  • Page 20: Alternative System Console Configuration

    The serial management port is not a general-purpose serial port. If you want to use a general-purpose serial port with your server, to connect a serial printer for example, use the standard 9-pin serial port on the back panel of the Sun Netra T5440 server. The Solaris OS sees this port as ttya.

  • Page 21: Accessing The System Console Through A Graphics Monitor

    Accessing the System Console Through a Graphics Monitor The Sun Netra T5440 server is shipped without a mouse, keyboard, monitor, or frame buffer for the display of bitmapped graphics. To install a graphics monitor on the server, you must install a graphics accelerator card into a PCI slot, and attach a monitor, mouse, and keyboard to the appropriate front or rear USB ports.

  • Page 22: Activating The Network Management Port

    For more information, refer to your server installation guide, the ILOM user’s guide, and the Integrated Lights Out Management 2.0 Supplement for the Sun Netra T5440 Server. You can assign the network management port a static IP address or you can configure the port to obtain an IP address using DHCP from another server.

  • Page 23: To Activate The Network Management Port

    Data centers frequently devote a separate subnet to system management. If your data center has such a configuration, connect the network management port to this subnet. Note – The network management port is a 10/100 BASE-T port. The IP address assigned to the network management port is a unique IP address, separate from the main server IP address, and is dedicated for use only with the ILOM service processor.

  • Page 24: Accessing The System Console Through A Terminal Server

    1. Complete the physical connection from the serial management port to your terminal server. The serial management port on the Sun Netra T5440 server is a data terminal equipment (DTE) port. The pinouts for the serial management port correspond with the pinouts for the RJ-45 ports on the serial interface breakout cable supplied by Cisco for use with the Cisco AS2511-RJ terminal server.
  • Page 25 Connect a serial interface breakout cable directly to the Sun Netra T5440 server. ■ “Accessing the Service Processor” on page Connect a serial interface breakout cable to a patch panel and use the ■ straight-through patch cable (supplied by your server’s manufacturer) to connect the patch panel to the server.

  • Page 36: Openboot Ok Prompt

    For a full description of run levels, refer to the Solaris system administration documentation. Most of the time, you operate a Sun Netra T5440 server at run level 2 or run level 3, which are multiuser states with access to full system and network resources.

  • Page 37: Openboot™ Ok Prompt Not Available After The Solaris Os Starts

    OpenBoot™ ok Prompt Not Available After the Solaris OS Starts The OpenBoot firmware is not available and might be removed from memory once the Solaris OS starts. To reach the ok prompt from the Solaris OS, you must first halt the domain. Use the Solaris OS halt(1M) command to halt the domain.

  • Page 55: Auto-Boot Options

    Auto-Boot Options The system firmware stores a configuration variable called auto-boot?, which controls whether the firmware will automatically boot the operating system after each reset. The default setting for Sun Netra platforms is true. Normally, if a system fails power-on diagnostics, auto-boot? is ignored and the system does not boot unless an operator boots the system manually.

    If keyswitch_state is set to diag, the system can power itself on using preset values of diagnostic properties (/HOST/diag level=max, /HOST/diag mode= max, /HOST/diag verbosity=max) to provide thorough fault coverage. This option overrides the values of diagnostic properties that you might have set elsewhere.

  • Page 66: Raid Technology

    By providing this logical volume management layer, the software overcomes the restrictions imposed by physical disk devices. The onboard disk controller of the Sun Netra T5440 server provides for the creation of as many as two hardware RAID volumes. The controller supports either two-disk RAID 1 (integrated mirror, or IM) volumes, or up to eight-disk RAID 0 (integrated stripe, or IS) volumes.

  • Page 67: Integrated Mirror Volumes (Raid 1)

    Integrated Stripe volumes provide for a logical unit (LUN) that is equal in capacity to the sum of all its member disks. For example, a three-disk IS volume configured on 72-gigabyte drives will have a capacity of 216 gigabytes. Graphical Representation of Disk Striping FIGURE 3-1 Caution –...

  • Page 68: Hardware Raid Operations

    You can then use the volume in the Solaris OS. Hardware Raid Operations On the Sun Netra T5440 server, the SAS controller supports mirroring and striping using the Solaris OS raidctl utility. A hardware RAID volume created under the raidctl utility behaves slightly differently than one created using volume management software.

  • Page 69: To Create A Hardware Mirrored Volume

    In this example, a single IM volume has been enabled. It is fully synchronized and is online. The Sun Netra T5440 server’s on-board SAS controller can configure as many as two RAID volumes. Prior to volume creation, ensure that the member disks are available and that there are not two volumes already created.
  • Page 70 See the raidctl(1M) man page for additional details regarding volume and disk status. Note – The logical device names might appear differently on your system, depending on the number and type of add-on disk controllers installed.

  • Page 72: To Create A Hardware Mirrored Volume Of The Default Boot Device

    This section describes the procedure required to create a hardware RAID volume containing the default boot device.

One alternate medium is a network installation image in single-user mode (refer to the Solaris 10 Installation Guide for information about configuring and using network-based installations). 1. Determine which disk is the default boot device From the OpenBoot ok prompt, type the printenv command, and if necessary the devalias command, to identify the default boot device.
