Become superuser on a cluster member.
If you plan to install the Sybase ASE software on the cluster file system, start the Sun Cluster software and become the owner of the disk device group.
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 Sun Cluster HA for Sybase ASE.
Create a failover resource group to hold the network and application resources.
# scrgadm -a -g resource-group [-h nodelist]
Specifies the name of the resource group. This name can be your choice but must be unique for resource groups within the cluster.
Specifies an optional, comma-separated list of physical node names or IDs that identify potential masters. The order here determines the order in which the Resource Group Manager (RGM) considers primary nodes during failover.
Use the -h option to specify the order of the node list. If all of the nodes in the cluster are potential masters, you do not need to use the -h option.
Verify that you have added all of the network resources that Sun Cluster HA for Sybase ASE uses to either the /etc/inet/hosts file or to your name service (NIS, NIS+) database.
Add a network resource (logical host name or shared address) to the failover resource group.
# scrgadm -a -L -g resource-group -l logical-hostname [-n netiflist]
Specifies a network resource. The network resource is the logical host name or shared address (IP address) that clients use to access Sun Cluster HA for Sybase ASE.
Specifies an optional, comma-separated list that identifies the IP Networking Multipathing groups that are on each node. Each element in netiflist must be in the form of netif@node. netif can be given as an IP Networking Multipathing group name, such as sc_ipmp0. The node can be identified by the node name or node ID, such as sc_ipmp0@1 or sc_ipmp@phys-schost-1.
Sun Cluster does not support the use of the adapter name for netif.
Run the scswitch(1M) command to complete the following tasks.
Enabling the resource and fault monitoring
Moving the resource group into a managed state
Bringing the resource group online
# scswitch -Z -g resource-group
On the node that masters the resource group that you just created, log in as sybase.
The installation of the Sybase binaries must be performed on the node where the corresponding logical host is running.
Install the Sybase ASE software.
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.
For every Sybase ASE server, specify the host name that is associated with a network resource.
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, such as 12.5, prompt you for the host name. Other versions of Sybase ASE, such as 12.5.1, 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.
After you install the Sybase ASE software, go to How to Verify the Sybase ASE Installation.
