Посмотри состояние iscsi после логина (iscsiadm -m session -P 3), если
там есть что-то, то в районе |grep disk оно будет примерно такого вида:

Добрый день
Очень странная ситуация. Есть 2 сервера Debian Stable. На том который начинался
как тестинг а потом перешел в stable все работает, а на втором,
свежеустановленом 6.0.2 с той-же конфигурацией - не работает.
Стоит udev, open-iscsi. Подключаем iscsi (делаем дискавери, ставим
автоматическое подключение) - в логах никаких ошибок, но нету /dev/sd*, нет
/dev/disk/by-*
Останавливаю open-iscsi, делаю руками:

Что это может быть ? Как узнать проблема в iscsi или udev ? Версии на обоих
серверах одинаковые.
