PDC Commands
Table 3
is a list of PDC commands available. These commands vary somewhat on
different systems and are updated on a regular basis, so check IT Resource Center (itrc.hp.com) for updates.

| TIME | Reads or sets the real time clock in GMT. |
| WARNINGS | Display any warning messages that may have resulted from the previous PDC self-test execution. |
Initial System Loader
The Initial System Loader (ISL) is run after the
PDC. You would normally just run an “autoboot” sequence from ISL;
however, you could run a number of commands from the ISL prompt.
Picking up where we left off in the previous example, I chose to BOot off device p0 and interact with IPL, as shown in the following example:
Main Menu: Enter command or menu > bo p0
BCH Directed Boot Path: 0/0/0/3/0.6
Do you wish to stop at the ISL prompt prior to booting? (y/n) >> y

HELP Help Facility
LS List ISL utilities
AUTOBOOT Set or clear autoboot flag in stable storage
AUTOSEARCH Set or clear autosearch flag in stable storage
PRIMPATH Modify primary boot path in stable storage
ALTPATH Modify alternate boot path in stable storage
CONSPATH Modify system console path in stable storage
DISPLAY Display boot and console paths in stable storage
LSAUTOFL List contents of autoboot file
FASTSIZE Sets or displays FASTSIZE
800SUPPORT Boots the s800 Support Kernel from the boot device
700SUPPORT Boot the s700 Support Kernel from the boot device
READNVM Displays contents of one word of NVM
READSS Displays contents of one word of stable storage
LSBATCH List contents of batch file
BATCH Execute commands in batch file
LSEST List contents of EST (Extended Self Test) file
EST Execute commands in EST (Extended Self Test) file
EXIT Return to the Boot Console Handler
Enter 'LS' to see a list of the ISL utilities.
Issuing a ? produces a list of ISL commands that I could issue. Issuing the DISPLAY command shows the boot and console paths, and LS lists the ISL utilities available, as shown in the following example:
ISL> display
Autoboot is ON (enabled)
Autosearch is OFF (disabled)
Primary boot path is 0/0/0/3/0.100663296.0.0.0.0.0
Primary boot path is (hex) 0/0/0/3/0.6000000.0.0.0.0.0
Alternate boot path is 0/0/0/0/0.0.0.0.0.0.0
Alternate boot path is (hex) 0/0/0/0/0.0.0.0.0.0.0
System console path is 0/0/0/0/0/0/0/0.0.0.0.0.0.0
System console path is (hex) 0/0/0/0/0/0/0/0.0.0.0.0.0.0

DISPLAY produced the information we expected based on what we saw PDC produce in the previous section. LS produced two utilities available to us: ODE and HPUX (ODE is the Offline Diagnostics Environment.) The following example shows listing the ODE utilities available on the system by running ODE, the HELP command to see what commands are available, and LS to list the ODE utilities:
ISL> ode

ODE Help
Basic Commands
--------------
HELP -- Prints detailed information to the screen, when "help <command>"
or "help <var>" is typed
LS -- List modules available on boot medium
<Module_Name> -- Load and initialize a module by typing its name
(For more help, type "help module_name")
MENU -- Launch ODE's ease-of-use interface
RUN -- Run a module (after setting desired environment variables)
Control-Y|Control-C -- Abort an ODE command; pause a module run
RESUME -- Restart a paused module
DISPLOG -- After running a module, display contents of a log
EXIT -- Return to next higher level prompt
Environmental Variables
-----------------------
SHOWSTATE -- Display the value of the following environment variables:
LOOP -- Run a test this many times
ERRPRINT [ON|OFF] -- Print low-level error messages to console
(primarily for manufacturing use)
ERRNUM [ON|OFF] -- Print one-line, numbered errors to the console
Continue ([y]/n)? y
ERRPAUSE [ON|OFF] -- Pause module upon error detection
ERRONLY [ON|OFF] -- Print ONLY error messages; disable non-error
and isolation message printing
INFOPRINT [ON|OFF] -- Print informational messages to the console
ISOPRINT [ON|OFF] -- Print fault isolation messages to the console
ISOPAUSE [ON|OFF] -- Pause module when isolation message is generated
LOGSIZE -- Set the size of a message log
DEFAULT -- Reset environment variables to default state

When I ran ODE and issued LS, the three utilities at the end of the example were listed. I always load ODE
as a part of system installations to help in the event of a possible
system hardware problem that an HP Customer Engineer may need to come
onsite to diagnose.
Next, I'll proceed with the boot process by running the HPUX utility.
