ALM-0x02000009 Hard Disk Prewarning (Disk, Minor Alarm)


Alarm message:

The [arg1] disk arg2 predictive failure (SN: arg3, BN: arg4).

From iBMC V316, the CPU and disk alarms will also include the SN and BOM code and the mainboard and memory alarms will also include the BOM code.

This alarm is generated when the number of hard disk errors reached the prewarning threshold.

If arg2 is DISKA, DISKB, DISKC, or DISKD, this alarm is generated for the rear hard disk of a V2 or V3 server. For details about the slot information of the hard disks on a V3 server, see "Removing a Hard Disk" in the user guide of the server you use.

  • The number of hard disk SMART errors detected exceeds the threshold.
  • The NVMe remaining service life is about to expire.


  1. When this alarm is generated, server operation remains unaffected. Replace the faulty hard disk when convenient. Then, check whether the alarm is cleared.

    • If yes, no further action is required.

    • If no, go to 2.
