Before beginnin
g installation
Confirm that the
following specifications have been m et before proceeding:
• The HP ProLiant Storage Server SAN Connection a nd 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 b e presented for use as shared disk resources.
• Cluster configurations should be deployed with dual data paths for high availability. Dual data
pathsfromeachnodeenableapathfailuretooccurthatdoesnotforcethefailoverofthenode.
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 soft ware 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
informationonmultipathsoftware.
Uninstalling and reinstalling Microsoft Services for NFS (optional)
The server comes with Microsoft Services for N etwork File System (NFS) preinstalled. Microsoft has
identifi
ed an issue that requires that NFS be uninstalled prior to installing clustering on the storage server.
This on
ly applies if you want NFS share resources on the storage server within the clustering environment.
After c
lustering 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 Pan el > Add or Remove Programs.TheAddorRemovePrograms
window is displayed.
2. Ontheleftsideofthewindow,selectAdd/Remove Windows Compone nts. The Windows
Components Wizard appears.
