SVM Volumes Built on Slice 2 Fail JumpStart When Used as the Boot Device in a Guest Domain

Bug ID 6687634: If the Sun Volume Manager (SVM) volume is built on top of a disk slice that contains block 0 of the disk, then SVM prevents writing to block 0 of the volume to avoid overwriting the label of the disk.

If an SVM volume built on top of a disk slice that contains block 0 of the disk is exported as a full virtual disk, then a guest domain is unable to write a disk label for that virtual disk, and this prevents the Solaris OS from being installed on such a disk.

Workaround: SVM volumes exported as a virtual disk should not be built on top of a disk slice that contains block 0 of the disk.

A more generic guideline is that slices that start on the first block (block 0) of a physical disk should not be exported (either directly or indirectly) as a virtual disk. Refer to Directly or Indirectly Exporting a Disk Slice in Logical Domains 1.3 Administration Guide.
