• cluster of 4 nodes with ESX Server

  I'll put up a cluster in vmware with RDM environment. (LUN CF) with MSCS cluster.

  The document of MSCS Cluster of vmware

  ()http://www.vmware.com/pdf/vi3_301_201_mscs.pdf( )

  recommended to use 2 node cluster.

  My question is, can not create a cluster of 4 nodes via CF? or it is a best practice...

  Thank you

  Sylvie

  Hello

  SAM has always been officially supported only with only 2 knots. This is the max that will support the cluster in a box (CiB). However, I heard of 8-node MSCS in the whole of boxes (not the IPC). Official support still probably will not exist.

• ESX server with 2 different storage array?

  Hello.

  I currently have my ESX servers connected to storage DS4700 and most berries.  Each ESX is double path via a switch which, in turn, allows me to see my DS4700.  My question is, can I i the area my ESX Server so that it can "see" my DS8300 and I would be able to assign LUNS of my ESX servers with no problems?  Both can coexist?  I think I should use for my DS4700 host bus adapters and host bus adapters that are dedicated to my DS8300?  A UNIX point, these 2 storage arrays do not 'communicate' the same way (for example, SDD and RDAC).

  Thank you.

  Steph

  SDD driver is for the multipath. VMware has its own multi-channel driver that is shipped with ESX server, you won't not any 3rd party multipathing software.

  In any case to be abel to see camps Bay you have no need to activate the software multpathing. It is intended only to provide a redundant path to any logical unit number hosted by a single table through several MS SPs/Ports.

  Area just for DS8300 ESX Server and a new analysis should see the new targets and when you present LUNS to your host definetion analyze again another you should see the DS8300 LUN.

  I hope this helps.

• Cannot use RDP with Windows server 2008

  Original title: a user cannot RDP

  Hello

  I have a windows 2008 R2 server with 5 licenses of Terminal Server. I set it up so that users can RDP to the server using RDP and access other machines via VNC, it's not connetced to a domain or whatever it is.
  All users can connect using any OS - Win XP, Win 7, but a user cannot get to their place of work - I can connect from home, of Germany, etc. using the same user name and password, but they can get on the server but their access is denied.
  They can telnet to the IP address but can't.

• Command updating ESX Server 3i, 3.5.0 build #207095

  I have a server ESX 3i, 3.5.0 build from 207095 and I'm trying to update with the latest patch (ESXe350-201302401-O - SG.zip) which I copied to a folder on the local drive:

  "/ vmfs/volumes/OS-Datastore/Patches / '.

  I run the commands:

  «esxupdate install /vmfs/volumes/OS-Datastore/Patches/ESXe350-201302401-O-SG.zip b»

  ... as well as

  "esxupdate install /vmfs/volumes/OS-Datastore/Patches/ESXe350-201302401-O-SG.zip d.

  ... and it is for me to give a new prompt. That means that means and why I can't update my installation?

  I also extracted the original zip file and created these sub zip files:

  "ESXe350-201302401-I - SG.zip".

  "ESXe350-201302401-T - BG.zip" and

  "ESXe350-201302401-C - SG.zip.

  ... I tried the command on them as anything does not.

  How can I get this patch inistalled?

  What is the right syntax?

  Thanks P.A.!

  VMware KB: Image of ESXi Server 3.5 June 2011 Rollup CD

  I missed an update and for this reason I have to do a clean install as shown in the link above.

  My version can't do any update or update more!

  What you need to know about the key Secure Update *.

  (

  ESXi Server 3.5 June 2011 Rollup CD image (2000593)

  This Installable CD contains ESX Secure Key Update ESXe350-201012401-I-BG.

  For more information about this fix, see Critical Impact: VMware ESXi 3.5, Patch ESXe350-201012401-I-BG: apply this hotfix to continue to apply patches on the ESXi 3.5 hosts after June 2011 (1030002).

  NOTE: If you have not applied this patch by June 1, 2011, you will not be able to then apply patches. To get your updated hosts up-to-date with ESX Server 3i 3.5 version is to apply this Installable CD as new installation. You can also switch to ESXi 4.0 Update 1 Installable.

  Thanks for your suggestions... at least it has led me to the answer.

• LUN and ESX Server - basic knowledge

  Hello...

  I'm trying to clarify the relationship of this LUN game in the Infrastructure of VI:

  (1) is it true that you can have 1 VMFS volume associated with ESX Server at a given time?   Or can we have multiple VMFS volumes running on all different LUN associated with the same ESX Server?

  (2) I know that you have have 'shared storage' between the ESX servers in a cluster of vmotion, but the fact that "the shared storage" refers to

  (a) the same VMFS volume (no matter how much LUN spans the VMFS volume) or

  (b) or can it be multiple different VMFS volumes (b/c multiple VMFS volumes can be associated to an ESX Server at a given time)

  (3) If you can have multiple VMFS volumes related to 1 ESX Server, make the virtual machine in a cluster of vmotion, they all live in the same VMFS volume?

  Thank you!

  Also remember that a VMFS data store cannot be greater than 2 TB.

  Also consider what would happen if an administrator has accidentally deleted a LUN

  VMware also creates SCSI reservations on a LUN basis whenever it creates a new virtual machine among other tasks. If these become too high, the logic unit number is locked significantly reducing the performance of the disk. Separation between the LUN, will help

• ESX Server 3.5 - strange time problems

  Hello world

  What is the final location, installing a new server ESX will pull its time to go?  It seems complete weird for me!  I just reinstalled the server that I use for testing because the clocks on my hosts are out of sync with ESX server 3 hours.  I know this only because whenever I restarted the clocks would become out of sync even once, I would manually fix them but if I restarted, then they would be out of sync again on restart.

  So I decided to start all over again and reinstalled.  I also noticed that the time on the BIOS was out of sync by 3 hours, so I fixed that, then during the installation, I used the GUI and ensured to this that all settings are correct.  I started and submitted my top vmdk files. Add a server to the inventory and ba-boom, it's always an hour out of sync!  If I put it to an internet time server synchronization in windows, it corrects itself, but is incorrect once again after a reboot.

  If I use VMWARE tools to synchronize with the host computer then the time is an hour off the coast.

  Please keep in mind, I'm a windows guy, this great process of setting the time using putty is a little hard to swallow.  Is there not an easier way to simply see what time the host uses and correct?

  Thank you.

  First when you install it gets it from the BIOS. Then when you have done this, you will want to configure NTP on the HOST. This by going to the tab "configuration" and then "time Setup". You can use the following internet time servers (just put you company firewall or something else allowing of course) 0.pool.ntp.org 1.pool.ntp.org 2.pool.ntp.org. The implementation is very easy and it will make sense to you that you do. Also, it will make ESX for NTP firewall when you submit.

  So you want if sure is installed on your windows guests and the value of the box sync with the machine virtual host of the vm tool. Important, disable the windows time service.

  Do this and your windows host will keep time properly.

• ESX Server guests and Local USB devices

  Is this possible with ESX Server 3.5 to connect to a guest operating system and load a USB device as a card reader connected to your laptop remotely?  How if possible?

  Is there a device that can be installed for the smart card reader, biometric readears, etc.. ??

  To summarize how ESX allows a remote user to plug in a usb device locally and have ESX assign to the team desired vmware instance?

  Thank you and sorry to be so green!

  Green is in fashion now Kyle - get with the program!

  MNANCE152 - doesn't this sound viable, or do you think you will have to take another route?  I'd be interested to hear what you come in the end, if you don't mind me posting it here.

  Good luck!

• Hot migration is possible with VMWare ESXi 5.1.0 without an ESX server management

  Hot migration is possible with VMWare ESXi 5.1.0 without an ESX server management?
  I wonder for a future issue, a scenario where a system administrator must build a Win2008 + DC on local storage, server
  then, once the physical box is integrated into the class network, the physical box is connected to the classified SAN storage.
  Is it possible to hot - migrate the server Win2008 + CC local storage to SAN storage at this time, with only the
  free version of VMWare ESXi 5.1.0?

  Welcome to the community - I guess that you are looking to do this, while the virtual machine is currently running - this is not possible without a management server, also called vCenetr, but all is not lost because you would be able spend the VM local storage to the San with the VM posered using the client storage management features

• ESX Server with a control VM, instead of the workstation

  Considering change of ESX Server to increase the memory available to my VM that is connected to the internet.  But I've been advised what ESX a second pc needs to combat it.  So it's no good in replacement of the workstation or player.

  Why can't a virtual machine with the guest only network use the computer controlling in ESX, playing the role of external control computer?

  If it is declared with a raw disk, it can even have full access on the host drive. You can then install vmware workstation virtual machine to edit .vmx via the user interface files, generate new hard or copy - pasting entire VM.

  And when you have need of more memory, you suspend this VM control and almost all memory is available for the computer connected to the internet virtual.

  Why not?

  ESX is a pretty primitive operating system - it can even display a beautiful picture because it has only a text console.

  Because it is so limited and restricted compared with other operating systems, it's so good to run virtual machines without GUI.

  The disadvantage of this design is that you need a second machine to display a virtual computer desk

• Add ESX server assessment to VC with error: there is not enough license installed to run the operation.

  Hi all:

  I added two esx servers in my vc received the error: there is not enough licnese installed to run the operation.

  There are some servers esx with correct license file in VI3.5U3 in my environment. I want to add more than two servers esx with evaluation mode in this virtual Center. I got error.

  connection to the esx server directly without vc, to feature license tab, I selected evaluation mode is ok. but I can't added these in vc. Why?

  can someone help out me.

  Thank you very much.

  hihiy

  I don't think you can, you need to turn your TC to eval too, and before we do, your VC should not exceeded calclation eval of 60 days from the first day, it has been installed.

  BTW, since you have valid VC 2.5 license, and is not the Foundation of VC, why don't you showing your ESX with eval license server to license? Add then the two ESX to your existing VC?

• Compatibility of VMware vCenter Server 4 Foundation to vSphere with ESX 3 Standard VI

  We are already use VMware ESX Server 3.5 VI.

  Our intention is to buy VMware vCenter Server 4 Foundation for vSphere addition VI ESX 3.5 Server running on a separate server. Our concern is;

  1. is VMware vCenter Server 4 Foundation for backward compatible product vSphere with VMware ESX Server 3.5?

  2 If no, then is it a similar product of VMware, which is compatible with VMware ESX Server 3.5?

  Please notify.

  VMware vCenter Server Foundation 4.0 can handle up to 3 vSphere or legacy hosts.  If you need to manage more than 3 guests, you should definitely consider vCenter Server Standard edition.

• ESX iptables, causing problems with the Server 3.5

  Hello

  ESX server is restarted.

  It is quite a large number of iptables rules prevents our monitoring system to check the memory disk, traffic, etc...

  I tried to delete all using iptables - F, but the system crashed and I had to connect through the ILO to reboot the system.

  is there a way to disable / remove all rules in iptables on an esx Server? We have other firewall in our infrastructure, we do not really need iptables or firewall installed with esx.

  Otherwise, what is the method for open access to a port or request so that we can temporary open the necessary port for our monitoring system?

  Thanks in advance

  Mario

  After excuting

  esxcfg-firewall - allowIncoming

  esxcfg-firewall - allowOutgoing

  You should get the following when you run iptables-L

  INPUT string (policy ACCEPT)

  target prot opt source destination

  Chain forward (policy DROP)

  target prot opt source destination

  Chain OUTPUT (policy ACCEPT)

  target prot opt source destination

  The esxcg-firewall command changes the rules in iptables on the ESX server host. I used iptables f to rinse the rulesets in the past (this change can not resist reboot as the configuration files are not changed), but it is recommended that any firewall adjustments using esxcfg-firewall.

  Try the firewall chkconfig--level 3

  diasable firewall after erasing rules.

  To activate just firewall chkconfig--level 3 on , then Start firewall service

  esxcfg-firewall - blockIncoming

  esxcfg-firewall - blockOutgoing
