Verifying a bare metal restore

CAUTION:
To restore the system or root (/) partition or entire operating system, see
metal restore for Linux machines
1. Run the Rapid Recovery
local_mount
utility as root, for example:
sudo local_mount
2. At the Rapid Recovery mount prompt, enter the following command to list the protected machines.
lm
3. When prompted, enter the IP address or hostname of your Rapid Recovery Core server.
4. Enter the logon credentials, that is, the user name and password, for this server.
A list displays showing the machines protected by this Rapid Recovery server. It lists the protected
machines found by line item number, host/IP address, and an ID number for the machine (for example:
7d658e5f-fa08-4600-95f0-5f486bc1b6a4#de0896fd-571a-4cc5-aeed-264d2c3c72f4#f377e145-
dd4d-3ac3-5b15-37ce8f4913ba:2).
5. Enter the following command to list the currently mounted recovery points for the specified machine:
lr <machine_line_item_number>
NOTE:
Note that you can also enter the machine ID number in this command instead of the line item
number.
A list displays that shows the base and incremental recovery points for that machine. This list includes a
line item number, date/timestamp, location of volume, size of recovery point, and an ID number for the
volume that includes a sequence number at the end (for example,
”293cc667-44b4-48ab-91d8-44bc74252a4f:2”), which identifies the recovery point.
6. Enter the following command to select a recovery point to restore:
r <volume_recovery_point_ID_number> <device path>
This command restores 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, not the directory to which it is mounted.
•
You can also specify a line number in the command instead of the recovery point ID number to identify the
recovery point. In that case, you would use the protected machine line number (from the lm output), followed by
the recovery point line number and volume letter, followed by the path, such as, r <machine_line_item_number>
<recovery_point_line_number> <volume_letter> <path>. In this command, <path> is the file descriptor for the
actual volume.
For example, if the
lm
output lists three protected machines, and you enter the
lr
command for
protected machine number
2
, and you want to restore the
23
recovery point volume
b
to the volume
that was mounted to the directory
/dev/sda5,
the command would be:
r2 23 b /dev/sda5
NOTE:
It is possible to restore to / if needed. If performing a Bare Metal Restore using a Live
DVD, it is assumed you want to restore to a different machine. For more information, see
Launching a bare metal restore for Linux
7. When prompted to proceed, enter
y
for Yes.
Once the restore proceeds, a series of messages will display to notify you of the status.
8. Upon a successful restore, the
local_mount
utility will automatically mount and re-attach the kernel
module to the restored volume if the target was previously protected and mounted. If not, you will need to
mount the restored volume to the local disk and then should verify that the files are restored (for example,
you can use the
sudo mount
command and then the
ls
command.)

Verifying a bare metal restore
After you perform a bare metal restore (BMR), you can verify the progress of the restore. When the action
is completed successfully, you can start the restored server. Some troubleshooting steps are included if you
