Storage vMotion rename

I have a customer with large servers, that have many VMDK files and for support reasons they are created with custome filename:
<servername>-<mount point name>.vmdk
But they would like this disks to retain there name during Storage vMotion. I know there is an advanced setting on vCenter to disable renaming, but that for all Storage vMotion/migrations, What I would like is an advanced setting on the VM or even on the disk in the VMX file.

Yes know that artivcle, but that for all or none in a vCenter, what I want is a per VM setting or VMDK.
i cant restart vCenter every time I want to change that seetting.

Unstable vMotion behavior over DCI with vPC?

hi out there
I need some ideas to track a problem - we have a DC running with a wmware esxi4.1 cluster (2 x 2 sets of blade-servers - one set at each site) with a DR site which is interconnected with 4 10G fiber where we have established 2 x 2 port-channels (Cisco Nexus 5k with vPC) between - 1 vpc portchannel with 2 10g connections for iSCSI and 1 vpc portchannel also with 2 10g connections for "non-iSCSI traffic" - eg the rest - we have seperated the iscsi traffic fully from the rest of the network. We have hereby a "simple" Layer 2 DC interconnection with a latencey between the sites of ~ 1mSec - and no erros reported by any of the involved devices. The iscsi consist of two EMC VNX 5500 controlleres - one at each site with a "local" san array.
My problem is that from time to time when we issue a vMotion or clone of a vm between the sites we get either an extrem slow response (will probably end in a timeout) or the operations fails with a timeout - could be "disk clone failed. Canceling Storage vMotion. Storage vMotion clone operation failed. Cause: Connection timed out"
Any suggestions to track this? It is a bit hard to track the network connections since it is 10 gig (haven't got any sniffer equipment yet which can catch up with a 10 gig interface). Could there be some buffer allocation problems on the nexus switches (no errors logged - any suggestions on which debug level?)
best regards /ti

Hi - we have a similar setup but where we use nx5k to service the DCI and VPC as solely L2 and then run the L3 on the NX7k. You need to have all the same vlans on the vpc as far as I know. You can't fool it - but you might be able to tricks something with some q-in-q trunks between the 2 sets of nx7k's

How to supply an end point to powershell cmdlet Rename-Blob

[cross posted from http://stackoverflow.com/questions/21352295/azure-storage-cmdlet-rename-blob-wants-an-endpoint]
I'm attempting to rename a blog to all lower case:
Rename-Blob -BlobUrl "https://ttseast.blob.core.windows.net/images/Add.png" -NewName "https://ttseast.blob.core.windows.net/images/add.png"
I've verified the blog URI by plugging it into a browser - however, attempting to execute the command tosses:
Rename-Blob : Blob URI does not correspond to storage account end point. A Blob URI must contain blob storage end point.
The arguments for Rename-Blob don't reference anything 'endpoint' - I've loaded the subscription so I should be authenticated and not forced to include AccountName/Key.
How to I determine (or set) the required end point?
thx

If I'm not mistaken, I believe you're using Cerebrata Azure Management Cmdlets as Windows Azure PowerShell Cmdlets do not have a Rename-Blob Cmdlet (Cerebrata has it).
To use Rename-Blob cmdlet, please try the following:
Rename-Blob -BlobUrl "https://ttseast.blob.core.windows.net/images/Add.png" -NewName "https://ttseast.blob.core.windows.net/images/add.png" -AccountName "ttseast" -AccountKey "<your accountkey>"
Thanks to Jaydonli for the alternate approach - turns out that while I thought I was using the native MS cmlets, in fact, I was using 3rd party CLI from Redgate. As per Gaurav Mantri at http://stackoverflow.com/questions/21352295/azure-storage-cmdlet-rename-blob-wants-an-endpoint

Oracle VM Storage live Migration

Good Morning,
i am very new to Oracle VM. But i used to work a lot with other virtualization "Engines".
Now i have got set a a new OVM Cluster. with 2 OVM Server (2.2). With SAN .
So i got 2 SAN LUNS clustered over the 2 OVM Servers.
I used to have Storage live Migration (Storage Vmotion) but here i cant find anything.
In Cirtix i know there is a way (xe ). But there is no xe on OVM.
But i need to move mv VM-Guest from SAN (LUN1) to LUN2....
Is there a way to do it on OVM to (without stopping the VM Guest)?
Thanks a lot!

Yes there is (sort of, unsupported):

Migrate one HDD to different Storage

Hi Guys,
in our LAB we have two VMS with two differents HDD attached it to it,
lately we have attached extra storage and want to move one HDD to different storage
Disk 1 is 40 GB on the SSD Hard disk
Disk 2 is 1TB on Sata Hard Disk.
I want to move jus the disk 2 of 1TB to a different Data Store. and keep the Disk 1 on the SSD Data store.
i'Ve looked arround and saw there is a vMotion Data but its migrate the whole disk to one Data Store.
any suggestions how to do this ?
Thank you

You can use the Advanced Option on Storage vMotion to select just the disk you want migrate, take a look: Storage vMotion only one hard disk to another datastore in vSphere | ICT-Freak.nl

1000v and possible issue for data storage firmware upgradation

Hi all,
We have IBM N series storage controller which provide storage to esxi4.1.We have hosted out primary and secondary VSM for 1000V deployment on this ESXi4.1.
We need to upgrade the storage firmware and I like to know if their is any possible impact on my 1000V.
As this is a outage change [becuse of storage will bring dowm] i like to know why precautionary measure will be taken so that my nexus 1000v remain un affectted because of this storage controller upgradation change.
If their is any link available for refference .
Thanks in advance.

Since your storage is going down completely you will need to power off the n1k. Here are things You can do to minimize the impact of this:
1) ensure your running config matches your startup config (show run, show start)
2) ensure your system VLANS are configured correctly. Namely make the follow VLANS are system VLANS on your eths/veths that carry them: ESXi management, vCenter management, VSM management, control, packet, any storage VLAN (iSCSI or NFS)
3) make sure the VSMs have their reservations set correctly in ESX so they don't have to worry about resources during boot
Alternatively if you have a host with ESX installed on local storage you could migrate the VSMS over to that, storage vMotion the VSMS onto local storage and keep it running during the outage (though you should still verify your system VLANS)

Use OES2SP3 NSS Volume on a OES11SPx Server

Hello all
We have a couple of virtual OES2SP3 servers which we plan to replace with OES11SPx servers (on several remote sites).
Now we had the idea to mount the existing OES2SP3 NSS volume (own vmdk disk) with all the data on it to the new OES11SPx server.
With this procedure we would not need to migrate the data to the new server and would save some time.
Does anyone have experiences with such a action?
The NSS volume contains GW and a usual folder structure.
Thank you for your feedback and suggestions.
Best regards
Beat

Works fine.
The gotcha's that I'm aware of:
When you power off the OES2 VM, and "remove the disk", and then you attach it to the OES11 VM, I don't believe it MOVES the actual VMDK file or directory structure.
In other words:
OES2 VM used DATASTORE1 and the directory was like \oes2-vm\oes2-vm.vmdk
OES11 would show it like:
DATASTORE1\oes2-vm\oes2-vm.vmdk
So if/when you decomission the OES2 box, you do NOT want to do a "delete from disk" as it will whack the vmdk and directory and your OES11 box will lose the volume.
I am unsure if a storage vmotion would work (if you have the paid VMware) or if you will have to power off the VM's and manually move the datastructures around. If going from esx host to esxi host, it can be time consuming.
If all the servers are using the one esxi host, then I imagine a simple rename, etc. would suffice (ie, power off the VM's, manually browse the datastore, change the directory name, or move it into the OES11 one, etc.)
But yes, what you want to do works and I've done it many times before.
Disconnect the disk from the OES2 box, reconnect it to the OES11 box, rescan for LUNs. I don't remember if a server reboot is needed, but I always like to do that. Otherwise I think you'll have to manually run nssmu to mount the volume, etc.
Obviously if it's Groupwise you'll need to adjust any config files if you used UNC paths for stuff, along with IP addresses (ie, change the IP of the POA/MTA, rebuild the databases, etc.)

Connectivity issues for random phones in CUCM 8.6 on Vmware

I have a client that has problems with around half of there ip phones (6921 & 7945) after a situation with overheating in the serverroom.
The solutions was a 1 Publisher, 1 subscriber setup with each on a separate Vmware server.
The Publisher is connected to the Core Switch which is further connected to 4 distribution switches which again connect to 5 more distribution switches. They have around 200 ip phones connected to these switches that get assigned IP's with DHCP.
The physical disk that the Subscriber was on was destroyed the incident. The Publisher they recovered, but to do this they had to recreate the vm descriptor file and attach it to the flat-file.
So the current situation is that the system is running with only 1 Publisher and no Subscriber.
There is also a license warning in the CCM Admin section, stating a License Overage (2 nodes used, but only 1 licensed.)
The license status is not invalid though, and the license state is "Uploaded". This second node I suppose might be the Subscirber that no longer exists? The phones have more than enough licenses.
When powered up the system seems to run as it should, but only about half the phones have connectivity to and can register with CUCM.
I have tried to reboot some phones remotely by cutting the power on the switch interfaces where they are attached, but that made no difference.
The console log on the phones that are down show TFTP Timeout & File Transfer Error.
The phones that are up and running can be pinged successfully from the CUCM cli, but when pinging the others I get "Destination Host Unreachable".
The strange thing is that it seems completely random as to what phones are up or down. On all switches there are connected phones with both working and non-working connections to CUCM.
To try to pinpoint the fault I chose 2 devices on the same switch and compared the config for each interface, one that has connectivity and is registered, and one that does not have connectivity and is unreachable.
Everything seems to be identical so I can't see what causes this error on the one, but not on the other.
Also when I ping the ip phone with no connectivity to CUCM from any of the switches, the ping is successful.
Anyone know what could be the cause of this behaviour?

Hello and thank you for your time.
The phones get there IP’s from a DHCP Server (Not the built in one in CUCM, but an external server). I have tested that the DHCP process works by powering off a phone (one of the phones with connectivity issues), deleting the lease, and then powering the phone back on and seeing the device request and receive a new lease.
There is only one CCM group active and both servers are in this group with the Publisher as highest priority server. All phones are in the same Device Pool attached to this group.
There are a lot of warnings regarding dbReplication & missing node due to the subscriber being gone. Also there is an issue with NTP server (see below). I will post more on this tomorrow morning.
I have also attached the console log from one of the phones that can't register.

Differences between VMware and Oracle VM

Hi guys,
I am sure that some people have used VMware and moving to OVM or vice versa.
I am curious to get some feedback resulting from comparing both products -VMware and OVM- (pros and cons).
I am preparing some documentation so I thought of getting some feedback from experts and users.
Thanks.

The word is (from the Product Manager of Oracle VM) their engineering team is focusing on product release currently.
Avi, I am VERY happy to see you say storage management was a big item in OVM 3.0, as that is likely a good sign for other improvements (that would make the product more competitive with VMWare shops).
My quick "cons" between OVM 2.2.1 and VMware are:
OVM lacks the concept of centralized ISO image management (this could easily be resolved by implementing Server Pool level NFS mounts), in 2.2.x you need to upload (SCP or HTTP) an ISO to a OVM host, and "register" it.
OVM lacks the above mentioned SR selection when you create a VM (and related, a way to migrate VM's or images between SRs (Storage vMotion type feature).
OVM lacks snapshotting entirely. If you want a clone of a VM, you shut it down and suck up the downtime to clone the VM
OVM lacks a straight forward and flexible P2V mechanism, its a block level clone, doesnt inject drivers (SCSI, etc), doesnt give you the ability to resize drives, or any of the standard features in VMwares Converter product.
OVM lacks detailed VM image management, such as a simple method to resize (expand) an VM image. Right now we have to use dd at command line to expand a VM.img file, which is not user friendly.
OVM lacks the granular permission granting that you can do with VMware, for example, if a user account is a User, that user has rights to basically delete a VM if they wanted to. This is problematic as you may want to give a user rights to power cycle a VM, but not delete it!
OVM lacks easy network management (such as NIC teaming/bonding, vlan configuration etc), its a very command line intensive operation, again, very user unfriendly.
OVM lacks easy SAN connectivity management, same as the above, huge command line intensive operation, no tie-in to OVM manager at all.
Some of the Pros:
OVM is free to use, plus inexpensive support (primary reason we use it!)
OVM is the only VM product that Oracle will openly support its products on.
OVM is very scalable, management many guests on many servers in many server pools, single frame of management at no extra cost.
OVM is based on open source software (Xen), you can tinker in the OS, look at logs, install monitoring tools (zabbix, etc) that you could not do easily in VMware
Theres other issues we've ran across over the last year or so, but them all aside, I prefer it over VMware, but I am also a very seasoned Linux guy, I have my doubts that if you took a Windows sysadmin and asked them to setup a Oracle VM Cluster, it probably wouldn't fly.
I am not bias, I've built and managed equal sized environments in both VMware and OVM, so my above mentioned PROS and CONS are purely based on usage of the products.

Server backup Faliure Wth failing with snapshot error

Hi Team ,
One of my VM guest Machine's backup job is getting failed again and again with snapshot error .
When I checked logs I can see Event Warning " VM disks consolidation failed " where currently there is no snapshot is available on this machine.
But When I manually run the snapshot by using by using quiesce Method and then again run backup Job from Symantec , Backup runs fine 7
We are using Symantec Netbackup 7.6.1 and My VM Machine is running on ESXi01 , VM version 9 , Guest OS MS Windo 2008 R2
Any Help Would be really appreciate

Hi,
DO THIS FIRST
             a) Try to do a storage vMotion of that VM and delete the file which are left behind along with the VM folder (if any )
             b) Take a VMware snapshot and after completion , Go for DELETE ALL --> This will update the snapshot records in the VMX file and snapshot configuration file with latest number which is unique while taking the snapshot as per the process.
DO THIS AFTERWARDS
           a) STOP and set to manual service for Volume shadow copy ,VMware snapshot provider and Virtual Disk inside the Guest OS. Wait and Check for schedule backup.

VAAI Unmap delete status: unsupported NetApp FAS Array DataOntap 8.2.1

Hi All Quick run up of our environment: VMware V5.0.0 Update 3 Build 1918656 with vCenter 5.0.0 U3. NetApp FAS8020 running Data ONTAP 8.2.1 7-Mode using Thin Provisioning Flex VolumesUsing VSC 4.2.2 plugin For purposes of test this piece I created a thin provisioned 100GB LUN with a 55GB thin provisioned VM I am looking to use the unmap to reclaim space from our thin provisioned volumes on our NetApp, we are using thin provisioned VM disks however some are thick provisioned VMs as well. When I mean the volume is thin provisioned I mean when you setup a new volume on the NetApp array and tick the option to thin provision the volume as shown below: however I have run into a few problems and am struggling to understand why I am unable to reclaim space on a test thin provisioned volume I created. As a test I storage vmotioned a VM no longer needed to a test volume which utilised the space on the LUN, I then storage vmotioned it back to another volume. it removed the space on the VMware datastore side however not on the volume capacity on the storage. However having a read of VAAI in detail I am unsure why the below is showing as thin provisioning status: unknown. I can confirm the volume is thin provisioned and NOT thick provisioned. When looking at the VAAI status it shows the delete as unsupported. So I attempt to use the vmkfstools command to reclaim the space: cd/vmfs/volumes/55965500-d4fc0353-ce8c-c4346bbae697 When I tried the vmkfstools -y percentage_of_deleted_blocks_to_reclaim command it looked like it worked, tried it few different times with different %Volume status on NetApp side shows that the space hasn't been recovered and still shows at 39% used, with 61.28GB even though there are no VMs on this volume. On VMware side, it shows as space feed as expected. Does anyone know why I might be seeing this behaviour? I know on earlier versions of 5.0 there was issues and it has to be run manually however I am on a much later release of 5.0 and I thought the vmfkstool utility allowed it to be run manually? Any help would be most appreciated.
Thanks

I have found this article which relates to what I am seeing: VMware KB: Thin Provisioning Block Space Reclamation (VAAI UNMAP) does not work When I check the VMware compatibility matrix it is showing as VAAI thin provisioning space reclamation is not supported. I am using a FAS8020 array, I would have thought that this SAN considering the age would support this feature? or is it an issue elsewhere with the environment? Looking at whether I upgrade to a newer version of ONTAP or VMware ESXi it doesn't make any difference. Is the Thin Provisioning space reclamation only a feature on very high end SANs? Is there anything I can use to reclaim space? Thanks

I have run utils ntp restart on each server and still get the same error.
Any help please?

First thing is to post the status of the utils ntp status as Brian noted above. However, there are also a number of NTP-related bugs in CUCM 8.6 and higher. I have had several customers with similar issues and it is generally been purely cosmetic. See the following thread, review the bug IDs, and you may consider opening a TAC case as well:
https://supportforums.cisco.com/discussion/11275801/problem-ntp-after-upgrade-and-install-vmtools
Be sure to take a look at Aaron Harrison's recommendation as well in that thread. He always has solid advice in the forum.

V2V to reduce provisioned size of VM while powered-on: How? vCenter 5.5

Unfortunately, VMware Converter does not allow you to do post-conversion synchronizations when shrinking a disk, only when maintaining or increasing the size. This means you would lose all changes that happen after the conversion starts. The only supported way to do this with the VM turned on is using Storage vMotion, if you have that feature.
The sdelete process is actually quite safe when done correctly, but the second part of the process -- removing zeroed blocks from the VMDK -- does require the VM to be turned off when it runs.

So, I have a VM that's grown unnecessarily large and I need to shrink the provisioned size, but I rarely have a chance to power it off. Is it possible to do a V2V with VMware Converter while the VM is powered on and running? The VMDK of the VM in question is Thin-Provisioned currently. I have read this can be done with SDelete, but that is a dangerous route. This a production machine that we heavily rely on, so I need to go the safest route possible. Thank you....

UCS C series 10GB Adapter

Hi,
We are planning to purchase a C210 server with 2 x 10GB NICs, these NICs will connect to a Nexus 5K switch, no other NICs will be used. The servers will run VMware ESX 5.0
What is the best 10GB adapter to use that will allow vNICs to be created for the different ESX vswitches - storage, vmotion, data etc? Will the P81E be suitable or the QLOGIC 8152?
thanks,

For each vswitch you create within ESXi, you will need at least one upstream nic. The QLogic is fixed with 2 ports . The P81E also has 2 ports but can host multiple virtual NICs on these two ports.
http://www.cisco.com/en/US/prod/collateral/ps10265/ps10493/data_sheet_c78-558230_ps10279_Products_Data_Sheet.html
You mention 2x 10Gb NICs. The C210 will only support a single 2-port 10Gb NIC. I suspect this is what you meant but want to clarify the restriction.
