You can manage security data for an OpenVMS Cluster system
with SYSMAN CONFIGURATION commands.
SYSMAN CONFIGURATION Commands summarizes these CONFIGURATION commands and their
functions.
Table 4 SYSMAN CONFIGURATION Commands
Command

CONFIGURATION
SET CLUSTER_AUTHORIZATION
Modifies the group number
and password in a local area cluster
CONFIGURATION SHOW CLUSTER_AUTHORIZATION
Displays the group number and multicast
address of a local area cluster
Modifying
the Group Number and Password The group number identifies the group of nodes in the cluster,
and the associated Ethernet address is used to send messages to
all nodes in the cluster. The OpenVMS Cluster password protects
the integrity of the cluster membership.
Using the CONFIGURATION SET CLUSTER_AUTHORIZATION command
modifies the group number and password, as recorded in SYS$SYSTEM:CLUSTER_AUTHORIZE.DAT.
Normally, you do not need to alter records in the CLUSTER_AUTHORIZE.DAT
file.
If your configuration has multiple system disks, SYSMAN automatically
updates each copy of CLUSTER_AUTHORIZE.DAT, provided that you have
defined the environment as a cluster with the SET ENVIRONMENT/CLUSTER
command.
If you change either the group number or password,
you must reboot the entire cluster.
You cannot display the cluster password for security reasons,
but you can display the group number and group multicast address
with the CONFIGURATION SHOW CLUSTER_AUTHORIZATION command.
The following
command example sets the environment to a specific cluster, sets
privilege to SYSPRV, and modifies the cluster password:
SYSMAN> SET ENVIRONMENT/CLUSTER/NODE=NODE21SYSMAN> SET PROFILE/PRIVILEGE=SYSPRVSYSMAN> CONFIGURATION SET CLUSTER_AUTHORIZATION/PASSWORD=GILLIAN%SYSMAN-I-CAFOLDGROUP, existing group will not be changed%SYSMAN-I-GRPNOCHG, Group number not changedSYSMAN-I-CAFREBOOT, cluster authorization file updated.The entire cluster should be rebooted.
The following command example displays the group
number and multicast address for NODE21. Because the group number
and password on other nodes in the cluster are identical, no further
information is displayed.
SYSMAN> CONFIGURATION SHOW CLUSTER_AUTHORIZATIONNode NODE21: Cluster group number 65240
Multicast address: AB-00-04-01-F2-FF
