Booting to VxVM MMB prevents the VxVM configuration daemon (vxconfigd) from being
started during system initialization. When booted to VxVM MMB, the system will be in single
user mode with only the root volume mounted.
Several conditions will prevent the system from being booted in a normal way. This section
provides symptoms that accompany such conditions and procedures that may be used to repair
the system to once again allow normal operation.
Missing LABEL File
A missing LIF LABEL file will prevent successful bootup of the system. During system bootup,
the LABEL file is used to determine the offset and length of the root, stand and swap/dump
volumes before the VxVM configuration daemon may be started.
Symptoms of a missing LABEL file during bootup
Welcome to HP-UX for IA64
setting hpux path(\EFI\HPUX)...
type 'fs[x]:' where x is your bootdisk (0, 1, 2...)
type 'hpux' to start hpux bootloader
Shell> fs2:
fs2:\> hpux
Could not open :LABEL file
Could not read VxVM LABEL file from LIF FS.
Restoring the LABEL file
Boot to VxVM Maintenance Mode Boot. This will use the /stand/rootconf file to
locate the root volume, bypassing making use of the LABEL file.
Boot the system to VxVM maintenance mode:
fs2:\> hpux -vm
VxVM maintenance mode
