DFS Storage migration options

Hi all,
I am working with a customer who currently has an active/passive DFS physical cluster running on Windows 2008 R2. They do not use DFSR at this point as they are using their SAN to do block replication at the back end.
I have been asked to assist them in providing options to change their back end storage vendor with the least downtime possible.
The following are my thoughts and I appreciate any comments or better suggestions!
Option 1
If I disable the passive nodes and enable DFSR on the cluster (then the data being replicated to the passive side is only known of by the SAN and not the cluster itself) I can then add a new node and attach the new storage to this node. Once replicated i
can then recreate the cluster pointing to just this node.
Option 2
This option is to simply attach the new storage to the current cluster and use something like Quest Secure Copy to copy the data, structure, permissions and shares to the new drive. I can then reconfigure the shares to be active on the new drive. This could
have some downtime while shares are being reconfigured, and there is a high likelihood that there is more than 50TB of data to be moved here.
Option 3
This option is very simply to do a full backup, take the current SAN storage offline then restore the backup to the newly attached storage drive. The downtime here is likely to be higher for this option.
So what is the best plan here, I'm thinking that the DFS method would be but is it as simple as enabling DFSR on a current cluster?
Many thanks for any opinions in advance!
Martin

Hi Martin,
Actually in using DFSR it will still take a long time for replicating 50TB data. Also you need to add/remove nodes from/to the cluster.
I think option 2 should be easier. Share permissions are actually stored in registry key so after copying all files from old LUN to new one, assign the old drive letter to the new LUN and shares still still working since nodes are still the same.

Hyper V Cluster Migration - Options

Hello,
I have a Server 2012 4 node cluster that i need to migrate to new hardware along with all the VMs. The new hardware will be a 2 node Server 2012 R2 cluster. Can i please have some advice on my migration options? I am using iSCSi SAN storage but have limited
available to make available to the new cluster as it is all being used by the current one.
I was hoping I could add the host to the existing cluster but that does not appear to be the case. So i think my only options now would be to either use copy cluster roles wizard or import/export process, found here: http://technet.microsoft.com/en-us/library/dn486792.aspx
If I use the copy cluster roles wizard should i setup the storage on the new hosts, as in make it available via iscsi initiator, before i create the cluster? I just have concerns about giving access to the same CSV storage that is currently live on the current
cluster. I am using SCVMM 2012 for management. Many Thanks. Carl.

Hi Alexey, thanks for your reply and sorry for my delay. I ended up setting up the new cluster, giving it some storage and live migrating the VMs - this was taking a long time so basically completed what you explained above - i used the copy cluster roles
wizard, turned off the VMs on the old cluster, bought the CSV online on the new cluster then turned the machines on. It was actually pretty much issue free which was a nice surprise. Yes there was also a chunk of downtime but luckily I managed to get approval.
Thanks, Carl.

Storage migration not possible after removing shared vhdx

I have two VM:s in VMM that I use for tests. Just completed a test of shared storage and removed the shared disks from WSFC in the cluster and then after shutting down the nodes I removed the disks from the VM:s using powershell. Now when I try to storage
migrate the VM:s (that no longer have any shared storage, HasSharedStorage = false) it says "The specified path is not a valid folder path on <host>". VMM 2012 R2 UR5. Other VM's migrate fine - just the two that had shared storage that
doesn't

That's true in general and maybe that's the problem here. It's not like there is a load of information about how to manage VMs with shared disks. For removing the shared disks I shut down the VM:s and used Hyper-V manager to remove the disks. I then refreshed
the VM: in VMM and it picked up the change without complaining.
In complete lack of procedures of how to do this, and other important stuff as how you perform configuration changes in VMM on VM:s with shared disks I think all that can be said is that there are no procedures. If you google how to reconfigure such a VM
in VMM you'll find that ONE way is to perform a change in VMM, choose the Script button and then remove all the options except the supported ones from the script and the run it in the VMM console. This is what I usually do.
Maybe if I hadn't had this problem if I used Remove-SCVirtualHardDisk instead. I'm far from sure but it's a possibility
This is just a test setup so I'm not going to spend time on researching it. However it's a good example of how immature shared VHDx is and for anyone considering it I can only recommend them to seek other options if at all possible. We have several virtual
clusters using shared VHDx and it's not pretty. It violates most of the stuff that is great with virtualization and ties the fabric to the resources. Not beeing able to storage migrate a disk is just not practically acceptable.
This is a bug of some sorts - be it functionality or lacking documentation

Cluster Live Storage Migration completes without deleting the source virtual hard disk VHDX

Testing HV setup in a cluster of two nodes with shared FC storage. Storage is CSV on both nodes. Storage migration of a VM from C:\ClusterStorage\A to C:\ClusterStorage\B completes without any problem. Upon completion, the source VHDX
are still left at C:\ClusterStorage\A. The source files can be deleted manually. All is done through VMM "Migrate Storage" option. Why the storage migration does not delete the source files upon job completion? Thanks!

I have noticed this happens when the folders are "pre-staged". If I create a folder and then storage migrate all of the files into it then it will not delete from it. If I just put the files in the root of the CSV then it seems to work. I am
looking into the permissions of the system and seeing what changes on a folder when it is created by a user and not the system. This only appears to happen when I am doing some cleanup because of duplicate machine name subfolders recently that a tech created.
If you match the permissions to a system created VM it should work though.

SAN Storage Migration with Hyper-V 2008 R2 CSV

Dears
Our customer has configured 2 node Hyper-V Cluster with CSV   connected to an Old SAN Storage The Host Operating System is Windows 2008 R2.
We are planning to migrate the data from the old storage to the new storage. ( Both Storage boxes are connected via Fiber)
With regard to the Migration can we do the below if so please provide some guidelines related to the Hyper-V queries.
(We are trying to avoid the Storage based migration)
- Connect the new storage   to the servers
- Create the LUN same as in the old storage and assign it to the servers
- Create a new CSV and point it to the new luns in the Failover Cluster Manager
- Use the export/import function to move the VM's from the new storage to the old storage
- Once all the vm's are moved create a new LUN for the quorum and re-configure the cluster to use the new quorum
Are the above steps will perform a error-free migration if so
- Can we delete the old CSV and dismount the old storage at this stage.
Also these VM's (Exchange and SQL) has seperate LUN's assigned for the Exchange and SQL data , Does these data will be exported when we use the export/import feature of the Hyper-V to migrate the virtual machine
Your Valuable response in this regard is highly appreciated.
Regards
Muralee

Dear All
Thanks for your valuable reply.
And I was able to successfully migrate the cluster and below are the steps i performed
* Initialized the SAN storage and assigned the LUN to both servers.
* Logged in to the server which is the current owner of the csv's and disks
* Initialized the disks as GPT and formatted the LUN without a drive letter.
* Added to the Hyper-V Cluster as disks
* Added to the CSV
* Exported the VM to the new disks
* Deleted the VM from Hyper-V console(Which will not delete any VM files)
* Imported the VM (chosed the default settings in the wizard)
* Added the VM as a service Failover Cluster Manager.
* After completely moving the VM's created a new LUN for the quorrum and changed the quorrum      configuration to the new disk.
* Removed the Old Storage and restarted the cluster checked for the VM's functionality everything was fine.
NOTE1 :- I faced a difficulty in multipathing software as he was using the EMC Powerpath and I had to remove it and enable Widows MPIO .
Anybody who are facing a similar scenario please send a note I would be glad to share the experience.
NOTE2 :- I tried all the SAN migration options from the storage Vendor but this method was able to do the migration in a much easier and confident manner.

Any help woulf be greatly appreciated :-)

Hi, did you manage to resolve this issue? I have a very similar issue where I have what looks like a parent checkpoint on a VM but the avhdx files have been remove or lost so I cannot remove this checkpoint. I cannot do anything with the VM whilst its there,
like migrate and backup using DPM.
Thanks.

Delete some apps, files, photos, videos, movies, etc to free up some space.
How much space is your Other using? You may be able to reduce.
How Do I Get Rid Of The “Other” Data Stored On My iPad Or iPhone?

With an iOS device, the “Other” space in iTunes is used to store things like documents, settings, caches, and a few other important items. If you sync lots of documents to apps like GoodReader, DropCopy, or anything else that reads external files, your storage use can skyrocket. With iOS 5/6, you can see exactly which applications are taking up the most space. Just head to Settings > General > Usage, and tap the button labeled Show All Apps. The storage section will show you the app and how much storage space it is taking up. Tap on the app name to get a description of the additional storage space being used by the app’s documents and data. You can remove the storage-hogging application and all of its data directly from this screen, or manually remove the data by opening the app. Some applications, especially those designed by Apple, will allow you to remove stored data by swiping from left to right on the item to reveal a Delete button.

SCVMM 2012 R2 RU3 - Live storage migration failing with error 12711 if cluster resource name is not in form of "SCVMM vmname "

At the end of live storage migration in SCVMM 2012 R2 RU3 getting error:
Error (12711)
VMM cannot complete the WMI operation on the server (hypervhost1.domain.local) because of an error: [MSCluster_Resource.Name="SCVMM test-vm"] The cluster resource could not be found.
The cluster resource could not be found (0x138F)
Recommended Action
Resolve the issue and then try the operation again.
Storage migration actually succeeds and after Repair/Ignore and Refresh, the VM shows up ok in VMM, with the VHD in new location.
If VM is offline, storage migration always succeeds. Live (non-storage) migration always succeeds.
I noticed in the error message that it searches for cluster resource name "SCVMM test-vm" and for some VMs I've got different cluster resource names.
Like for this VM cluster resource names are:
Virtual Machine test-vm
Virtual Machine Configuration test-vm
Furthermore, those resource names are showing up correctly in [VirtualManagerDB].[dbo].[tbl_WLC_VMInstance] table, columns VMResource and VMConfigResource.
Anyone knows why SCVMM keeps searching for "SCVMM test-vm" and how to fix this without recreating cluster resources?

Ok, you have the same problem and same configuration that this post:

ORA-10827: database must be opened with MIGRATE option

Hi,
We are trying to migrate an Oracle 8.1.7 database to an Oracle 9i(9.2) database. I moved all the database files to the appr folder and I created a new instance using:
oradim -new -sid PROD -intpwd Oracle -startmode a -pfile C:\oracle\OraDb\Neuropace\initPROD.ORA.
I checked the alter log file and I get the following error:
ORA-10827: database must be opened with MIGRATE option.
How should one go about migrating a database(different versions). I went ahead with the migration. I opened the database using
alter database open resetlogs migrate.
But when i log into the database, I get an internal code error.
Any pointers?.

You must not open normally your database after an upgrade, in short the method is
1) startup migrate
2) run the upgrade script (which one depends on your old database version)
For step-by-step instructions see
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96530/upgrade.htm#1009200
'alter database open resetlogs migrate' is only applicable to upgrades from version 7 to 9.2, hopefully your database is not corrupted now.

SAP Data Storage Migration from HP EVA SAN to NetApp FAS3070 FMC for M5000s

Good day all
We are needing to perform a storage migration for SAP Data that is currently on 2 HP EVA SANs. We have 2 SUN M5000s, 2 SUN E2900s and a couple of V490s, that all connect to the SAN via Cisco 9506 Directors. We have recently commissioned a NetApp Fabric Metrocluster on 2 FAS 3070s, and need to move our SAP Data from the EVAs to the new Metrocluster. Our SUN boxes are running Solaris 10. It was suggested that we use LVM to move the data, but I have no knowledge when it comes to Solaris.
I have some questions, which I hope someone can assist me in answering:
- Can we perform a live transfer of this data with low risk, using LVM? (Non-disruptive migration of 11Tb)
- Is LVM a wise choice for this task? We have Replicator X too, but have had challenges using it on another Metrocluster.
- I would like to migrate our Sandbox, as a test migration (1.5Tb), and to judge the speed of the data migration. Then move all DEV and QA boxes across, before Production data. There are multiple zones on the hardware mentioned above. Is there no simple way of cloning data from the HP to the NetApp, and then re-synching before going live on the new system?
- Would it be best to have LUNs created with the same volume on the new SAN as the HP EVA sizings, or is it equally simple to create "Best Practise" sized LUNs on the other side before copying data across? Hard to believe it would be equally simple, but we would like to size the LUNs properly.
Please assist, I can get further answers, if there are any questions in this regard.

Went into iCloud Buy More Storage Downgrade Options... got email about my phone number being changed right after???

Hi,
I've gone into the iCloud > Buy More Storage > Downgrade Options and after entering my password I received an email from Apple saying the following information for my Apple ID "id" was updated today: Phone Number(s). But I didn't change my phone number and the information currently saved for my phone number for my Apple ID is correct.
Why would I get this email? I figure it must be some kind of bug considering the information is correct and it emailed me right after I entered my password in the iCloud section. (I'm not wanting to change my password.)

The thread running through your explanation has to do with connectivity to your server. (iCloud out of the blue asking for password, unable to message your boyfriend, unable to access e-mail). You said that you boyfriend restart his device and then the two of you were able to then imessage. My best advice for you would be to go to settings to reset to reset network settings. Once this has been done you then will need to enter the name and password of your wifi. ONce this is done you then can attempt to check to see that all passwords are enter correctly.
Good luck.

How to increase storage migration job timeout in SCVMM 2012 R2

Hi,
I needed to move a VM 2+TB in size on slow storage to another volume. The VM was turned off. The VMM job failed after 9 hours and 23 seconds with following error:
Error (2924)
Unable to complete the request. Operation on the hyperv1.company.local server timed out.
Recommended Action
Try the operation again.
VHD files were copied to destination successfully, but were not removed from source and also the VM was not imported from the destination location.
So it looks like there is 9 hour default timeout for storage migration jobs in VMM.
How to increase this timeout?
Thanks,
Egils

Brian,
If you got the same timeout error sooner then my assumption that this is 9 hour file copy timeout was wrong.
In my case the files were copied successfully, the VM was was removed from Failover Cluster and Hyper-V (unregistered in source location), but was not registered in destination location, so it might be that timeout occurred during registration of the VM in
destination location.
Unfortunately the SCVMM error message does not include any details about the timeout.
Btw, there are some SCVMM timeouts that can be changed, like

Missing migration options in SQL Developer 3.1.07.42

I am using Oracle for the first time and so I downloaded Oracle Developer Days VM running in Virtual box. I need to migrate an SQL Server d/b into Oracle and so I started to use the SQL Developer application.
The VM contains the following:
Oracle Linux 5
Oracle Database 11g Release 2 Enterprise Edition
Oracle TimesTen In-Memory Database Cache
Oracle XML DB
Oracle SQL Developer
Oracle SQL Developer Data Modeler
Oracle Application Express 4.1
Oracle JDeveloper
I have downloaded and installed the SQL server java connector and I can connect to my SQL Server database, I can also create connections to the Oracle d/b.
But, I cannot find the database migration menu options when using Oracle SQL Developer 3.1.07.42, the migration menu options do no appear on the Tools menu or when right clicking a database connction.
Can anyone explain why the migration menu option is missing or how I could test the migration some other way ?
Thanks

I have discovered that the migration facility is not included with the VM.
By opening the RPM for SQL Developer and copying the migration extensions into the SQL Developer folder, the migration menu options are now available.
