Table G-3 Specific Node-By-Node Output of the Analyze Option
DescriptionColumn Heading
Displays the number of nodes recommended for a particular role based on the
number of nodes in the system.
Recommend
Displays the actual number of nodes assigned with a particular role. Compare this
to the number of nodes shown in the Recommend column to determine how the
current number compares with the HP recommendation. An asterisk (*) in this
column indicates a shortage, indicating that servers may have heavier than optimal
workloads.
Assigned
Indicates a role that HP recommends and the current configuration does not have
it assigned.
Role Recommended (Role Rec)
Indicates that the nodes this role is assigned to (if any) do not include the head
node.
For example, the management_server role must be located on the head node. If
you do not take action, proper operation of the HP XC system is not guaranteed.
Head Node Required (HN Req)
Indicates a role that HP recommends is advantageous to have on the head node,
but you have removed it or moved it to some other node.
Head Node Recommended (HN Rec)
Indicates that an external network connection is required on the node that has this
role. The term required in this case means that the service will not work if an external
network connection is not also present. For example, network address translation
(NAT) will not work if an external network connection is not present.
External Connection Required (Ext Req)
Indicates that an external network connection is recommended on the node that
has this role.
External Connection Recommended (Ext Rec)
Indicates that HP recommends this role be assigned to a dedicated node with no
other roles.
Exclusivity Recommended (Exc Rec)
This column lists all HP XC roles. The term optional indicates that the role is not
part of the recommended default configuration and assigning it to a node depends
upon the configuration you want.
Role
The letter N in any column indicates a configuration issue that is not incorrect but
could be improved.
N (Note)
The letter W in any column indicates a probable incorrect configuration that will
not result in a uncorrectable state, but HP recommends that you correct the
configuration.
W (Warning)
G.7 Customize Service and Client Configurations
The cluster_config utility enables you to add customized services to one or more nodes. The function
of these customized services and where you locate them is entirely up to you and is outside the scope of
this document. Customizing services configuration is intended for expert HP XC users; this feature is
typically not required or intended for the typical HP XC system.
From the command-line menu of the cluster_config utility, enter the letter p to continue the system
configuration process.
