How to obtain target WWN for a LUN On Windows 2012 R2 Hyper-V with Fibre Channel SAN
I have a large collection of Hyper-V hosts for which I would like to retrieve the target WNN and LUN ID for the LUNs visible on each host. By target WWN I mean the storage array's WWN.
I have tried using the root\wmi namespace to retrieve MS_SMHBA_PORT_LUN instances, but I get 0 instances back.
I get instances of MSFC_FibrePortHBAAttributes back, but those only tell me the local host's HBA WWN, not the target information.
This information must be stored somewhere, because you can't access the LUN without it, I hope there is a way to retrieve it. Is there? Or is it write only during LUN setup?

Not enough memory error in Hyper-V
I have got and error tring to run Hyper-V in Windows Server 2012 r2. I have 2 gb of RAM and it says it is not enough memory. I used this official advice for Windows 8.1, http://support.microsoft.com/kb/2911380
, refused. In the it says, actualy, about DWORD that is 32 bit. I looked again in Regedit, the MemoryReserve value was gone. So I took my chances and create a QWORD (64 bit) value with the same name, and it worked. Unfortunaly, I had to reinstall the OS and
it does work. Tried thoose things several times, deleted and re-added all thoose values. Now I am confused, I wonder if there is any way to make Hyper-V to work?

Hyper-v Cluster and new AD organisation.
Hello everyone.
We have a very very bad situation.
In one of our new customers we get the following configuraion.
Organisations AD was corrupted and lost
there are Hyper-v nodes WinSrv2012 in failover cluster hosted on 8x HP c7000 blade system
there is HP P2000 datastore 49.5 Tb full size.
there isn't VMM (please don't ask me "Why"
2 CSV volumes pesented to cluster (i suppose via Failover cluster services)
And the worst thing we actually don't have any backups. I suppose previous local administrators were irresponsible.
So we have the following behavior of system
We don't able to move Virtual machines between nodes even manually.
DAtastore is full. We cannot create new LUN because All disks are used.
There are too many critical VM's which couldn't be stopped for a long time.
I have new AD but i can not rejoin nodes to the new domain because almost all node contain critical machines and as i told i can not move ones to another node as well. Also i cannot do it because in this case moved node will deleted from Failover cluster so in this case i can damage csv volumes.
Actually i can turn off each VM for a little time.
So i have a question. What is the best solution in this situation. can i use for migrate all hyper-v infrastructure to new AD but keep all most part VHD's in place.
Sorry for my EN. And Thank you in advance.

iscsi ok but disk missing for initiator
Hi,
So i set up a storage server. Created a disk pool, a VD and an iSCSI VD. Created a target and chose initiator IPs of my test host. Disk shows as ok, everything is fine.
I go to my Hyper-V host and run commands as shown below. As you can see it gets connected just fine and storage server says initiator is connected ok, but i can se no disks... Why?

Sharing VLANs with VMWare
We have an existing VMware 3.5 environment where the vlans are all set up for Management, VMotion etc.
my client is moving away from VMware and switching to Hyper v long term.
There is an immediate requirement to deploy 2012 servers. ESX 3.5 environment does not support.
Two DL385 G6 servers that are certified for 2012 have been found and I was wondering if there would be any problem in using the existing VLANs for the similar services Management, Live migration etc for the creation of a temporary Hyper V failover cluster until we have designed the new Hyper V clusters to replace ESX 3.5.

Merge Questions
I have a 500GB R1
Someone took a snapshot and deleted it a long time ago - I think back in January.
There are two VMs on the Win Hyperv 2008R2 server
1 with the snapshot has a 40GB C: and a 200GB D:
The other was a 40GB C:
I shut down the one with the snapshoot and expected the merge to just work.... however, the second server paused due to disk space issues. I am monitoring the merge process using powershell get-wmiobject (widely documented online).
What has me puzzled is the server has basically run out of drive space. When I run the get-wmi I see the precentage complete rising and the Instance IDs changing. It has been running since Friday evening.
What do the InstanceIDs mean (they dont match the UID of any of the avhds)?
As things are progressing through to different instanceids - how come the .avhs aren't shrinking or being deleted?
Will this thing ever finish? I can't start the other VM because there is no drive space available.
I ordered 2 more drives to plug into my server that has 2 slots available. My plan is to put the new drives in and move the 2 server VM to it and start it up.

Restoring physical server to Hyper V drives issue
Hello,
I scheduled the backup of all my physical and virtual servers in a networkshare.
Now I'm doing some disaster recovery test restoring a physical server in a Hyper V virtual machine but after restore prosess the system doesn't boot. I saw that there are some unusually situations: The partition drive letters are messed up. The "System reserved" patition has C: drive letter and Windows partition has D: drive letter.
So I tried to fix like before using DISKPART but it seems that the changes are not saved, when I reboot the system doesn't work and giving list vol the letter assignment doesn't change.
How can I fix it?
Thank you

No network boot-- lot of problem even with generation 2
Hi All,
I have hyperv 2012 hypervisor and i have created some vms on it. I need one of my win7 vm to boot over network. It is created with generation 1. As generation 1 has some problem to boot vms over network, i thought of creating a generation 2 vm. I have downloaded valid win8 evaluation edition iso from microsoft site. That iso is working fine for me, but when I use the same iso for my vm, it stucks at 22%. i tried almost 40-50 times. Everytime it stucks at 22% only. I am also sure that I have put it in generation 2. I also thought to create a vm with generation 1 and convert it to generation 2 (OS is win 8). But unfortunately, when i use generation 1, vm stops at 10%. getting files ready for installation (10%). In none of the generations, with none of my ISO files, it crossed 23%. Am I missing something? Please guide.
Chaitanya.

Cannot start virtual machine
Hi,
I was recently restarting a virtual machine due to applying updates and the virtual machine froze. This vm is located on one of our clusters which are running the Hyper-V role. The vm worked just fine until the restart. I was unable to stop the vm at first so I ended the process via Task Manager. Now I am unable to start the virtual machine.
The following error comes up when I try to start it:
The operation has failed. Failed to start virtual machine 'vmname'.
The details for this error are as follows:
Failed to bring the resource 'vmname" online. Error Code: 0x8007139f. The group or resource is not in the correct state to perform the requested operation.
Can you please tell me what I should do. I am thinking of deleting the virtual machine and re-creating it but would that erase the data from the virtual drive as well? Also, if this is a good idea, how would I go about giving the vm the smae IP address? Our environment only uses DHCP and does not allow static IP assignments.
Is there a way to go about this without having to delete the virtual machine? And without having to restart the entire Hyper-V node on which the vm is located on?
Thanks in advance,

Weird Hyper-V Network Issue
Hi,
We're having a very odd and elusive networking problem with a Hyper-V 2012 R2 server.
Shortly are upgrading all our servers to Server 2012 R2 and migrating to Hyper-V 2012 R2 users started to notice that Outlook would disconnect and redirected documents would become inaccessible randomly at varying times throughout the day.
After some troubleshooting we managed to isolate the following behaviour.
Pings to the VM's drop off first followed shortly by pings to the Hyper-V host.
The packets are dropped for a period of around 2 minutes intermittently around 1-2 times per day.
The timing seems completely random.
Neither the VM's nor Hyper-V host register any loss of network connection.
VM's can not talk to each other over the vSwitch whilst the problem is occurring.
Normal service resumes after usually around 2 minutes or so.
Nothing seems to be logged in the event log on any of the machines to do with network issues. The only trace we can find is EventID 2070 been logged on the exchange servers application log to say that the DC is unavailable. And on the domain controller/file server we can see LDAP session time outs and SMB handles been scavenged.
The server is running on a ML350P Gen8 (Broadcom NIC) - All firmware and drivers have been updated.
All servers are up to date with all the latest updates.
We have also tried a second Intel based NIC but this has made no difference as did swapping all network cables and the switch.
There are currently 4 VM's connected to a single vSwitch which is linked to a dedicated port on the Intel NIC - management is not allowed through this interface but is done through the second interface on the Intel NIC.
Has anyone come across this before? It is causing a lot of problems with the client and we are very close to rebuilding the Hyper-V host with an earlier version of Windows server.
Thanks,
Richard.
