Explanation

Note on order of the create commands: # cellcli -e alter cell : : This CELLCLI command startup all services CREATE CELLDISK ALL--This CELLCLI command automatically creates celldisks on all available logical unit numbers (LUNs). CREATE GRIDDISK ALL PREFIX=prefix--This CELLCLI command automatically creates grid disks on all available Exadata cell disks. Each Exadata storage cell has 12 disks.- One physical disk is called LUN and is also called cell disk.- A grid disk is part of a cell disk. So the Cell disk must be created before the grid disk. The "calibrate" command, which is part of the Exadata storage "cellcli" interface, is used to test the capabilites of the underlinying components of Exadata storage. The throughput and IOPS of both the drives and Flash modules can be tested at any point to see if they are performing up to calibrate" command should be executed after celldisk and grid disk are created.
