Physically move the ESX servers

• Strange when network problem the ESX servers powered

  Hello.

  First of all, do not know if this is the right forum but I hope you can help.

  I have a question where to chance the firewall stops responding during a small number or a host/pcs/physical server randomly on my network. This problem started since the launch of VMware and two ESX servers. I think that its a problem ARP as erasing the NIC ARP cache on the windows computer that has trouble to the solve the problem temporarily. A permeant fix is to cut the ESX servers, which is obviously not a solution.

  Ive changed the firewall's Pack but have the same problem. Any thoughts on what to check on ESX to see what is the cause? My ESX servers currently have a unique NETWORK card on the LAN vSwitch for simplicity and a distinct vSwitch for 10 gb iSCSI, which is directly connected to the San. Very simple.

  Thank you

  Ive found my problem.

  My SAN, a HP MSA2040 manages a network of 192.168.200.x for internal use according to HP support. Even if id changed IP address of management to another network that it stills works this range. Therefore, the map was updated to the ARP tables and sending request to the bad MAC/IP who just happened to be the IP address of my gateway to some network hosts. Crazy stuff.

• Update Manager: it updates Virtual Center or just the ESX servers?

  Hi all.  After months of inactive Update Manager, I finally got it going again and so I need to install approximately 6 months of updates on my ESX servers.  This is the easy bit.  But how can I update my virtual server to the center of update 1-2.5 2.5 update 4?   Update Manager at level Virtual Center for you or is it a manual process?  That is to say.  Do I need to download the ISO and do an inplace upgrade?   Thanks in advance for any help

  see you soon

  The process of upgrading to vCenter is separated from the Update Manager. Download vCenter media - save your vCenter database and then run the installation program - it will do an upgrade on the spot.

  Here is a link to the upgrade guide - http://www.vmware.com/pdf/vi3_35/esx_3/r35u2/vi3_35_25_u2_upgrade_guide.pdf

• Move the ESX host again VC, VM permissions is needed

  @all:

  I have a big problem with the permissions on the virtual machine.

  Due to the fact that I created a new VC, I want to spend the ESX host for the new Victoria Cross. No problem, but it the individual permissions for VM to disappear.

  Well, I'm looking for a script powershell read/grouping, the name of the virtual machine and the permission is assigned (like the tab authorization VC). After the removal of the host, I would like to add the permissions to the virtual machine.

  Probably something with "AuthorizationManager" but I can't make it work...

  Any help is appreciated

  THX

  If you want to only read permissions for virtual machines in a specific data center do you it like this

  $serviceInstance = get-view ServiceInstance
  $authMgr = get-view $serviceInstance.Content.authorizationManager
  $report =@()
  
  # Read and list all permissions for VMs in Datacenter
  Get-Datacenter  | Get-VM | %{
    $entity = $_ | Get-View
    $permissions = $authMgr.RetrieveEntityPermissions($entity.MoRef, $false)
    foreach($perm in $permissions){
      $row = "" | Select VMname, Principal, Role, Group
       $row.VMname = $entity.Name
       $row.Principal = $perm.Principal
       foreach($role in $authMgr.RoleList){
         if($perm.RoleId -eq $role.RoleId){
          $row.Role = $role.Info.Label
            break
         }
       }
       $row.Group = $perm.Group
      $report += $row
    }
  }

• Changed my subnet for ESX farm.  I also changed the esx servers 'anaconda' cfg file accordingly... keeps still old IP to the reboot?

  Hello world

  I changed my subnet and everythign works fine in my esx vcserver settings until I reboot... The ESX Server restores the OLD IP address.  I run ifconfig and it changes again, but why he returns to the reboots?  I have no idea what the anaconda file does but it seems to be some startup parameters, so I thought that I took care of the question... other ideas?  Thanks again for your help!

  The ifconfig command will not change permanently to the IP address associated with an interface.

  To do the following in the console

  Edit/etc/syscongfig/network (if necessary change Gateway value)

  Edit/etc/sysconfig/network-scripts/ifcfg-vswif0 (change IP, network and the mask)

  Check/etc/hosts and /etc/resolv.conf (for all changes to the network settings that may be necessary)

  Type "service network restart" (without the quotes)

  The system maintained the new IP address? If so, reboot and ensure that it retains the new IP address.

  You will need to reconnect the VC system.

  Anaconda is used by the process of kickstart RHEL (used for the initial version of ESX host) I know you can monkey with the configs but I tend to do things the old-fashioned way.

• MAC addresses of our network interface cards physical on the ESX host

  I asked a very interesting question.   What is the MAC address for each physical network cards within our ESX host.   Our host ESX3.5Update4 has 6 of them.

  I am able to ESXCfg allows to identify the vNIC but assimilates to the physical network adapters?   or, how can I find the MAC address of the physical network adapters?

  No, I mean there are additional MAC addresses that the switch can 'see '.  The service console interface have a MAC, and address that will be displayed if you run 'ifconfig', but vmkernel will not be displayed in this way, use "esxcfg-vmknic - l" to display this MAC address.  The virtual machine each have their own of the MAC you can get that from their configuration files, or the vi client.

• Move the physical disk to another server ESXi

  Hey guys,.

  I copied a virtual computer to another physical disk on my ESXi server.

  Is it possible to take the disk and move it physically

  Another ESXi machine and see the data existing on the second ESXi store

  Server?

  We were doing the initial test on a test machine. Now I want to move the virtual machine to a server better

  with a raid array. I know that I can use

  SCP, but I prefer not bogged down my network file copy 100 gig.

  When I physically move the disc I can see on the second

  machine. But I don't know how to add it in

  storage. When I use the wizard, I get a

  WARNING: it will wipe the data.

  Thank you

  Should be possible, but you may need to activate volume resignaturing on ESXi in so he could see the new drive.  Search the VMware KB for "will esx" and you should be able to find an article that explains how to...

• Move the disks from 4.0 to 4.1 Server

  Hello all-

  I was wondering what to expect with my migration to a new server esxi 4.1. I am running esxi 4.0 with two disks of data with all my s vm in data warehouses. The 4.1 server is built and ready to go, can I just physically move the disks to the new server and it will recognize that they are already setup with data on board or he'll want to reformat the discs when he sees them? I hope that it leaves everything intact and I can just reattach the existing virtual machine. I have all the vm saved in any case to another location on the drive just in case.

  Thanks for any idea that you can provide.

  John

  It should work exactly as you described.

  After setting the record, ESXi should be viewed as VMFS in "Configuration" data warehouses--> "of storage. All you have to do is to add virtual machines to inventory, by right clicking on the vmx files.

  André

  EDIT: I guess that you have single disks. If you have a RAID configuration, ESX hosts must see logical volumes after reboot.

• Check the ESX path to correct the SAN enclosure

  I don't know if this is the right forum...

  I have a HP Blade enclosure connected to a HP EVA 6 K and EVA 3 K SAN. All blades that I currently have in the enclosure point to my 6K SAN controllers are active/active. 2 new servers blade I've built will be used to condense some old physical servers that are connected to the EVA 3 K that has active/passive controllers.

  For the new 2 knives I built I want to make sure that their way is properly connected to the 3 K ONLY. Is there a way to check the correct path to the 3 K before starting to move the vm servers on?

  With the current game I have, when I added a new blade I add it to the pool side san for the 6 K and then unmask and LUN I want to see. These 2 blades which will see the 3K are the first in the pen to point only to the 3K.

• How to move the VM to another storage without Virtual Center

  Hello-

  I read some other posts on the moving a virtual computer to another storage without Virtual Center and there is a good post, but I have different problems, because my situation is a little different.

  My VC is currently stored on a local storage of the ESX servers.  It is the virtual machine that I want to move to a shared storage.

  You guys can help me with some of the steps I can take to move this shared storage better?

  I'm not too familiar with Linux, so even copy files etc, I'm not sure how to do it.

• move the app to the sd card

• Move the database on the DSO from one server to the other in AIX

  Hello

  We have a project to move a Database (11.2.0.2) in ASM (stand-alone IM 11.2.0.4) in AIX. I followed the steps, but it failed.

  1. on the source server, I stop the database and removed the data DISKGROUP. I also took the diskgroup backup metadata before going down it.

  2 storage team has removed the mapping of the discs and they remapped to the new server. However, the names of disks have changed
  Note: There is no oracleasm and the drive string used is/dev/rhdisk *. The number of disk changed in the new server. However, we have renamed these discs.

  3 installed GI in silent mode with the "software only" option and then set up AP using roothas.pl.

  4. install Oracle database on the same level of patch from the source.

  5 ASM set up using a small new disc using ASMCA in silent mode.

  6. after the configuration of ASM, I don't see the Diskgroup database, but I see the drives as CANDIDATE disks.

  7. now, I restored the metadata from backup I took in the first step.

  8 Diskgroup appears and mounted. However, there is no data. All the data disappeared.

  Please can anyone suggest what I missed? Support for Oracle is not clear in its instructions.

  It's test database, so we could afford to lose the data. We cannot follow duplicate RMAN that our Production database is very large, and all backups are in bands. We also long downtime. Therefore, the only option we have is to physically move the LUNS.

  In my opinion, ASM has not read the header information of disk that LUNS are mapped before ASM is configured and consider them as CANDIDATE disks. Please specify.

  Thank you

  Vikas

  ASM devices that belong to a disk group contain the header special ASM data, that ASM uses to identify the disks. The path of unity or the name of the device as such is irrelevant. ASM must know the chain drive in order to locate the devices. I do not know what has been mapped or put in correspondence, but if the disks appear as candidate ASM disks, then information should have been erased in the process.

  Why not simply create a full database backup using RMAN and then restore and recover the database on the new server? Provided that the new server has the same software and ASM starts, this should be easy.

• How to control vmotion license to the ESX Server

  I have 5 servers ESX 3.5 U3 in my vCenter.  Two are using host license and three are in a cluster and using the server license assigned by my license server, that runs on vCenter.  However, my ESX servers two stand alone using the host license receive a license of vmotion by my license server and my ESX servers in my cluster but cannot get a license of vmotion because their attributed to the wrong ESX Server.

  How can I get the vmotion license released by the ESX servers who don't need and make it available on my ESX Server who need?  My three ESX servers in cluster shared storage for vmotion and don't have my two stand alone ESX servers.

  I tried simple things, like the disconnection of servers and ESX servers in reconnection vCenter, re-reading of license files, restart the license server, etc..  license and vCenter server is 2.5 U4.

  Thanks in advance.  Jim

  go to the configuration tab and click Networking, you have a Port VMkernel configuration?  If so, edit click the vSwitch properties, change your VMkernel port settings and uncheck the box that says VMotion: enabled.

• VMDK file unreadable after migration of VM & update of the ESX Server

  Last night we have updated the ESX servers here and in the migration process machines from one node to the other (by placing a single node of the cluster in maintenance mode). During this migration, the VMs one has stopped running. When we finished the migration and had updated the ESX Server, we brought the system to the top and tried to start this virtual machine.

  First, we looked in the directory of the virtual machine and saw that the VMDK file has a different name, with - dish at the end (before hard). We have renamed the file, removing the - flat extension, and this is where we saw these messages. ESX Server always gbehaved as if the file did not exist or was unreadable. Here is an extract from the log:

  The VMDK file is indeed the most, but VMware seems unable to open it. For what it's worth, it was also noted a .hlog file in the directory of the virtual machine on the server:

  Anyone can shed some light on this? Done-flat suffix in the VMDK file have a special meaning? Any recommendations for the rescue of this virtual machine?

  Thank you very much in advance.

• Best practices for controlling Remote Sites ESX servers

  Hi all

  I was wondering what the best practices or the options are for the management of the ESX servers in remote offices or branch.  I know that you can always use the VI to control on the site server, but what happens if you want to use some of the functions of the virtual Center?  How remotely manage and leverage capacity of Virutal Center in remote sites or branch offices, since you can't have Virutal Center installed in a domain.

  Other then a VPN dedicated to all remote offices or a branch is there another way to use Virtual Center to remotely manage the ESX servers in remote offices or branch?

  What are your current plans DR if the main site is going to host VC?

  You can run your VC in a VM and have power clone on a remote site or both incase of total failure.

  Then with the help of RCL etc. under the texiwill recommend and/or vMotion VM VC to other sites if necessary.
