zfs snapshot [-r] [-o property=value] ... filesystem@snapname|volume@snapname

Creates a snapshot with the given name. All previous modifications by successful system calls to the file system are part of the snapshot. See the “Snapshots” section for details.

-r

Recursively create snapshots of all descendent datasets. Snapshots are taken atomically, so that all recursive snapshots correspond to the same moment in time.

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.

B: Setting the default route on Solaris is easy. If you are trying to just set the route temporarily you can use the route command:

Route add default

Example:

Route add default 192.168.1.1

Note: Route command manipulates the kernel routing tables. Routing is the process of forwarding a packet from one computer to another. It is based on the IP address in the IP packet header and netmask.

F: If you want the route to be persisted when you reboot the system, you will need to set the route in the /etc/defaultrouter file.

/etc/defaultrouter

Example:

Echo 192.168.1.1 > /etc/defaultrouter

D: According to line /etc/security

F: According to line /export/home

Not E: According to line IGNORE dirmtime

Note: In default mode, the bart compare command, as shown in the following example, checks all the files installed on the system, with the exception of modified directory timestamps (dirmtime):

CHECK all

IGNORE dirmtime

Note 2: The Basic Audit Reporting Tool (BART) feature of Oracle Solaris enables you to comprehensively validate systems by performing file-level checks of a system over time. By creating BART manifests, you can easily and reliably gather information about the components of the software stack that is installed on deployed systems.

BART is a useful tool for integrity management on one system or on a network of systems.
