A: The - of the Active Column indicates that this boot environment is inactive,and hence not bootable.
Note: The values for the Active column are as follows: R - Active on reboot.
N - Active now.
NR - Active now and active on reboot.
"-" - Inactive.
"!" - Unbootable boot environments in a non-global zone are represented by an exclamation point.
D: beadm create
Creates a new boot environment name,beName.
Note: beadm list
Lists information about the existing boot environment,which is be Name,or lists information
for all boot environments if be Name is not provided.
Note: Using beadm Utility (Tasks)
You can use the beadm utility to create and manage snapshots and clones of your boot
environments.
Note the following distinctions relevant to boot environment administration:
*A snapshot is a read-only image of a dataset or boot environment at a given point in time. A snapshot is not bootable.
*A boot environment is a bootable Oracle Solaris environment,consisting of a root dataset and,optionally,other datasets mounted underneath it. Exactly one boot environment can be active at a time.
*A clone of a boot environment is created by copying another boot environment. A clone is bootable.

A subnetwork, or subnet, is a logically visible subdivision of an IP network. The practice of dividing a network into two or more networks is called subnetting.
The routing prefix of an address is written in a form identical to that of the address itself.
This is called the network mask, or netmask, of the address. For example, a specification of the most-significant 18 bits of an IPv4 address, 11111111.11111111.11000000.00000000, is written as 255.255.192.0.

D:zoneadm haltcommand haltsthe specified zones. halt bypasses running the
shutdown scripts inside the zone. It also removes run time resources of the zone.
E:Use: zlogin zone shutdown
to cleanly shutdown the zone by running the shutdown scripts.
Use this procedure to cleanly shut down a zone.
1.Become superuser, or assume the Primary Administrator role.
2. Log in to the zone to be shut down, for example, my-zone, and specify shutdown as the name of the utility and init 0 as the state. global#zlogin my-zone shutdown -y -g0 -i 0

Use the pkg search command to search for packages whose data matches the specified pattern.
Like the pkg contents command, the pkg search command examines the contents of packages. While the pkg contents command returns the contents, the pkg search command returns the names of packages that match the query.
