Installing a ZFS Root File System (Oracle Solaris Flash Archive Installation)

Starting in the Solaris 10 10/09 release, you can create a flash archive on a system that is running a UFS root file system or a ZFS root file system. A flash archive of a ZFS root pool contains the entire pool hierarchy, except for the swap and dump volumes, and any excluded datasets. The swap and dump volumes are created when the flash archive is installed. You can use the flash archive installation method as follows:

Review the following limitations before you consider installing a system with a ZFS flash archive:

After a master system is installed with or upgraded to at least the Solaris 10 10/09 release, you can create a ZFS flash archive to be used to install a target system. The basic process follows:

The following archive options are supported for installing a ZFS root pool with a flash archive:

After a ZFS flash archive is installed, the system is configured as follows:

Example 5-2 Installing a System with a ZFS Flash Archive

After the master system is installed or upgraded to at least the Solaris 10 10/09 release, create a flash archive of the ZFS root pool. For example:

# flarcreate -n zfsBE zfs10upflar
Full Flash
Checking integrity...
Integrity OK.
Running precreation scripts...
Precreation scripts done.
Determining the size of the archive...
The archive will be approximately 4.94GB.
Creating the archive...
Archive creation complete.
Running postcreation scripts...
Postcreation scripts done.

Running pre-exit scripts...
Pre-exit scripts done.

On the system that will be used as the installation server, create a JumpStart profile as you would to install any system. For example, the following profile is used to install the zfs10upflar archive.

install_type flash_install
archive_location nfs system:/export/jump/zfs10upflar
partitioning explicit
pool rpool auto auto auto mirror c0t1d0s0 c0t0d0s0
