The network management port is a 10/100BASE-T port with a unique IP address, separate from the server IP address. Like the serial management port, the network management port is dedicated to the system controller.

    As long as a failed component is electrically dormant (not causing random bus errors or signal noise, for example), the system reboots automatically and resumes operation while a service call is made. Once a failed or disabled device is replaced with a new one, the OpenBoot firmware automatically modifies the status of the device upon reboot.

  • Page 77: Domain Minimization

    Domain Minimization One way to contribute to the security of a server is to tailor the installation of software to an essential minimum. By limiting the number of software components installed on each domain (called domain minimization), you can reduce the risks of security holes that can be exploited by potential intruders.

  • Page 81: Integrated Stripe Volumes (Raid)

    Integrated Stripe Volumes (RAID 0) Integrated Stripe volumes are configured by initializing the volume across two or more physical disks, and sharing the data written to the volume across each physical disk in turn, or striping the data across the disks. Integrated stripe volumes provide for a logical unit (LUN) that is equal in capacity to the sum of all its member disks.

    Under hardware RAID volumes, only one device appears in the device tree. Member disk devices are invisible to the operating system, and are accessed only by the SAS controller. Netra T2000 Server Administration Guide • September 2006...

    Slot Numbers and Device Names for Non-RAID Disks To perform a disk hot-swap procedure, you must know the physical or logical device name for the drive that you want to install or remove. If your system encounters a disk error, often you can find messages about failing or failed disks in the system console.

    1. Determine which disk is the default boot device. From the OpenBoot ok prompt, invoke 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.

    If the application watchdog is enabled and you break into the OpenBoot PROM ■ by issuing the break command from the system controller’s sc> prompt, the system controller automatically disables the watchdog timer. Netra T2000 Server Administration Guide • September 2006...
  • Page 103 Note – The system controller displays a console message as a reminder that the watchdog, from the system controller’s perspective, is disabled. However, when you re-enter the Solaris OS, the watchdog timer is still enabled from the Solaris Operating System’s perspective. To have both the system controller and the Solaris OS view the same watchdog state, you must use the watchdog application to either enable or disable the watchdog.

    Using the Watchdog Timer Setting the Timeout Period The LOMIOCDOGTIME IOCTL sets the timeout period of the watchdog. This IOCTL programs the watchdog hardware with the time specified in this IOCTL. You must set the timeout period (LOMIOCDOGTIME) before attempting to enable the watchdog timer (LOMIOCDOGCTL).
