Dell PowerVault MD3460 Storage Arrays redundancy

we have MD3460 enclosure attached to two servers and configured  with two disk dynamic pool and both virtual disks mapped to one host.
is there any way to map those virtual disks to the other host to be accessible in case the fist host get down ?

if not what is the best way to allow those virtual disks to be accessible by the two hosts for load balancing or fail over .

What you describe is a failover cluster. The details of implementing failover clustering depends on the type of connection, the workload being clustered, and the OS being run.
Paul MacDonaldDirector, Information SystemsCommented:
To extend Cliff's answer, it also depends on how the disks are set up.  Microsoft clustering requires the drive space to be provisioned as LUNs, rather than volumes (SAN vs NAS).  

So to answer your question, yes, it's possible.

10 Tips to Protect Your Business from Ransomware

Did you know that ransomware is the most widespread, destructive malware in the world today? It accounts for 39% of all security breaches, with ransomware gangsters projected to make $11.5B in profits from online extortion by 2019.

I've already create a host group for bother server and add LUNs for the two DDP under it
Mohamed HammadAuthor Commented:
one more action i've done now , the partition is appear on both servers right now but when create a folder from server1 to this partition it didn't appear at server2 on the same partition

I don't k ow why you already accepted an answer if you didn't read and understand the answers given.

You can't "just" attach a disk to two windows servers. NTFS us not a shared file system. At *best* you get the results you are sring (discrepencies.) But it can be a lot worse. You can get data loss and significant corruption.

To do what you want, you *need* to set up a failover cluster. And ad I said above, how you do that depends on many factors. A SQL cluster uses different steps than a file server cluster. Which is different yet than a hyper-v cluster.

I've asked an administrator to step in and reset the question.  I think my answer was accepted prematurely.

Thanks Cliff for your note .

Actually we will make file server cluster do you have full guide for this ?

Cliff GaliherCommented:
paulmacd posted a guide for that.
Mohamed HammadAuthor Commented:
by follow this guide it didn't show if i have a storage that already contain files and need to create a cluster for it .

it seems that i need to have an empty storage and start the process from scratch .

is there anyway to have this cluster with a storage already contain data ?
Paul MacDonaldDirector, Information SystemsCommented:
You can create the cluster using shared storage that already contains data, if the shared storage is an existing LUN; the cluster itself doesn't care.  Just skip the steps where you create the new shared storage and instead point to the existing storage you want to use.
