Included on the Live DVD is Screen, a utility which is available when you boot from the Live DVD into the Universal Recovery Console. Screen allows users to manage multiple shells simultaneously over a single Secure Shell (SSH) session or console window. This allows you to perform one task in a terminal window (such as verify mounted volumes) and, while that is running, open or switch to another shell instance to perform another task (such as to run the local_mount utility).
The Screen utility also has its own scroll-back buffer, which enables you to scroll the screen to view larger amounts of data, such as a list of recovery points.
The screen utility starts on the machine booted with the Live DVD by default. However, if you have closed this application, you must start the Screen utility from the Live DVD using the procedure below.
Once the Live DVD ISO image is accessible on the machine on which you want to perform a BMR, and the number and size of volumes matches between the target machine and the recovery point you want to restore to bare metal, then you can launch a restore from the command line using the local_mount utility.
If you want to perform a BMR using the Rapid Recovery Core Console UI, see Selecting a recovery point and initiating a BMR.
This task is a step in Performing a bare metal restore for Linux machines. It is part of the process for Launching a bare metal restore for a Linux machine using the command line.
Complete the steps in this procedure to select a recovery point on the Core to roll back to the physical or virtual BMR target machine.
|Rapid Recovery Core IP address or hostname||The IP address or hostname of the Rapid Recovery Core.||Yes|
|Domain||The domain of the Rapid Recovery Core. This is optional.||No|
|User||The user name for an administrative user on the Core||Yes|
|Password||The password used to connect the administrative user to the Core.||Yes|
A list displays showing the machines protected by the Rapid Recovery Core. It lists the machines found by line item number, the host display name or IP address, and an ID number for the machine.
A list displays the base and incremental recovery points for that machine. This list includes:
r <recovery_point_ID_number> <path>
This command rolls back the volume image specified by the ID from the Core to the specified path. The path for the restore is the path for the device file descriptor and is not the directory to which it is mounted.
Dell recommends performing the following steps to verify a bare metal restore completed from the command line.
This task is a step in Performing a bare metal restore for Linux machines.
Once you execute a bare metal restore from the command line, you should perform a file system check on the restored volume to ensure the data restored from the recovery point was not corrupted.
This task is a step in Performing a bare metal restore for Linux machines. It is part of the process for Verifying the bare metal restore from the command line.
Perform the task below to perform a file system check on the restored volume.
umount <mount point>
fsck -f <volume>
If the fsck returns clean, the file system is verified.
For example, if the volume path is prod/sda1 and the folder you want to mount to is mnt, then type the following and then press Enter:
mount /dev/sda1 /mnt
