Windows 2008 clusters
We have a md3000i and it works great. I have one problem with a windows 2008 cluster. I try and give one node in the cluster a lun from the md3000i and it will see the lun as offline. I can't bring it online or format the new lun. I am not trying to use it as a shared lun in the cluster but as a local drive. Does it have to do with SCSI-3 Persistent Reservation that is required by windows 2008? Does the md3000i support SCSI-3 Persistent Reservation? Thanks for any advice.

And now you want to add an additonal LUN from the MD3000i to a single host, so you've assigned to LUN to the individual host in the MD3000i interface and not the group ?
Is this a correct interpretation of the question ?

It works. The T610 is just base W2k08 Enterprise, no service packs. MD3000i is at the latest firmware version. I created single lun and mapped it the single host I created. Then used the iSCSI initiator in Windows to connect. Then opened Disk Administrator. It showed the disk in "offline" .. I right clicked brought it online, then initialized, then formatted and worked fine.
What firmware version is your MD3000i at ?

Pretty sure that will be the issue. Looks like a planned maintenance window is in your future. Stock up on Mt Dew and Doritos and get those things up to date :-) Let me know how it goes.
And thanks for the kudos, trying to do the best we can.

Just a thought...You did install the latest version of the MD Storage Manager (or at least the one for Gen1) on your Windows 2008 box right? You need to perform a "Host" or "Full" install to make sure that the multi-pathing drivers are installed correctly. You should be able to find the older version of the RCD also on support.dell.com

I'm trying to understand if I miss something or if my MD3000i does not (still) support Persistent Reservation
Please have a lokk at the following link to understand my problem:
http://blogs.technet.com/askcore/archive/2009/04/15/windows-2008-failover-cluster-validation-fails-on-validate-scsi-3-persistent-reservation.aspx
Please help me, I need to understand if I have to change my virtualization solution (e.g. ESXi)
Thanks

Check your firmware level of the md3000i. You will need Generation 2 to support w2008 on the md3000i. Beware if you update to Gen2 firmware you can not roll back to Gen1. Also if you upgrade to Gen 2 you will loose support for w2000 system attaching to the md3000i. I think that is what caused my problem. I am unable to update to Gen2 at this time as we still have some w2000 servers.

I yet have the latest 2nd generation firmware and I'm going to use Windows 2008 x64.
I hope to receive an answer from a Dell technician because I really can't find a solution.
I've read a lot of documentation but "Persistent Reservation" seems to be something unknown.

Are you following the instructions as per the Installation Guide here: http://support.dell.com/support/edocs/systems/clusters/SE600Wi/en/index.htm ?
Dell's clustering documentation is available here
