J.4 Copying Disk Data

Copy the disk data of the original system to the disk of the copy destination system.

To copy the system disk, use the following functions of OS:

Solaris 10: Flash archive
Solaris 11 or later: Unified Archives

Copy the data by using software that provides the cloning function, or by using the function to copy the disk data such as the copy function of storage.

For details, see the manuals of the functions to be used.

Note

Unified Archives

When creating the archives by using the archiveadm create command, specify the --root-only option to exclude storage pools other than the ZFS root pool from the archives.
When mirroring the system disk, the disk label of the system disk of the copy destination must be VTOC. By describing the following parameters in the target element (from <target ...> to </target>) of the manifest file (AI manifest) of the automatic installer that is used when restoring the archives, the disk label of the system disk of the copy destination can be set to VTOC.
```
    <disk whole_disk="true">
        <disk_name name="disk_name" name_type="ctd"/>
        <slice name="0" in_zpool="rpool">
            <size val="slice_size"/>
        </slice>
        <slice name="2">
        </slice>
    </disk>
```
Example) If the disk name of the restore destination of the archives is c0t50000393CC8833B8d0, and the size of the slice s0 for the ZFS root pool is 195284992 sectors
```
<target name="desired">
    <disk whole_disk="true">
        <disk_name name="c0t50000393CC8833B8d0" name_type="ctd"/>
        <slice name="0" in_zpool="rpool">
            <size val="195284992s"/>
        </slice>
        <slice name="2">
        </slice>
    </disk>
    <logical>
    ...
</target>
```
For details on the AI manifest, see the OS manuals such as ai_manifest(4).
