Before You Begin
Ensure that the /etc/netmasks file has IP-address subnet and netmask entries for all logical hostnames. If necessary, edit the /etc/netmasks file to add any missing entries.
If you plan to install the Sybase ASE software at another location, omit this step.
For more information about installation locations, see Preparing to Install HA for Sybase ASE.
# clresourcegroup create [-n nodelist] resource-group
Specifies an optional, comma-separated list of node names or IDs that identify potential masters. The order here determines the order in which the Resource Groups Manager (RGM) considers primary nodes during failover.
Specifies the name of the resource group. This name can be your choice but must be unique for resource groups within the cluster.
# clreslogicalhostname create -g resource-group -h host_list logical_host
Specifies a resource name of your choice.
Specifies a comma-separated list of host names that are to be made available by the logical hostname resource.
Enabling the resource and fault monitoring
Moving the resource group into a managed state
Bringing the resource group online
# clresourcegroup online -M resource-group
The installation of the Sybase binaries must be performed on the node where the corresponding logical host is running.
Regardless of where you install the Sybase ASE software, modify each node's /etc/system files as you would in standard Sybase ASE installation procedures. For instructions about how to install the Sybase ASE software, refer to the Sybase installation and configuration guides.
If you do not specify a host name that is associated with a network resource, Sybase ASE starts only on the node where the Sybase ASE software was installed.
Some versions of Sybase ASE prompt you for the host name. Other versions of Sybase ASE use the physical host name. If your version of Sybase ASE uses the physical host name, you must change the physical host name to specify a network resource.
If the Sybase ASE installer prompts you for the host name, type the host name in response to the prompt.
Otherwise, modify the interfaces file to change the physical host name to a host name that is associated with a network resource.
