Difficulties to remove ESXi 5.0 cluster hosts

• ESXi 5.1 cluster moving to new hardware

  I have a 5.1 ESXi cluster consisting of 2 servers of Sun I want to retire - Sun #2 is the best of the 2 servers.   I all 2 new Dell R620 stretched upward, wired and pre-loaded with 5.1 U1.  My license is for 4 and vCenter is a virtual machine in the cluster, I want all moved to new hardware with little or no interruption of service.

  This would be the way to go?

  1. set up Dell and storage server configuration networking properly (I am comfortable with this part).

  2 migrate all virtual machines to Sun 2.

  3. close the Sun 1 and remove the cluster

  4. Add 1 Dell to the cluster

  5 move the VM to Dell 1

  6. switch off the Sun Deceiver 2 and remove the cluster

  7. Add 2 Dell and move virtual machines as you wish.

  Sun servers were not identical, then the VCA mode is Intel "Penryn".    The specs say that future Intel processors can join to this group, so it is not a problem running 1 Dell and 1 Sun temporarily, correct?  The r.620 are the same, so as soon as they are both in the cluster can / disable CVS mode?    I have to restart each VM later so he would see the new processor features, correct?

  Is this what I need to look at.

  Thanks in advance for your answers.

  You can do a lot of ways, but I would recommend not to remove the beam #1 sunlight until you are 100% made to the migration. Which leaves you exposed from the point of view HA (assuming that it is production, since you want little downtime), and is an unnecessary step. RELATIVE to the issuance of licenses, since this is a migration of right, keep the r.620 in eval mode and change the licensing of more later. Which allows to rotate the environment MUCH easier.

  Here's what I'd do (emulation of your list)

  (1) Networking Setup / storage on r.620, to be compatible with the old SUN servers.

  (2) to present the cluster r.620

  (3) to migrate a low priority / test VM networking, testing vMotion and new hosts.

  (4) to migrate most of the virtual machine the new hosts.

  (5) migrate vCenter last VM (just to be safe)

  (6) put SUN 1 and 2 in maintenance mode. Leave them in the cluster for a few days just in case

  (7) remove SUN 1/2 cluster once everything works well, remove the former hosts of vCenter and closed. Clean a network configuration and storage, respectively (be careful here).

  (8) stimulus EVC Mode at the highest level appropriate (Sandy Bridge, I guess).

  (9) it is important, read closely. If you want to increase the level of CEV, after former guests are completely gone and dead, completely off each VM, a power back on. This will raise the functional level of CVS to the new level. Simply restart the guest OS won't do it. You can check by going to display hosts and clusters > VMS > add column EVC.

• Tearing the ESXi and VM live hosts to 4.1 and falling in vCenter environment 5.1

  Hello

  Can I please perform the following before the people here to get opinions on how you think it may be...

  Basically, I'm planning a 5.1 vCenter vCenter 4.1 facility upgrade, but I'm not eager to upgrade in place due to my being uncomfortable with the 4.1 - > 5.1 upgrade instability.

  Instead, I built an environment vSphere fresh 5.1, including:

  SSO
  The inventory service
  UU.
  vCenter
  Web client
  SRM

  And he works with the internal certificates.  SRM has been integrated, data centres have been created, OS customizations are in place, empty clusters have been created with the same level of CVS, licenses have been imported and everything looks good to go.

  The next part is to import all hosts ESXi 4.1 of their existing DRS, HA, cluster EVC, which is also protected by SRM.

  However, the problem is that this must be done without interruption for the hosts or virtual machines running.  All NFS stores running the virtual machine.

  So my plan is:
  Unprotect all SRM protected virtual computer (to remove SRM placeholders in NFS and placeholder VMS in vCenter)
  Reconfigure the deactivation DRS clusters, HA (with CVS)
  Remove the cluster (guests will return to autonomous? VM will continue to operate?)
  'remove' host of the old vmware vcenter
  Add a host new vCenter
  Add the host to the cluster again
  Configure the SRM

  I can see from google, that other people have already done, but this doesn't sound sane?

  I want to avoid at all costs, downtime for the VM to place guests esxi in maintenance mode is not really an option.  So I need to check that the above is possible, and that the removal of the cluster will not stop the running virtual machine or to force some kind of hardware installation/panic on the virtual machine because of the VCA mode not more be applied. The VCA mode would be a big problem trying to admit the host/vm to the new cluster if the virtual machine have re-detected hardware of newer CPU...

  Thanks in advance,
  Rob.

  You don't need to remove clusters or move the hosts off the clusters before you attach them to the new vCenter Server!

  We have made the migration in the past (to a vCenter server to another) without this step and it worked fine.

  In the new vCenter server, you can also directly add hosts to the cluster.

  It works very well... unless you use the distributed switches! It is still possible, but requires additional steps.

• Cannot add cluster hosts

  I'm done with this...

  It started when I had to change my non routable IP addresses management network to my private IP addresses.  I kept getting errors with the host, not the new IP address.  I solved this problem, but now when I try to add the hosts again in my group, I get an error:

  "A general error has occurred: passwd: error immediate criticism-abandonment."  blah blah blah stack of error: "unable to set the account VIM on the host, could not set the password. It is possible that your password does not meet the criteria of complexity defined by the system. »

  It is ESXi 5.5u3, I tried the following:

  Remove the vpxa account, restarted host - same mistake

  Restart the services vpxa - same mistake

  Restart the vCenter - same mistake

  VI etc/pam.d/passwd: N0, N1, N2, N3, N4 - same mistake

  VI etc/pam.d/passwd: n0=-1,n1=-1,n2=-1,n3=-1,n4=-1--meme error

  Checked the system authentication, do not know what its supposed to look like, but both hosts match

  For the life of me, I can't understand it and Google has basically the same steps that I have just listed, I don't want to really blow the configuration and reinstall, but he is looking to get down to that... unless someone here knows where else the complexity of password or criteria for the system is set up...

  Fixed the problem myself... Thank you!!

  Action taken:

  Removed the vpxa account - I don't really think this has no effect on the issue

  Retirement services - did nothing until I've known really

  After coming home and watching my esxi, pam.d file hosts and comparing the differences, I just on a hunch deleted after /$ISA / pam_passwdqc.so, then re-entered the information as it was on my host at home.

  SSH in hosts:

  cd\ etc.

  PAM.d cd\

  passwd VI

  My hosts had /$ISA/pam_passwdqc.so retry = 3 min = disabled, disabled, disabled, disabled, 7.7

  My hosts at work had /$ISA/pam_passwdqc.so retry = N N0, N1, N2, N3, N4

  I edited the line to reflect the password of 14 characters required and the value of the retry N, so it looked like this

  /$ISA/pam_passwdqc.so retry = N min = disabled, disabled, disabled, disabled, disabled, 14

  : wq

  output

  Restart the services, actually I rebooted the host, then add in vCenter without problem

• Cannot delete Cluster hosts, no. active HA/DRS.

  I created a Cluster in a vSPhere lab system and adding that a host forgot to activate vmware EVC. One of my hosts vSPhere 6 added to the cluster, which is fine, but it's not the same processor and necessary VCA allowed the vsphere host migrations. There are only 2 guests, both in the cluster, but I can not migrate between them because CVS is disabled. I can not put the host principal in Maintenance mode, because it hosts the VSA vCenter. It is a semi production, so I could stop the for re - setup, but I can't seem to find a way to stop all virtual machines, including the VSA vCenter and delete the host in the cluster?

  B

  You can try the procedure below

  1. create another new cluster to VCA

  2. on the hosts, do a right click-> connection-> disconnect

  3. on the hosts, do a right click-> Remove Inventory

  4 Add hosts removed on the new cluster where VCA is activated.

  Please note that the ID of the virtual machine may change, but the VM will be operational. Hope this has solved your problem

• "Mem.Usage.Average" against the total aggregate of cluster host memory

  Please see the attachment for the whole story.

  Please give me a sanity check on this. I used the "Mem.Usage.Average" as a % against allocated VM MemoryMB. The sum of these calculations escaped by far the actual calculations of the vCenter % memory-based. So, I changed my calculations that you see in the worksheet to use the 'Mem.Usage.Average' against the total aggregate available on all hosts in the cluster. This amount came to less than 1% of my calculations based on vCenter GUI. Am I right against the total aggregate memory cluster host instead of against VM memory assigned using 'Mem.Usage.Average '? Thxs-

  

  SDK is not clear on "total configured memory available or". https://www.VMware.com/support/developer/converter-SDK/conv55_apireference/memory_counters.html Part description of memory used as a percentage of the total configured or available memory.

  
  

  $start = (get-Date). AddDays(-5)

  Get-cluster-location ActualClusterName | Get - VM | Where {$_.} PowerState - eq "Receptor"} @{N = "Mem.Usage.Average"; E = {[Math]: round ((($_ |))} Get-Stat - Stat mem.usage.average - start $start - $finish - IntervalMins 1800 - MaxSamples finishing (250) | Measure - Object - average value). Average), 2)}}"

  
  

  Cluster is 6 hosts with 128G per host for total of 768G (786432 MB of RAM), there are 118 powered on virtual machines

  
  

  
  

  for me the SDK says that percentage reflects the relationship between the memory 'active' in the virtual machine against the memory configured for the virtual machine.

  A configured with 8 GB of memory virtual computer that has 'use' of 25% is actively using 2 GB of memory.

  

  I think that your numbers you get for VMS are biased because of the great period of time during which you take the average (see previous answer).

  You can cross-check the mem.usage.average with the mem.active.average.

  In the following code, I calculate the different 2 meters actual memory used by the virtual machine.

  $clusterName = "mycluster.

  $stat = 'mem.usage.average ','mem.active.average '.

  $vm = get - Cluster - name $clusterName | Get - VM | where {$_.} PowerState - eq "Receptor"}

  $stats = get-Stat-entity $vm - Stat $stat - Realtime - MaxSamples 1

  $stats | Group-object - property {$_.} @entity.name} | %{

  [PSCustomObject] @ {}

  VM = $_. Group [0]. @entity.name

  MemoryMB = $_. Group [0]. Entity.MemoryMB

  MemUsagePerc = $_. Group | where {$_.} MetricId - eq "mem.usage.average"} | Select - ExpandProperty value

  MemUsageMB = [int]($_.) Group [0]. Entity.MemoryMB * ($_.) Group | where {$_.} MetricId - eq "mem.usage.average"}). Value) / 100

  MemActiveMB = ($_.) Group | where {$_.} MetricId - eq "mem.active.average"} | Select - ExpandProperty Value) / 1 KB

  }

  }

  The result shows a specific virtual machine, these two numbers are close enough to be considered the same imho.

  That they should be in fact, the mem.usage.average is derived from the mem.active.average.

  

• Map storage IBM to Esxi 5.1 CIFS host

  I am a beginner with vmware, I just want to know is it supported for mapping a CIFS storage ESXi 5.1 IBM host, then use it as a data store for place of the virtual computer.

• Storage shared between cluster hosts

  Hello

  I have a number of hosts managed under a VC server clusters. I want to downgrade the ESX 3.5 cluster and spend all my virtual machines to my vSphere cluster. I intend to move the storage currently used by ESX 3.5 clusters as well.

  Is this OK (or supported) or even possible for me to do the following?

  1. attach the storage used by the cluster cluster vSphere ESX 3.5 (so it is folded in TWO clusters).

  2. the servers from ESX3.5 to vSphere vMotion cluster cluster.

  3. turn off the cluster of ESX 3.5.

  I guess it boils down to two questions.

  1. can you be shared between host cluster storage two?

  2. If you can, is it possible to vMotion between cluster hosts, assuming that all the vMotion compatibility checks are successful?

  If the above is not possible, I'm guessing that a V2V of VMS ESX 3.5 would be the way to go, and I have to find new storage for the cluster of vSphere.

  Thank you

  Hello

  If you have a SAN vSphere-taking in charge, so there is no problem.

  According to the CRA on your 3.5/vSphere ESX CPU hosts, you might have problems with storage vmotion/vmotion. One way would be to enable CVS, however requiring all virtual machines to be powered off.

  But present the LUN 3.5 4.x guests and make a svmotion is not a problem if you have taken care of storage. (www.vmware.com/go/hcl).

  Then you can just vmotion (if you do not have CPU incompatibility) virtual machines to new hosts, or stop and move.

• Remove ESXi hosts to vCenter Cluster host even

  Hi all. Depending on the subject, I would like to remove the host from an old Cluster vCenter which is no longer accessible because the database is damaged. Unfortunately I can not not to restore it because my predecessor scheduled backups. How can I do? Thank you all in advance for your answer.

  All the information you have provided, I suppose there could be something in the ADAM database, which must be deleted / reset.

  The assignment of license keys is stored in the ADAM database (rather than in the vCenter Server database) and with the new installation of server vCenter on the same host (old) this may not have been reset. Please take a look at http://kb.vmware.com/kb/1015268 to see if this KB will help resolve the issue.

• How to remove ESXi host of Distributed Switch

  3 Cluster DRS - 1 x physical, 2 nested nodes in a LAB environment

  I need to downgrade a 6.0 U2 ESXi host and replace it (from ESXi nested in Physics). I am trying to remove the host from a distributed switch, but it seems that I can't do that until I remove it from the Distributed Switch. I can't remove the VMkernel group management ports that prevents me to remove the host from the Distributed Switch. Any suggestions? I guess that I need that migrate to a Standard switch first?

  I am connected to the ESXi host through vSphere Client, migrated the group management to a Standard switch ports, then I was able to clear the host of the distributed switch. I could then remove the host from the Cluster.

• Thinking on upgrading ESXi 4.1 to 5.0 in a cluster host

  Hi all

  I have the cluster:

  vCenter 5.0 and many hosts running ESXi 4.1

  I want to improve the hosts to 5.0.

  My question:

  There's a question if I do an upgrade offline (using the ESXi installation CD).

  -How about if I want to do a new install of the host? Should I remove the host first of the bunch?

  -Can I migrate the virtual computer first off the coast of the host for both methods?

  Thanks in advance.

  Fajar.

  If you have multiple hosts in the cluster, you can pass the host one

  -Put a host into maintenance mode, that you plan to upgrade, then all the other virtual machines will have to migrate to another host (without interruption)

  -If you are installing freshly host, always the data store you won't get in shape, therefore inherited vmfs3 features will be there, even without the existing data store.

  -No need to turn off the vm or host for migration, go with vmotion functionality.

• How to remove Cluster hosts in vCenter

  We have a VMware vCenter 5.5 license that is about to expire, and while we re-new the vCenter license, I have to take all the VMS that are associated with a group called:

  Orlando (site) > staging (cluster) > 10.1.1.13 (home) > testbox1 (vm)

  I need to remove the (host) (cluster) above. I can do this by typing "Mode of Maintenance", which then moves the (vm) to another host in the staging (cluster). Problem is when I go out "Maintenance Mode", (pole) is placed in staging and the virtual computer is moved to the staging (cluster) > 10.1.1.13 (host). This is NOT what I want. I want to delete all hosts in staging (clutser) independently in vCenter before my vCenter license expires.

  Can anyone please explain or help me do this?

  Thanks in advance.

  Hi Carlos,

  Hope that you use the web client.

  Basically, the question is, you must remove a host in a cluster have DRS and HA.  To remove a HOST

  Put the HOST in maintenance mode - > check all VM's was able to move to another HOST, then right-click and disconnect, finally right click and delete.

  If you need to keep the virtual machine to the same physical host and you have properly configured a standard switch.

  Click with the right button on the cluster and DRS recommendation opt for manual. maintenance mode, then right click and then disconnect, finally just right-click and delete.

  hope this helps you.

• ESXi 5.1 status host HA is showing that the election

  Hello

  I have a node 4 ESXi 5.1 HA and DRS Cluster. Recently, I replaced all these hosts SSL certificates and prior to this activity, I had turned off the AP. Now, after replacing the hosts SSL certificates - when I am allowing the PA on the cluster, 1 single ESXi host is projection status of HA - ' Running (Master) and rest all three hosts are 'Election' HA status.»

  Tried to re - install the HA agent on the host, but issue still persists. Also tried the re - configure the AP on hosts ESXi, deactivation and activation of AP on the cluster, but no luck.

  Can someone help me for that to be resolved.

  Thank you

  KC

  Hi all

  Thanks for all your response.

  Problem is solved without the help of the HostReconnect.pl script. I followed the steps below and now all ESXi hosts demonstrate normal HA status.

  (1) put the host in Maintenance Mode. Unplug and remove from the vCenter server.

  (2) restart the management through DCUI Agent.

  (3) uninstalled the HA agent using the command line.

  (4) add the host to the Cluster.

  5) out of Maintenance Mode.

  By following these steps - correctly configured the AP on all four ESXi hosts. Now a single host is show as master and rest three hosts are displayed as slaves HA status.

  Kind regards

• Query - moving from ESX 4.0 (cluster) to ESXi 4.1 (cluster) license

  Hi all

  Am very new to VMware, please bear with me.

  We have in our existing Production cluster, consisting of three (3) 4.0 ESX servers and the intention is to replace them with ESXi 4.1 (U1) (under license).

  The plan should gradually slide each ESX 4.0 Server and install ESXi 4.1 (U1) of an image from HP directly on top.

  No drama it (?), but what about the licenses...

  I have a few questions I have to date not been able to acqurie myself.

  1. With each of the VH in the Production cluster, are we able to move a server in the cluster, upgrade to ESXi 4.1 and go back to the same cluster?
     
     
  2. If NO to question 1, which would be the recommended upgrade path where there is one (1) cluster, three VH (currently ESX 4.0) and we replace with ESXi 4.1 (U1).
     
     We have x 1 vCenter Server Foundation 4 license and three(x3) vShpere4 licenses advanced.
     
     Must these licenses be updated too?

  Am deparate to find answers to these questions.

  Kind regards

  Cameron

  HI - welcome to the community.

  The answer to your question is YES - you can re - allocate your ESX 4.0 license to your hosts updated. the license is generic and can be removed from a host and added to the other using the License Manager.
