LVM - Quorum

Hi all
Just a question about quorum.
I am running AIX 5.3

Rootvg has 2 PV - not mirrored. quorum is switched on.
What happens when one disk fails?, can i replace the disk and bring the entire VG back up. with all the data intact. knowing that the VG will be unavailable until i replace the disk.

Thank you in advance

VOTEQUORUM_QDISK_REGISTER(3)			    Corosync Cluster Engine Programmer's Manual 		      VOTEQUORUM_QDISK_REGISTER(3)

NAME
votequorum_qdisk_register - Registers a new quorum device SYNOPSIS
#include <corosync/votequorum.h> int votequorum_qdisk_register(votequorum_handle_t handle, char * name, unsigned int votes); DESCRIPTION
The votequorum_qdisk_register is used to register a new quorum device. A quorum device is an external way of adding votes to a small clus- ter. The quorum device is, in effect, a pseudo node in the cluster that provide votes based on some external device, usually a shared disk partition or perhaps a network router. This call creates the device but does not mark it active. votequorum_qdisk_poll must be called for the votes to be included in the quorum calculation. Note that it is the responsibility of the quorum device subsystem (not provided as part of votequorum) to keep all nodes informed of the quorum device status. RETURN VALUE
This call returns the CS_OK value if successful, otherwise an error is returned. ERRORS
The errors are undocumented. SEE ALSO
