vSphere HA failover in progress

• not triggered alarm not: insufficient vSphere HA failover resources

  This alarm is only triggered when a HA action fails?  I have a cluster of two hosts ESXi 5.0, and since I'm on more than 50% of available memory on each host, for me, it seems that I can't tolerate a single host failure.

  

  HA and DRS are enabled on the cluster, and the "admission control policy", I have 'percent of reserved failover cluster resources', set at 50%.

  So why no alarm?  My goal is to get an alert before to reach the State we begin, where we cannot tolerate apparently not a failure of the host.

  > Based on this and the absence of the alarm, we can assume that if I dropped one of the hosts of this 2-host cluster, all the virtual machines would be able to start on the only host remaining, correct?

  Correct, if one of your guests crashed or zero all your VMS would have sufficient resources to start (no guarantee of performance, just start/running)

  > And the alarm, I want to talk to the title of this thread only is triggered when what 98% to 50% or less, correct?

  There's no alarm. When your ability to failover CPU or memory reaches 50% admission control will prevent you from turn another VM

  > I am still concerned about the diagram of distribution of this resource for memory, however. It looks like I could push up to 100% on both hosts and still no push failover memory less than 50% capacity. I guess that this is due to the fact that my virtual machines have no memory reserved, so vSphere counts only the minimum amount of memory to start the virtual machine, and it will depend on permutation and balloon so all virtual machines start actually using all of their memory.

  Fix

  > So the alarm I'm looking for is the one that reproduces the table of distribution of resources and alerts when the total unused memory in the cluster is less than the total memory to a single host.  Make sense?

  I'm not aware of an alarm like this. You may be able to find something through google or create something yourself. On the creation of reserves for your virtual machines? Or less the most important? This way you can ensure that they will get resources when they restart. Or if you really want you can replace admission control by hosting dedicated failover policy? (I do not think that I recommend with what I know of your situation, but it will give you what you ask for).

  Have you watched the vRAS fling? VM and Service availability & #8211 resources; VMware Labs

  This adventure allows you to perform a host on your infrastructure failure analysis. You can simulate the failure of one or more hosts in a cluster (vSphere) and identify how:

  • Virtual machines will re-start safely on different hosts
  • Virtual machines would not be restarted on different hosts
  • Virtual machines would be the degradation in performance when rebooted on a different host

  With this information, you can better plan the location and configuration of your infrastructure to reduce the downtime of your virtual machines / Services in case of failure of the host.

• Vsphere-Windows failover cluster replication

  Hello

  Need help to replicate Microsoft cluster at 2 knots.  I know that vSphere replication is compatible with virtual RDM so will change to virtual RDM physica, but the controller SCSI ROW of nodes have buses sharing (Physics) is enabled. How to reproduce these groupings with SCSI bus sharing enabled, since vsphere replication does not support sharing of bus

  Thanks, waiting for some thoughts/work around

  vSphere replication doesn't support MSCS, see: KB VMware: vSphere Replication FAQ

  Is VSphere replication supported MSCS clusters?

  vSphere replication does not work with virtual disks open mode "multi-writer". Virtual machines MSCS cluster are configured with virtual disks open mode "multi-writer", so vSphere replication will not work with MSCS configuration.

• Configuration of high availability in vSphere alarms

  Hello

  We have three ESXi hosts in a cluster and, recently, one of the hosts that failed (I have connected a matter of pension with VMWare to get assistance to research into why).  The virtual machines on this host automatically migrate to the other two hosts in the cluster, but we did not know that this had happened until we saw some VMS showing high CPU ready using vCOPs.

  My boss asked me to alert us if the high availability feature is used as it was the case here.  I looked on Google and the VMWare Web site, but I can't find anything specific but I've only worked with VMWare products for about a month so it could well be that I'm looking for simply not the right thing.

  I would be grateful for any help, as I have said that I am very new to VMWare, so I hope I got all the information that is needed, if it's not made me know.

  See you soon,.

• failover of machine virtual vSphere HA failed

  I get this error on all my VMs on host I restarted management services on.

  I essentially ran /sbin/services.sh

  so spend and vpxa were restarted

  But why my vms are getting these errors?

  Yes, at the level of vCenter, go to the definitions of the alarm, select definitions for vSphere HA failover the virtual machine has noalarm, click alarm to edit, disable the alarm click OK... then fade all the alarms, then change the alarm again and click Enable, then click OK.

• Deep security virtual appliance Micro trend and configuration HA

  Hello team,

  A virtual appliance deplying step of deep security Trend Micro is to disable cluster HA... can you please explain what is the reason to turn it off?

  If you run this step and try to reactivate the HA... vCenter will give you an error message that there is not enough vSphere HA failover resources.

  Thank you

  Mohammad

  I don't want to turn off HA, I suggest that the power of the virtual machine on parameters being the default per HA, new virtual machine that does not meet the requirements of the HA does not fit the power on.

  Right-click on the cluster > ClusterFeatures > HA vSphere > select Disable: 'allow the VM Power on operation that violate constraints of availability.

  This could be a problem of vSphere?

  Cannot be the problem of vSphere. But this is a feature of vSphere.

• who can help me with "insufficient resources to meet the level of failover configured for vSphere HA.

  Hello world

  We tried to gif a 14GB of ram and make server complete a booking for her.
  This is a server for the exams and the vendor told us to do.

  I can't any more then 5500MB reservation on it, when I anymore that I get
  "Insufficient resources to meet the level of failover configured for vSphere HA.

  We have:

  2 X 5.1 ESXi hosts
  Each host has
  2 x processors (8 Cores each) with HT active.
  255,75 GB of Ram

  vSphere HA has been activated.
  Admission control policy is enabled and that the ability to failover is 1 host.

  What is the problem here?

  Thank you
  Ernst.

  
  

  Admission control policy is all about to give you the kind of guarantee that if the host failure happens then there will be enough resources to perform the successful failover.

  in simple terms, it comes to reserve the resources of failover.

  I would recommend going through the notion of vSphere HA, reduced control policy the following document.

  https://pubs.VMware.com/vSphere-60/topic/com.VMware.ICbase/PDF/vSphere-ESXi-vCenter-Server-60-availability-Guide.PDF

  From the Page number 22, the details that you need to study is given. Focus especially on part calculations Slot size of it.

  in your case you HA vSphere with number of failure of host to tolerate as admission control strategy defined.

  This means system will calculate CPU and memory slots out of the resources in your cluster, and the total number of units, it will keep some resources like reserved for failover, and others will be available to be used. It all depends on how much failure of hosts that you want to tolerate.

  now in your case, if you try to increase booking one of the virtual machine, which will then affect the number of locations in your environment, and so reserved ability to failover is violated, the system will not let you do what you want to do. As the energy on a virtual machine, or growing booking a powered VM etc..

  If you find that you have enough resources in your cluster and due to some virtual machines with very large cpu or memory reservation, number of places is less than you can still manage the settings some advanced in vSphere HA configuration, but I strongly recommend, try to take the help of someone who has done it before.

  also try to go through other admission control strategies which are explained in the document for more inputs.

• The virtual machine failover and restart with vSphere HA time

  Hello

  What factors would affect the time required for vSphere HA to computers failover virtual to a host failed to another active host in the cluster? It would be important how much space drive by using virtual machine is or how big it is? Or who should not matter?

  Thank you

  It should not matter. HA initiates the failover and the powers on the virtual machine regardless of size. Note, however, that there could be a delay in time OS/App.

  Another parameter that can affect the failover time is the number of virtual machines being switched at some point. If you have more healthy hosts in the cluster, then VM failovers happen simultaneously reduce the failover time.

• vSphere Standard switch - how does the failover

  Hello

  I have a theory for you question VMware guru.  I have four ports on my ESXi host and I want to assure you that in the case of a link failure, network traffic gets moved to another link.  Currently, I have all four adapters marked as Active to balance traffic between the four ports to load.  My question is, what is the point of having an auxiliary card?  In the case of a failure of the link, is it a switchport not active failover to another active port?  If an active port can switch to another active port, why would you want never to define an interface in sleep mode, rather than use it for balancing traffic?

  Thanks for any idea in advance!

  -ToTheCloud

  OK, so the auxiliary card would be useful if I only had 3 ports and two switches vSphere Standard.  At this time, when a port to one of these switches would fail, I'll be able to have the one of these switches switch to auxiliary card (since you cannot have an active adapter on both switches at the same time)?

  Correct - if you had two vSwitches, each with a NIC card Assistant could only be assigned to a vSwitch both.

  Also, just to clarify, if I do not have all four active cards on the same vSwitch, if a link goes down, traffic would failover to another active adapter if I didn't have a correct map specified, auxiliary?

  Yes.

• ESXi 5.1 - insufficient resources to meet the level of failover configured for vSphere HA

  Hi, I tried to understand why there are insufficient resources to supply an only little VM in my vSphere cluster.

  2 X 5.1 ESXi hosts

  Each host has

  2 x processors (8 cores each) with HT active

  192 GB OF RAM

  vSphere HA has been activated.

  Admission control policy set to "tolerate failures of the host in the cluster" with the value 1.

  With 2 GB of vRAM and 1 vCPU has created a virtual machine.  No memory and CPU Hotel booking.

  I put one of the host in maintenance mode and try to turn on the virtual machine, but it failed to power upward with the error "insufficient resources to meet the configured switch level for vSphere HA.

  Am I missing something?

  Thank you

  Alex

  I put one of the host in maintenance mode and try to turn on the virtual machine, but it failed to power upward with the error "insufficient resources to meet the configured switch level for vSphere HA.

  When having two hosts only no host doesn't stay for failover when one of these hosts are in maintenance mode... That is why it gives you this message...

• Not enough resources to meet the level of failover configured for vSphere HA

  I have a cluster of vSphere based 5.0 based on ESXi 5 knots 2.

  When I try to start a virtual machine, I get an error saying that there is "insufficient resources to meet the level of failover configured for vSphere HA.

  If I turn off an another VM the problem disappears and I can turn on my VM.

  If I try to turn on the virtual machine, I have already turned off, I get the error again.

  It seems obvious that there is a lack resources or some setting is misconfigured, but even after reading the forums and manuals, I am unable to locate the critical resource or parameter that is not correct.

  Based on my experience or vSphere server and ESXi servers are overloaded.

  I have an another similar cluster of hosting a larger number of virtual machines with no similar problem.

  This performance counter and this setting should check to identify the bottleneck?

  Concerning

  Marius

  To check reservations for virtual machines, I would select the Cluster in your vCenter inventory, then select the resources"" tab.  Which displays the child objects of the bunch (VMs, Resource Pools, vApps).  There you can watch settings of CPU resources and memory.  You'll want to watch the column of "Reserves".

  To find the size of the slot and places available, look at the tab "Summary" of your cluster.  There is a tile marked "vSphere HA.  In this mosaic, there will be a link for "Advanced Runtime Info" which will open a new window with the location information.

  When the Admission AP policy is set to "Number of failures of host cluster will tolerate", HA has a very pessimistic view of your resources, since it must be able to handle all the possibilities.

  Another option would be to change the admission control strategy in settings of Cluster HA to "percentage of resources reserved for failover.  It reserves a part of the resources for use by HA in the case of a failover, rather than trying to calculate the size of the individual virtual machines.  With a 2 cluster nodes, I think it a relatively safe bet to set these values to 50%, as your worst case scenario HA would be losing a single host on 2.

• Don't vSphere replication create control points which can be selected during the failover?

  Don't vSphere replication create control points which can be selected during the failover?  Or is the latest version of replication, the only option to failover?

  Thank you

  -MattG

  No, this isn't

  You CAN do this with EMC RecoverPoint (although not on a per VM level).

• vSphere HA Virtual Machine failover failed

  Hello

  There are 3 ESX host in our cluster.  One of them (say Host3) just out of the Maintenance Mode.

  Then we change the DRS to aggressive and run reconfigure HA on the other hand, two ESX host (let's call them Host1 and Host2).  We just want to migrate VM to ESX host that just come out of maintenance mode.

  However, we find that all VM on a particular of ESX (Host1) host and a VM on a different host ESX (Host2) get the error message "failure of vsphere HA Virtual Machine failover.  We would like to ask for your opinion what are the possible causes of this error message?  The parameter that controls the behavior of the cluster?

  Thank you

  Nice day

  It looks like no HA should be launched at all in your situation as long as there are no unexpected host outtages.  You have followed VM enabled in your settings of cluster HA?  You'll definitely want to check the logs of the evidence as to why this is happening.

  Make sure that each of your hosts can ping address their isolation, usually the default gateway of the management network.  If you have followed VM enabled, make sure that VMware Tools is running in virtual machines that had the error.  You can also disable HA on the cluster and wait that AAM agent to be uninstalled from each host, then re-enable HA.

  If you don't want to disable all of the HA cluster, you can also remove individual hosts to vCenter.  This will also uninstall the agent of the MAO.  Once it is removed, add back to vCenter and the cluster HA-enabled.  This will then be re - install the agent HA.

  Without looking at the logs, it is difficult to say exactly what has caused your problem.  Feel free to attach your files to log to the community here.

  See you soon,.

• Network [vSphere 4.1] load balancing and failover vMotion

  GoodMorning everyone.

  I have some doubts about the configuration of the network for vMotion in vSphere 4.1

  I know that I can activate a single portgroup VMkernel for vMotion on the single host, but can I have this portgroup in a vSwitch with two or more physical NIC attached.

  Currently, I managed to have a vSwtich with vMotion and management of trade wth two NICs (see attachment).

  Both NICs works very well with the recovery for both exchanges.

  I would switch to a vSwitch with multiple network cards and I have some doubts.

  It seems that I could configure it... but the load balancer for vMotion supported on vSphere 4.1?

  And also, have the protgroup of vMotion in a switch with several network cards, is there a way to check what physical nic is currently used by vMotion?

  I am currently under a license from the company.

  Thank you all for your help.

  vMotion for vSphere pre 5 does not support Multi-NIC, in vSphere 5, you can configure several VMKernel enable vMotion and select different Nic Active and load balance between the two vmnic, but unfortunately not in vSphere 4.x

  For the management of ESXi, if you set active on both network adapters, you not to cross any active advantage / standby because it will only use on vmNIC, unless there is still a failure... but 1 vmNIC just because bandwidth is usually not a problem for the ESXi management only.

  So the answer: upgrade to vSphere 5 for multi-nic vMotion and don't worry ESXi management as an active NETWORK card is more than enough bandwidth,.

  Here's a YouTube on the Multi-NIC vMotion http://www.youtube.com/watch?v=7njBRF2N0Z8 configuration
