A Hard Drive (HDD) has been hot swapped in a UCS server blade, however, the UCS Manager GUI is not displaying updated metrics about the replacement drive. What action will be required to properly disp

Question

Options

• ARemove and re-insert the server blade HDD controller mezzanine card
• BReboot the Fabric Interconnects
• CReboot the server.
• DUse the CLI, since HDD metrics cannot be displayed with the UCS Manager GUI

• A
  72% (26)
• B
  3% (1)
• C
  17% (6)
• D
  8% (3)

Explanation

When an HDD is hot-swapped in a UCS blade, the storage controller mezzanine card (which interfaces between the drives and UCS Manager) sometimes fails to push updated inventory and metrics for the new drive to the management plane. Removing and re-inserting the mezzanine card forces the CIMC to re-enumerate the storage subsystem and report accurate metrics - without taking the server fully offline.

Why the distractors are wrong:

• B - Rebooting the Fabric Interconnects is a fabric-wide disruptive action that has no bearing on a single blade's internal storage metrics.
• C - A full server reboot would work, but it defeats the purpose of hot-swap (avoiding downtime) and is not the required or recommended action.
• D - UCS Manager GUI can display HDD metrics; the issue is a post-swap refresh problem, not a GUI limitation.

Memory tip: Think of the mezzanine card as the "reporter" - when a new drive arrives via hot-swap, the reporter didn't witness the change, so you need to reseat it to make it re-survey its storage devices and file an updated report with UCS Manager.
