vxdg import fails with VxVM vxdg ERROR V-5-1-587

We have a two node cluster system. Service was running on one of the systems properly. The service was failed over to the other system. The failover failed. Now I am not able to start the service on the first system as well. The import fails with the following error.
VxVM vxdg ERROR V-5-1-587 Disk group omcdg: import failed: No valid disk found containing disk group

Also, the command "vxdisk -o alldgs list" does not list and vxvm disks.
Please help in this scenario. Very urgently required for one of our systems.

Re: vxdg import fails with VxVM vxdg ERROR V-5-1-587

Then you are using the wrong command.. vxdg import will not work.

What you have sir are LVM managed disks.. so you'll need vgimport and vgchange to do the trick.

Does your cluster not have any documentation ? Is this a production cluster or a non-production one that you as a novice are allowed to manage?

Re: vxdg import fails with VxVM vxdg ERROR V-5-1-587

I am not a complete novice for Service guard as such. This is not a production cluster. Also I am sure abt the disks, they were configured as VXVM disks. I had only configured them before. The system was running fine since a time period of 5-6 monhts. The service was running properly on both the nodes. What we tried was that a node was built again from scratch to simulate a hardware failure. Then we tried to run the package on this node. The package didnt run on this node. Then I tried to run it on the node that was working fine before. But it didnt start. We have 4 more cluster pairs in out environment and they are all on VXVM disks and running fine.

My main concern is that only how the disks became LVM disks?

Re: vxdg import fails with VxVM vxdg ERROR V-5-1-587

Anuraag, apologies I thought you are new to your system.

Other things you can check:

1.) The disks that you listed -- are you sure they are the same disks that you claim *were* VxVM before?

2) If you are, then someone or something initialized them as LVM disks.

3) Try to see if the VGIDs of all the disks are all the same. If they are..trace from your other node(s) where they also show up with the same VGID and check what LVM VG theynow belong to and chase up on your peers, your SAN Admins, etc. on what happened, if there are changes.

4) A distant possibility -- you are in a SAN Twilight Zone...

Re: vxdg import fails with VxVM vxdg ERROR V-5-1-587

Hi Nelson,
I can list the scenario that led to this situation.
1) Node1 and Node2 were working fine in cluster with the shared file system as VXVM disks.
2) Service was now running on node2.
3) We wanted to try recovery procedures so we created node1 from scratch.
4) Now we failed over the cluster package from node2 to node1.
5) Node1 couldnt start the package. Then we checked the listing and the disks were now shown as LVM.
6) We tried to start the package back on node2 and the package didnt start.

Then somewhere in between.. there was "something" that changed them...

Continue with your hunt... look at the VGIDs of those disks..
