Troubleshooting
Dealing with a Boot Failure
Answering yes (y) causes the ISL to be loaded from the
specified device. After a short time, the following
prompt appears on the screen:
ISL>
ISL is the program that actually controls the loading of
the operating system. By interacting with ISL, you can
choose to load an alternate version of the HP-UX oper-
ating system.
For example, if the usual kernel (/stand/vmunix) on the
root disk (fwscsi.6.0) has become corrupted, boot the
workstation from the backup kernel (/stand/vmu-
nix.prev) by typing the following at the ISL> prompt:
hpux /stand/vmunix.prev
• To find the location of the bootable operating systems on
the various media in the file system, use the search com-
mand.
