Acabei de ter um servidor dedicado que tem 2x 1TB HDD. No entanto, quando digito df -h , obtenho o seguinte:
[root@sd-56537 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 916G 688G 182G 80% /
tmpfs 7.8G 368K 7.8G 1% /dev/shm
/dev/sda1 194M 61M 124M 34% /boot
Como posso acessar a segunda unidade?
[root@sd-56537 ~]# fdisk -l

Aqui estão algumas coisas que foram tentadas:

As saídas lshw listam o disco ausente como UNCLAIMED :
a node is marked as UNCLAIMED if no specific support for it has been loaded (or lshw has been unable to identify the driver)
Enquanto o disco pode estar conectado, ele pode não estar conectado corretamente ou pode estar com defeito e o driver de disco não pôde reconhecer o disco. A execução de " dmesg | grep 0:0.1.0 " após a inicialização pode revelar mais detalhes sobre isso.
