Troubleshooting : Recovery Node and PN Disk Space Alerts : A0903
  
A0903
Message: The Recovery Node disk space allocated for volume(s) DriveLetter of RNName is over 90% used. The RN will be created, however you may wish to increase the amount of disk space allocated to each named above volume of that RN.
Cause: Initial vdisk size allocated for a volume on the PN is inadequate because of the growing data on PN in the corresponding volume. In this case, the onQ Manager does not update the RN.
Solution: Resize the vdisk 15–20% over what is currently being used.
