How to shutdown Exadata Storage Server

It’s necessary to shutdown the cell  when performaing maintenance on the Exadata Storage Server.  It’s also important to verify that taking Exadata Storage server offline will not impact Oracle ASM disk group and database availability depends on the ASM redundancy and mirror copies of data.  Below are the high level of how to shutdown Exadata Storage Server

CellCLI> list griddisk attributes name where asmdeactivationoutcome !='Yes'

If any grid disks are returned (like below), then it’s not safe to take the storage offline

                data_CD_1_ancell05

                data_CD_2_ancell05

                data_CD_3_ancell05

                data_CD_4_ancell05

                data_CD_5_ancell05

                data_CD_6_ancell05

                data_FD_00_ancell05

                data_FD_01_ancell05

                data_FD_02_ancell05A

                data_FD_03_ancell05

                reco_CD_7_ancell05

                reco_CD_8_ancell05

                reco_CD_9_ancell05

                reco_CD_disk10_ancell05

                reco_CD_disk11_ancell05

                reco_CD_disk12_ancell05

Inactivate the grid disks before bring Exadata Storage server offline

CellCLI> alter griddisk all inactive

GridDisk data_CD_1_ancell05 successfully altered

GridDisk data_CD_2_ancell05 successfully altered

GridDisk data_CD_3_ancell05 successfully altered

GridDisk data_CD_4_ancell05 successfully altered

….

….

Cellcli > list griddisk where status != ‘inactive’

If all grid disks are inactive, you can power down the exadata storage server

To power off Exadata Storage Servers
