NetVault Bare Metal Recovery physical-to-virtual recovery Troubleshooting

Booting the NetVault Bare Metal Recovery Client from a LiveCD

If you are booting the NetVault Bare Metal Recovery Client from a LiveCD, perform the following procedure. If you are booting the NetVault Bare Metal Recovery Client from a standard VaultOS CD, proceed to Booting the NetVault Bare Metal Recovery Client with the Windows® PE-based Plug-in Offline Client.
The following items are required for this procedure:
•
A LiveCD containing the desired OS.
Note the following important points:
•
The LiveCD must mount the loop-back device to perform backup and restore with NetVault Backup.
•
Some LiveCDs automatically mount all partitions for devices, which can lead to restore failure if the file system is mounted before a backup or restore job. If you boot with a LiveCD, ensure that the file system is unmounted before performing a backup or restore.
•
Some LiveCDs automatically use the swap partition for swap operations, which can lead to restore failure if the swap partition is used before a backup or restore job. If you boot with a LiveCD, ensure that the LiveCD does not use the swap partition before performing a backup or restore.
•
A Rescue device — see Creating a rescue device for use with a LiveCD.
•
A USB port, for a Rescue USB device, that uses the 3.0 protocol or earlier, or a secondary CD-ROM drive, for a Rescue CD, on the target system. If the drive is connected through a USB port, it must use USB 3.0 protocol or earlier.
•
If you are using a Rescue CD, you need two CD-ROM drives on the target system — one for the LiveCD and one for the Rescue CD. If connected through USB ports, the drives must use the USB 3.0 protocol or earlier.
To boot the client, perform the following steps.
1
Insert the LiveCD in the CD-ROM drive — if connected through a USB port, the port must use the 3.0 protocol or earlier — on the target system, and reboot the machine.
2
After the OS starts, plug in the device, 3.0 protocol or earlier, or load the Rescue CD.
Usually, the LiveCD automatically mounts the USB/CD drive and shows an icon on the desktop.
3
If the LiveCD automatically mounted the USB/CD drive, use the “mount -l” command to find the path where the device is mounted.
Example:
# mount -l
...
/dev/sdb1 on /media/disk type ext2 (rw,nosuid,nodev)
4
If the LiveCD does not automatically mount the USB drive, mount it manually:
 
* 
NOTE: Follow the same procedure to use a Rescue CD by mounting a CD instead of a USB device.
a
Use the “ls -l /dev/disk/by-id/usb*” command to find the USB devices on the system.
Example:
# ls -l /dev/disk/by-id/usb*
root 9 2007-09-26 8:16 /dev/disk/by-id/usb-JetFl -> ../../sdb
root 10 2007-09-26 8:16 /dev/disk/by-id/usb-JetFl-part1_-> ../../sdb1
root 10 2007-09-26 8:16 /dev/disk/by-id/usb-JetFl-part2 -> ../../sdb2
b
Mount the first partition on the device.
Example:
# mount /dev/sdb1 /mnt/usb
5
To start drdaemon, run the “vaultdr_client.sh” command.
Example:
# cd /mnt/usb
# sh vaultdr_client.sh
6
If you configured NetVault Bare Metal Recovery to use a port other than the default “10000,” exit the NetVault Bare Metal Recovery Daemon dialog box, and enter the new port number manually.
a
To exit the NetVault Bare Metal Recovery Daemon dialog box, press <Ctrl+C>.
b
At the command prompt, type the following command, and press Enter:
drdaemon -p port_number
where port_number is the port you specified in Adding a NetVault Bare Metal Recovery Client to the Plug-in Server or Editing an existing NetVault Bare Metal Recovery Client.
 
* 
NOTE: If you want to restart NetVault Bare Metal Recovery Daemon from the command prompt without changing the port number, type drdaemon and press Enter.
7
If you want to enable multipath support, type the following at a command prompt, and press Enter:
drdaemon -o mpath
 
* 
NOTE: You can enter the -o mpath and -p port_number options together.

Backing up data with Plug-in Offline Client

The Plug-in Server lets you back up full systems. In addition, the plug-in provides detailed backup capabilities that let you select individual disk partitions for backup. This plug-in includes the following items:
•
OS
•
Applications
•
Specific User Information
From the NetVault Backup Selections page, you can select the following Plug-in Server items for backup:
•
Disk Partitions: All (or individual) partitions can be selected for backup.
•
Mounted Volumes (Linux® and UNIX®): All of which are backed up as individual partitions.
 
* 
NOTE: The Master Boot Record (MBR) and the Partition Table items are backed up automatically when a partition (all or individual) is backed up using the Plug-in Server. Therefore, these items are not available to select for a backup.

Prerequisites for backing up data with Plug-in Offline Client

Before initiating a backup with the Plug-in Server, review the following sections for details on prerequisites that must be met.
 
* 
WARNING:Even if there is no difference between the system devices in a backup and a restore, the order of the disks might be different. If the restored data is started without performing a rename, any data that exists on the disks is lost. To compare the information of physical disk at backup and restore, note the Disk Geometry and Device Size at backup. For more information, see Performing a restore in which Disk Numbers are different from the backup.

Booting the NetVault Bare Metal Recovery Client with Plug-in Offline Client

You must boot the target NetVault Bare Metal Recovery Client with the Plug-in Offline Client to prepare it for the backup. To complete the boot process, review the steps in Booting with Plug-in Offline Client.
