    Accessing the System Console Through a Graphics Monitor The SPARC Enterprise T2000 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.

    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 SPARC Enterprise T2000 server IP address, and is dedicated for use only with the ALOM CMT system controller.

  • Page 32: 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 SPARC Enterprise T2000 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 33: Figure 1-3 Patch Panel Connection Between A Terminal Server And A Sparc Enterprise T2000 Server

    If the pinouts for the serial management port do not correspond with the pinouts for the RJ-45 ports on the terminal server, you need to make a crossover cable that takes each pin on the SPARC Enterprise T2000 server serial management port to the corresponding pin in the terminal server’s serial port.

  • Page 45: Alom Cmt Break Or Console Command

    ALOM CMT break or console Command Typing break from the sc> prompt forces a running SPARC Enterprise T2000 server to drop into OpenBoot firmware control. If the operating system is already halted, you can use the console command instead of break to reach the ok prompt.

  • Page 46: For More Information

    Caution – Accessing the ok prompt suspends the Solaris OS. When you access the ok prompt from a functioning SPARC Enterprise T2000 server, you are suspending the Solaris OS and placing the system under firmware control. Any processes that were running under the operating system are also suspended, and the state of such processes might not be recoverable.

  • Page 67: Managing Disk Volumes

    ■ Requirements To configure and use RAID disk volumes on the SPARC Enterprise T2000 server, you must install the appropriate patches. For the latest information on patches for the SPARC Enterprise T2000 server, see the latest product notes for your system.

  • Page 68: 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 SPARC Enterprise T2000 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 two-, three- or four-disk RAID 0 (integrated stripe, or IS) volumes.

  • Page 69: Figure 3-1 Graphical Representation Of Disk Striping

    Graphical Representation of Disk Striping FIGURE 3-1 Caution – There is no data redundancy in an IS volume configuration. Thus, if a single disk fails, the entire volume fails, and all data is lost. If an IS volume is manually deleted, all data on the volume is lost. IS volumes are likely to provide better performance than IM volumes or single disks.

  • Page 70: Hardware Raid Operations

    You can then use the volume in the Solaris operating system. Hardware Raid Operations On the SPARC Enterprise T2000 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 71: Table 3-1 Disk Slot Numbers, Logical Device Names, And Physical Device Names

    In this example, a single IM volume has been enabled. It is fully synchronized and is online. The SPARC Enterprise T2000 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 72 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 75: To Create A Hardware Striped Volume

    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. For example: ok printenv boot-device boot-device = disk ok devalias disk disk /pci@780/pci@0/pci@9/scsi@0/disk@0,0 2.
  • Page 76 As an alternative, you can use the –f option to force the creation if you are sure of the member disks, and sure that the data on all other member disks can be lost.
