re-adding a hotswapped drive to a Supermicro m/b

I hot-swapped a drive in a Supermicro chassis (D-1541) and the drive light next to it is blinking yellow now and inaccessible to vSphere.  How do I get that to go back to normal?

I suspect it's rebuilding the drive after the failure, It'll take a while i'm guessing.

Have you checked the homepage of the server to see what it's currently doing?

Thanks

This is a datastore on a vSphere host and it lists the drive as Inactive.  Since the SM box also has a yellow blinking light next to that drive, I'm assuming that the m/b isn't telling the hypervisor that it is available.  Hm.  I have the PDF hardware manual for that m/b somewhere.  I'll look that up and see what it says.

Well that was underwhelming.  The user manual doesn't mention this condition at all.  I'll try to find the manual on the case, since the light technically is on the case.

Without knowing what controller / motherboard you have it would just be guesswork. Can you reboot and watch POST to see what is in it?

Sorry, was about to post the details.  The server bundle I bought is a Supermicro Mini Tower Intel Xeon D-1541 box.  It has a SC721 case on it.  

Unfortunately this server has other drives in it with VMs on them so rebooting isn't an option at the moment.

Can only guess at the controller although vSphere should show it.

You can try storcli to see if it is a MegaRAID controller in it but knowing the CPU and the metal box isn't much help. Can't be Intel chipset RAID so MegaRAID is likely. Unfortunately though you need a reboot before you you can run the diags according to https://kb.vmware.com/s/article/2146429 (unless it's already installed or the older  megacli is there). If you pulled the wrong one then you could import it although unlikely to do that with 4 disks in a row.

I presume you've pulled the replacement disk out again?

Hi Andy,

It does show it but lists it as 'inactive'.  No raid controllers in this setup.  
No, hadn't reseated it yet.  Was scrambling to get the other VMs that were on it up and running but that has settled down now.  That's a good suggestion.  I'm cloning a VM right now but that should be wrapped up in a few minutes.  I want to make sure I only do one thing at a time in case something else goes south.

Ok, this is awkward.  Got a flashlight and looked at the symbols next to the lights; the yellow one just indicates disk activity.  It is just a coincidence that there are 4 lights in a vertical column next to the drives.  So this is back to being a software issue with the vSphere Web client.

Thanks for all the good ideas!  

(Note to self: make darn sure you know which drives are which before pulling one.)

In this case I have myself to blame for not properly documenting the placement of the drives.  My bad.
Thanks again!
