• vSphere high availability 'Élection' fails at 99% 'operation timed out' to 1 of the 2 hosts

  Hello

  We had a system with 1 host ESXi 5.1 with local disks.

  Now, we install redundancy by adding a 5.5 U2 ESXi host and a device of vCenter 5.5.

  After having installed and any addition to vcenter, we went the ESXi 5.1 to 5.5 U2 ESXi. The SAN works correctly (vMotion works on the own NETWORK card).

  Now, if I try to activate the high availability, both servers will install the HA Agent and start "Election".

  All the warehouses of data (4) on the SAN are chosen for the HA heartbeat, response of isolation is "keep it turned on" by default.

  A server will always be this process done, and the other will keep "elect" until it reaches 100% and errors on the operation "election timed out.

  I've seen this problem on both servers, so I think that the 'master' elected does not have the problem, only the "slave".

  I have checked these items and executed, but not worked:

  VMware KB: VMware High Availability Configuration fails with the error: unable to complete the configuration of the ag of HA...

  -the default gateway is not the same on the two hosts, but I fixed that. There is no itinerary changes. HA the setting is "leave power." After correction and deactivation/reactivation HA, the problem is always the same.

  VMware KB: Check and reinstall the correct version of the VMware vCenter Server agents

  -J' ran "Reinstall ESX host management agents and HA on ESXi" agent of HA, and I checked that it was uninstalled and reinstalled during the reactivation of HA.

  CP /opt/vmware/uninstallers/VMware-fdm-uninstall.sh/tmp
  chmod + x /tmp/VMware-fdm-uninstall.sh
  /tmp/vmware-FDM-uninstall.sh

  I did this for two guests. This fix makes the problem of the election and I was still able to run a HA test successfully, but when after this test, I turned off the 2nd Server (in order to test the PA in the other direction), HA has no failover to 1 and everything remained low. After pressing 'reconfigure HA', the problem of the election appeared again on 1 hosts.

  P.S. I had problems with cold Migration during the implementation of the SAN. After setting up all (vMotion, ESX upgrade), these problems have disappeared.

  When you search for this error, I came to this article: KB VMware: VMware vCenter Server displays the error message: unable to connect to the host

  And this cause could make sense, since the server vCenter changed and IP addressing has been changed during the implementation.

  However, in the file vpxa.cfg, the < hostip > and < serverip > is correct (verified by using https://< hostip > / home).

  Tried this again today, no problem at all.
  

  P.P.S. I have set up several of these systems from scratch in the past without problem (if it is an 'upgrade').

  OK, so the problem is solved.

  I contacted Dell Pro Support (OEM offering the license) and they checked the logs (fdm.log) and found that the default IP gateway could not be reached.

  The default gateway is the ip address by default host isolation, used by HA.

  Because it is an isolated production system, the front door provided proved only for future purposes.

  Now, I've changed the default gateway address of management on the switch plugged into both hosts, namely the ping requests.

  This solved any problem.

• 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,.

  Ben.

• High availability of components in the design of vWorkspace tips

  Hi all

  Would ask you some advice regarding the design of vWorkspace components highly available. Suppose that vWorkspace components will be deployed in vSphere or hypervisors managed SCVMM hence HA is in place, if the failure of a host. In this situation, if we still need components redundant (n + 1 VMS) vWorkspace?

  On the other note, I understand that we can add a couple of broker for vWorkspace in vWorkspace Management Console connections and based on KB 99163 it would just work. I'm not sure how the traffic would be when an application is web access? As in, I guess that the connection broker news would be 'defined' at the request of the web call to the broker for connections. Or this is done automatically? Access Web would choose randomly from the broker for connections to go?

  Thanks for any advice in advance

  Kind regards

  Cyril

  Hi Cyril,.

  Big questions. As with any IT architecture in layers, you must plan HA and redundancy at all points of failure required by your environment or level of Service (SLA) agreements. For vWorkspace, the center of his universe is SQL and you must plan accordingly the failure and recovery. In some environments, full backup can meet the requirement of HA. In others, full SQL Cluster, Mirroring, replication, or Always-On configurations may be required. With our broker, we recommend N + 1 deployment in most scenarios HA. When you move peripheral components or enabling, you must evaluate each component and needs its impact of failure as well as its valuation to determine the appropriate AP.

  Load balancing between several brokers is done automatically by logic in the client connectors. In the case of Web access, when you configure the site Web Access in the Management Console, it includes broker list in the Web access configuration xml file. As client connectors, Web Access includes balancing logic that distributes the client load on brokers available automatically.

  If you have any questions about specific components and requirements of HA or architecture, please add them in the discussions.

• The OAM Console in a deployment architecture high availability

  Hello

  I'm looking to implement a HA for OAM environment and read the various docs that the OAM console is deployed on the AdminServer. However, when I read the Oracle documentation on Oracle Fusion Middleware high availability Guide for Oracle Identity and Access Management

  It gives the URL in the console of the OAM as the link to test the server managed, which means that OAMConsole is accessible on the ManagedServer. Is there anywhere I can find a definitive answer on how OAMConsole is deployed and in the what server / cluster?

  Ideally, I'd like the OAMConsole app deployed to the cluster (instead of the AdminServer) in order to achieve for her AP.

  Thank you

  oamconsole is deployed on the AdminServer, and there may be only one admin server active per domain.

  The link that you are referring is on setting up a cluster OAM. Oracle encourages a cluster OAM of 2 instances that are deployed on 2 physical servers. The server administrator is recommended to set up an alias to separate host that they refer as a VIP that is linked to a separate IP as the OAM instance on the same host address. A clone of the Admin instance is then placed on the second physical server corresponding to the second instance OAM. In the case of the first instance OAM and the server administrator is not available, a reconfiguration of network must be made to move the VIP to the second instance. Once this is done, the server administrator can be started on the second server.

  This gives you a little HA/DR.

• VSphere API is available in VMware vSphere Essentials Kit?

  Hello

  TL; DR: I would like to know if the vSphere API is available in VMware vSphere Essentials Kit.

  We evaluated VMware vSphere to build an environment very small test & dev to work. Since vSphere worked well during our assessment, we will buy vSphere licenses.

  We only need to operate a single ESXi host and we don't much care our virtual machines because they are used for testing only. Thus, we don't need features such as vMotion.

  However, take us pictures and we depend on the vSphere API, because we use pyVmomi to administer our virtual machines.

  Because we only run an ESXi host, need for API vSphere vCenter but did not need features such as vMotion, I think that the Kit Essentials fits our needs. But I'm not sure it provides the vSphere API. If anyone can confirm?

  Kind regards

  Yes, vSphere API are available in the Essentials kit.

• High availability without shared storage?

  
  Hi all

  We have created two new 5.1 without any network vMotion ESXi servers and no shared storage. Client asked for high availability of virtual machines. There are few things that we can look at in this situation as FT and HA, but I know that they will not work without shared storage. VSA is also another option in this case, but it is not flexible and has more limitations than benefits.

  Just check there at - there another solution we can us to provide high availability for virtual machines.

  Thanks in advance for the help.

  Greetings

  Nick

  Without storage shared (or ASB), it is difficult to provide high availability. Maybe vSphere replication is an option, if you can accept the loss of the latest changes, when it comes to the last line.

• Infrastructure for high availability

  Hi all!

  Stage en currently, Lun project is to implement Davis high availability vmware to deploy it later.

  After a lot time on the tutorial, I realized to a high availability system, to 2 ESX servers, a minimum en SAN Bay.

  Normal after the Vmotion solution seems to me the best. So that Vmotion works must implement vCenter Server integrated into a field.

  My question is about how many card to pay the ESX servers? According to my research, I AI 3: 1 LAN, SAN 1 and 1, pour Vmotion if I don't me not mistaken.

  Then the question that arises is or place vCenter? Place it in a virtual machine or in physics?

  According to what I've read, the best would be to put it in a virtual machine. So in this case, is it possible to put the DC also in a VM or does is in physics by taking into account the possibility of "unavailability.

  Another question: should Hook the ESX version with a license or a version ESXi is sufficient?

  Thank you in advance if someone would have an opinion.

  Hi Tatuxp,

  Welcome to the VMware forums.

  Pour a DC Windows Virtualization, you can find a lot of info in this document:

  • http://www.VMware.com/files/PDF/Virtualizing_Windows_Active_Directory.PDF

  You can't start a band with the free version of vSphere. You'll have more info in the FAQ:

  • http://www.VMware.com/products/vSphere-hypervisor/FAQ.html

  Pour the network config, it depends on a lot of your physical infrastructure. If you have physical networks separated, it normal morphologies of ports need you two network for redundancy. If you only have one big switch output and you use a VLAN, you trunk ports and you can put your cards in redundancy to each other. You have a good document that presents the main principles of virtual networks here:

  • http://www.VMware.com/files/PDF/virtual_networking_concepts.PDF

  Finally pour your VMs DC, the fact of having two and use rules qualifirons-affinity allows you to always have an available in even if one of the nodes in the cluster.

  Good luck!

• It is possible and effective: high availability (failover) on 2 guests with local storage?

  Hello

  I have a discussion on the implementation of ha (failover) with 2 guests with local storage.

  My advice is to go with a shared storage. But there is another view, use the cluster failover MS with local storage service to save on the shared storage hardware.

  2 "mirorred" on each host machines. Is it feasible at all?

  The HughesNet: have 2 virtual machines (SQL server and server applications in a highly available environment). The workload of the machines will be raised to 2 very powerful servers that are supposed to be buying.

  1. Please briefly explain a feature of local storage to provide HA.

  2. I got to cluster in the virtual environment, not so I guess that the shared storage is used only in the virtual environment.

  Thank you.

  Michael.

  There is software that can replicate a running, physical or virtual machine to another accessible location on the network. This could be as simple that between two close hosted ESXi of VMS or high-speed WAN. Take a look at things like neverfail, doubletake others.  The costs would probably be a bit prohibitive in a smaller environment. It might be possible and maybe even practice to use a virtual storage device having a failover replication. Use of storage on each host and allows to provide the data store. Open-e

  The Microsoft Clustering solution needs a shared storage.

• WLC 5508 high availability

  Hello

  Today I have two WLC 5508 (with license for 100 AP each of them), on a single site.

  The WLC work availability (active-standby).

  However, we have a new scenario, with 02 sites: A and B (attachment).

  I would like to know if it is possible to work as follows:

  The WLC - A as the main controller of site A. WLC - B as a backup (BDC) of WLC.-a.

  The WLC - B that has the PDC site B. WLC - as a backup (BDC) to WLC - B.

  For example:

  If WLC - a falls, site access Points are managed by B WLC site - B and vice versa.

  Is this possible?

  How can I configure the new scenario? Don't forget, there is a site-to-site between Site A and Site b.

  Another point:

  If I add more than 50 APs on Site A. How does the license number?

  Should I buy a license for the two WLC?

  >.. .is it possible?

  No. , high availability in terms of controller is supposed to be what is said, the backup controller is not 'full' - stby and cannot play other roles.

• Deployment of high availability of the IPCC 4.5

  In a future HD architecture implementation, the voice service will provide CallManager 5.0, that will integrate with 4.5 of the IPCC. 4.5 (required with 5.0 CM) IPCC does implement a high availability. How can we ensure that technical support continues to operate if the IPCC goes down? One possibility might be to configure CM such that if the IPCC goes down, all the number of help desk calls are automatically and immediately headed to a group (which includes all extensions help desk). This redirection can be configured in CM? Is there a better option?

  This is your best bet. On the road Points for your call center just put the call before busy, no answer and failure to the fighter pilot. Thus, when the IPCC Express Server is down it will sent to your fighter pilot.

• IPS high-availability Solution

  Hi all

  obligation to have redundancy for appliance IPS placed on data center design, I dug on Cisco docs but found the resilience and the HA (High Availability) from the point of view of IPS could take place in the side of switches (HSRP/Eth channel balance).

  is there a visible way to implement high availability of dynamically!

  Kind regards

  Yes Belal, both of the things mentioned by you are right. There is no function available which allows "failover" communications between IPS two boxes as do Cisco firewalls.

  Yes Etherchannel load balance traffic to each pair of IP from sensor single src - dst.

• SNS with high availability option

  I need help to understand the requirements of network and connectivity to deployment Cisco show and share with the high availability option where the DC and DR are different geographical locations.

  As I understand it, to achieve high availability, the DMM and the SNS servers require a L2 connectivity between the primary and the secondary server. How can this be achieved in a scenario where two data centers are connected by WAN / MAN links?

  Hi, Datar,

  I already asked this question to the TAC, and it is unfortunately clear today the HA mode with 2 servers connected mode "back to back" via Ethernet2, REQUIRES to be on the same network of L2.

  It is not yet based on the IP routing layer, and therefore it is did not in charge of the design when using remote data centers...

  :-(

  It's a shame, I know, and I pointed to the BU of the SnS.

  May be part of a next version of work will be based on network IP L3 routed...

  Wait and see.
