You have been asked by Oracle Support to check the firmware of the hard & flash disks in a storage server. Which cellcli command should you use to get this information?

Question

Options

• Alist celldisk attributes name, deviceName, diskType, physicalFirmware
• Blist cell attributes name, deviceName, diskType, physicalFirmware
• Clist physicaldisk attributes name, deviceName, diskType, physicalFirmware
• Dlist devices attributes name, deviceName, diskType, physicalFirmware

• A
  6% (2)
• B
  3% (1)
• C
  92% (33)

Explanation

Option C is correct because physicaldisk is the CellCLI object type that represents the actual physical hardware - both hard disks (HDD) and flash disks (SSD/flash) - and physicalFirmware is a valid attribute of that object, which is exactly what Oracle Support needs to verify firmware versions.

• A is wrong because celldisk represents the logical disk partitions created on top of physical disks, not the physical hardware itself - it does not expose firmware attributes.
• B is wrong because cell refers to the storage server (cell) as a whole, not individual disks; deviceName and physicalFirmware are not valid cell attributes.
• D is wrong because devices is not a valid CellCLI object type at all - this option is a distractor with invented syntax.

Memory tip: Think "physical problem → physicaldisk" - whenever Oracle Support asks about firmware or hardware-level disk details, the physicaldisk object is the only one that maps directly to the real hardware and exposes attributes like physicalFirmware and diskType (which distinguishes HDD from FlashDisk).
