Installing the OpenVMS Operating System

Booting the New OpenVMS System Disk

Running AUTOGEN

Joining an OpenVMS Cluster

If during the installation, you previously answered YES to the question about joining an OpenVMS Cluster, the system now asks a series of questions about your configuration (CI, DSSI, SCSI, local area, or mixed-interconnect). If you answered NO to this question, the system immediately runs AUTOGEN, as explained in Running AUTOGEN. If you answered NO, you can still set up or join an OpenVMS Cluster after the installation is completed by manually running SYS$MANAGER:CLUSTER_CONFIG.COM. You can do this by executing the following command:

   $ @SYS$MANAGER:CLUSTER_CONFIG

For detailed information about cluster configuration, refer to the HP OpenVMS Cluster Systems manual or the Guidelines for OpenVMS Cluster Configurations manual.

Prompts for OpenVMS Cluster Configurations lists the OpenVMS Cluster prompts and suggested responses. These prompts appear if you answered YES to the question about joining an OpenVMS Cluster or if you manually run SYS$MANAGER:CLUSTER_CONFIG.COM. Note that, depending on your responses and particular cluster configuration, some prompts will not be displayed.

Table 3 Prompts for OpenVMS Cluster Configurations
Question How to Respond

Will this node be a cluster member (Y/N)?
Enter Y.

What is the node's DECnet node name?
Enter the DECnet node name (for example, MYNODE). The DECnet node name may be from one to six alphanumeric characters in length and cannot include dollar signs or underscores.

What is the node's DECnet node address?
Enter the DECnet node address --- for example, 2.2.

Will the Ethernet be used for cluster communications (Y/N)?
Enter N for a CI-only OpenVMS Cluster or DSSI-only OpenVMS Cluster. Otherwise, answer Y.¹

Enter this cluster's group number²:
Enter a number in the range from 1 to 4095 or 61440 to 65535.

Enter this cluster's password:
Enter the cluster password. The password must be from 1 to 31 alphanumeric characters in length and may include dollar signs and underscores.

Reenter this cluster's password for verification:
Reenter the password.

Will MYNODE be a disk server (Y/N)?
Enter Y if you want local disks to be served to the cluster (mandatory for local area and mixed-interconnect configurations). Refer to the HP OpenVMS Cluster Systems manual for information about served cluster disks.

Will MYNODE serve RFxx disks (Y)?
Enter a response appropriate for your DSSI configuration, if such disks are available.

Enter a value for MYNODE's ALLOCLASS parameter:
In a CI-only system (connected to a dual-ported disk), a DSSI-only system, or a local area or mixed-interconnect configuration where nodes serve DSSI or CI disks, enter the appropriate allocation class value (1 to 255). Otherwise, enter 0. For information about selecting the ALLOCLASS parameter, refer to the HP OpenVMS Cluster Systems manual.

Does this cluster contain a quorum disk (Y/N)?
For CI-only, SCSI, local area, and mixed-interconnect configurations, enter Y or N, depending on your configuration. For most DSSI systems, enter Y. However, if you are adding a two-system DSSI configuration to an existing cluster (in which case you might not need a quorum disk), you can answer N. If you enter Y, the system asks for the name of the quorum disk. Enter the device name of the quorum disk.

Refer to the HP OpenVMS Cluster Systems manual for information about quorum disks.

Footnotes

1 The Ethernet may not be required for communication within a local area OpenVMS Cluster system configured with FDDI devices. Within certain DSSI or CI (computer interconnect) mixed-interconnect configurations, neither the Ethernet nor FDDI may be required for communication. If your configuration fits either scenario, you can answer NO (N) to this prompt.

2 Cluster group number and password are not required if all the cluster nodes are directly connected; that is, the entire cluster uses interconnects such as CI, DSSI (Digital Storage Systems Interconnect), or MEMORY CHANNEL. In a cluster that uses mixed interconnects, if any of the interconnects require the cluster number and password, then you must set the cluster number and password for all nodes.
