    Activating the Network Management Port The network management port is configured by default to retrieve network settings using DHCP and allow connections using SSH. You may need to modify these settings for your network. If you are unable to use DHCP and SSH on your network, you must connect to ALOM CMT through the system controller using the serial management port to reconfigure the network management port.

  • Page 33: Switching Between The System Controller Prompt And The System Console

    Switching Between the System Controller Prompt and the System Console The server features two management ports, labeled SER MGT and NET MGT, located on the server’s rear panel. If the system console is directed to the virtual- console device (its default configuration), these ports provide access to both the system console and the ALOM CMT command-line interface (also called the system controller prompt, see FIGURE 1-5...

    The system controller runs independently of your server and regardless of system power state. When you connect your server to AC power, the system controller immediately starts up and begins monitoring the system. Sun SPARC Enterprise T1000 Server Administration Guide • April 2007...

  • Page 35: Access Through Multiple Controller Sessions

    Note – To view system controller boot messages, you must connect an alphanumeric terminal to the serial management port before connecting the AC power cords to the server. You can log in to the system controller at any time, regardless of system power state, as long as AC power is connected to the system and you have a way of interacting with the system.

  • Page 37: Methods To Reach The Ok Prompt

    It is the last of these scenarios which most often concerns you as an administrator, since there will be times when you need to reach the ok prompt. The section “Methods To Reach the ok Prompt” on page 19 lists several ways. For detailed instructions, see “Getting to the ok Prompt”...

    Use this method only when nothing else works. Caution – Accessing the ok prompt suspends the Solaris OS. Sun SPARC Enterprise T1000 Server Administration Guide • April 2007...

  • Page 39: For More Information About Openboot Firmware

    When you access the ok prompt from a functioning 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 41: System Console Openboot Configuration Variable Settings

    System Console OpenBoot Configuration Variable Settings The server’s system console is directed to the serial management and network management ports (SER MGT and NET MGT) by default. Certain OpenBoot configuration variables control from where system console input is taken and to where its output is directed. The table below shows how to set these variables in order to use the serial management and network management ports.

  • Page 49: Autoboot Options

    Automatic system recovery functionality enables the system to resume operation after experiencing certain nonfatal hardware faults or failures. When ASR is enabled, the system’s firmware diagnostics automatically detect failed hardware components. An autoconfiguring capability designed into the system firmware enables the system to unconfigure failed components and to restore system operation.

    C H A P T E R Managing Disk Volumes This document describes redundant array of independent disks (RAID) concepts, and how to configure and manage RAID disk volumes using the server’s on-board serial attached SCSI (SAS) disk controller. This chapter contains the following sections: “RAID Requirements”...

  • Page 58: Raid Technology

    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 two-disk IS volume configured on 72 GByte drives will have a 144 GByte capacity. Sun SPARC Enterprise T1000 Server Administration Guide • April 2007...

  • Page 59: Integrated Mirror Volumes (Raid 1)

    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 60: Hardware Raid Operations

    These error messages typically refer to a failed hard drive by its physical device name (such as ) or by its logical /devices/pci@7c0/pci@0/pci@8/scsi@2/sd@1,0 device name (such as ). In addition, some applications might report a disk c0t0d0 slot number (0 or 1). Sun SPARC Enterprise T1000 Server Administration Guide • April 2007...
