If you have an existing partition on a platform that is booting to the external storage device and wish to configure a partition on a different platform to access the same boot volume—for example, a backup partition for recovery purposes in case of the first platform fails—do the following:
Using the Fabric Manager user interface, commission a partition on the other platform, specifying the boot path to the same WWPN and LUN number (targets) as the existing partition. To prevent corruption of data on the LUN on the external storage device, be sure to specify an initial state of Stopped for the partition image.
Since the LUN contains information from the existing partition, Fabric Manager alerts you that user interaction is required.
Access the partition desktop, and choose to only configure the HBA port.
The installation script configures the partition to have boot access to the LUN, but does not overwrite the existing LUN contents.
If desired, verify that the backup partition is configured to access the same boot volume: Using the Fabric Manager user interface, stop the existing partition, start the backup partition, and then access the partition desktop to verify that it is the correct system.
