Joining an OpenVMS Cluster

If you answered YES to the question about joining an OpenVMS Cluster, the system now asks a series of questions about your configuration (SCSI, local area, or mixed interconnect). If you answered NO to this question, the system immediately runs AUTOGEN, as described 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 the cluster configuration utility. You can do this by entering 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 the particular cluster configuration, some prompts are not displayed.

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 can 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.

Enter this cluster's group number¹:
Enter a number in the range of 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 can 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.

Enter a value for MYNODE's ALLOCLASS parameter.
In an OpenVMS Cluster environment, the allocation class value cannot be zero if the node serves disks to other cluster members or if the node will be using volume shadowing. In either case, the ALLOCLASS value must be a number from 1 to 255, and each node must have a unique ALLOCLASS value. For more information about setting ALLOCLASS for clusters, refer to the HP OpenVMS Cluster Systems manual.

Does this cluster contain a quorum disk (Y/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 Cluster group number and password are required by any cluster nodes that use the local area network. 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.
