Re: VM data consumption on vSAN Storage

Hello andvm

 

 

"To keep with the same example let's say that the LUN will be of 1.5TB, will the vMotion allow the migration since the VM vmdk would show as 2GB (since stored on vSAN)?"

 

Did you mean to say 2TB? (when stored on vSAN with FTT=1,FTM=RAID1,OSR=100)

When you choose the destination SAN storage it will only be half the size, e.g. the size of the disk as seen by the Guest OS/size as provisioned.

 

I have noted on occasion things like Veeam saying a full back-up of the Object/VM showing the size it will be being the size as used on vsanDatastore but this was just cosmetic, e.g. before backing up it stated it would need 2TB but only used 1TB.

Hi All,

 

Running Horizon 7.4 all the way around and having a connection issue with any device running over 4G or any cellular device. i can connect to all desktops only with Blast protocol but that doesn't bother me too much.  Can't figure what be the issue with the cellular data.  Anyone have a clue where to start with this one??  Any help is appreciated.  Thanks

FC zoning Windows server into configuration when there are ESXi hosts present

August 24, 2018, 3:50 pm

Hello,

 

We have a FC SAN using 2 brocade switches/fabrics. Currently we have 10 ESXi hosts using FC SAN.

The ESXi hosts HBA ports and SAN controller ports are zoned together and we serve datastores via the provisioned LUNs after mapping the LUNs to the hosts.

 

I now must connect a single Windows host to the SAN temporarily.

I am worried about creating a zone containing the windows HBA ports and the SAN HBA ports for fear of the Windows host being able to access the ESXi LUNs.

I am quite sure things will be fine as long as I do not explicitly map the ESXi datastore LUNs to the Windows host.

 

Am I correct here in my assumption that unless I explicitly map the ESXi datastore LUNs to the newly added Windows host, the Windows host will not be able to harm the ESXi LUNS?

 

To be clear, there is no automatic mapping group for new LUNs, we control it explicitly.

 

Thank you

Yes, if your Windows host is not zoned to "see" the same LUNs being presented to ESXi hosts you're fine. VMFS is cluster aware whereas Windows doesn't understand that.

Re: vSAN Health: Failed Overall disks health

Hello Fabio,

 

 

"that after an hardware reset on all the disks of a node,  the vSAN has put the diskgroups, hosted in this node, in the failed state."

What model of controller and what driver+firmware in use? (and if any variant of H730P - do you have any VMFS/logging/dumps going to disks on same controller?)

Are you seeing a lot of 'Power on reset' messages in vmkernel.log and vobd.log? Are you seeing reset sense codes (H:0x7)?

 

"How can I active  the failed diskgroups?"

Are the disks out of CMMDS? If yes, have you tried unmount + remount of the failed disks?

 

"The vms are working and it seems that there are no objects in error and I do not find objects hosted on diskgroups in the failed state."

Yes, as all the data would have been rebuilt on the remaining nodes and if the disk-group(s) are still marked as failed then it isn't going to place any data-components on these.

 

"I thought of trying to put the node in maintenance mode (trying to evacuate the data but it should not move anything because the diskgroups were in error) and then a simple node reboot  to see if it active the diskgroup everything."

If all the data from this node has already been rebuilt elsewhere then placing this in MM with 'Ensure Accessibility' and rebooting it isn't going to negatively change the data availability, so yes do perform this.

 

"I opened a call to the support but they are analyzing the logs for a weeks. Until today no news"

Sorry to hear that, can you PM me the Support Request number?

Hi

The installer in the version PT I do not know.

Try this:

If you want to change Workstation UI to PT, you can open Windows Control Panel, open "Regional and Language", and change format to "PT-BR".

Re: Workstation Player 14.1.3 on Unbuntu, Poor Performance and Freezes Windows 10 Guest, 3D Acceleration

Sorry about that I gave you wrong information. I mixed up VMware Fusion on macOS capability with that of Workstation/Player on Windows/Linux. On Fusion, a Windows VM would have a virtual USB camera and the camera of the Mac hardware didn't have to be connected to the VM.  I have a laptop with Intel RealSense but I haven't tried connecting it to any VM for facial recognition. It appears as multiple devices on the Windows 10 host Device Manager but appears as just a single Intel composite device in the VMware USB connect menu. Anyway, you could try connecting webcam to the VM but I would think you would need to install the 3D/IR drivers of the camera into both the Ubuntu host and the Windows VM for the facial detection. But I suspect if it appears as just a single device in the VMware USB connect menu, it may not work at all. I haven't spent any effort to try to get the facial recognition of Intel RealSense to work on a Windows VM.

 

As for the DisplayLink USB dock, it looks like DisplayLink has driver for Ubuntu 16.04

 

http://www.displaylink.com/downloads/ubuntu

 

My workaround to avoid the freezes with the Windows 7 laptop several years ago with the DisplayLink adapters was to restart the laptop during my lunch break at 12pm otherwise inevitably it freezes sometime between 12:30pm and 1:30pm; but even then this was not foolproof as sometimes it still freezes around 3:30-4:00pm despite having the mid-workday reboot. Back then, I get the impression DisplayLink does not seem motivated to fix the problem (assuming it is some sort of DisplayLink driver issue) as their business model seem to be to sell to the OEM. So if the larger chunk of their revenue/profit is attributed to the OEMs, consumer complaints about the freezing may not get proper treatment unless the OEMs complain. I haven't used the DisplayLink adapters for a while now (stopped using them early 2014) so I have no idea with regards to the stability of their drivers now to use them nonstop for a full work day.

 

You may also want to look at this

https://support.displaylink.com/knowledgebase/articles/1859356-x-server-crashes-on-nvidia-systems-when-displaylin

 

Not sure if you can take this KB an encouraging sign. But in 2012/2013, DisplayLink didn't seem interested at all in fixing the freezing problems.

 

As for using ESXi, you would need at least two physical (or virtual) machines. One to host the ESXi and the other machine to access the VM(s) running in the ESXi. Of course you can create an ESXi as a VM and still have more VMs running inside this ESXi VM and you could have this setup in all just one laptop (this is when the virtualize Intel VT-x/EPT is needed). Running ESXi probably isn't the solution as it just add another layer of complexity for you and if you want good video capability inside the VM, ESXi can't provide that without GPU passthrough but that is another topic in of itself.

No problem. The facial detection isn't a huge deal anyway.

 

About an hour after writing that resoonse, it froze up again, and then all my external moitors we're no longer recognized. Then I powered down the VM....and the whole machine locked up.   

 

Thanks for all your help...but thinking of abandoning this. The daily ongoing annoyances and lack of performance are probably not worth it compared to the pain of rebuilding my environment annually.

SupreetK,

 

Thank you!  I couldn't find these instructions with my countless google searches.  I saw the 4.5.3 on the driver page but another page referenced 1.6.5 for use.  Thanks again!

Just to give a little more detail here since I forgot to include it earlier. Windows seeing a LUN formatted as VMFS isn't in and of itself a problem, it's only when it tries to do something with it that can be catastrophic. By default, automount is turned on for Windows in which case it will try to mount any new disk it sees. This can damage the filesystem and for that reason presenting it should be avoided. However, there are cases where this is not only *not* harmful but actually required. An example being backup software (which will disable automount) that has the capability of reading and extracting data from VMFS. If this doesn't apply to you or you aren't sure, err on the side of caution and simply do not zone it in.

Try an earlier version. 4.5 is for use with later vRA versions. There have been reports of small bits and pieces not working when using CC of more capabilities than vRA.
