If during the installation you answer YES to the
system prompt asking whether your system will be a member of an OpenVMS
Cluster, you need to provide the following information after you boot
the system disk:
Type of configuration
types (CI, DSSI, SCSI, local area, or mixed-interconnect) are distinguished
by the interconnect device that the VAX, Alpha, or Integrity server
computers in the OpenVMS Cluster use to communicate with one another.
HP Integrity servers do not support CI, DSSI, or MEMORY CHANNEL devices.
DECnet node name and node address
the DECnet node name and node address for the computer on which you
are installing the OpenVMS operating system, consult the network or
system manager. If you install DECnet-Plus for OpenVMS (Phase V)
software and do not plan to use DECnet Phase IV for OpenVMS addresses,
then you do not need to provide this information.
Allocation class value
installation procedure, you might be asked for the allocation class
value (ALLOCLASS) of the computer on which you are installing the
OpenVMS operating system. For example:
Enter a value for this_node ALLOCLASS parameter:
In an OpenVMS Cluster environment, the allocation class
value cannot be zero if the node serves DSSI or CI disks to other
cluster members, or if volume shadowing will be used on this system
or in the cluster. In either case, the ALLOCLASS value must be a number
from 1 to 255 and cannot be a number
in use by another system in the cluster.
you enter the allocation class value, the installation procedure uses
it to automatically set the value of the ALLOCLASS system parameter.
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
Whether you want a quorum disk
To help you
determine whether you need a quorum disk in the cluster, see the HP OpenVMS Cluster Systems manual.
Location of the page and swap files
nonclustered system, the page and swap files are on one or more local
disks, but on a clustered system, the files might be on one or more
local or clustered disks. See the HP OpenVMS Cluster Systems manual to help you determine where the page and swap files will
be located for the system on which you are installing the OpenVMS
operating system software.
If you are going to set
up a local area or mixed-interconnect cluster that is LAN-based (Gigabit
Ethernet), use the following rules to determine the cluster group
number and password:
Cluster group number—A number in the range
from 1 to 4095 or 61440 to 65535.
Cluster password—Must be from 1 to 31 alphanumeric
characters in length and can include dollar signs ($) and underscores(_).
 Servers that use the Maintenance Operations Protocol (MOP).
 Cluster group number and password are required by any cluster
nodes that use the local area network for cluster communications.
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.
