  1. Controller shows degraded status as below:
cluster::> system controller show
Controller Name            System ID      Serial Number        Model    Status
------------------------- ------------- -----------------    -------- -----------
cluster-01                512345785     701234567892         FAS9000  degraded
cluster-02                512345787     701234567893         FAS9000  ok

  1. The following health alert is logged:
cluster::> system health alert show
Node: cluster-01
Resource: DIMM-15
Severity: Critical
Indication Time: Thu Aug 26 04:20:47 2021
Suppress: false
Acknowledge: false
Probable Cause: The DIMM has degraded, 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.
