Before Beginning Installation; Using Multipath Software; Uninstalling And Reinstalling Microsoft Services For Nfs (Optional) - HP ProLiant DL380 G5 Administration Manual

Before beginning installation

Confirm that the following specifications have been met before proceeding:
• The HP ProLiant Storage Server SAN Connection and Management white paper (located on your
server documentation CD) must be completed and all the necessary software components for
connecting to the desired storage must be installed before the configuration of cluster services.
• It is required that at least one LUN has been presented for the configuration of the Quorum
disk. This LUN must be created from shared storage and must be at least 50 MB. (500 MB is
recommended). Additional LUNs may also be presented for use as shared disk resources.
• Cluster configurations should be deployed with dual data paths for high availability. Dual data
paths from each node enable a path failure to occur that does not force the failover of the node.
Clusters can be configured with single path, but if a failure in the path does occur, all of the node
resources will be failed to the non-affected node.

Using multipath software

Pathing software is required in configurations where multipathing to the storage is desired or required.
For clustered products, HP recommends maintaining two paths to the data as pathing software allows for
datapath failure to occur without forcing a node failover. Refer to the HP ProLiant Storage Server SAN
Connection and Management white paper (located on your server documentation CD) for additional
information on multipath software.

Uninstalling and reinstalling 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. 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.
