Installation guide

encapsulation is provided in the document Logical Storage
Manager.
LSM provides a virtual disk that enables you to store and replicate data
without physical boundaries. LSM is composed of physical devices and
logical entities to offer you a mechanism for transparently and dynamically
storing and retrieving files and file systems across devices and in multiple
copies.
If you perform an Advanced Installation and select the LSM subsets, the
following line that enables LSM is automatically placed in your target
configuration file:
pseudo-device lsm 1
When the /usr/sbin/doconfig runs during installation, LSM is built
into the kernel.
However, if you install the LSM subsets after installation with the setld
utility, you must add LSM to the kernel by following these steps:
1. Run the /usr/sbin/doconfig program without any options, as
described in Section 5.4.2.
2. Select the LSM kernel option from the KERNEL OPTIONS menu to
add LSM to the target configuration file and build a new kernel.
3. To enable LSM, you boot the new kernel, as described in Section 5.4.2.
5.6.7.6 Ethernet ARP
If your system uses Ethernet Address Resolution Protocol (ARP) hardware,
the /usr/sbin/doconfig program includes the following entry during
initial system configuration. This entry must be present in the
configuration file:
pseudo-device ether
5.6.7.7 Gateway Screen
If you set your system up as a router and you plan to use the gateway
screen feature, add the following line to your system configuration file:
pseudo-device gwscreen
For more information on the gateway screen, see the screend(8) reference
page.
