Cause
Once the snapshot volume is marked invalid, VxVM will not start them because the data in the volume is considered as invalid.
Resolution
There are only two ways to start the snapshot.
1. Try to run ‘vxsnap refresh’ again to refresh the snapshot volume and see if the snapshot volume will become valid again. The exiting data in the snapshot volumes will be replaced with latest data from source volume.
# vxsnap -g
2. Dissociate the snapshots and start them, but the customer will need to do the full resync again if snapshot needs to be taken again.
# vxmend -g
After the snapshot volume is started, please verify the data and see if the data is intact. During the previous failed snapshot operation, the data may be affected. After the data is verified, we can continue working with volume or run backups.
When a snapshot needs to be taken again, a full resynchronization will be required.
