isl must be brought up in interactive mode to use the operations and options of
hpux. To do this, simply
enter a character during the 10 second interval allowed by
pdc. pdc then asks if the primary boot path is
acceptable. Answering yes (
Y) is usually appropriate.
pdc then loads isl and isl interactively prompts
for commands. The following lines show the boot prompt, the
Y response, subsequent boot messages, and
finally the Initial System Loader (ISL) prompt that are sent to the display terminal:
Boot from primary boot path (Y or N)?> y
Interact with IPL (Y or N)?> y
Booting...

Although all of the operations and options of
hpux can be used from isl interactively, they can also be
executed from an
autoexecute file. In the examples below, all user input follows the
ISL> prompt on
the same line. Subsequent text is resultant messages from the ISL.
Default Boot
Entering
hpux initiates the default boot sequence. The boot path read from pdc is 8.0.0, the manager
associated with the device at that path is
disc, the minor number, in this case derived from the
autoex-
ecute
file, is 4 specifying section 4 of the disk, and the object file name is
/stand/vmunix.
ISL> hpux
Boot
: disc3(44.3.0;0)/stand/vmunix
3288076 + 323584 + 405312 start 0x11f3e8
Booting Another Kernel
In this example, hpux initiates a boot operation where the name of the object file is
vmunix.new .
ISL> hpux vmunix.new
Boot
: disc3(44.3.0;0)/stand/vmunix.new
3288076 + 323584 + 405312 start 0x11f3e8
Booting From Another Section
In this example (shown for backward compatibility), a kernel is booted from another section of the root
disk. For example, suppose kernel development takes place under
/mnt/azure/root.port
which
happens to reside in its own section, section 3 of the root disk. By specifying a minor number of
3 in the
above example, the object file
sys.azure/S800/vmunix
is loaded from /mnt/azure/root.port
.
ISL> hpux (;3)sys.azure/S800/vmunix
Boot
: disc(8.0.0;0x3)sys.azure/S800/vmunix
966616+397312+409688 start 0x6c50
Booting From Another Disk
Only the hardware path and file name are specified in this example. All other values are boot defaults.
The object file comes from the file system on another disk.
ISL> hpux (52.5.0.0)/stand/vmunix
Boot
: disc(52.5.0.0)/stand/vmunix
966616+397312+409688 start 0x6c50
Booting From LAN
This example shows how to boot a cluster client from the LAN. Though this example specifies a devicefile,
you can also use default boot, as shown in a previous example. For a boot operation other than default
boot, the file name must be specified and can be no longer than 11 characters. Booting to isl from a local
disk then requesting an image to be loaded from the LAN is not supported.
