Monitoring Exadata Storage Cells - Oracle Exadata Recipes: A Problem-Solution Approach - page 365

In addition, for Alert 2_1 the severity is marked info and the alertAction is Informational . This would
indicate that the Exadata DMA would likely not need to perform any specific tasks to rectify the condition. If we run
the same list alerthistory command for Alert 1 , you can see that Oracle provides corrective action measures in the
alertAction attribute:
CellCLI> list alerthistory 1 detail
name: 1
alertMessage: "Factory defaults restored for Adapter 0"
alertSequenceID: 1
alertShortName: Hardware
alertType: Stateless

severity: info
alertAction: "If this change is unintentional, contact Oracle Support."

Listing Your alerthistory Using dcli
Exadata DMAs typically monitor storage cell alerts for each cell in the storage grid. Use the following dcli command
to list your alert history for each of your storage cells:
[oracle@cm01dbm01 ~]$ dcli -g ./cell_group cellcli -e list alerthistory

To report on your critical storage cell alerts, use the following dcli/cellcli command:
[oracle@cm01dbm01 ~]$ dcli -g ./cell_group cellcli -e list alerthistory where severity='critical'
[oracle@cm01dbm01 ~]$
