LSI Megaraid alarm - clearing hotspare

Question

I have several Supermicro servers with LSI Megaraid controllers, 9266-8i. One recently lost a drive; I replaced it as usual, but it is still beeping on reboot. It is set up as RAID 10 + hotspare.

MegaCli64 -AdpEventLog -GetEvents -f events.log -aALL && cat events.log shows me:

Event Description: Global Hot Spare created on PD 08(e0xfc/s0) (global,rev)
Event Description: Reminder: Potential non-optimal configuration due to drive PD
                    08(e0xfc/s0) commissioned as emergency spare

Since the beep pattern is 1 second on, 3 seconds off, which is the code for "SPEAKER_HOTSPARE_ENTRY - A hot spare drive has completed the rebuild process and has been brought into the array", I assume this is the root of the problem. I have updated to the latest firmware, since the release notes mentioned the "Potential non-optimal configuration" message, but no change.

Anyone have an idea on how to clear this?

There is no functional impact. To prevent the message from appearing in the system event logs:

• Open MegaRAID Storage Manager.
• Select Tools --> Monitor Configure Alerts.
• Select Change Individual Events.
• Highlight event ID 406.
• Deselect the System log check box.

Solution 2

I have LSI controller, RAID 10 with four disks. One disk went bad, hot-swap replace -> automatically set hot spare flag on new disk and got same warning as above. Turn machine off, physically remove replacement disk, separately did quick format to unset RAID participation, replaced disk and turned machine on. Automatically found disk and started rebuild into RAID with unset hot spare flag.

Trick seems to be finding time when machine can be shut down for cold-swap with fresh disk.

I'm using this but I really hate to disable a valid warning, would love to have a real fix instead. No more hardware RAID for me, ZFS from now on
