Prerequisites

The servers and disk shelves are configured and administered either directly using an administrative client (terminal or terminal emulator) connected to the serial management (SER MGT) port on the server, or indirectly via your network and the network management (NET MGT) port. To access the servers remotely, your network must have a Dynamic Host Configuration Protocol (DHCP) server. Both methods use Oracle ILOM to access the service processor (SP) in the server. For detailed instructions on connecting to Oracle ILOM, see Connecting to Oracle ILOM.

While you must make an Oracle ILOM connection to one server in preparation for initial configuration, it is recommended that you make the connection for both servers and keep them in place for future access to the SPs through Oracle ILOM.

When initially configuring the servers, you connect to either one, but not both. The server you connect to is referred to as the primary server, and the other server is the peer server. It does not matter which server you choose as the primary server.

Each server should be assigned a unique management interface so that it is not used as a cluster data interface. For example, the primary server could use interface igb0 (a typical name) and the peer server could use interface igb1 as the management interfaces. After the system is initially configured, you should lock the management interfaces as described in Clustering Guidelines.

To prepare for connecting to your network and configuring the primary network interface, gather the following information:

• Host name

• Default router IP address

• IP address/netmask for management interface on primary server

• IP address/netmask for management interface on peer server

• IP address/netmask for data interface on primary server (InfiniBand IPMP interface #1)

• IP address/netmask for data interface on peer server (InfiniBand IPMP interface #2)

• DNS parameters:

  • DNS IP address #1/#2

  • DNS IP address #3/#4

  • DNS/NIS/LDAP domain name

• NTP server IP address

• LDAP parameters:

  • Use SSL/TLS? (Yes/No)

  • LDAP server IP address #1/#2 (port)

  • LDAP server IP address #3/#4 (port)

  • LDAP base search DN

  • LDAP search scope recursive? (Yes/No)

  • LDAP authentication method: Simple, SASL/Digest MD5, or SASL/GSSAPI

  • LDAP proxy DN (or anonymous)

  • LDAP proxy DN password

• NIS server IP address #1/#2

• Desired Administrator account password

Network interfaces configured via DHCP cannot be failed over between servers and, therefore, cannot be used by clients to access storage. Be sure to assign static IP addresses to any network interfaces which will be used by clients to access storage, including, if applicable, the network interface used for configuration in section Configure the Primary Network Interface.

To prepare for a serial connection, configure an administrative client with the following settings:

• 8N1: eight data bits, no parity, one stop bit

• 9600 baud

• Disable hardware flow control (CTS/RTS)

• Disable software flow control (XON/XOFF)

Ensure you have met the power source requirements for the servers as stated in Sun Server X3-2 Site Planning Guide, “Preparing the Site for Installation,” at http://docs.oracle.com/cd/E22368_01/index.html.

Ensure you have met the power source requirements for the Oracle disk shelves:

• Provide a suitable power source with electrical overload protection to meet the power supply input voltage range of 100-240 VAC, 50-60 Hz. The disk shelves are compatible with 100-120 VAC or 200-240 VAC sources. The power source must not be overloaded by the total number of disk shelves in the cabinet. At full load, each DE2-24 draws 707.8W.

• The power source must provide a reliable earth connection for each disk shelf and the cabinet.

• Ensure that the power source is easily accessible because the power cord is the main disconnect device for the disk shelf.

Before applying power to the disk shelves or servers, read the section Clustering Guidelines. Also read how to configure storage in the Oracle ZFS Storage Appliance Administration Guide for the appropriate software release at http://www.oracle.com/goto/ZFSStorage/docs.
