У нас есть HBA Qlogic QLE2560, работающий на сервере Centos 6. Мне нужно удаленно удалить подключенные LUNS. У меня на устройстве не установлено программное обеспечение от qlogic. Это 2 LUNS, подключенных к P200 G3 SAN, и я не могу найти что-либо задокументированное для этой ОС о том, как их удалить.
