Node: node2
Resource: DIMM-1
Severity: Critical
Indication Time: Fri Dec 22 04:54:10 2023
Suppress: false
Acknowledge: false
Probable Cause: The DIMM has reached end of life, which is leading to
memory errors.
Possible Effect: Memory issues can lead to a catastrophic system panic
which can lead to data downtime on the node.
Corrective Actions: 1. Contact technical support to obtain a new DIMM of the same specification.
2. If possible, perform a takeover of this node and bring the node down for maintenance.
3. Refer to the "DIMM replacement guide for your given hardware platform" to replace the DIMM.
4. Bring the storage system online.
