HP San Array 1000

Does anyone have any advice with the following issue:

I have a set of blades (4), Windows 2000 and 2003 connected via fibre to a HP SAN Array 1000, and I have created various mirror and RADI 5 groups on the full set of 14 disks.
However when I copy or write to a file on one blade the other blade cannot see the same file on the same drive.

I am using Securepatch which is workinf fine, anyone have any ideas what the issue could be?

You would need additional software to provide you with a shared file system - neither Windows 2000 nor 2003 has that in the base operating system - not even in their clustering software which works on a 'shared nothing' base.

I was understanding that securepath was the software the allows the file systems to be shared and also resilient? If not what software can you use?

Secure Path is a multipath filter driver to work around the fact that Windows does not have any code to handle redundant paths to a LUN.

Apologies I also meant to say that provided was Veritas Foundation Suite to handle the file sharing and resilience also. When I receive the licence for this I will test.
Just thhought you may know of a good software product for this.

Hi Antonio,

Veritas Storage Foundation for Windows allows you to move disks between different servers, but I don't think you can have the same disk online to 2 servers simultaneously for sharing the file-system.
In VSFW, if a dynamic disk group is imported on server 1, it cannot be accessed by server 2 until you deport it on server 1 and then import it on server 2.
Other forum users have mentioned a product called Polyserve, which is supposed to allow simultaneous disk access for multiple servers under Windows. I have no experience with this, though.

Thanks for the reply, I also have the Veritas Cluster software, now call SANPoint Foundation suite, along with Storage foundation which should allow me to cluster and file share between the four servers(2 x Two server clusters.

Polyserve offers a clustering product that allows for the sharing of one disk amongst multiple servers.


I would not call it the BEST available software, just one that I have seen before that looks to work.

I have used Veritas Cluster software before, they now have a suite call VERITAS SANPoint Foundation Suite, which includes Clustering and file system sharing.
