Backing up and Restore the VIOS to one or more DVDs

1. Backing up the VIOS to one or more DVDs
   You can back up the Virtual I/O Server (VIOS) base code, applied fix packs, custom device drivers to support disk subsystems, and some user-defined metadata to DVD.
   To back up the VIOS to one or more DVDs, complete the following steps. Only DVD-RAM media can be used to back up the VIOS.
   Note: Vendor disk drives might support burning to additional disk types, such as CD-RW and DVD-R. See the documentation for your drive to determine which disk types are supported.
   
   
   1.    Assign an optical drive to the VIOS virtual server.
   2.    Obtain the device name by entering the following command from the VIOS command line:
   lsdev -type optical
   If the device is in the Defined state, enter the following command from the VIOS command line:
   cfgdev -dev dev
   3.    Run the backupios command with the -cd option from the VIOS command line. Specify the path to the device. For example:
   backupios -cd /dev/cd0
   Note: If the VIOS does not fit on one DVD, the backupios command provides instructions for disk replacement and removal until all the volumes have been created.
   This command creates one or more bootable DVDs that you can use to restore the VIOS.
   4.    If you plan to restore the VIOS to a different host from which it was backed up, back up the user-defined virtual devices.

   You can restore the Virtual I/O Server (VIOS) base code, applied fix packs, custom device drivers to support disk subsystems, and some user-defined metadata from one or more DVDs.

   To restore the VIOS from one or more DVDs, complete the following steps:

   1. Specify the VIOS virtual server to boot from the DVD by using the bootlist command from the VIOS command line. Alternatively, you can change the bootlist in the System Management Services (SMS).
   2. Insert the DVD into the optical drive.
   3. From the SMS menu, select to install from the optical drive.
   4. Follow the installation steps according to the system prompts.
   5. If you restored the VIOS to a different host from which it was backed up, restore the user-defined virtual devices.
