I've connected two physical servers with FC (dual port) to an EVA 4400 SAN. Windows Server 2008 R2 is running on the servers. One LUN(diskvolume) is created. This diskvolume should work as a shared storage.
Configured on the SAN:
- Created a vDisk
- Raid 5
- Diskspace is set to 100GB
- Presented for two servers.
When I login to one of my servers and start Server Manager - Storage - Disk Management and Rescan Disks. 4 disks is detected. Why?
I was expected to see one shared disk.
Could it be configuration errors from my side or how do I correct it?
Kind regards,
TL

SolutionProbably because you have not configured/installed any multipathing software... in your case it should be HP MPIO for EVA.

Re: Windows Server 2008 R2 connected to EVA 4400 with FC
1) You see 4 disks because there are 4 paths to the disk. You need to install MPIO multipath driver to take care of that.
2) Two windows severs cannot access the same disk simultaneously, unless you configure them as cluster.

and this is what you need to read
http://bizsupport1.austin.hp.com/bc/docs/support/SupportManual/c01387306/c01387306.pdf
and of course you need to have them configured in a cluster if want to present same LUN to both of them

It worked like magic.
I gave you both top score.
