After you hot swap an HDD, the updated HDD metrics fail to appear in the Cisco UCS Manager GUI. Which option is the most likely cause of the problem?

Question

Options

• AThe Cisco UCS Manager gathers hard disk metrics only during a system boot.
• BThe hard disk firmware version is unsupported.
• CThe hard disk failed to initialize.
• DThe hard disk is a member of a RAID-1 array.

• A
  69% (41)
• B
  20% (12)
• C
  7% (4)
• D
  3% (2)

Explanation

Cisco UCS Manager collects hard disk metrics (temperature, health, spin speed, etc.) only at boot time, so a hot-swapped drive won't populate those statistics in the GUI until the next system restart - making A the correct answer. Option B is wrong because an unsupported firmware version would typically trigger an alert or compatibility warning, not simply missing metrics. Option C is wrong because a failed initialization would surface as an error state or absent disk, not silently missing metrics for an otherwise recognized drive. Option D is wrong because RAID membership doesn't suppress metric collection in UCS Manager; RAID drives still report their individual disk statistics.

Memory tip: Think of UCS Manager's disk metrics as a "snapshot at boot" - like a photo taken at startup. Hot-swapping adds a new subject after the photo was taken, so it won't appear until the next picture (reboot).
