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.

STMF – Manages transactions, such as context and resources for Small Computer System Interface (SCSI) command execution, and tracking logical unit and port providers. STMF also handles logical unit mappings, allocating memory, recovering failed operations, enumeration, and other necessary functions of an I/O stack.

STMF is controlled by stmfadm, and stmfadm is the majority of the commands you will be using to administer COMSTAR (COmmon Multiprotocl Scsi TARget).

Install the packages you need for COMSTAR with iSCSI and reboot:

# pfexec pkg install storage-server

# pfexec pkg install SUNWiscsit

# shutdown -y -i6 -g0

Note: You can set up and configure a COMSTAR Internet SCSI (iSCSI) target and make it available over the network. The iSCSI features can work over a normal Internet connection (such as Ethernet) using the standard iSCSI protocol. The iSCSI protocol also provides naming and discovery services, authentication services using CHAP and RADIUS, and centralized management through iSNS.

The COMSTAR target mode framework runs as the stmf service. By default, the service is disabled. You must enable the service to use COMSTAR functionality. You can identify the service with the svcs command. If you have not rebooted the server since installing the group/feature/storage-server package, the service might not be enabled correctly.

'ipadm show-addr' displays all the configured addresses on the system.

Example:

# ipadm show-addr
