Oracle VM Server for x86 version 2.1

The root storage repository will be the device mounted on /OVS on the server. All extended storage
repositories will be mounted as /OVS/UUID and defined in /etc/ovs/repostories.

Oracle VM Server for x86 version 2.2

You may list all configured repositories on the server using the following command:

/opt/ovs-agent-latest/utils/repos.py –l

The command will produce output similar to the following:

[ * ] 450c66f5-6e10-4ca8-b086-c1413236f1f2 => /dev/sda3

[ ] c0e18fd7-c162-4183-836b-c883f9b1b41c => mickey:/ovm

The output indicates that there are 2 repositories configured on the server and the active root storage
repository is identified by the asterisk (*).

Regardless of the version of Oracle VM Server being used, you will see that the repository UUID is linked to a
device or NFS mount point on the server. Given that you are likely to be performing system recovery to
different disks, this link will be broken and will require further attention before it is usable. Those steps are
described below.

System Recovery of Oracle VM Server (dom0)

The steps to perform system recovery of an Oracle VM Server (dom0) using SBAdmin are very similar to the steps
for any other Linux system. Refer to the

SBAdmin Linux System Recovery Guide

for additional details. However,

the following considerations deserve mention because they are specific to Oracle VM Server and dom0 systems:

Creating Boot Media

In order to perform system recovery of an Oracle VM Server (dom0), you will need a SBAdmin system backup
(discussed above) and SBAdmin boot media. The boot media is used to provide the system you wish to recover
with an environment and interface to perform the recovery. Boot media types supported for performing
recovery of dom0 are CDROM and hard disk. Performing network boot (PXE) of a dom0 is not supported.

For more information on creating SBAdmin boot media please refer to the

SBAdmin Linux System Recovery

Guide

.

Migrating Storage Repositories (Version 2)

Assuming you are not performing recovery to the same disks that were used at the time of the backup, the
storage repositories on the server may require additional maintenance after the system first boots following the
system recovery. This is because the device names used by the repositories may have changed or the UDEV
UUID linked to the device is not the same as found in the ovs-agent database.

The first step is to reconfigure the repositories on the server:
