HP Insight Control for Linux 6.0 Installation Guide

Table 5-1 Insight Control for Linux installation questions (continued)
Description and user actionQuestion
You must enter root as the Systems Insight Manager user name. This root user is
the same as the root user on the Linux system.
This user name and its password are used to import an SSL certificate into the Systems
Insight Manager trusted certificate pool. After the certificate is imported, Insight
Control for Linux monitoring software can communicate with Systems Insight
Manager without asking for a password. This password is not saved or stored on
the CMS.

You only want to consider exporting the /hptc_cluster file system if you plan
to configure multiple management hubs other than the CMS.
Insight Control for Linux can manage and monitor as many as a thousand servers
through the use of management hubs, which are servers that are responsible for
monitoring a subset of managed systems.
Exporting the
/hptc_cluster file system
to the management hubs
By defining multiple servers to acts as hubs, the monitoring load is distributed across
multiple servers. The general guideline is to assign one management hub for every
256 managed systems.
For a management hub to monitor clients, the management hubs must have access
to all managed systems and have access to the console port of each managed system.
Therefore, management hubs cannot be on a private network with no external access
to the managed systems.
If you elect to export the /hptc_cluster file system, the OS on the CMS and the
OS on the management hubs must be the same architecture type (that is, all 64-bit
or all 32-bit). Otherwise, the metric data cannot be viewed from the hub nodes.
The HP Insight Control for Linux User Guide describes how to manually add the host
names of the servers you want to act as management hubs to the Management_Hubs
subcollection at the appropriate time. You do not have to do that before or during
the installation process.
The /hptc_cluster file system stores monitoring data collected by the management
hubs. If your company policy does not prevent you from using NFS, HP recommends
exporting the /hptc_cluster file system. Doing so enables you to access all
monitoring data from any management hub. For example, you are able to view the
consolidated log file from any management hub and use the shownode metrics
command to view metric data from any hub. If you export the /hptc_cluster file
system you must open up the required NFS ports on the CMS as described in
Section 3.4.2.6 (page 25).
All Insight Control for Linux monitoring features are available regardless of whether
or not you elect to export the /hptc_cluster file system. An added benefit to
exporting /hptc_cluster is the ability to view all monitoring data and log files
from any management hub.
If you decide not to export the /hptc_cluster file system, you will only be able
to view monitoring data from the shownode metrics command output and the
consolidated log file from the CMS.
5.2.1 DHCP server configuration questions
Table 5-2 provides information about how to answer the DHCP server configuration questions
presented by the install.sh script.
If you want to configure the CMS to be a DHCP server, you must supply the information listed
in Table 5-2. All questions have a default response, and it safe to accept the default responses
only if you are configuring the DHCP server for a private network.
