Flow of storage in Exadata: PHYSICAL DISK -> LUN -> CELL DISK -> GRID DISK -> ASM DISK

Part:1 How to associate the lun details with Physical disk

Flow : PHYSICAL DISK <-> LUN Relations

+ To know all the lun in Exadata

cellcli -e list lun

+ To know all the Hard disk(Grid Disk) lun in Exadata

cellcli -e list lun where disktype = harddisk

+ To know all the flash disk (Smart Scan) lun in Exadata

cellcli -e list lun where disktype = flashdisk

+ To know all the free disk lun in Exadata

cellcli -e list lun where celldisk = null

+ To know Physical Disk in other way

cellcli -e  list physicaldisk
