Cannot boot to
initial system
loader (ISL)
• Console
messages
indicating
problems
booting from
the primary
or alternate
boot path.
• Console
messages and
prompt indicating
you are at ISL.
1. Use EFI shell commands to
verify I/O and presence of
valid devices.
2. Use EFI boot manager
boot
info
command to determine
boot related information.
3. Check system event log
(SEL) for detailed message(s).
4. Remove I/O cards to
eliminate them as cause of
problem.
• Boot path

error
• SCSI cable not
connected from
channel A to drive
cage
• Hard disk drive
