HP OpenVMS 8.x Joining an OpenVMS Cluster, You can do this by entering the following command

now, as explained in Section A.5 (page 164). Appendix A (page 149) includes additional information regarding setting up and booting HP Integrity servers.

3.5 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 (such as CI, DSSI, SCSI, local area, or mixed interconnect). If you answered NO to this question, the system immediately runs AUTOGEN, as described in Section 3.6 (page 75). 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_LAN

For more information about cluster configuration, see the HP OpenVMS Cluster Systems manual or the Guidelines for OpenVMS Cluster Configurations manual.

Table 3-2lists 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_LAN.COM. Note that, depending on your responses and the particular cluster configuration, some prompts are not displayed.

Table 3-2 Prompts for OpenVMS Cluster Configurations

Question	How to Respond
Will this node be a cluster	Enter Y.
member (Y/N)?
What is the node's DECnet node	Enter the DECnet node name (for example, MYNODE). The DECnet node name
name?	can be from one to six alphanumeric characters in length and cannot include
	dollar signs ($) or underscores (_). This is the name you specified in step 12 of
	the installation procedure.

What is the node's DECnet node address?

Enter this cluster's group number:1

Enter this cluster's password:1

Reenter this cluster's password for verification:

Will MYNODE be a disk server (Y/N)?

Enter a value for MYNODE’s ALLOCLASS parameter.

Does this cluster contain a quorum disk (Y/N)?

Enter the DECnet node address; for example, 2.2. This is the address you specified in step 13 of the installation procedure.

Enter a number in the range of 1 to 4095 or 61440 to 65535.

Enter the cluster password. The password must be from 1 to 31 alphanumeric characters in length and can include dollar signs ($) and underscores (_).

Reenter the password.

Enter Y if you want local disks to be served to the cluster (mandatory for local area and mixed-interconnect configurations). See the HP OpenVMS Cluster Systems manual for information about served cluster disks.

In an OpenVMS Cluster environment, the allocation class value cannot be zero if volume shadowing will be used on this system. The ALLOCLASS value must be a number from 1 to 255.

HP recommends that you thoroughly review the chapter on cluster storage devices in the HP OpenVMS Cluster Systems manual. This manual also includes the rules for specifying allocation class values.

For SCSI, local area, and mixed-interconnect configurations, enter Y or N, depending on your configuration. If you enter Y, the system asks for the name of the quorum disk. Enter the device name of the quorum disk. For information about quorum disks, see the HP OpenVMS Cluster Systems manual.

1Cluster 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.
