Sun fire t2000 linux

Продолжаем игры с подопытным T2000 — этап, делимся мощностью

Сегодня продолжу описывать испытания, на уже знакомом нам по предыдущему посту серверу Sun Fire T2000. Необходимо попробовать насколько безболезненно пройдет установка на такую машинку свеженького Oracle VM (бывший Ldom) и запуск в ней Solaris. Так сказать тренировочный забег перед официальной работой. Кому-нибудь да пригодится подробный мануал.

Ну что же, начнем, для начала нам необходимо скачать сей пакет, это можно сделать с официального сайта Oracle (может потребовать регистрации), либо отсюда — p12569204_210_SOLARIS64 (1).zip
, залил для ленивых.
Обязательно необходимо проверить соответствует ли Ваше железо критериями Oracle (прошивка, версия Solaris и.т.д.). Для читателей я освещу:

Ну предположим, что все у нас в порядке, мы скачали необходимый софт и готовы к установке, естественно нам необходимо подготовить место, где будет располагаться виртуальный диск гостевой ОС. Для этого я выделил немного места на 2-х дисках объединил их в зеркальный пул
ZFS.

Вы видите, на нем занятое место, это предварительно созданный файл image(который и будет нашим виртуальным диском), файл был создан с помощью команды dd, это выглядело примерно так:

root@T2000 # dd if=/dev/zero of=/OracleVM/image bs=1024 count=10000000

Инсталяция Oracle VM более чем простая, распаковав скачанный архив, проходим в папку Install и видим там единственный скрипт, который и запускаем:

Полученный результат говорит нам, что все прошло успешно. Значит можно переходить к следующим шагам, вот тут и начнется самое интересное. Первое конфигурируем службы нашего VM, это три службы:
vcc — виртуальная консоль
vds — виртуальный диск
vsw — виртуальный свитч
Для этого вводим следующие команды, в дальнейшем будет понятно использование всех опций и аргументов.

В результате мы успешно присвоили виртуальные устройства, нашему primary домену. Теперь переходим к выделению физических ресурсов для гостевого домена. Мы знаем параметры нашего сервера, но чтобы еще раз убедиться что у нас есть вводим командочку:

Это достаточная информация для того, чтобы мы смогли сконфигурировать primary систему с учетом гостевой.

root@T2000 # ldm set-vcpu 8 primary
Crypto unit 2 was removed from domain primary

Далее будут следовать команды, которые я опишу чуть ниже.

root@T2000 # ldm start-reconf primary
Initiating a delayed reconfiguration operation on the primary domain.
All configuration changes for other domains are disabled until the primary
domain reboots, at which time the new configuration for the primary domain
will also take effect.
root@T2000 # ldm set-memory 4G primary
root@T2000 # ldm add-config initial
root@T2000 # ldm list-config
factory-default
initial [current]

После ввода данных команд мы получили, новую конфигурации загрузки нашего сервера. Далее нам необходимо перезагрузиться для того, чтобы продолжить нашу настройку.

root@T2000 # shutdown -y -g0 -i6

В процессе загрузки, мы уже видим, что оперативной памяти, как мы и заказали 6Гб. Дальше допиливаем нашу сеть:

Из вывода видно, как мы подключили виртуальную сеть, и сказали ей получить ip по dhcp.
Проверим службы виртуальных терминалов:

root@T2000 # svcs -a | grep vntsd
online 17:20:25 svc:/ldoms/vntsd:default

Убедившись, что все работает, переходим к конфигурации железа для гостевой ОС, операции похожи на конфигурирование primary системы

root@T2000 # ldm add-domain VMtest
root@T2000 # ldm add-vcpu 4 VMtest
root@T2000 # ldm add-memory 2G VMtest
root@T2000 # ldm add-vnet vnet1 primary-vsw0 VMtest
root@T2000 # ldm add-vdsdev /OracleVM/image vol1@primary-vds0
root@T2000 # ldm add-vdisk vdisk1 vol@primary-vds0 VMtest
root@T2000 # ldm set-var auto-boot\?=true VMtest
root@T2000 # ldm set-var boot-device=vdisk1 VMtest

В этих нескольких строчках и скрыта вся конфигурация нашего гостевого домена, объясним их по одной:
1 — добавляем домен и называем его
2 — добавляем процессоры в домен
3 — добавляем оперативную память
4 — добавляем виртуальную сеть созданную до этого и называем ее vnet1
5 — ассоциируем предварительно созданный файл как устройство
6 — добавляем это устройство как виртуальный диск
7,8 — говорим гостевой системе загружаться именно с него.

Далее фиксируем все произошедшее привязкой устройств к домену. И проверяем все это.

Теперь очередь установки самого соляриса непосредственно на железку, для этого буду использовать живой DVD привод, но также поддерживается установка из образа ISO.
Для того, чтобы наша гостевое железо перехватило DVD привод, первоначально необходимо отключить службу контролирующую это в primary домене.

root@T2000 # svcadm disable volfs
root@T2000 # ldm unbind VMtest
root@T2000 # ldm add-vdsdev /dev/dsk/c1t0d0s2 dvd_vol@primary-vds0
Path /dev/dsk/c1t0d0s2 is not valid on service domain primary
root@T2000 # ldm add-vdsdev -q /dev/dsk/c1t0d0s2 dvd_vol@primary-vds0
root@T2000 # ldm add-vdisk vdisk_dvd_media dvd_vol@primary-vds0 VMtest

В этих командах мы указываем гостевой ОС, что теперь она будет использоваться живой DVD диск, как свой собственный, и делаем мы это с помощью ключа q потому что иногда без него никак. Далее привязываем железо к гостевому домену вновь, но также используя опцию q и стартуем.

root@T2000 # ldm bind -q VMtest
root@T2000 # ldm start VMtest
LDom VMtest started

Далее нам остается подключиться по телнету к порту обозначенному заранее и продолжить установку.

А дальше, если все пройдет хорошо, мы получим еще одну ОС на своей железке.
Благодарю всех за внимание.

Hardware-Assisted Cryptography

The UltraSPARC T1 multicore processor provides hardware-assisted acceleration of RSA and DSA cryptographic operations. The Solaris 10 Operating System provides the multithreaded device driver ( ncp device driver) that supports the hardware-assisted cryptography.

Remote Manageability With ALOM CMT

The Advanced Lights Out Management (ALOM CMT) feature is a system controller that enables you to remotely manage and administer the Sun Fire T2000 server.

The ALOM CMT software is preinstalled as firmware, and initializes as soon as you apply power to the system. You can customize ALOM CMT to work with your particular installation.

ALOM CMT enables you to monitor and control your server over a network, or by using a dedicated serial port for connection to a terminal or terminal server. ALOM CMT provides a command-line interface that you can use to remotely administer geographically distributed or physically inaccessible machines. In addition, ALOM CMT enables you to run diagnostics (such as POST) remotely that would otherwise require physical proximity to the server’s serial port.

You can configure ALOM CMT to send email alerts of hardware failures, hardware warnings, and other events related to the server or to ALOM CMT. The ALOM CMT circuitry runs independently of the server, using the server’s standby power. Therefore, ALOM CMT firmware and software continue to function when the server operating system goes offline or when the server is powered off. ALOM CMT monitors the following Sun Fire T2000 server components:

CPU temperature conditions

Disk drive status

Enclosure thermal conditions

Fan speed and status

Power supply status

For information about configuring and using the ALOM system controller, refer to the Advanced Lights Out Management (ALOM) CMT Guide .

System Reliability, Availability, and Serviceability

Reliability, availability, and serviceability (RAS) are aspects of a system’s design that affect its ability to operate continuously and to minimize the time necessary to service the system. Reliability refers to a system’s ability to operate continuously without failures and to maintain data integrity. System availability refers to the ability of a system to recover to an operational state after a failure, with minimal impact. Serviceability relates to the time it takes to restore a system to service following a system failure. Together, reliability, availability, and serviceability features provide for near continuous system operation.

To deliver high levels of reliability, availability, and serviceability, the Sun Fire T2000 server offers the following features:

Hot-swappable hard drives

Redundant, hot-swappable power supplies (two)

Redundant hot-swappable fan units (three) and one blower unit

Internal hardware drive mirroring (RAID 1) and striping (RAID0)

Error detection and correction for improved data integrity

Easy access for most component replacements

For more information about using RAS features, refer to the Sun Fire T2000 Server Administration Guide .

Hot-Swappable Components

Sun Fire T2000 server hardware is designed to support hot-swapping of the chassis-mounted hard drives, fan units, and power supplies. By using the proper software commands, you can install or remove these components while the system is running. Hot-swap technology significantly increases the system’s serviceability and availability by providing the ability to replace hard drives, fan units, and power supplies without service disruption.

Power Supply Redundancy

The Sun Fire T2000 server features two hot-swappable power supplies, enabling the system to continue operating should one of the power supplies fail or if one power source fails.

The Sun Fire T2000 server also has a single hot-swappable blower unit that works in conjunction with the power supply fans to provide cooling for the internal disk drives. If the blower unit fails, the three functioning fan units provide enough cooling to keep the system running.

Fan Redundancy

The Sun Fire T2000 server features three hot-swappable system fans. The fans enable the system to continue operating with adequate cooling in the event that one of the fans fails.

Environmental Monitoring

The Sun Fire T2000 server server features an environmental monitoring subsystem protects the server and its components against:

Lack of adequate airflow through the system

Power supply failures

Temperature sensors are located throughout the system to monitor the ambient temperature of the system and internal components. The software and hardware ensure that the temperatures within the enclosure do not exceed predetermined safe operation ranges. If the temperature observed by a sensor falls below a low-temperature threshold or rises above a high-temperature threshold, the monitoring subsystem software lights the amber Service Required LEDs on the front and back panel. If the temperature condition persists and reaches a critical threshold, the system initiates a graceful system shutdown. In the event of a failure of the system controller, backup sensors protect the system from serious damage, by initiating a forced hardware shutdown.

All error and warning messages are logged in the ALOM CMT event log and are optionally sent to the system controller (SC) system console. Service Required LEDs remain lit after an automatic system shutdown to aid in problem diagnosis.

The power subsystem is monitored in a similar fashion by monitoring power supplies and reporting any fault in the front and rear panel LEDs.

If a power supply problem is detected, an error message is logged in the ALOM CMT event log and optionally sent to the SC system console. Additionally, LEDs located on each power supply light to indicate failures. The system Service Required LED lights to indicate a system fault.

Support for RAID Storage Configurations

You can set up a hardware RAID 1 (mirroring) and hardware RAID 0 (striping) configurations for any pair of internal hard drives, providing a high-performance solution for hard drive mirroring.

By attaching one or more external storage devices to the Sun Fire T2000 server, you can use a redundant array of independent drives (RAID) software application such as Solstice DiskSuite or VERITAS Volume Manager to configure system drive storage in a variety of different RAID levels.

Error Correction and Parity Checking

The UltraSPARC T1 multicore processor provides parity protection on its internal cache memories, including tag parity and data parity on the D-cache and I-cache. The internal 3MB L2 cache has parity protection on the tags, and ECC protection on the data.

Advanced ECC, also called chipkill, corrects up to 4-bits in error on nibble boundaries, as long as they are all in the same DRAM. If a DRAM fails, the DIMM continues to function.

Fault Management and Predictive Self Healing

The Sun Fire T2000 server features the latest fault management technologies. The Solaris 10 OS architecture provides a means for building and deploying systems and services capable of predictive self-healing . Self-healing technology enables systems to accurately predict component failures and mitigate many serious problems before they actually occur. This technology is incorporated into both the hardware and software of the Sun Fire T2000 server.

At the heart of the predictive self-healing capabilities is the Solaris Fault Manager, a new service that receives data relating to hardware and software errors, and automatically and silently diagnoses the underlying problem. Once a problem is diagnosed, a set of agents automatically responds by logging the event, and if necessary, takes the faulty component offline. By automatically diagnosing problems, business-critical applications and essential system services can continue uninterrupted in the event of software failures, or major hardware component failures.

Rackmountable Enclosure

The Sun Fire T2000 server uses a space-saving 2U-high rackmountable enclosure that can be installed into a variety of industry standard racks.

The following figures show the physical characteristics of the Sun Fire T2000 server.
