• Конечный автомат — абстрактный автомат без выходного потока, число возможных состояний которого конечно. Результат работы автомата определяется по его конечному состоянию
• http://ru.wikipedia.org/wiki/Конечный_автомат
• Finite state machine (FSM) • В UCS конечными автоматами являются
• Физические компоненты (шасси, модули ввода-вывода, серверы) • Логические компоненты (LAN cloud, политики) • Рабочие процессы (загрузка, обновления ПО, резервное копирование)
• Ценный инструмент при расследовании проблем

• Дефицит индентификаторов • Пулы UUID, MAC, WWNN и WWPN
• Политика настройки локального диска • Должна соответствовать возможностям локального хранения
• vNIC и vHBA назначены одной фабрике • Если в сервисном профиле используются два или более vNIC или
vHBA, назначайте их разным фабрикам

Пул WWNN содержит мало номеров, ассоциация второго профиля потерпела неудачу
© 2010 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 35
Добавьте в пул WWNN больше номеров

• Неверный порядок загрузки сервера • Проблемы с подключениями в случае загрузки через LAN • Неверный WWPN таргета и/или номер LUN в случае загрузки через
SAN • Неверная маска LUN на массиве • Неправильные настройки в BIOS
• Параметры BIOS можно проверить через KVM • Ошибочно подмонтирован не тот виртуальный носитель
