New server, connecting with MSA1000 with excisting HBA

[pmjteheux]

Hi,

Our old clusterservers (DL380 G2) will be replaced by G5's. 1 server is not functioning anymore, so we are using it's HBA's to make the connection to the switch of the MSA1000. We can see the drives on the MSA using ACU, but not in the OS (W2k3). The old server is running W2K, so clustering between the old and new server is not an option. What do we have to do to get the drives available in the W2K3 os of the new server and start building our new cluster there? The reason that we keep using the HBA is to keep the same configuration of the MSA.

You can see the MSA, the disks and the logical units on it in ACU, from the new server? Then there's physical connection.
Check in Windows device manager and click "scan for hardware changes".
Also, this server has only one HBA or 2? Have you installed MPIO multipathing software?

We have indeed 2 HBA's. The first time we saw all the drives double, but we installed the tool, so we see all the drives just once.
We also saw the drives appaer in W2K3 for once or twice, but we couldn't see any data in de drive management, it said there was only unallocated space.

Ah, that's another matter. The server sees the disks, the problem is that Windows does not see the data on the disks.
This can happen when moving a disk from a server to another, and it's a software problem, not hardware.

So what do we have to do to get the data accessible? We couldn't make a cluster.... clustering w2k3

if the windows disk management is seeing only unallocated space try import foreign disks.

Right click drive and select "import foreign disks" if you have a raid solution you will see mulitple disk groups. Import disks and you should see the data.

Before you do the above it is wise to export the shares registry from the following location

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\Shares

Hope this helps
