Originating Source IP	Node IP where the alarm was raised.
Sequence Number	Number which indicates the order in which alarms were raised.

In Table 1, the indicated variables are as follows:

• <DG> is the DSG this cluster belongs to.

2   Procedure

Perform the following steps:

1. Check DS storage engine traces to see if a restore file is missing by logging into the System Controller (SC) where the restore was launched, and execute the following command:
   # grep -i restore /var/log/messages

   For more information about logs, refer to CUDB Node Logging Events, Reference [2].

   Execute again the restore after fixing logged problems. Being this alarm autocease, it should be cleared once a correct restore is done.

2. If the alarm does not cease, contact the next level of maintenance support. Further actions are outside the scope of this Operating Instruction.
