Hi

check this doc

LVM Maintainance Mode:
The boot/root logical volumes are the only logical volumes that are in a known place when your LVM configuration data has been lost. Maintenance mode is useful on such systems if a standard boot has failed due to LVM configuration problems. You must resolve the LVM configuration problem and then reboot.




CAUTION: When you boot your system in maintenance mode, do not activate the root volume group and do not change to multi-user mode (for example, by specifying /sbin/init 2). If you do, you might corrupt the root file system.
When you have repaired or restored the LVM configuration information, reboot the system using the reboot command with the -n option. This avoids overwriting your disk-based repairs with the old information still stored in memory buffers.

/usr/sbin/reboot -n

Maintaince mode is used mostly for reapir LVM structure for vg00
Mostly for recreating the LIF headers

If you need to boot a system into single-user mode, for example to make sure no one else logs on when you boot the system to do maintenance work:

Booting into Single user mode is for Maintainance activity. In this mode, we are able to mount / and /stand FS, hence we could start our trobleshooting on FS corruption, starting of daemons, password issue, login issues, etc.

You might find this doc as good for your trobleshooting purpose and to understand the booting issue
