Gen8 2.5" HDD in the ODD bay discussion

Recommended Posts

OK – I’ve put together some instructions for the board.  Note that (1) these have not been tested, although I did use this approach on my MicroServer successfully, and (2) by using these instructions you agree that I take no responsibility (nor liability in perpetuity) for the effect your usage of these instructions may have on your data – you’re on your own and if it all goes horribly wrong, please do not be surprised!  I would strongly recommend you do not have any data on the server at this stage…

 

Before you start, you need the following:

  • A copy of Windows installed (Windows Server 2008 R2 or later will do, any edition – this may work on Windows Server 2008 too, but earlier editions have a different method that these instructions do not cover) on the MicroServer and booting successfully.  Note that if you've installed Windows onto a drive in the ODD, you will need to physically remove all the hard drives from the trays (just pulling them out 1/2" will do to be able to boot the server from the ODD), otherwise the MicroServer will try and boot from one of the non-ODD hard drives first.  There is no way to specifically prioritize the ODD drive above the others.
  • Insert the MicroSD (or USB key) into the internal slot before you boot.  If you are unable to boot, go into the Setup Utility (BIOS) and ensure that the boot order has USB set to lowest priority.
  • Boot the MicroServer into your copy of Windows.
  • Mount the Windows setup ISO.  Windows Server 2012 and later has an ISO mounter built in - but if you're running another version, you can use something like Virtual CloneDrive, available at http://www.slysoft.com/en/virtual-clonedrive.html Make a note of the drive letter.
  • Go to "My Computer" or similar in Explorer and make a note of the drive letter and size of your MicroSD card or USB key.  If you cannot see it here, then there are a couple of reasons - if the drive is not formatted properly you may be able to get it working by consulting the Disk Management MMC snap-in and formatting it there.  Also, if you didn't use Intelligent Provisioning, and you're using the MicroSD card, you may not have the right drivers installed - in which case go and grab them from the HP site and install.

Now for the fun stuff:

 

  1. Start an elevated command prompt. Start | type cmd | Right-click cmd (top of menu) | Run as Administrator.  Note that you can just run a command prompt if you have UAC turned off (standard for Windows Server installs).
  2. Next, run Diskpart to prepare the disk.  Enter each of the commands in order.  Be very careful as a mistake here can have serious consequences! Note that the question mark “?” below should be replaced with the disk number of the drive you are using:

diskpart

list disk

select disk ?

clean

create partition primary

select partition 1

active

format fs=ntfs quick

label=”<YOUR LABEL GOES HERE>”

exit

 

  1. Now copy the boot sector to the MicroSD card or USB key.  You should still be in the command prompt window.  Replace $ below with the drive letter of your mounted ISO image, and ? with the drive letter of your newly formatted MicroSD card or USB key.

C:\Windows\system32>$:

$:\>cd boot

$:\boot>bootsect /nt60 ?:

   Target volumes will be updated with BOOTMGR compatible bootcode.

   Bootcode was successfully updated on all targeted volumes.

$:\boot>exit

Note that if you get an error message here, normally you can fix this by closing any open windows with that drive and try again.  You could also use the /force switch for bootsect if you prefer.

 

  1. Now we need to copy critical boot files to the MicroSD card/USB key.  Using Windows Explorer, copy the following directories and files to the MicroSD card/USB key:

bootmgr (file)

bootmgr.efi (file)

boot (directory)

efi (directory)

Nothing else is required.

 

  1. Delete the file "bcd" from the directory "boot" on the MicroSD card/USB Key - we'll be recreating it shortly.
  1. Start another elevated command prompt. Start | type cmd | Right-click cmd (top of menu) | Run as Administrator.  Note that you can just run a command prompt if you have UAC turned off (standard for Windows Server installs).
  1. Replace ? in the following BCDEDIT commands with the current drive letter of your MicroSD card or USB key:

 

bcdedit /createstore ?:\boot\bcd

bcdedit /store ?:\boot\bcd /create {bootmgr}

bcdedit /store ?:\boot\bcd /set {bootmgr} device boot

bcdedit /store ?:\boot\bcd /timeout 30

bcdedit /store ?:\boot\bcd /create /d "<Your OS Name Here>" /application osloader

That returns a new GUID that you should plug into this next command:

bcdedit /store ?:\boot\bcd /default {<GUID>}

For the next commands where I've denoted *:, replace it with the drive letter of your current Windows boot drive.  So if I'm booted on my MicroServer into the OS I am looking to boot from my MicroSD/USB Key and it's C:, that's what you need to enter here.  It doesn't matter what the drive will be when you boot - it matters what the OS you're currently executing the bcdedit command sees!

bcdedit /store ?:\boot\bcd /set {default} device partition=*:

bcdedit /store ?:\boot\bcd /set {default} path \windows\system32\boot\winload.exe

bcdedit /store ?:\boot\bcd /set {default} osdevice partition=*:

bcdedit /store ?:\boot\bcd /set {default} systemroot \Windows

bcdedit /store ?:\boot\bcd /set {default} detecthal yes

bcdedit /store ?:\boot\bcd /set {default} nx optin

bcdedit /store ?:\boot\bcd /displayorder {default} /addlast

Finally...  If you want to run Hyper-V (and have a capable edition of Windows Server, and have installed the role), you must enter the following command (otherwise the Hypervisor won't start and Hyper-V Manager will throw up all sorts of errors):

bcdedit /store ?:\boot\bcd /set hypervisorlaunchtype auto

 

  1. Boot into the Setup Utility (BIOS) on your MicroServer and prioritize USB boot as the first item (MicroSD comes under the USB boot order too).  I have not been able to find a way to prioritize within the USB boot devices.  Therefore, you will need to remove all other storage devices from the USB2 ports (the two USB3 ports on the back of the server are fine as they aren't seen by the BIOS and aren't active until you get into a compatible OS).
  1. OK - your MicroSD card or USB key should be all setup.  At this point you can install drives into the drive trays and you should be good.

I welcome comments from my fellow board members.

 

I hope this is helpful!

 

 

Very NICE TheBiggerMan!!  Thanks for the great detail!! +1

Things become a little more manageable in SATA legacy mode, you will then see 2 controllers (the second one of these containing only the ODD port) and can configure the system to boot from the SDD. This really isn't ideal, specially when using an SSD...

 

My G8 hasnt arrived yet but I want to do something simaler - 4 x main bays as individual drives so I can use Linux mdadm for software RAID (as it allows HDD spin-down, but the hardware controller doesnt) and the 5th mobo port for the SSD in the ODD space.

 

I'm not really up on hardware, but why is SATA legacy mode not ideal?

Hi all new to the gen8 and wonder if I can get some info....

 

Inside the case there appears to be a spare sata port on MB and a spare power socket on the top of case, question is could this be used to fit a SSD?

 

I've posted pic in the gallery if it helps.

 

Thanks again

I responded to your question in the other thread. You really shouldn't cross post with the same question in multiple threads.

Anyone know if we can order this "small metal bracket" as a replacement part? 

I finally received my 9.5mm Blu-ray burner and I'd hate to think of duct tape as the only mounting option.

 

Fyi, here's the one I went with:  Panasonic/Matshita UJ-262:$(KGrHqF,!pEE63Yi!ovFBO3,v5kQvQ~~60_35.J

 

 

Btw, terrific threads.... thanks to all.  Looking forward to contributing some feedback once I receive my E3-1265LV2 later this afternoon.

 

You can see the sub-components for most HP parts using HP Partsurfer.  Specifically for the optional optical drive in the MicroServer

http://partsurfer.hp.com/Search.aspx?SearchText=652241-B21

 

My guess is the last item (532475-001) would be the bracket required but not positive. 

 

I ended up ordering the drive itself - hoping to get the cable which is a sub-part (http://partsurfer.hp.com/ShowPhoto.aspx?partnumber=683358-001)

 

 

I ordered this caddy: http://www.newmodeus.com/shop/index.php?main_page=product_info&cPath=2_27&products_id=220

I picked up a HP 9.5" DVD so I could get a look at the bracket;

t6cu.jpg
It has the part number 469607 Rev B stamped on it.
I have taken some measurements and will try to make a suitable copy;

This is a common bracket for servers, but does not work with the MSG8;

The problem there is that legacy mode is not great for SSDs, namely because it has no support for TRIM. The drive will not only operate slower, but could also affect the lifespan of the drive.

OK - I got my drive caddy and the brackets and cables:

 

Again the Drive Caddy I used is: http://www.newmodeus.com/shop/index.php?main_page=product_info&cPath=2_27&products_id=220

Although some of the others might work - just look for 9.5" ideally with a flat face (some laptop units my have a curved face which might fit but would look goofy) and the holes on the back for the bracket - should be standard.

 

You can go to HP partsurfer for the sub-components: http://partsurfer.hp.com/Search.aspx?SearchText=652241-B21

I still believe based on the description that 532475-001 is the bracket.  As schoondoggy noted the stamped numbering is not related to the HP part #, this is from the supplier making the part for us and doesn't do us much good.  Confident 532475-001 is the one you would need.

 

Oddly enough the CD drive came with 3 cables 2 of them are identical as far as the connections and include a single connector that goes into the back of the drive caddy (smaller scsi connection then the drive itself) and 2 pigtails off of the drive side connector that go to the SATA-ODD port on the MOBO and the floppy power connection at the top of the unit.  The partsurfer link lists 683358-001 that is one of them that came with my drive.  Mine also came with a 2nd cable that would also work 667526-002 it appears the only difference is slightly different lenghts on the pigtails and cable color. 

 

So

You can go to HP partsurfer for the sub-components: http://partsurfer.hp.com/Search.aspx?SearchText=652241-B21

Bracket: 532475-001  (not 100% but thats the one listed as slimline so pretty confident)

Cable: 683358-001

+ drive caddy like the one I mentioned and you'd be all set.

 

Of course you could also do it on the cheap and just keep the blank faceplate, use a standard sata cable + a Y adapter for the molex connection found at the top of the unit with a cable that will break out a SATA power connection.  Secure the drive with 3m adhesive and your all set.  This is how I had it temped in before the gear arrived.
