5. At the HPUX.EFI interface (the HP-UX Boot Loader prompt, HPUX>) enter the
boot -is vmunix command to boot HP-UX (the /stand/vmunix kernel) in
single-user (-is) mode. If you are booting from a different kernel file into
single-user mode substitute the other file’s name for vmunix. The -is option is
what specifies single-user mode.

6. If you are accessing the system console through the management processor and
you are no longer using it, exit the console and service processor interfaces.
To exit the EFI environment type ^B (Control-B); this exits the nPartition console
and returns to the service processor Main Menu. To exit the service processor, type
X at the Main Menu.
Booting into LVM (or VxVM) Maintenance Mode
The procedure for booting HP-UX into LVM Maintenance Mode is the same as for
booting into single user mode (See “Booting HP-UX Into Single-User Mode on HP
Integrity Servers” (page 54) for details), except use the -lm boot option instead of the
-is boot option:
HPUX> boot -lm vmunix
For VxVM Maintenance Mode use:
HPUX> boot -vm vmunix
