Using the same LUN to a different server
I just wanted to know to have a LUN to be presented on a different server.
Server A as drive V
Server B as Drive W.
would there be any problem with this setting?
FYI, I'm using HP StorageWorks EVA4400 2C2D

Re: Using the same LUN to a different server
I just wanted to know if a Logical drive in SAN can be presented on a different server.
E.g
Server A as drive V
Server B as Drive W.
would there be any problem with this setting?

Re: Using the same LUN to a different server
But you need to have a cluster aware filesystem on the LUN, otherwise you can easily corrupt your data!
Hope this helps!

Torsten.

Re: Using the same LUN to a different server
However you *must* be running some form of clustering software on your two servers.
If you don't and Server B tries to mount the Drive when it's already mounted on Server A, you *will* corrupt the file system.

Rob

Re: Using the same LUN to a different server
You could present the lun to server 1, create a share on that server, map the share to a drive letter on the second server.
You can not otherwise do this unless you have a clustered file system of some sorts... Polyserve, Veritas, etc.
Even with a Windows Cluster, you can not access the same disk from multiple servers at the same time.
How are you looking to utilize the LUN?
