how can I import and activate a cluster volume group in a server with no cluster service on it

Hi all,

I have to import and activate a cluster volume group in a server with no cluster service on it. Please can someone help on this issue. I have done vgimport succesffuly but when I do vgchange -c n the command hangs with no result. is there anyway to remove the cluster id from the VGRA to be able to do vgchange -a y on the server with no cluster service on it. thanks for your prompt reply.

Even if the cluster services are not active on the node where you did the vgimport you should still be able to do vgchange -a n and then vgchange -a y to activate.

when I do vgchange -a y it says conflict with configured mode so I need to clear the cluster ID but the vgchange -c n hangs.... any ideas.

Even the man pages say that the vgchange -c n does not need the high availability software to be running but yes you need to run the vgchange -a n first and then vhcgange -c n (give it some time and see if you can see anything in the syslogs)

Maybe the VG was marked as sharable also on the previous node
Ok, try his
vgchange -a n VGName
vgchange -S n VGname
vgchange -c n VGname
vgchange -a y VGname

Thanks a lot, the last reply was correct the disks have write disabled due to replication issues and that's why we have got this problem.
