Backup and Recovery - Oracle Exadata Recipes: A Problem-Solution Approach - page 219

Start by validating your image information on your server by running the imageinfo command:

[root@cm01dbm02 ~]# imageinfo
Kernel version: 2.6.18-238.12.2.0.2.el5 #1 SMP Tue Jun 28 05:21:19 EDT 2011 x86_64
Image version: 11.2.2.4.2.111221
Image activated: 2012-02-11 23:26:55 -0500
Image status: success
System partition on device: /dev/mapper/VGExaDb-LVDbSys1
[root@cm01dbm02 ~]#

■ In this example, the compute node we are restoring is currently available and not in a failed state. In real-world
scenarios in which you need to perform LvM snapshot-based recoveries, it may be likely you will not have access to the
compute node due to failure.

Note

If you have any applications or software currently running and have access to your compute server, you should
shut them down prior to continuing with the next steps.

1. Ensure that your backup is located on an NFS share that the compute node can access.

In the case of the following example, our backup image is located on an NFS share called
172.16.1.200:/exadump/cm01dbm02_bkp/ cm01dbm02.t.bz2 :

[root@cm01dbm02 ~]# ls -l /dump/cm01dbm02_bkp/
total 24157948
-rw-r--r-- 1 root root 24737733538 Jan 20 1993 cm01dbm02.t.bz2
[root@cm01dbm02 ~]# df -h /dump
Filesystem Size Used Avail Use% Mounted on
172.16.1.200:/exadump 14T 6.8T 6.8T 50% /dump
[root@cm01dbm02 ~]#

2. Now, you need to attach your diagnostics image to the ILOM. Transfer

/opt/oracle.SupportTools/diagnostics.iso from any of your other
compute nodes to your workstation:

Macintosh-7:jclarke$ scp root@cm01dbm01:/opt/oracle.SupportTools/diagnostics.iso.
root@cm01dbm01's password:
diagnostics.iso 100% 31MB 923.5KB/s 00:34
Macintosh-7:ch14 jclarke$

3. Enable redirection in the ILOM web console by logging in to the ILOM web console of the

compute node that you wish to restore and navigating to Remote Control - Redirection , as
depicted in Figure 8-14 .
