Could Win2003 see Win2008 Cloned Lun?
2010-02-08 09:39 PM
IHAC will setup a Hyper-V environment on NetApp filer (FCP-SAN). the VHD will be stored on NetApp filer Luns (of coz, the original luns may be CSV).
They will use SMHV to do quick snapshot.
they have a backup server (win2003) and are requested to backup VMs to tape. Now my question is if window2003(+SDW) could connect those cloned win2008 luns which store VHD? then they could backup those VHD files to tape directly but maybe once time per week.
Thanks and Best Regards!

I did a testing in my lab.
by SDW6.x , Win2003 could see win2008 luns which store VHD. but I am not sure if it's official support.
the original lun type is as following:
fas3020b*> lun show -v /vol/hyperv/cluster/hyperv.lun
/vol/hyperv/cluster/hyperv.lun 50.0g (53694627840) (r/w, online, mapped)
Comment: " "
Space Reservation: enabled
Multiprotocol Type: hyper_v
when I checked the disk information
it include two partiations. one is big and with 129MB offset and 2nd is very small (just 256KB) and with 17KB offset. Why?
I also try to connect a lun whose luntype is windows_2008. It could also be connected by SDW 6.x. but msinfo32 found the offset is 1MB. According TR-3733-1209 (Page40):
"For Windows Server 2008 R2 (including Hyper-V), enter the following at the prompt: windows_2008"
What's the difference btw lun type windows_2008 and Hyper-V?
Of coz, I still need the official answer if win2003 could see win2008 Hyper-V luns.
