Displaying PIM Information The pim command allows you to display the most recent PIM information for the specified fault type. To display PIM information for a specific fault, from the Service Menu type the following at the prompt: Service Menu: Enter command > pim processor_number Enter You can use pim in the following ways: pim - gives all processors/all fault types pim processor_number - HPMC information on given processor pim processor_number fault_type - fault type information on given processor Stable Storage Stable storage is nonvolatile memory associated with each PA-RISC processor module. Stable storage is used by the processor (CPU) to store D device path information D the state of the boot flags D HPMC error information D operating system initialization data ISL Environment The ISL environment provides the means to load the operating system (HP-UX) environment. The ISL environment also provides an offline platform to execute diagnostic and utility programs from a boot device when HP-UX does not load. The ISL program is the first program loaded into main memory from an external media (LAN, disk, or tape) and launched by the initial program loader (IPL) routine from the Boot Administration environment. The ISL environment provides the following capabilities: D Execute user-entered commands to modify boot device paths and boot options in stable storage. D Run offline diagnostic programs and utilities. D Provide automatic booting of the HP-UX O/S after power-on or reset. Boot Console 9-13

Displaying PIM Information
The
pim
command allows you to display the most recent PIM information for the
specified fault type. To display PIM information for a specific fault, from the Service
Menu type the following at the prompt:
Service Menu: Enter command >
pim
processor_number
Enter
You can use
pim
in the following ways:
pim
– gives all processors/all fault types
pim
processor_number
– HPMC information on given processor
pim
processor_number fault_type
– fault type information on given processor
Stable Storage
Stable storage is nonvolatile memory associated with each PA-RISC processor mod-
ule. Stable storage is used by the processor (CPU) to store
D
device path information
D
the state of the boot flags
D
HPMC error information
D
operating system initialization data
ISL Environment
The ISL environment provides the means to load the operating system (HP-UX) en-
vironment. The ISL environment also provides an offline platform to execute diag-
nostic and utility programs from a boot device when HP-UX does not load.
The ISL program is the first program loaded into main memory from an external
media (LAN, disk, or tape) and launched by the initial program loader (IPL) routine
from the Boot Administration environment.
The ISL environment provides the following capabilities:
D
Execute user-entered commands to modify boot device paths and boot options
in stable storage.
D
Run offline diagnostic programs and utilities.
D
Provide automatic booting of the HP-UX O/S after power-on or reset.
