booting from raw character device
In booting from a raw device, the manager specified only has a character interface, which might cause
problems if the block size is incorrect.
isl not present, please hit system RESET button to continue
An unsuccessful boot operation has overlaid isl in memory. It is impossible to return control to
isl.
short read
The specified object file is internally inconsistent; it is not long enough.
would overlay
Loading the specified object file would overlay
hpux.
Configuration
cannot add path, error number
An unknown error has occurred in adding the hardware path to the I/O tree. The internal error
number is given. Contact your HP Field Representative.
driver does not exist
The manager specified is not configured into hpux.
driver is not a logical device manager
The manager named is not that of a logical device manager and cannot be used for direct I/O opera-
tions.
error rewinding device
An error was encountered attempting to rewind a device.
error skipping file
An error was encountered attempting to forward-space a tape device.
negative skip count
The skip count, if specified, must be greater than or equal to zero.
no major number
The specified manager has no entry in the block or character device switch tables.
path incompatible with another path
Multiple incompatible hardware paths have been specified.
path long
The hardware path specified contains too many components for the specified manager.
path short
The hardware path specified contains too few components for the specified manager.
table full
Too many devices have been specified to hpux.
EXAMPLES
As a preface to the examples which follow, here is a brief overview of HP-UX system boot-up sequences.
Automatic Boot
Automatic boot processes on various HP-UX systems follow similar general sequences. When power is
applied to the HP-UX system processor, or the system Reset button is pressed, processor-dependent code
(firmware) is executed to verify hardware and general system integrity (see pdc(1M)). After checking the
hardware, pdc gives the user the option to override the autoboot sequence by pressing any key. At that
point, a message resembling the following usually appears on the console.
Processor is starting the autoboot process.
To discontinue, press any key within 10 seconds.
If no keyboard activity is detected, pdc commences the autoboot sequence by loading isl (see isl(1M))
and transferring control to it. Since an autoboot sequence is occurring, isl finds and executes the
autoexecute file which, on an HP-UX system, requests that hpux be run with appropriate arguments.
Messages similar to the following are displayed by isl on the console:
10 seconds expired.
