You are about to replace one memory DIMM in an Exadata storage server and need to power off the affected cell. Which four commands must you execute to safely power off the storage server in your…

Question

Options

• A`crsctl stop cluster -all' on one of the database servers
• BCellCLI> LIST GRIDDISK ATTRIBUTE name WHERE asmdeactivationoutcome != `Yes'
• CCellCLI> ALTER GRIDDISK ALL INACTIVE
• DCellCLI> LIST GRIDDISK WHERE STATUS != `inactive'
• E`shutdown -h now' on the affected cell

• A
  30% (11)
• B
  70% (26)

Explanation

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. 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. -- Verify all grid disks are INACTIVE to allow safe storage server shut down by running the following command: CellCLI> LIST GRIDDISK ATTRIBUTES name, asmmodestatus CellCLI> LIST GRIDDISK If all grid disks are INACTIVE, then the storage server can be shutdown without affecting database availability To stop a server, use the shutdown command. To stop immediately and keep it down, i.e. not reboot, execute: shutdown -h -y now
