Shut Down the Storage Servers

Perform this procedure for each storage server before you power them off. For more information on this task, refer to the Exadata documentation at:

1. Check for other offline disks.

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

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

2. When a storage server is safe to take offline, inactivate all the grid disks.

   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 you can shut down a storage server without affecting database availability.

4. Shut down the cell.
