Chapter 9: Configure PSFS Filesystems 98
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 HP CFS
Management Console or the mx assignpath command, the assignment
takes effect on all “UP” nodes in the cluster. 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 cluster.
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 HP CFS Management Console or the following mx fs commands:
assignpath/unassign/getdriveletters/queryassignments.
Filesystem Access
In the Windows operating system, a filesystem is automatically mounted
on a server the first time the server attempts to access it. When the server
is shut down, the filesystem is automatically unmounted. You do not
need to mount or unmount PSFS filesystems.
After a PSFS filesystem is created, it will appear on the HP Management
Console and can be accessed by the servers in the cluster. However, users
and applications on the servers will not be able to access the filesystem
until you assign a drive letter or mount point to it.
Managing assignments is key to controlling access to your filesystems.
Keep in mind the following:
• Filesystem mounts should not be confused with assignments.
Although a filesystem is mounted on multiple nodes, Windows
applications can access the mounted filesystem only via a drive
letter/mount point assignment.
