The Sybase installation directory can be located on a local disk or a shared storage.
Review the following prerequisites:
If the Sybase binaries are installed on a local disk, verify that the installation path is same on all the nodes in the cluster. Make sure the Sybase configuration files are identical on all the nodes in the cluster.
If the Sybase binaries are installed on shared disks, make sure the mount points for the shared disks are same on all the nodes. The Sybase installation directory is specified by the environment variable $SYBASE. Create the same $SYBASE mount points on each system.
