mount: 0506-324 Cannot mount /dev/oradata_lv on /oradata: There is a request to a device or address that does not exist.

I have a two node cluster sharing a Storwize V7000 between then. Volume groups "oradata_vg" and "oralogs_vg" were created on the shared LUNs.

I then mounted file systesms /ordata and /oralogs on the volume groups. I was also able to manualy switchover the file system between the two nodes of the cluster.

But now when I tried to mount /oradata on the first node I got the "mount: 0506-324" error message.

On doing an lspv on the node I noticed that the volume group was not active. I did an varyonvg on that volume, but that failed.

I noticed that the volume group was active on the second node, so I did a varoffvg of the volume groups. I then did a varyonvg of the volume groups on the first node. I was then able to mount the file systems
