Using multipath data paths for high availability – HP ProLiant DL380 G5-Storage-Server User Manual
Page 108
Using multipath data paths for high availability
HP recommends that cluster configurations be deployed with dual data paths for high
availability. Clusters can be configured with single path, but if a failure in the path occurs, all
of the node resources will be failed to the non-affected node. Pathing software is required in
configurations where multipathing to the storage is desired or required. Multipathing software
allows for datapath failure to occur without forcing a node failover. See the HP ProLiant
Storage Server SAN Connection and Management white paper (located on the HP web site at
for
additional information on multipath software.
Enabling cluster aware Microsoft Services for NFS (optional)
The server comes with Microsoft Services for Network File System (NFS) preinstalled. Microsoft has
identified an issue that requires that NFS be uninstalled prior to installing clustering on the storage server.
This only applies if you want NFS share resources on the storage server within the clustering environment.
After clustering is installed, then NFS can be installed if you desire this feature.
NOTE:
Failure to uninstall Microsoft NFS prior to the installation of clustering results in no NFS resource types
being available in the clustering environment.
To uninstall Microsoft NFS:
1.
From the storage server desktop, select Start > Settings > Control Panel > Add or Remove Programs.
The Add or Remove Programs window is displayed.
2.
On the left side of the window, select Add/Remove Windows Components. The Windows
Components Wizard appears.
3.
Select Other Network File and Print Services and click the Details button. The Other Network
File and Print Services window is displayed.
4.
Uncheck the Microsoft Services for NFS subcomponent.
5.
Click OK, then Next, followed by Finish.
NOTE:
Uninstalling Microsoft Services for NFS removes two primary services:
•
Server for NFS
•
User Name Mapping
After setting up clustering, should you choose to reinstall Microsoft NFS, follow these steps:
1.
Select Start > Settings > Control Panel > Add or Remove Programs. The Add or Remove Programs
window is displayed.
2.
On the left side of the window, select Add/Remove Windows Components. The Windows
Components Wizard appears.
3.
Select Other Network File and Print Services and click the Details button. The Other Network
File and Print Services window is displayed.
4.
Check the Microsoft Services for NFS subcomponent.
5.
Click OK, then Next, followed by Finish.
6.
After NFS is installed, you can view the details of the Microsoft Services for NFS subcomponent to
see which of its subcomponents were installed. The subcomponents listed below are preinstalled at
the factory. Verify that the Server for NFS and User Name Mapping services have been reinstalled.
