To add a new hard disk for backup on a Red Hat Enterprise Linux (RHEL) system, you will need to perform the following steps:
Connect the hard disk to the system:
Make sure that the hard disk is properly connected to the system. This may involve connecting it to a spare SATA port on the motherboard, or using a USB or eSATA adapter if the hard disk does not have a SATA interface.
Scan for new devices:
Run the following command to scan for new devices:
sudo fdisk -l
This will list all the available block devices on the system. Look for the new hard disk in the list. It should be identified by the device name (e.g., /dev/sdb
).
Create a new partition on the hard disk:
Use the fdisk
command to create a new partition on the hard disk. For example:
sudo fdisk /dev/sdb
Follow the prompts to create a new primary partition on the hard disk. Make sure to specify the correct device name for the hard disk.
Create a new filesystem on the partition:
Use the mkfs
command to create a new filesystem on the partition. For example:
sudo mkfs -t ext4 /dev/sdb1
Replace ext4
with the filesystem type of your choice (e.g., xfs
).
Create a mount point:
Create a new directory to use as the mount point for the hard disk. For example:
sudo mkdir /mnt/backup
Mount the hard disk:
Use the mount
command to mount the hard disk at the mount point. For example:
sudo mount /dev/sdb1 /mnt/backup
After completing these steps, the hard disk should be ready for use as a backup location.
