A: ZFS can automatically share file systems by setting the sharenfs property. Using this property, you do not have to modify the /etc/dfs/dfstab file when a new file system is shared. The sharenfs property is a comma-separated list of options to pass to the share command. The value on is an alias for the default share options, which provides read/write permissions to anyone. The value off indicates that the file system is not managed by ZFS and can be shared through traditional means, such as the /etc/dfs/dfstab file. All file systems whose sharenfs property is not off are shared during boot.

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.

zonep2vchk

- check a global zone's configuration for physical to virtual migration into non-global zone

The zonep2vchk utility is used to evaluate a global zone's configuration before the process of physical-to-virtual (p2v) migration into a non-global zone.

The p2v process involves archiving a global zone (source), and then installing a non-global zone (target) using that archive

Zonep2vchk serves two functions. First, it can be used to report issues on the source which might prevent a successful p2v migration. Second, it can output a template zonecfg, which can be used to assist in configuring the non-global zone target.

Zonep2vchk can be executed on a Solaris 10 or later global zone. To execute on Solaris 10, copy the zonep2vchkutility to the Solaris 10 source global zone.

When run on Solaris 10, a target release of S11 can be specified, which will check for p2v into a Solaris 10 Branded zone.
