Restoring Application Operating Environments on Enterprise Partition Platforms

The ClearPath Forward fabric does not support bare-metal restore of partitions. If the original partition no longer exists, you commission a new partition image, and then recover the environment of the previous partition into the new partition. When restoring your operating environment, ensure that you do not include the EFI system partition (if it was backed up) as part of the restore process. For more information on backup and restore tools, see Examples of Tools for Backing Up and Restoring Application Operating Environments.

To restore the Windows or Linux operating environment containing your applications

  1. Commission a new partition on the desired platform using the same blueprint that was used to create the original partition, or a similar blueprint.

    The new partition must be the same operating system type as the original partition, but may be different in size.

  2. Use the backup image captured from the original partition to recover the saved operating system and application environment onto the new partition.

  3. For the Linux operating environment, if you previously made changes to files on the Linux /boot/efi partition of the original partition image (for example, operating system kernel changes, initrd and  efi configuration file changes, or driver updates), you may need to reapply the changes on the new partition image after the restore process.

  4. Verify the network configuration for your restored partition:

    • If your partition participated in a secure fabric, manually reassociated the partition with the secure fabric. For more information on associating a partition after commissioning, refer to Associating a PEPP Partition with a Secure Fabric After Commissioning.

    • If you restored your backup to a replacement partition image with a different platform number or partition number than the original partition, be sure to modify the IP addresses of the partition (on the FM LAN, the IP-LAN secure fabric, other secure fabrics, and so on) from what was captured during the backup to the current values used by Fabric Manager for the replacement partition image. Refer to the summary page of the partition in Fabric Manager for the IP addresses assigned to the partition image on the various LANs and secure fabrics. If your application environment has the old IP addresses configured within it, be sure to reconfigure so that your application can communicate properly with the new partition.

    • If the backup was restored to a different physical environment—for example, to a different physical platform or NIC port configuration—be sure to examine the operating system settings for all network interfaces, and, if necessary, reconfigure for the new environment.
