem that the PSFS filesystem was specifically designed to solve).
The HP Management Console includes a Volume Properties window
(select Storage > Dynamic Volume > Volume Properties) that displays
status information for 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 an HP Clustered File
System 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 HP Clustered File System uses internally for both psd and psv
devices. (The HP Management Console and mx commands hide these
mount points.) We recommend 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.
