Troubleshooting

Dealing with a Boot Failure

Here is an example of path number notation:

boot p1 [Enter] attempts to boot from the second path in a list generated by a previous search command.

Supported Boot Paths

SCSI devices are bootable when connected to any SCSI port on the system. Workstations can only boot from the built-in LAN port. The workstation can be booted from the CD ROM drive for software installation.

Intermediate System Loader (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 during the Boot Administration environment.

The ISL environment provides the following capabilities:

Execute user-entered commands to modify boot device paths and boot options in stable storage.

Run off-line diagnostic programs and utilities.

Provide automatic booting of the HP-UX operating system after power-on or reset.
