Cause

The root partition file system is full and therefor the OVF properties are not saved (/opt/vmware/etc/vami/ovfEnv.xml)

Resolution

1. Power off the impacted vIDM node
2. Create a Backup/Snapshot
3. Boot the affected vIDM node into single user mode, refer KB 375672 to enter single User Mode.
   • This can be impacting multiple servers if this is a vIDM cluster.  You may need to clean up the space on each server individually.
4. Browse through /var/log directory you can find enormous "messages" files.
5. Deleting the file it will give you an error "This is in Read Only Mode" as the partition is mounted as "Read-Only" Mode
6. Run below command to mount with Read, Write Mode.
   
   mount -o remount,rw /
   
   
7. Now you should be able to delete the messages file
8. Reboot the appliance
