Простой и быстрый способ узнать какие диски установлены в вашей Linux системе
Утилита LSHW Утилита lshw (Linux Hardware Lister ) предназначена для получения детальной информации о компонентах сервера: процессоре, конфигурации оперативной памяти, материнской плате, BIOS информацию, конфигурацию кэша, шины и многое другое (в комплекте с утилитой также имеется база данных оборудования с USB и PCI интерфейсами).
Утилита отсутствует в стандартном наборе, поэтому установку производим самостоятельно, для RHEL достаточно выполнить yum install lshw -y
Для того, чтобы получить информацию о дисковых устройствах системы, выполним команду lshw -class disk -class storage:

Для отображения краткого списка дисков в системе, достаточно выполнить команду lshw -short -C disk

Утилита LSHW Аналогично с предыдущей командой извлекает огромное количество разнообразной информации о дисках. Запускается с ключом -I, указав путь диска, к примеру hdparm -I /dev/sdd:
