Shut Down the Exadata Storage Servers

Perform this procedure for each Exadata Storage Server before you power them off. For more information on this task, see the Exadata documentation at:

1. Run the following command to check if there are any offline disks:

   CellCLI > LIST GRIDDISK ATTRIBUTES name WHERE asmdeactivationoutcome != 'Yes'
   

   If any grid disks are returned, then it is not safe to take Exadata Storage Server offline, because proper Oracle ASM disk group redundancy will not be maintained. Taking Exadata Storage Server offline when one or more grid disks are in this state will cause Oracle ASM to dismount the affected disk group, causing the databases to shut down abruptly.

2. Inactivate all the grid disks when Exadata Storage Server is safe to take offline.

   CellCLI> ALTER GRIDDISK ALL INACTIVE
   

   This command completes after all disks are inactive and offline.

3. Verify that all grid disks are INACTIVE.

   CellCLI> LIST GRIDDISK WHERE STATUS != 'inactive'
   

   If all grid disks are INACTIVE, then Exadata Storage Server can be shut down without affecting database availability.

4. Shut down the cell.
