Hi All,
I have a problem creating a cluster that has just got me stumped.
I've created two other clusters at two other sites with exact same hardware and configuration. All worked fine at those location.
For this third location, the cluster build is not going so well.
I have 2 x Dell server for a 2 node cluster, and a Dell SAN. There are iSCSI HBAs and switches for iSCSI and a flat network for the LAN and Management on another switch. The heartbeat is connected via a directly connected cable.
The nodes are running 2012 R2 Core, with latest patches (April 2015).
Firewall is disabled by Group Policy, both on servers and Domain Controller.
The Domain Controller at this site is on the local LAN.
On each future cluster node, the LAN cards can ping the Domain Controller by name and address (using -S to verify the source address). On the DC it can also ping each LAN interface, again both by name and IP. Heartbeat NICs can similarly ping each other.
Using a Management Server on a remote subnet (Domain Account, local admin of all concerned servers, except the DC, and having read/write on the target OU), the Cluster Validation Wizard fails, on one node only.
I'm getting an error message on "System Configuration\Validate Active Directory Configuration" of:
Connectivity to a writable domain controller from node DEN1NTHV02.mycorp.net could not be determined because of this error: Could not get domain controller name from machine DEN1NTHV02.
Node(s) DEN1NTHV01.mycorp.net can reach a writable domain controller.
Node(s) DEN1NTHV02.mycorp.net cannot reach a writable domain controller. Please check connectivity of these nodes to the domain controllers.
The computer accounts are in the same OU, and both are enabled and have no (seeming) other problems.
So, (1) does anyone have any idea, or (2) where can I find the verbose output text of the failed test?
