Как узнать информацию о дисках в системе

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:

# lshw -class disk -class storage

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

# 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:

# hdparm -I /dev/sdd
