Ii. Attach a hard disk

1. Create a directory on the local hard disk.

#mkdir /opt/data/tmp1

2. mount a partition in the second Hard Disk/dev/sdb1Totmp1

#mount /dev/sdb1 /opt/data/tmp1

3. Check whether the disk is mounted.

# df -hFilesystem Size Used Avail Use% Mounted on/dev/sda1 2.0G 141M 1.8G 8% /none 1014M 0 1014M 0% /dev/shm/dev/sda2 4.0G 1.8G 2.0G 47% /opt/dev/sda7 18G 168M 17G 1% /opt/data/dev/sda5 4.0G 1.4G 2.4G 37% /usr/dev/sda3 4.0G 2.1G 1.8G 55% /var/dev/sdb1 3.9G 1.4G 2.3G 38% /opt/tmp/tmp1

3. Detach a hard disk

#umount /dev/sdb1
