Problem initializing MD3000
2 servers connected via 1 sas cable each to MD3000
1st is win 2003 r2 sp2 x86 standart
installed everything from DELL_MD3000-RCD_A07 (latest for win2003)
full install
everything ok
2nd is win 2008 x64 standart
installed everything from DELL_MD3000-RCD_A07 (latest for win2008)
full install
cannot see the drive!
when I enter Disk Management it proposes to initialize the disk with 2 choises MBR or GPT
neither of them fit
for example I choose MBR & I get error "Incorrect function"
In event viewer I can see that:
VDS fails to write boot code on a disk during clean operation. Error code: 80070001@02070008
Also in Win 2003 in device manager in disk drives I have DELL MD3000 SCSI Disk Device & DELL MD3000 Multi-Path Disk Device
& in Win 2008 I have only DELL MD3000 SCSI Disk Device
why??

Server 1 has Dell SAS 5/E with sas 2 ports
&
Server 2 has Dell SAS 5/E with sas 2 ports
1 port of each server is connected to MD3000
Server 1 & Server 2 are in host group.
This host group is mapped to one virtual disk.
???

You do have 2 different virtual disks, right? One for each server?
Servers cannot share disk space on a SAN unless you cluster the servers. If you 'force' it, you will guaranteed run into data/filesystem corruption. This could be within seconds, minutes, hours or days, but it's guaranteed.
Assuming this requirement is met, do you have 1 raid controller with 2 ports (and each server connecting to it's own port) or 2 controllers (each with 1 or 2 ports) and each server to a different controller?
The reason I ask is that a virtual disk has an owner (raid controller) of the virtual disk. If your server is connected to one raid controller only and the disk is owned by the other controller, you may not be able to see the disk.

hey vainkop,
as Dev Mgr stated, if you are trying to access the same virtual disk (VD) from 2 separate hosts that are not clustered together, you are likely to run into data corruption issues. The device is equipped to handle data from a single host at a time. clustering them will allow the hosts to make sure that they do not conflict with each other. Is there any specific reason that you have configured it this way?
I presume that you are able to see the VD from the w2k3 host and have initialized it. Are you trying to initialize it a second time from the w2k8 box?

Dear mrokkam & others, I do have "specific reasons that I have configured it this way".

You destroy your host group, give the disk to 1 server, and make a Windows share and then map the other server to that share.
