3 Node Failover Cluster With iSCSI

Is there any information available on the steps to create a 3 node failover cluster with iSCSI storage? Is there a step-by-step guide? I looked around but couldn't find much. Thanks!

Hi SCPSTech,
The 3 node cluster create steps same with 2 node, you can refer the following step by step white paper create the 2 node cluster then add the another node to cluster.

Guest two node Failover Cluster with SAS HBA and Windows 2012 R1

Hi all, i have two IBM x3560 brand new servers with V3700 IBM Storage. The Servers are connected to the storage through four SAS HBA adabters (two HBA's on each server). I want to create a two node guest Fileserver Failover Cluster. I can present the
LUN's to the guest machines, but when i 'm running the cluster creation wizard it can't see any disk. I can see the disks on disk management console. Is there any way to achive this (the cluster creation) using my SAS HBA presented
disks, or i have to use iSCSI to present the disks to my cluster?
Thank you in advance, George

1) Update to R2 and use shared VHDX which is a better way to go. See:

2) If you want to stick with non-R2 (which is a BAD idea b/c tons of reasons) you can spawn an iSCSI target on top of your storage, make it clustered and make it provide LUs to your guest VMs. See:
iSCSI Target in Failover

3) Use third-party software providing clustered storage (active-active) out-of-box.
I would strongly recommend to upgrade to R2 and use shared VHDX.

2 Node Failover Cluster - ISCSI Disks as 1 volume?

Hi,
Not sure if I'm in the correct forum. If I am I apologize. I need some advice.
I have created a 2-node failover cluster with 2 HP Blades. I also currently have 2 NAS Servers (HP X1600 24tb servers running 2008 Storage server) -- The ultimate goal would be to combine all of the storage space from the NAS's into 1 volume addressable
by the failover cluster. (As well as disk space from any additional NAS's added in the future.)
Right now, I can add the ISCSI disk space from the NAS Targets as different volumes under cluster shared volumes. Because of the 16TB limit in the ISCSI target, I essentially have 2 ISCSI disks on each NAS. One for 16TB, and the other for 4TB (The
NAS Drives are configured for RAID 5 so there's a 4TB Loss.) So, I have 4 ISCSI disks in the cluster, each as their own volume.
Any thoughts on making the 4 drives addressable as one volume?
Regards,
-Eric

We're running Server 2012 Data Center on the cluster nodes.
I was thinking the same about the 3rd party software to do what I'd like it to do. The data is mostly security camera video from our security system. Since its not really critical data, i'm just looking for a way to maximize
the available hard drive space, and make it addressable as one volume or network share...
-Eric
You can build Storage Spaces (simple, not clustered as it would waste 50% of your capacity, MSFT can do mirror and parity with R2 for clustered only) from iSCSI LUs. Dog slow and unsupported but you'll have linear spanned space. See:
Rough Guide To Setting Up A Scale-Out File Server
http://www.aidanfinn.com/?p=13176
Creating Virtual SoFS with shared VHDX
http://www.aidanfinn.com/?p=15145
you don;t need SoFS (obviously) but in this article Aidan creates Storage Spaces from iSCSI LUNs.
Good luck!

2 node failover cluster power down

I have a 2node failover cluster. When I power down a node that has the SQL server instance and resources, all the resources and service failover to the other node. When I see that all the resources and service report "online" I then power
that node. I am being told that this is improper because failover may not have completed. Is that correct?
Also, in our 2 node failover cluster is there a proper sequence to restarting the powered down nodes?

Hi,
The cluster group containing SQL Server can be configured for automatic failback to the primary node when it becomes available again. By default, this is set to off.
To Configure:
Right-click the group containing SQL Server in the cluster administrator, select 'properties' then 'failback' tab.
To prevent an auto-failback, select 'Prevent Failback', to allow select 'Allow Failback' then one of the following options:
Immediately: Not recommended as it can disrupt clients
Failback between n and n1 hours: allows a controlled failback to a preferred node (if it's online) during a certain period.

Windows 2008 R2 cluster with iSCSI storage.

We have a 2 node cluster setup with iSCSI storage. Is there a way to set the storage so that it becomes active on a specific node, when that node is online? The storage is failing over properly but we have to do a manual failover to get the
server back on the "primary" node.

Actually it's a way it should work from the very beginning... Make sure you did not disable automatic fallback. See for more information:

How to make 2 Node File Cluster with SAS Disks

Hello,
I cant fine any detailed, specific information and answer on this question
I have 2 Servers, Say HP, with 4 SAS disks each, 1 for OS (2012R2Data) and 3 available.
I want to create fault tolerant SMB 3.0 share for my Hyper-v nodes, to make hyper-v FT cluster afterwards.
So, I see inr equirements that SAS disks will work, but during creating cluster, I can not manage Cluster to see disks from both servers (total 6 free units)
If it is made via ISCSi target, both servers have access to that targets and cluster sees all available through iSCSI disks, but how to mnake SAS disk available to other server?
Is it possible what I need with this configuration? is it a option to make each server iSCSI target and initiator? (but it would be way complicated and slow, I think).
so, what I have misunderstood, how to make FT file Cluster with 2 servers with SAS drives?
Any info about this SPECIFIC config would be welcomed, or any general step-by-step guides (please, do not link me guides with other config, like iscsi or with additional servers, I have seen a lot of them :()
thanks

You cannot do what you want with a Microsoft built-in tools. MSFT require you to take your SAS disks away from your servers, buy a SAS JBOD (better more then one to get advantage of a so-called "enclosure awareness" and avoid single point of failure) and
configure Clustered Storage Spaces with now *external* SAS drives. See:
How to Configure a Clustered Storage Space in Windows Server 2012
http://blogs.msdn.com/b/clustering/archive/2012/06/02/10314262.aspx
Prerequisites
A minimum of three physical drives, with at least 4 gigabytes (GB) capacity each, are required to create a storage
pool in a Failover Cluster.
The clustered storage pool MUST be comprised
of Serial Attached SCSI (SAS) connected physical disks. Layering any form of storage subsystem, whether an internal RAID card or an external RAID box, regardless of being directly connected or connected via a storage fabric, is not supported.
Windows Server 2012 R2 had flexed out some limitations so now ReFS is supported (but useless as VMs cannot be integrity checked and protected) and now you can use parirty spaces (also useless as they are DOG slow with a typical VM workload dominated by small
writes, say 4KB write initiates 256KB+ parity stripe read-modify-write update). Core requirements "SAS everywhere" is still there.
So if you don't want to mess with SAS JBODs you may give a try to a virtual SAN solutions available on the market. They can cluster a pair of hosts (even with a single port SATA drives) w/o any external hardware, only Ethernet required. There are even free
options available. See:
Free Virtual SAN
http://www.starwindsoftware.com/native-san-for-hyper-v-free-edition
Also Google (or Bing?) for DataCore and SteelEye as they have very similar native (Windows-based) offerings. + there's bunch of a VM-running storage doing more or less the same.
Hope this helped a bit :)

How to Perform Forced Manual Failover of Availability Group (SQL Server) and WSFC (Windows Server Failover Cluster) with scrpiting

I have a scenario with the three nodes with server 2012 standard, each running an instance of SQL Server 2012 enterprise, participate in a
single Windows Server Failover Cluster (WSFC) that spans two data centers.
If the nodes in the primary data center are unavailable due to data center outage. Then how I can able to access node in the WSFC (Windows Server Failover Cluster) in the secondary disaster recovery data center automatically with some script.
I want to write script that can be able to check primary data center by pinging some IP after every 5 or 10 minutes.
If that IP is unable to respond then script can be able to Perform Forced Manual Failover of Availability Group (SQL Server) and WSFC (Windows Server Failover Cluster)
Can you please guide me for script writing for automatic failover in case of primary datacenter outage?

You are trying to implement manually what should be happening automatically in the cluster. If the primary SQL Server becomes unavailable in the data center, it should fail over to the secondary SQL Server automatically. Is that not working?
You also might want to run this configuration by some SQL experts. I am not a SQL expert, but if you have both hosts in the data center in a cluster, there is no need for replication between those two nodes as they would be accessing
the database from some form of shared storage. Then it looks like you are trying to implement Always On to the DR site. I'm not sure you can mix both types of failover in a single configuration.
FYI, it would make more sense to establish a file share witness in your DR site instead of placing a third node in the data center for Node Majority quorum.

Automatic restart of services on a 1 node rac cluster with Clusterware

How do we enable a service to automaticly start-up when the db starts up?
Thanks,
Dave

srvctl enable service -d DBThanks for your reply M. Nauman. I researched that command and found we do have it enabled and that it only works if the database instance was previously taken down. Since the database does not go down on an Archiver Hung error as we are using FRA with an alt location, this never kicks in and brings up the service. What we are looking for something that will trigger off of when the archive logs error and switch from FRA(Flash Recovery Area) to our Alternate disk location. Or more presicely, when it goes back to a Valid status(on the FRA - after we've run an archive log backup to clear it).
I found out from our 2 senior dba's that our other 2 node rac environment does not suffer from this problem, only the newly created 1 node rac cluster environment. The problem is we don't know what that is(a parameter on the db or cluster or what) and how do we set it?
Anyone know?
Thanks,
Gib

2 Node Hyper-V failover cluster with sql server

I have 2 IBM Servers with Server 2012 installed and both machines have SQL server express. Is it possible to create HYPER-V Failover between the 2 servers including the SQL SERVER Instance meaning if the main node fails the second server will take over.
The second will act as virtualized failover of the main node with failover instace to act as active to active approach.
I hope can someone give me an advice with my question.

Sure you can do that. But it's a long story what's better SQL Server FCI or AlwaysOn. See:
FCI Vs. AlwaysOn
http://msdn.microsoft.com/en-us/library/ff929171.aspx
(biggest issue with AlwaysOn - it does require Enterprise license so is COSTY)
Good idea to ask here:
SQL Server High Availability and Disaster Recovery
http://social.technet.microsoft.com/Forums/sqlserver/en-us/home?forum=sqldisasterrecovery
In any case you'll need either physical or virtual shared storage. For FCI to host everything and witness disk and for AlwaysOn just for witness (AlwaysOn does replication between DAS on it's own).
Good luck :)

Error on setup failover cluster with Windows 2008 R2 enterprise and SQL Server 2008 R2 (also with SP1)

Hi!
The setup process fails with this error:
Configuration error code:
0x1C2074D8@1216@1
Configuration error description: There was an error setting private property 'VirtualServerName' to value 'CLUSTER02' for resource 'SQL Server'. Error: Value does not fall within the expected range.
I have found some hints by google, but nothing really helpfull.
Has anyone had a simular problem when installing SQL server 2008 R2?
All posts I found are about sql server 2008 (no R2!).
The cluster itself is working (storage, network, msdtc, quorum...).
Any hints?

Hi Andreas Plachy,
Please make sure that the Virtual Server Name ‘CLUSTER02’ is unique on the network. In addition, are there any resources named ‘SQL Server’ on the Windows cluster? If that is the case, you may need to rename the related resources to avoid conflicting with
SQL Server, and try again.

HyperV 2012 R2 Failover cluster, HV problem, all VMs restart

Hello, I have 2 node Failover cluster with two nodes, Hyperv 2012, multipath SAS storage MSA2000. But hardware problem with one node (node2). It shutdown unexpectly. When It hapens NODE1 restar all VMs it is normal? It was configured by cluster validation
tool. There is no witness. I don't clearly understand what happens if one node crash. KR.

As Eric has said it will start the VM's in a crash consistent state on the non crashed host.
But from your example I take your seeing your guests on the non crashed host restart. If this is the case I would say yes! I have seen this happen before. It can happen if your not using quorum because only one node has a vote. I would recommend you create
a witness, on your MSA 2000 carve out 1 GB and do a disk witness. Or if you have a server not in the VM cluster you could do a file share witness, file share is my preferred. Once you have a witness in play you will see all of your hosts having a vote. Look
in the cluster manager at the nodes section. You should see a vote column. Currently it will say 1/0, once the witness is created it will show 1/1.

CSV V/s Pass through disks with HV 2012 R2 failover cluster

Hi
We are using HV 2012 R2 failover cluster with CSV. We found some articles saying pass through disks outperforms CSV. Is this correct?

"The juice isn't worth the squeeze" (c) ...
Tim is 200% correct here: any performance gains (if any...) you'll get will fade in darkness compared to management burden you'll have with pass-thru disks (issues with failover, VM migration and no
real support with a major VM backup vendors). Making long story short: don't do it.
StarWind Virtual SAN clusters Hyper-V without SAS, Fibre Channel, SMB 3.0 or iSCSI, uses Ethernet to mirror internally mounted SATA disks between hosts.

Network Name Resource Availability - failover cluster error 1196 on Hyper-V 2012 R2 nodes

Hello,
We're getting this error in our even logs of our four node failover cluster, we tried deleting Host A record in DNS management, that did nothing.
Failover cluster event: 1196
"Cluster network name resource 'CAUCrgt8' failed registration of one or more associated DNS name(s) for the following reason: This operation returned because the timeout period expired.
Ensure that the network adapters associated with dependent IP address resources are configured with at least one accessible DNS server."
And this resource http://technet.microsoft.com/en-us/library/cc773529%28v=WS.10%29.aspx did not help in solving this.
Do you guys have any other suggestions we could try to resolve this error?

Hi Jonas,
Please offer us which platform server you are using, such as if you are using server 2012 please refer the following update first.
Recommended hotfixes and updates for Windows Server 2012-based Failover Clusters - http://support.microsoft.com/kb/2784261
If the update not work please ppply Full Control permissions for the Cluster Name Resources in the DNS console.

Failover Cluster 2008 R2 - VM lose connectivity after live migration

Hello,
I have a Failover Cluster with 3 server nodes running. I have 2 VMs running in one the the host without problems, but when I do a live migration of the VM to another host the VM lose network connectivity, for example if I leave a ping running, the ping command
has 2 response, and 3 packets lost, then 1 response again, then 4 packets lost again, and so on... If I live migrate the VM to the original host, everything goes OK again.
The same bihavior is for the 2 VMs, but I do a test with a new VM and with that new VM everything Works fine, I can live migrate it to every host.
Any advice?

Hi Cristian Ruiz,
What your current host nic settings now, from you description it seems you are using the incorrect network nic design. If you are using iSCSI storage it need use the dedicate
network in cluster.
If your NIC teaming is iconfigured in switch independent + dynamic, please try to disable VMQ on VM Setting for narrow down the issue area.

Hi!
thank you for your reply!
Yes, We are using iSCSI storage, but it has its own NICs for that (2 independant NIcs just to connect the server with the storage) and they are configured to not use those NICs to cluster communication. The team configuration is just for the LAN connectivity.
The NIC teaming is configured using BACS4 software from a DELL server and in Smart Load Balancing and Failover (as you can see here
http://www.micronova.com.ar/cap01.jpg). The link you passed is for Windows Server 2012 and we are running Windows Server 2008 R2, BUT as you can see in the following capture the NICs has that feature disabled
( http://www.micronova.com.ar/cap02.jpg ).
One test that I'm thinking to do is to remove teaming configuration and test just with one independant NIC for LAN connection. But, I do not know if you think another choice.
Thanks in advance.
Cristian L Ruiz
Sorry, another choice I'm thinking too is to update the driver versión. But the server is in production and I need to take a downtime window for test that.

How to install a database on a MS Windows 2008 R2 failover cluster?

Hello,
I have to install a Oracle 11g R2 database onto a MS cluster (Windows Server 2008 R2 Failover Cluster with 2 nodes and shared storage). I installed the DBMS on both nodes. On the first node, I created a tablespace, the files are on the shared storage. I can connect to that database, up to here everything is fine.
But the problem is: How do I have to configure the DBMS on the second node to use the existing database files in the case when the second node gets the Cluster IP and the shared storage? The switchover is done, all database files (in the filesystem) can be seen on the second node.
The goal is to connect to the database from an external application, regardless which node is active.
I know the "Oracle Fail Safe Manager", it is already installed on both nodes.
A link to the related documentation would be helpful, I can't find anything.
Best regards,
C. Jost

Hello,
But the problem is: How do I have to configure the DBMS on the second node to use the existing database files in the case when the second node gets the >Cluster IP and the shared storage? The switchover is done, all database files (in the filesystem) can be seen on the second node.When you switch the database from one node to another one do you have any error ?
Can you connect to the database and check for the Tablespaces ?
Normally, with OFS you define Groups. In one Group you'll have the Database, the Disk, the IP address and the Listener. So when you move the Group from one node to another one, the disk will be recognized on the second node then, the database, listener, ... will start and, there's no reason to loose a datafile.
Please, find enclosed, an introduction to Oracle Fail Safe concept:

Hope this help.
