Migrating existing SAN boot images

If you have an Oracle host and existing SAN boot images that are controlled by storage controllers, you can migrate these images to image-mode volumes that are controlled by the system.

1. Shut down the host.
2. Complete the following configuration changes on the storage controller:
   1. Remove all the image-to-host mappings from the storage controller.
   2. Map the existing SAN boot image and any other disks that you want to present to the system.
3. Zone one port of each host bus adapter (HBA) to one of the system ports that is associated with the I/O group for the target image-mode volume.
4. Complete the following configuration changes on the system:
   1. Create an image-mode volume for the managed disk (MDisk) that contains the SAN boot image.
      Use the MDisk unique identifier to specify the correct MDisk.
   2. Create a host object and assign it to the HBA port that you zoned to system port in step #svc_sunmigratesanboot_2bxlh1/migzonehba.
   3. Map the image mode volume to the host.
      For example, you might map the swap disk to the host with SCSI LUN ID 0.
   4. Map the swap disk to the host, if necessary.
      For example, you might map the swap disk to the host with SCSI LUN ID 1.
5. Restart the host.
