Problem with SnapDrive 6 and Windows 2008 Cluster (3 Nodes)

Hi all

I have a strange problem , we have a 2 Node Windows 2008 Cluster with SnapDrive 6 working ok

after adding another node (Windows 2008 with SnapDrive) to cluster when i try to "Connect to Disk" or "Create Disk" i got error message "RPC is unavailable"

if i remove one of the Nodes SnapDrive continue to work ok

i opened case on the issue , wanted to hear other users opinion

We are having the same issue. We cant even get the cluster validation to see the disk. Could you let us know what happens with your case.

Thanks

We solved it

did 2 things :

1.disabled Windows 2008 Firewall

2.removed iSCSI from all hosts (using FC) only

we did both of the things , maybe one of them will also work

i am not sure

good help . email me if you need help

Good to hear that you solved the issue Eli. The Windows Firewall was more than likely the issue you were seeing. Page 55 of the SnapDrive Installation and Administrator guide shows you the ports that need to be opened for normal SnapDrive operations (in case you can't totally disable the Windows Firewall)

one problem with disabling the Windows 2008 Firewall (at least with disabling the service) is that it also doesn't allow Remote Desktop to be enabled I believe.

Haven't tried disabling it AFTEr enabling remote desktop...

Hi Mark...

I have the firewall turned off (didn't disable the service though) on all of my Windows 2008 server and I can see use RDP. I forget the order in which I did everything though...but I'm pretty sure I enabled RDP then turned off the firewall...and everything is working nicely.

Just thought I'd share my observations...

Thanks...

turning off the firewall for all the machines in the cluster was a quick fix for us too. Ultimately I will configure it according to Snapdrive manual. Thank you for your help
