MSA 1500 disks not available for Windows Cluster

Sure I am missing something simple here.

Already have the MSA1500 setup with SSP for my 2 Enterprise servers for boot volumes and dedicated data arrays. Now looking to leverage cluster server with the remaining data space. Have both servers connected with Fibre, setup the disk volume as basic, formated to NTFS. Have SSP only to the first server in the cluster. Successfully create the cluster, but when I go to add the physical disk, it is not listed in the drop down box.

Am I missing something?

Re: MSA 1500 disks not available for Windows Cluster

Both HBA WWNs from ALL Cluster nodes need to be assigned (ownership) to all disk/LUNs the cluster needs to see.
If you clustered the 1st node already, doesn't that mean it recognized your external Quorum drive?

If you setup your data disks for the cluster after clustering, and have NTFS'd them and assigned a DrvLtrs, you should be able to add the disk resources any cluster group.

The GUI to do this is funny because at the point you expect to see the disks to add, you have to go to the next screen to get the drop down list of available disks. Select them one at a time and from the group window bring them online.

When adding the 2nd node (that also has SSP permissions to the cluster disks) you can bypasss part of the setup by opening Advanced and checking the "...dont look for all the disks" option. This just speeds up the 2nd nodes joining the cluster.

I am interested in your boot from SAN stuff. Do you use HP docs to set this up?

Re: MSA 1500 disks not available for Windows Cluster

And that is part of the problem. I am not sure how on the MSA to assign a LUN for clustering.

I have done the SSP and set it to use just the 1 node. Does enabling the disk for multiple nodes make it automatically a clusterable disk? Or is there something within the fibre channel itself it needs to setup.

On the clustering setup side, all I have done is run the initial configuration wizard, and have the cluster responding by names and pings. I can't actually select any of my mounted luns when I get to the screen.

Re: MSA 1500 disks not available for Windows Cluster


I am assuming you have redundant HBAs in both nodes. ALL CL Node HBAs listed in SSP need to be assigned to the LUNs that you want in the cluster.
U SAID ""Does enabling the disk for multiple nodes make it automatically a clusterable disk? ""
MY ANS : YES
With dual HBAs you would have to be running Multipathing software, and Node1_HBA1 going to sw1: and Node1_HBA2 going to sw2; and same for Node2.

As for not seeing the other disks you want to use for the cluster...Either
You can see them in Disk Management? For the cluster to see them they have discovered by the host. If so then they should be available to the 1st cl node.
Or
There is a switched fabric issue and how your FC cables are layed out. Shud B as mentioned above.

Re: MSA 1500 disks not available for Windows Cluster

Is it a requirement to have a redundant HBA, FC Switches, and MSA1000 controller in the MSA1500? Because those are not to be added to this client until next fiscal.

Re: MSA 1500 disks not available for Windows Cluster

Generally, Yes.
Your actual failover is much more limited if your not using redundant HBAs, switches, and MSA controllers, and your facing downtime for a controller failure.
A couple more questions.
Is this Windows2003?
SQL cluster?
What MSA firmware are you using?
Is your current hardware config:
1 Controller
1 switch module, or 1 HUB?
1 HBA in ea Node?
2 servers with exact same hardware, mem etc?
