Use this section to gather required configuration settings
that you need to know before you begin the configuration steps.
To configure the HMC, you must understand
the
related concepts, make decisions and prepare information.
This section describes the information you will
need to connect your HMC to the following:
- Service processors
in your managed systems
- Logical partitions on those managed
systems
- Remote workstations
- IBM Service,
to implement “call-home”
functions
To prepare for HMC configuration, do the following:
- Obtain and install the latest level of the HMC code version you
want to install.
- Determine the physical location of the HMC
in relation to the
servers it will manage. If the HMC is more than 25 feet from its managed
system, you must provide web browser access to the HMC from the managed
system's location so that service personnel can access the HMC.
- Identify
the servers that the HMC will manage.
- Determine whether you
will use a private or an open network to
manage servers. If you decide to use a private network, use DHCP,
unless you are using a Cluster Systems Management (CSM) configuration.
CSM does not support IPv6. To access CSM, you must have two networks.
For more information about CSM, see the documentation that was provided
with that feature. For more information about private and open networks,
see Private and open networks in the HMC environment.
- If you will use an open network to manage an FSP, you must set
the FSP's address manually through the Advanced System Management
Interface menus. A private, non-routable network is recommended.
- If you have two HMCs, designate a primary and secondary HMC. The
primary HMC should be physically closer to the machine, and should
be the HMC that is configured to call home.
- Determine the
network settings that you will need to connect the
HMC to remote workstations, logical partitions, and network devices.
- Define how the HMC will “call home.” Call home options include
either over an outbound-only Secure Socket Layer (SSL) Internet connection,
a modem, or a Virtual Private Network (VPN) connection.
- Determine
the HMC users that you will create and their passwords,
as well which roles they will be given. You must assign the hscroot
and hscpe users a password.
- Document the following company
contact information that will be
needed when configuring call home:
- Company name
- Administrator
contact
- Email address
- Telephone numbers
- Fax
numbers
- The street address of the HMC's physical location
- If you plan to use email to notify operators or systems
administrators
when information is sent to IBM Service through call-home, identify
the Simple Mail Transfer Protocol (SMTP) server and the email addresses
you will use.
- You must define the following passwords:
- The
access password that will be used to authenticate the HMC
to the FSP
- The ASMI password that will be used for the admin user
- The ASMI password that will be used for the general user
Create the passwords when you connect from the HMC to a new server
for the first time. If the HMC is a redundant or second HMC, obtain
the HMC User password and be prepared to enter it when connecting
the first time to the managed server's FSP.
When you have completed these
preparation steps, complete the Preinstallation configuration worksheet for the HMC.
