You must replace the battery on the disk controller in three Exadata storage servers and must power off the affected storage servers. Which two commands must you execute to safely power off the storage servers in an X5 Database Machine? 

Answer options:

A. ‘shutdown -h now’ on the affected storage servers
B. CellCLI> LIST GRIDDISK WHERE STATUS != ‘inactive’
C. CellCLI > LIST GRIDDISK ATTRIBUTES name WHERE asmdeactivationoutcome != ‘Yes’
D. ‘crsctl stop cluster –all’ on one of the database servers
E. CellCLI> ALTER GRIDDISK ALL INACTIVE

CE

C: Step 1: Run the following command to check if there are 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 intact. E: Step 2: Inactivate all the grid disks when Oracle Exadata Storage Server is safe to take offline using the following command: CellCLI> ALTER GRIDDISK ALL INACTIVE Taking the 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.
