EVA4400-MPIO DSM 3.01-Windows 2003 Cluster

[ssiegmund_1]

I have problem with EVA 4400 and Windows 2003 Cluster. I thing it is MPIO DSM. I could not present a Clusterresource (physical Disk).
In the diskmanager I can display all EVA LUN. I formated the basic disk and they have a driveletter. The hpprutil display none reservation.

Hi,
does it apply to all cluster nodes? because the MSCS is shared nothing conceipt - so only 1 cluster node is owning the disk resource

[ssiegmund_1]

I know, that only one server (the owner) display the LUN. But I have tested with only one Node, because with 4 Nodes, doesnt work. I installed a new cluster and tested with one Node.

so after the EVA presentation the luns are nicely visible on the host only once (because of the MPIO), so you can create/format a partition and assign the drive letter, but you are unable to add them to the MSCS disk resource pls?

[ssiegmund_1]

Yes, that is correct! This my problem!

[IBaltay]

could you check if you have all relevant MSCS/MPIO/OS patches applied (e.g. patch which fix the problem of that MSCS is originaly using the SCSI-2 commands and MPIO SCSI-3)?

[ssiegmund_1]

I have tested without MPIO (only one Path). I have the the same problems. I boot from SAN. The systempartition is available on the same Controller. It is possible the problem?

Do you use the SCSIport or the STORport driver?
The SCSIport does not allow the mapping of the system/boot device and a shared disk on the same adapter.

I thing, I have the solution.
