Just to update the list on this issue - I had trouble forcing the
second/failed drive to be hot spare. I had to delete the whole virtual
disk (VD-0), and recreate RAID-1 from the list of 2 drives (now both are
shown properly). The system booted successfully, and as the system is
online, both drives are blinking - that means they are syncing.

It might be risky to try this, but it worked for me.

Thanks.

Sorry, I meant I cleared it yesterday, not now.

I believe I had that and cleared it. But now, in "Ctrl Mgmt" screen the
tab only navigates between "Factory Default", [X] Enable controller
BIOS, [] Enable Alarm, [X] Enable BIOS Stop on Error, and "VD 0 139392
MB". There is not much to play.

On the controller object see if there is a foreign configuration and if
so select clear. That should make the drive available for a hotspare.

The "Hot Spares" under "VD Mgmt" doesn't have anything for pull-down,
and for that there are no "available operations" thru F2 key. So, I
don't see a way to make it into hot spare list.

Thanks.

Apparently the DDF data on the disk is somehow different then what the
controller is expecting. I'm not sure how this happened but the hotspare
method should fix it.

Interestingly I see in the VD Mgmt screen the "hysical Disks" shows
01:00 which is running and the next one is "Missing", as if there is no
drive found. It is the PD Mgmt screen that shows 01:01 being ready.

If you've gotten into this state then you need to assign the drive as a
hotspare to the existing VD and then it will automatically rebuild.

Hi,

I have a drive pulled out accidentally on my 1950, and the RAID-1 is now
running in degraded mode. I pushed the drive back, and the Megaraid-SAS
BIOS reports the drive is in "ready" state, but I didn't find any way to
force it online and sync with the running drive.

Thanks,
