[Linux-cluster] iscsi and clusterd volume group

[nirmal tom]

hi,
as per the usage guide , i activated the c or clustered bit for the volume 
group, rac.Now it is shown to my kernel or system.So, the iscsi target fails 
and whatever command i gave with respect to lvm it simly reponds skipping as 
u see below

[root at server ~]# vgchange -a y rac
  Skipping clustered volume group rac
[root at server ~]# vgchange -c n rac
  Skipping clustered volume group rac
[root at server ~]# vgremove rac
  Skipping clustered volume group rac
[root at server ~]# vgchange --clustered n rac
  Skipping clustered volume group rac
ered volume group rac
[root at server ~]# vgchange --available e y rac
  Volume group "y" not found
  Skipping clustered volume group rac

how to set the clustered bit to turn off? or to make it avialabel as usual

thanks for any response

regards,
Nirmal Tom.
