create cluster

Creates an SAP ASE shared-disk cluster.

Enter the necessary configuration information interactively, as responses to a series of prompts, or use an input file.

Syntax

create cluster [cluster_name ]
	[ login login_name ]
	[ password password ]
	[ agent “agent_spec[, agent_spec[, ...]]” ]
	[ discovery “ discovery_spec[, discovery_spec[, ...]]” ]
	[ file “input_file” ]

Parameters

cluster_name – is the name of the cluster.
login login_name – is the management agent login for the Sybase Common Security Infrastructure in the Unified Agent framework. The default user name after installation is “uafadmin” with no password; this is the simple login module in the agent configuration. You can configure the user name and password to use several different mechanisms for authentication and authorization, including operating system logins.
password password – is the management agent password for the Sybase Common Security Infrastructure in the Unified Agent framework. The default user name after installation is “uafadmin” with no password; this is the Simple Login Module in the Agent configuration. You can configure the user name and password to use several different mechanisms for authentication and authorization, including operating system logins.
agent agent_spec – is the agent specification that identifies the nodes in the cluster running a Unified Agent, and the port number that sybcluster uses to connect to the Unified Agent.
The format is node_name:port_number [, node_name:port_number ] [,...]. The default port number is “9999.”
discovery discovery_spec – is the discovery method used to identify the agents responsible for the requested cluster.
The format is method[(method_specification)] [, (method_specification)[,...]]. See the description for sybcluster -d discovery_list.
file “input_file” – is the operating system input file for creating the cluster.

Examples

Create a cluster with sybcluter prompts – Creates a new cluster called “mycluster”; sybcluster prompts you for the information necessary to create the cluster:
```
create cluster mycluster
```
Create a cluster using a configuration file – Creates a new cluster called “mycluster1” using configuration information supplied in the mycluster1.xml file:
```
create cluster mycluster1 file mycluster1.xml
```

Usage

When you create a cluster, sybcluster prompts for:

Cluster name, if one has not been provided.
Number of instances.
Installation mode for the cluster (private or shared).
Complete path to the master, quorum, PCI, systemdb, sybsysprocs, and temporary database devices.
Path to the interfaces file, if LDAP is not configured and this is a shared install.
(Optional) Trace flags.
Complete path to the dataserver configuration file, if this is a shared install.
Primary and secondary interconnection protocols.
Instance host name, port number, private address, log file location, and start-up arguments.

If this is a private installation, sybcluster also prompts for the $SYBASE installation directory, SAP ASE home directory, dataserver configuration file location, and interfaces file location (if LDAP is not configured).

If sybcluster detects the Veritas Cluster Server (VCS) on the system, sybcluster asks if it should check whether device is managed by VCS.

After you create and confirm the cluster, create cluster prompts for an I/O fencing check, which checks whether or not each device has I/O fencing capability (see the Installation Guide for a description of I/O fencing).
