Cannot install Windows 2008 on a Netapp LUN

The blade is using the M81KR adapter. The LUN appears during boot. I boot up using a virtualDVD-ROM with Win 2008 iso-image. I then unmap the ISO and map the UCS drivers for M81KR for Windows 2008. Then it says the LUN is offline and it let's me online it. But then it still says it is unavailable for install. The message is attached. What am I doing wrong? Using UCM 2.0(1m).

Atle,

When you boot the server, from the KVM go into the BIOS options "F2", go to Boot Options and disable the "EFI" boot option.  Save the settings and then attempt to install Windows.  Let us know the results.

Hello Atle,

Please make sure after you load the drivers, re-map the Windows ISO and click refresh button on the installer screen before selecting the target boot LUN.

Hi ,

From the attachment I understand that there are multipaths to the boot LUN. For installing windows, multipathing should be disabled during installation (to use single path) and same has to be enabled after installation. Please try this.

Re: Cannot install Windows 2008 on a Netapp LUN

hi,

I tried refreshing after mapping the windows ISO. Did not make a difference.

Yes, this is multipathed, because this is  FAS3210 cluster. The question is how to disable the multipathing? So far I have only found how to enable it. Does anyone know? Do we really have to disconnect all FC-cables to the partner? Or is it enough just to disable the cluster?

Re: Cannot install Windows 2008 on a Netapp LUN

I turned off multi-pathing by using portsets (specifying exactly wich ports FCP can use). Sadly, the problem is still there. Is this a version or firmware issue?

New Member

Re: Cannot install Windows 2008 on a Netapp LUN

All the version of UCSM supports the windows 2008 installation.

Please create the boot policy using single path and same policy can be used for windows installation purpose alone.

Then you can change the boot policy which has all the path available.

Re: Cannot install Windows 2008 on a Netapp LUN

Hi,

But I have a SAN-Policy. I just tried to create a new boot policy, but as you can see in the attachment, there is no option to create one using single path. Or am I missing something here?

Cisco Employee

Hello Atle,

You can create single HBA with just primary target information in the boot policy and continue with the installation.

Ok, then I have single-path boot policy, because I have not set up any secondary SAN targets. What can then be wrong?

New Member

Cannot install Windows 2008 on a Netapp LUN

Still a mystery. I checked the local Disk policy and ,

it was set to"no RAID". I then removed the policy, but it still does not help. The local disks are still showing up together with the SAN lun, and I get the same error as before. I checked the BIOS policy (not enabled here), but I cannot see anything there that can change anything.

Cisco Employee

The Local Disk policy only affects the local disks.  This can be set to either Independent, RAID-1 or RAID-0.  If they are installed, they will appear to the OS. 

Sounds like you're attempting a SAN install so the local disk policy is not relevant here.  On the NetApp, what did you set the "LUN Share" on this LUN to?  It should be set to "None".  As long as that's set correctly, and you mount the drivers & Windows OS in the correct sequence as detailed by Padma above, you should be able to install to the LUN.

Which drivers .iso version are you using for the M81KR drivers?

Regards,

Robert

Cannot install Windows 2008 on a Netapp LUN

Hi Robert,

I have not set any LUN sharing, no.

I am using UCS drivers 2.01c

I have been using the correct sequence. I just discovered that it let's me install if I ignore the error message, but it will not boot the OS upon reboot.

The Storage driver for Win2008 R2 is installed as a Storport miniport driver.

Cisco Employee

Post install, did you change the Boot Policy to include all paths?

Robert

New Member

Cannot install Windows 2008 on a Netapp LUN

no, the boot policy has all the time only had Primary path and no secondary path. I will also mention that this is a lab setup with only 1 FI. As described here , I managed to get rid of multi-pathing by introducing portsets on the Netapp storage side. I will double check now if lun sharing is on, but I do not think so and will post soon if it is on.

Hi Atle,

Seen issues in the past with Win2K8 booting from SAN and the server also having local disks installed (as seems to be the case in your setup).

It is also documented in the configuration guide to remove the local disks if performing Boot from SAN:

"If you are creating a boot policy that boots the server from a SAN LUN  and you require reliable SAN boot operations, you must first remove all  local disks from servers associated with a service profile that includes  the boot policy."

http://www.cisco.com/en/US/docs/unified_computing/ucs/sw/gui/config/guide/2.0/b_UCSM_GUI_Configuration_Guide_2_0_chapter_011101.html#task_95B79439BDE0407095DE697F0AA0C950__prereq_999FB59674FD40A5A3E04E9375D9A778

So if you could remove the local disks and see if that improves your situation.

Thanks,

Michael

Unfortunately, it still does not work. The local disks do not appear, but the partitions for the sanlun cannot be set online. See picture. So now I will try creating a new fresh lun and see if that helps.

Just to make it absolutely sure: I am using the WWPN for the Netapp filer. I see that it says "WWN" under boot order.

This is output from the Netapp filer:

1b:   ONLINE   PTP  Fabric

        host address 110001

        portname 50:0a:09:82:9d:64:a1:29  nodename 50:0a:09:80:8d:64:a1:29

        mediatype auto speed auto

0c:   ONLINE   PTP  Fabric

        host address c10001

        portname 50:0a:09:83:9d:64:a1:29  nodename 50:0a:09:80:8d:64:a1:29

I created a new LUN. This time I could make the new unallocated space online, but I got the error this started with: no BIOS support. See picture.

Atle,

When you boot the server, from the KVM go into the BIOS options "F2", go to Boot Options and disable the "EFI" boot option.  Save the settings and then attempt to install Windows.  Let us know the results.

Hi Robert,

There is no EFI option there...

Cisco Employee

Boot Option #6 - Disable it.

New Member

Cannot install Windows 2008 on a Netapp LUN

Sure? Then I cannot boot from Windows ISO-image? I will try and see

New Member

Re: Cannot install Windows 2008 on a Netapp LUN

No luck after disabling it. See picture:

I disabled all boot options regarding EFI also. Message was edited by: Atle Dale

Hi Atle,    

          I also faced the issue with HDS USP storage. But I resolved, I will share the steps followed.

  • Check the Boot Order, weather the correct WWPN of Netapp storage controller port there in the SAN Target.
  • While restarting if it saying BIOS not installed, press Ctrl+H to enable in BIOS
  • Press F6 and see weather the WWPN of Netapp is detected.
  • If all the above are fine means, after u map the driver iso. when the LUN visible, First Delete that LUN and Parttion and then Format it. Again map Windows iso and check

     Hope this will resolve your problem.

Re: Cannot install Windows 2008 on a Netapp LUN

Guys, it is finally working, and I didn't have to try the last suggestion. I believe it was fixed by disabling all EFI boot options. I ignored the error in my post on 14 Feb and created a partition and instaleld on that partition without problems. Now it boots up from Windows 2008 R2 Enterprise. Thanks everybody!
