You can change an inactive boot environment into an active boot environment. Only one boot environment can be active at a time. The newly activated boot environment becomes the default environment upon reboot.
How to Activate an Existing Boot Environment
1. Use the following command to activate an existing, inactive boot environment:
beadm activate beName
beName is a variable for the name of the boot environment to be activated.
Note the following specifications.
beadm activate beName activates a boot environment by setting the bootable pool property, bootfs, to the value of the ROOT dataset of the boot environment that is being activated.
beadm activate sets the newly activated boot environment as the default in the menu.lst file.
2. Reboot.
The newly activated boot environment is now the default on the x86 GRUB menu or SPARC boot menu.

How to Recreate a ZFS Root Pool and Restore Root Pool Snapshots In this scenario, assume the following conditions:
*ZFS root pool cannot be recovered
*ZFS root pool snapshots are stored on a remote system and are shared over NFS
*The system is booted from an equivalent Solaris release to the root pool version so that the Solaris release and the pool version match. Otherwise, you will need to add the -o version=version-number property option and value when you recreate the root pool in step 4 below.
All steps below are performed on the local system.
1.Boot from CD/DVD or the network.
On a SPARC based system, select one of the following boot methods:
ok boot net -s ok boot cdrom -s If you don't use -s option, you'll need to exit the installation program.
2.Mount the remote snapshot dataset.
For example:
3.Recreate the root pool.
For example:
# zpool create -f -o failmode=continue -R /a -m legacy -o cachefile=/etc/zfs/zpool.cache rpool c1t0d0s0
4.Restore the root pool snapshots.
This step might take some time. For example:
# cat /mnt/rpool.0311 | zfs receive -Fdu rpool Using the -u option means that the restored archive is not mounted when the zfs receive operation completes.
5.Set the bootfs property on the root pool BE.
For example:
# zpool set bootfs=rpool/ROOT/osolBE rpool
6.Install the boot blocks on the new disk.
On a SPARC based system:
# mount -F nfs remote-system:/rpool/snaps /mnt # installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/c1t0d0s0

B: The Network Status notification icon is only displayed on the desktop if you are using NWAM to automatically configure your network.
C: All online (Wireless)
Indicates all manually enabled connections in the enabled network profile are online and that the required number of connections in the enabled profile group (if such a group exists) are online. The required number is the same as those described for the All online (Wired) status.
Note that at least one online connection is wireless.
