Console Interface
Continuum systems provide a system console interface through which you can
execute machine management commands. A set of console commands allows you
to quickly control important machine actions.
To access the console command interface, you must connect a terminal to the
console controller. For more information about setting up a console terminal, see
the “Configuring Serial Ports for Terminals and Modems” chapter in the HP-UX
Operating System: Peripherals Configuration (R1001H). For more information about
console commands, see “Solo Components” in Chapter 1, “Getting Started,” in this
manual.
Flash Cards
Continuum Series 400/400-CO system’s primary boot is from a 20-MB PCMCIA
flash card rather than from disk. The root file system and the HP-UX operating
system and kernel do reside on disk, however. The flash card uses the Logical
Interchange Format (LIF) to store the following:
■ primary bootloader (LYNX)
■ secondary bootloader (boot)
■ bootloader configuration file (conf)
For a complete description of flash cards, how they work, and how you update
them, see Chapter 3, “Starting and Stopping the System.”
NOTE
The lifcp, lifinit, lifls, lifrename, and lifrm commands will
not work on the LIF files stored on a flash card. You must use the Stratus
commands to manipulate files on a flash card.
Power Failure Recovery Software
The system supports software logic to provide power failure protection. You can
connect an external uninterruptible power supply (UPS) to your Continuum Series
400 system to take advantage of this capability. You can configure power failure
software logic with the powerdown command. See the powerdown(1M) man page.
For information about configuring the power failure configuration on your
system, see “Dealing with Power Failures” in Chapter 3, “Starting and Stopping
the System.”
