, so choose the highest performance workstation available. Software Requirements You must have the NetWare 5 Support Pack 3 or later running on each cluster server. You can install Support Pack 3 for NetWare 5.0 from the NetWare Cluster Services product CD. Ensure the following requirements are met - HP LH4r | Novell NetWare Cluster Services for NetWare 5 Installation guide - Page 14
instructions. Prior to installation, verify that all the drives in your shared disk system are recognized by NetWare by running the List Devices command on each server 5, a single device error can cause a system failure. NetWare Cluster Services software will not protect against such faults. - HP LH4r | Novell NetWare Cluster Services for NetWare 5 Installation guide - Page 15
Agreement (MLA). Changes to NetWare 5 non-MLA licensing include: • The server base licenses for each cluster server are deleted and are replaced with a server base license upgrade. This server base license upgrade works specifically with NetWare Cluster Services.
