Migrating existing SAN boot images

If you have a Sun host and existing SAN boot images that are controlled by storage controllers, you can migrate these images to image-mode virtual disks (VDisks) that are controlled by the SAN Volume Controller.

1. Shut down the host.
2. Perform 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 SAN Volume Controller.
3. Zone one port of each host bus adapter (HBA) to one of the SAN Volume Controller ports that is associated with the I/O group for the target image-mode VDisk.
4. Perform the following configuration changes on the SAN Volume Controller:
   1. Create an image-mode VDisk 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 SAN Volume Controller port in step 3.
   3. Map the image mode VDisk 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 required. For example, you might map the swap disk to the host with SCSI LUN ID 1.
