From the New Install Menu, execute the additional options for configuring the HCP system. Each option either opens a lower-level menu with configuration options or opens a page in the wizard that displays a prompt to enter a value for a configuration setting.

For pictures of all of the HCP Setup wizard menus, see Appendix B: HCP Setup wizard menus.

To configure the HCP sysem:

  1. Enter 3 to change these networking settings:
    • One or more of the IPv4 and IPv6 gateway IP addresses that you specified during the OS installation
    • Multicast IP addresses
  2. Enter 4 to change these DNS settings:
    • Whether HCP should use DNS services
    • Domain name for the HCP system (this is required regardless of whether you use DNS).
    • The list of IPv4 and IPv6 addresses the HCP needs to use to forward DNS requests to each of your corporate servers
      Note: Each DNS server IP address that you specify must be routable from the [hcp_system] network.
      Tip: If the front-end network IP mode is set to Dual, you should specify both IPv4 and IPv6 DNS server IP addresses. This ensures that all client requests can use the HCP system domain name for access to the system, regardless of which types of IP addresses each client is configured to use.
  3. Enter 5 to change these time settings:
    • Whether the time source is internal or external, and if it’s external, the IP addresses or hostnames of the time servers that you want to use with HCP.
      Note:
      • HCP creates a comma-delimited list of the external time server IP addresses and hostnames that you specify. The comma-delimited list of external time servers can be at most 143 characters long (including the commas).
      • Each external time server IP address that you specify must be routable from the [hcp_system] network. If you specify the hostname of an external time server, that server must have at least one IPv4 or IPv6 address that’s routable from the [hcp_system] network.
    • Optionally, if the time source is set to internal, the current date and time entered in the following format: MMDDhhmmYYYY. MM is the month, DD is the day, hh is the hour (24-hour format), mm is the minute, and YYYY is the year.
    • Time zone.
      Tip: To see a list of valid time zones, enter view. To return to the prompt to enter a time zone for the HCP system, press Q.
    • Time compliance mode.
  4. Enter 6 to change these internal settings:
    • Whether the HCP storage is internal or external.

      If you specify internal storage, continue by selecting the option to set the serial number for the system.

      If you specify exernal storage, the wizard prompts you to:

      1. Enter y or yes to indicate that the storage is shared with other applications, or enter n or no to indicate that the storage is used exclusively for HCP.
        Shared Storage
=============================================

You have chosen external storage. External storage may or may not be shared
with other applications or systems on a customer site. If it is shared, the
installation system will work on a maximum of two nodes at a time, with two
mkfs processes running on each node. You can change this later, if necessary,
by modifying the “max_simul_nodes” and “max_simul_mkfs” values in the
cluster.cfg file.

Note: Do not modify cluster.cfg without instructions from HCP Support.

Note: Control-C cancels input.

Is this shared external storage.
[Default: no]:

        If you answer y or yes, HCP Setup slows down its formatting during installation to minimize the disruption to the other applications that use the shared storage.

      2. Enter y or yes to indicate that the HCP system uses blade servers, or enter n or no to indicate that the HCP system doesn’t use blade servers.
        Blade Servers
=============================================

You have chosen external storage. External storage works with multiple server platforms.

Note: Control-C cancels input.

Does this HCP system use blade servers?
[Default: no]:

        If you answer y or yes, the wizard prompts you to enter the IP addresses that HCP needs to use to communicate with the blade server chassis.

      At this point, if you’ve specified external storage, HCP Setup analyzes the identified storage nodes to determine whether they have any logical volumes in the index-only and spindown ranges:

      1. If HCP Setup finds any index-only volumes, the wizard prompts you to indicate whether you want to enable index-only volumes.
        MQE Index-Only Volumes
=============================================

Do you want to enable MQE index-only volumes?

Note: Control-C cancels input.

Enter yes or no.
[Default: no]:

        In response to this prompt, enter y or yes to enable index-only volumes or n or no if you don’t want to enable them.

        If you enter y or yes and all the storage nodes have the same number of index volumes (more than one each), the wizard lists all the index volumes and prompts you to confirm that the list is correct:

        • Enter y or yes to confirm that the list is correct and continue the installation.
        • Enter n or no to return to the HCP Configuration Menu.

          If the list of index volumes is not correct, tell your SAN administrator to reconfigure the logical volumes at the storage tier. After the reconfiguration is complete, reinstall the OS on the affected nodes. Then start the HCP software installation procedure again.

          If you enter y or yes and not all the storage nodes have the same number of index volumes, or if you enter n or no, the wizard returns an error.

          After returning an error, the wizard prompts you to press Enter:

          1. Press Enter.

            The HCP Configuration Menu reappears.

          2. If the storage configuration is incorrect, tell your SAN administrator to reconfigure the logical volumes at the storage tier. Then wait until the reconfiguration is complete.
          3. Reinstall the OS on the affected nodes. Then start the HCP software installation procedure again.
      2. If HCP Setup finds any spindown volumes, the wizard prompts you to indicate whether you want to enable spindown.
        Spindown Volumes
=========================================

Do you want to enable spindown?

Note: Control-C cancels input.

Enter yes or no.
[Default: no]:

        In response to this prompt, enter y or yes to enable spindown or n or no if you don’t want to enable it:

        • If you enter y or yes, the wizard prompts you to enter the IP addresses that HCP needs to use to communicate with the controllers in each of the storage arrays that have spindown volumes for the HCP nodes.
          Configure Spindown Storage Arrays
=============================================
Spindown is enabled. Now you need to provide IP addresses for controller 0
and controller 1 on each new storage array that you are adding to the system.
HCP will then verify the connectivity to the array, proper licensing for
spindown, and the correct configuration of logical volumes.

Enter the IP address for array controller 0:

          After you enter all of the controller IP addresses, the wizard lists all the spindown volumes and prompts you to confirm that the list is correct, enter y or yes to confirm that the list is correct and continue the installation or enter n or no to return to the HCP Configuration Menu.

          If the list of spindown volumes is not correct, tell your SAN administrator to reconfigure the logical volumes at the storage tier. After the reconfiguration is complete, reinstall the OS on the affected nodes. Then start the HCP software installation procedure again.

        • If you enter n or no, the wizard returns an error. To continue, press Enter, reinstall the OS on the affected nodes, and start the HCP software installation procedure again.
    • HCP system serial number.
    • Whether replication is enabled. Replication is enabled by default.
    • Whether reinstallation with DNS failover is in effect. When you select this option, the wizard prompts for whether this is a reinstallation of a system in a replication pair with DNS failover enabled.

      If you enter y or yes in response to this prompt, HCP continues to redirect requests that target replicated namespaces on the current system to the other system in the replication pair until failback occurs.

      Reinstallation with DNS Failover in Effect
=============================================

DNS failover is the process by which one system in a failed-over replication
link is able to service requests targeted to the other system in the link when
that other system is unavailable. If this is a reinstallation of the
unavailable system with DNS failover enabled, you can choose to have this
redirection continue until, for an active/active link, the link is failed back
or, for an active/passive link, data recovery is complete.

Note: Control-C cancels input.

If this is the reinstallation of an unavailable system with DNS failover in effect,
do you want to continue the redirection of requests targeted to this system?
