This alarm indicates that a DRBD sync is in progress from the peer server to the local server. The local server is not ready to bethe primary DRBD node because its data is not current.
Recovery
Wait for approximately 20 minutes, then check if the DRBD sync has completed. A DRBD sync should take no more than 15 minutes to complete.
If the alarm persists longer than this time interval, call My Oracle Support (MOS) for assistance.
