2V0-621 Question #52: Real Exam Question with Answer & Explanation
The correct answer is B: The device is in a Permanent Device Loss (PDL) state.. The 'Status: off' field in esxcli storage core device list output is the key indicator that a storage device has entered a Permanent Device Loss (PDL) state.
Question
An administrator runs the command esxcli storage core device list and sees the following output: mpx.vmhba1:C0:T0:L0 Display Name: RAID 5 (mpx.vmhba1:C0:T0:L0) Has Settable Display Name: false SizE. 40960 Device Type: Direct-Access Multipath Plugin: NMP Devfs Path: /vmfs/devices/disks/mpx.vmhba1:C0:T0:L0 Status: off Is Local: true What can be determined by this output?
Options
- AThe device is a being used for vFlash Read Cache.
- BThe device is in a Permanent Device Loss (PDL) state.
- CThe device is a local Solid State Device (SSD).
- DThe device is in an All Paths Down (APD) state.
Explanation
The 'Status: off' field in esxcli storage core device list output is the key indicator that a storage device has entered a Permanent Device Loss (PDL) state.
Common mistakes.
- A. A device configured for vFlash Read Cache is identified by its SSD classification and vFlash configuration association, not by a Status of 'off'.
- C. A Solid State Device would be identified by an 'Is SSD: true' field in the output; no such field appears here, and the mpx naming convention does not indicate SSD status.
- D. An All Paths Down (APD) condition is a transient unknown-loss state where the array has not confirmed permanent loss; APD does not produce a Status of 'off' and is tracked separately from PDL by the Native Multipath Plugin.
