Hi!
Is it possible to have ISCSi Target and Hyper-V Role on the same server and assign ISCSi drives to VMs on the same server? We need to create two node virtual storage cluster on two VMs. Can I work if everything is on the same server?
Thanks.

Windows Failover cluster across datacenter. Node showing down with network unavailable
hi Team,
We have 3 node windows cluster running SQL FCI. 2 node are at primary DC and 1 node is at DR . I am observing that node 3 is started showing as down in cluster manager and its networks as 'unavailable'. 2 nodes in primary are up and running with SQL FCI.
while running Cluster validation on node 3, i am observing that even IP configuration validation , detecting update level fails though node1 and node 2 are listed. Pls. find error below. not able to figure out what is going on with the cluster and showing node 3 down. Any pointers will be appreciated. Thanks

In-place upgrade/migration of a 2-node cluster
Hello,
we have 2 servers running Windows Server 2008 R2 x64 SP1. Those are physical servers running high-availability cluster, so they have Hyper-V installed, and have a storage array.
I have instructions on how to upgrade from 2008 R2 to 2012 R2, and I understand the instructions. But I can't find any info on is it possible to move directly to 2016? I know I could gor from 2008 R2 to 2012 R2, then from 2012 R2 to 2016, but that's double work. And everywhere I looked I couldn't find info on is it possible to go directly from 2008 R2 to 2016.
I know I will have to do the clean install (i.e. no "upgrade" is possible), but I'm wondering if the wizards for migration of HA cluster will work, as in documents that describe upgrade from 2008 R2 to 2012 R2.
Document's I'm using:
https://blogs.msdn.microsoft.com/clustering/2012/06/25/how-to-move-highly-available-clustered-vms-to-windows-server-2012-with-the-cluster-migration-wizard/

Thank You!!

One Node in DR shown as Down status and network unavailable
Hi Team,
I have Windows Cluster with 3 nodes . Plan is to configure AG between Primary and DR datacenter. Node from DR site is showing as down status in cluster manager with all its network interfaces status as 'unavailable'. Our network team has recently configured firewalls between primary and DR sites, just wondering if this could be due to some port on firewall between site subnets?
Any pointers will be appreciated.

Possible problems with Destroying a File Server cluster?
I have a 2008R2 file server cluster that is extremely critical. It is actually running 2008R2 Storage server with SIS and Microsoft recommends re-inflating the volumes before moving to a new cluster. The current cluster has one node that is so corrupted that we have disabled the cluster service on it, and the shared storage also has enough latency that it causes the other node to occasionally have problems when we try the sisadmin commands or sometimes just fails a datastore as offline. We are thinking that because of these cluster issues with one bad node+bad performing storage that we are probably better to simplify everything and destroy the cluster and go back down to a single node and hopefully it will handle the storage concerns better. Then we can focus on getting the data re-inflated and migrated to a new 2012R2 cluster. That sounds a lot simpler than hoping the cluster becomes more stable when messing with cluster timeouts, etc.
I have never done this, but I am thinking that I just destroy the cluster, delete the cluster computer account, rename the current working node to the cluster name and use the cluster vip, and recreate the shares that it should work fine. Most of our ownership on the datastores are set to the default 500 account and I am thinking that data should come across with all the same ACLS, etc. Does anyone see any concerns with this plan or have any other advice?
Thanks,
Dave

OPS Microsoft Server Medium: The system detected an address conflict for IP address 10.x.x.x with the system having network hardware address 00-xx-56-xx-xx-xx. Network operations on this system may be disrupted as a result.
Hi All,
Whenever my cluster resource move from one Node to other I am getting few error/warning message. Can anyone help me to understand why?
Cluster 2012R2
Witness File Share
Application Cluster: SQL Always On
Cluster resource 'ALXXXX_172.xx.xx.xx' of type 'IP Address' in clustered role 'ALxxxx' failed.
Based on the failure policies for the resource and role, the cluster service may try to bring the resource online on this node or move the group to another node of the cluster and then restart it. Check the resource and group state using Failover Cluster
Manager or the Get-ClusterResource Windows PowerShell cmdlet.
Cluster IP address resource 'ALxxxx_172.xx.xxx.xx' cannot be brought online because a duplicate IP address '172.xx.xx.xx' was detected on the network. Please ensure all IP addresses are unique.
Cluster node 'Node04' was removed from the active failover cluster membership. The Cluster service on this node may have stopped. This could also be due to the node having lost communication with other active nodes in the failover cluster. Run the Validate
a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapters on this node. Also check for failures in any other network components to which the node is connected
such as hubs, switches, or bridges.
The Cluster service is shutting down because quorum was lost. This could be due to the loss of network connectivity between some or all nodes in the cluster, or a failover of the witness disk.
Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapter. Also check for failures in any other network components to which the node is connected
such as hubs, switches, or bridges.
File share witness resource 'File Share Witness' failed to arbitrate for the file share '\\Filer006\QA_xxx_xxx'. Please ensure that file share '\\Filer006\QA_xxx_xxx' exists and is accessible by the cluster.
The cluster Resource Hosting Subsystem (RHS) process was terminated and will be restarted. This is typically associated with cluster health detection and recovery of a resource. Refer to the System event log to determine which resource and resource DLL is causing
the issue.
I checked cluster logs also but not able to find anything here, My cluster is working fine even after getting this error/warning.

Cluster Validation - iSCSI port unreachable to UDP 3433
Currently I just upgrade my 4 production servers from Server 2012 to Server 2012 R2 and rebuild my Cluster with the same IP. But I encounter an issue that my cluster validation is failed because of 2 server's iscsi port is unreachable to other node. Below
are the screenshot of the error. I have went through some articles and tried to solve it but still failed. Besides, I also turn of the windows firewall for 4 nodes for temporary testing.

Quorum Disk on Passive Node.
Hi,
Since I am new to Windows cluster setup I have below doubts.Can someone, please provide information on below?
>>I have seen that the quorum disk is at passive and the remaining shared disks are at active node.In another server setup,we have shared disk and quorum disk on the active node.
Is that fine?
>>When we do failover I am sure that all shared disks move to the active node.I think quorum disk also moves to the active node.
Is that correct or it stays only on one node.
Thanks,

Cluster Network name resource could not be updated in domain
Hi,
I have the following error and need clarification on the below solution in bold:
Event Id 1206 -
The computer object associated with the cluster network name resource 'Cluster Name' could not be updated in domain 'xxxxx.xxxx'. The error code was 'Password change'. The cluster identity 'ClusterGroup1$' may lack permissions required to update the object.
1 - Move CNO back to the Computers Container
2- Give the Cluster Node Computer Accounts Change Password permission on the CNO
3 - Take the Cluster Name Resource offline
4 - Repair Cluster Name Resource
5 - Bring Cluster Name Resource back online
Firstly, is there any implication?
Secondly if ClusterGroup1$ is my CNO (Cluster Name Object) then is my cluster node computer account the server nodes in the cluster? E.g. ClusterGroup1$ is the cluster, the nodes are hyperv01 and hyperv02, do I add hyperv01 and hyperv02 to clustergroup1 -- properties -- security?
Thank you.

File share witness folder
Hi,we have created the cluster with file share witness. Where can I find a file Witness.log which contains the membership information for the Cluster?I tried to check at C:\cluster storage. But this folder is empty.How to open a file share witness path? It is like \\abcdef\fswpath.How will we come to know that the SQL server account has access to it?
Kindly request your help to get these details.

nic teaming live migration config
I have a new 2-node hyper-v cluster with the following config:
2x 10gb nic for VM/LM; dynamic LACP team; VM vlans 101-151; LM vlan 96
4x 1gb nic for VM/LM; switch independent team
1x 1gb nic for management
Connected by a 3-switch stack of Cisco Catalyst 3750-X
I am able to run VM's on the 10gb nic just fine, but I can't do live migrations over it. I have tried setting a static ip for the team and made sure they were all on vlan96. The hosts can ping the switch, but can't ping each other even though the firewall is off. I also tried forcing live migrations to happen over the 10gb nic in the failover cluster manager mmc.
My two port-channel setups are pretty basic (port-channel 1 & port-channel 2):
switchport trunk encapsulation dot1q switchport trunk native vlan 96 switchport mode trunk ip dhcp snooping trust
and then add the appropriate tengig interfaces to those groups.
I've checked the NIC Teaming console for both servers, and the team shows an OK status for the teams.
What am I missing to get this configuration working?

Hyper-V host reboots during live migration
Hi, I have a two node failover cluster (DELL R815), they have direct attached storage and they are connected to a 10Gb fiber switch (domain network), then a cable connects the two nodes directly through integrated 1Gb ports (live migration network) . When I migrate VMs, the destination host reboots at a certain point, no matter if I move VMs manually or if I do pause --> drain roles. The dump shows an error on evbda.sys that seems related to Broadcom drivers, but I tried to perform live migration on both networks and it always fails. I have around 25 VMs, it crashes at about 18-20 VMs, I thought it could be some defective ram modules, but I ran several memory tests and stress tests without results. I also tried to update network drivers to the latest release (now called QLogic) with no luck. I read somewhere to disable VMq, I tried it on 1Gb network with no luck.
I really don't know how to proceed in diagnostic. Hosts are patched (one is really full patched, the other is a few months back because I can't migrate VMs to patch it!)
Thank you

How can I manage a Windows Server 2012 Failover Cluster from Windows Server 2008 R2 or vice versa?
Good day,
I have a setup whereby I access one of the clients I provide support to using a jump server. The jump server is running SRV2008R2 and I can manage the clusters setup with same OS version, obviously, but I am not able to manage the SRV2012 clusters from the jump server. Every time I work on the clusters, I have to connect via the jump server and manage the 2008 clusters from there, but then I also have to mstsc to one of the 2012 servers to manage those cluster there.
If I cannot manage 2012 clusters from 2008, I thought perhaps I can then manage all clusters (2008 & 2012) from the 2012 box, but it delivers the same message there when trying to manage a 2008 cluster from 2012.
The message is:
The cluster to which you are attempting to connect is not a version of the
cluster supported by this version of Failover Cluster ManagerThank you in advance for any and all feedback.

Replication of VMs with shared VHDX is not supported
A typical Microsoft half baked solution (shared vhdx) - can use them, but nothing else, no backup, no replication.
Obviously for DR purposes that is unacceptable!
How can I DR my environment offsite when it is not possible? All my services (File/print/sql/mis) run on 2012 R2 clusters spread across different hosts
Any ideas?

no access to csv - clusterstorage.000 - w2k12r2
I created a 3 node cluster with different san based cluster shared volumes. These were used as csv volumes. I have 8 volumes in total. Now on
two of the nodes there is a problem accessing vms located on csvvolume 7 and 6. I noticed that there is a volume named clusterstorage.000 and that the link volume 7 (6) in clusterstorage it's not working so a live migration to the nodes always fails. To solve the issue I removed the note DRM the cluster and readded it. No change ...
