• Upgrade of a single host with Shared Storage

  Getting ready to upgrade my ESX 3.5 hosts to vSphere.  I've already upgraded to vCenter.  I have two hosts managed by vSphere, and both hosts have a storage area of channel shared fiber that guests are on.  Each server can see all shared data stores.  I want to upgrade a single host first, then later upgrade the other host.  I've migrated the guests running to 2nd host whose I am not upgraded at the moment.

  My question is can I upgrade the first host using Update Manager?  What happens to guests in data warehouses that run on 2nd hosts?  Will they be affected?

  > My question is can I upgrade the first host using Update Manager?

  Yes.

  > What will happen to customers in data stores that run on 2nd hosts? Will they be affected?

  They will not be affected.

• Share resources between the 2 ESX 4.0 hosts without shared storage

  Hello guys,.

  I have the following question, I want to clarify.

  Imagine that we have 2 host ESX 4.0 with more functional license acquired (HA, VMotion, DRS, etc.)

  The two physical servers are identical. Don t have access to any kind of shared storage (San, no iSCSI, NAS no, etc.)

  In host #1 I installed all the virtual machines using local storage.

  Is it posible to use the host #2 resources (memory and CPU) to give more power to accommodate #1.

  My doubt is if it is posible to have a VM installed in local HD in home #1 and using RAM or / and CPU host # 2.

  Just do a cluster between the two hosts to empower the host #1 resources (not use DRS or functions of Vmotion)

  Let me know if I explained in a good way or not.

  Hope someone can clarify this for me.

  Thanks in advance

  It is not possible, even if you have the shared storage.

  There is no possibility that allows you access to CPU and memory of 2 resources different hosts.

  See you soon,.

• Upgrade and migration of 3.5.0upd0 to 4.0upd1 and shared storage iSCSI

  Hi people,

  I've got 2 ESX host: Alpha and beta. Two of them are connected to a cabin of iSCSI with some created shared storage drive (all VMFS3 v3.31). And both had ESX 3.5.0 update0

  I migrated all the VMS running in the Alpha host for shared storage and made host Beta to run (clones cold or simply reassign files). Then I bâtait Alpha from scratch and I installed vSphere 4.0 in it. I also created in its local storage space bit a new virtual machine with vCenter4 inside. It has worked well.

  Then I had to migrate Beta and its virtual machines, too. I first tried to manage the host with vCenter4, but it is not backward compatible.

  So I'll use the host update utility to upgrade beta I saw in a video tutorial, but my doubts are...

  • Option 1:

  Disable all virtual machines managed in host Beta.

  Configure the iSCSI client in Alpha, add storage shared cabin and try to manage the virtual machines already extinct. This reduces the time to downgrade.

  Upgrade Vmware Tools in the virtual machines (v4 to v7 type VM). Required reboots.

  Upgrade host Beta (with no SMV in there and unplug the cable of iSCSI) vSphere4.

  Connect and configure the iSCSI version beta customer.

  Manage the host with the new vCenter4 Beta.

  Configure the vMotion, DRS etc. in both hosts.

  • Option 2:

  Disable all virtual machines managed in host Beta.

  Upgrade host Beta (with no SMV in there and unplug the cable of iSCSI) vSphere4. Downgrade time increases.

  Connect and configure the iSCSI version beta customer.

  Upgrade Vmware Tools in the virtual machines (v4 to v7 type VM). Required reboots.

  Manage the host with the new vCenter4 Beta.

  Configure the vMotion, DRS etc. in both hosts.

  Which option is the best? Maybe is it possible to apply a third? What do you think?

  Thanks in advance.

  without loss of performance?

  Yes. VM with v4 works very well.

  The only problem is that you lose some new features, like the new drivers and FT.

  Note also that Standalone VMware Converter 4.x can also convert between v4 and v7 and vice versa.

• vMotion (without shared storage) between two hosts with different vSwitches standard s VM

  I can VM vMotion (without shared storage) between two hosts with different vSwitches standard? The vSwitches on these two hosts have different names and number of NIC, but have the same name of portgroup.

  
  Thank you.

  Yes, you can in a Storage VMotion to one Esxi to another with no shared storage...

  It is important the portgroup bears the same name... This is the reference for the VM...

• Move a virtual machine to turn off between two hosts, shared storage

  Dear Experts,

  Please guide me for the next case. There are two hosts of Esxi, host 1 is Esxi 4.0 and host 2 is Esxi 4.1. There are store data SAN storage that is visible to both hosts.

  I watched solard winds VM monitor utility that hosting 2 consumes 90% of the memory while its processor is ok. On host 1 is normal. So, I want to spend only a few VM of to host 1. So please correct me if what I think are OK. I will turn off the virtual machine to be moved from host 2. Then I it will remove host 2 inventory. Then on host 1, I'll go to the data store in the folder that VM and do a right click on the file 'say add to the inventory' and now I'm going to see this virtual machine in the inventory of the host list, just turn on and everything is perfect, is this correct?

  Second question on the same hosts, there are a few other data stores that are visible to a host. As if this is the case there is a virtual machine on a data store that is visible to host 2 and I want to spend this VM to host 1 to reduce load on host 2. How to move this virtual machine because this data store is not visible to host 1? Will I have to copy this VM files in a data store that is visible to host 1? If YES then what real required to copy files?

  Kindly help me.

  Kind regards

  From your description I m assuming that you use not vCenter to manage your hosts, correct?

  If you have a store of data shared between two hosts you can do the steps you descripte (power off, remove the inventory etc.).

  For your second case there are several ways, it depends on where you want to place the virtual machine in the future. Wouldn't be on the shared data store that already exists or can in the local data store on the other host? Or is there an option to also display the current data store to host 1?

  If you want to copy the VM files copy the whole folder of it.

  Kind regards

• Two servers vCenter and shared storage

  Hi all

  Is it possible to have two vCenter environment, vCenter 5.1 and 5.5 vCenter and each vcenter has two esxi hosts to vCenter 5.1 a 5.1 host esxi and vCenter 5.5 has esxi hosts.

  All four hosts to access the same shared storage (SAN).

  VCenter hosts different access to the shared storage will damage the virtual machines on storage?

  Thank you...

  Essentially access a data store from multiple hosts that are running different versions. However, in the case of these hosts are not managed by the same server vCenter Server, it is your responsibility to ensure that guests will not access the same VMs (records) system and maximum supported are not outdated storage vMotion tasks, for example simultaneous for a data store...

  Also don't forget that functions like the control of storage i/o may not work as expected.

• Dell VRTX + vCenter 5.5 + Shared storage is ESXi host import issue in vCenter. Help, please!

  All,

  I have two VRTX to be used for lab purposes that I am currently in configuration.

  Blades feature 4 VRTX with a shared storage infrastructure. Each blade has 5.5 installed on ESXi.

  I configured the shared on the VRTX storage, and all the blades can go very well.

  The question I'm currently facing is when you add the vCenter for managing ESXi hosts.

  Add the first host goes without a hitch. However, add any later host fail, because vCenter finds datastore attached hosts to have the same identifier.

  The error message is (see the attached screenshot): ' Datastore 'Main Shared-storage' is in conflict with a store of data that exists in the data center which has the same URL (ds: / / vmfs/volumes/xxxxx /), but is supported by different physical storage.

  Someone knows how to fix this?

  Thank you.

  Thanks for the reply.

  I think that I have found a workaround.

  First of all, this link does not address my particular issue.

  See, it's a whole new vCenter device installation and configuration. Only one of the four hosts to add host has been added.

  Still, the problem is that each ESXi host is a blade VRTX (M620), which has access to the data store created on the shared storage of VRTX.

  Basically, each host is editing the data store shared even (the only data store created on the shared storage), which works very well except for vCenter complain when you import the hosts.

  In any case, my resolution was as follows:

  -Add the first host with the attached and mounted data store

  -Remove the data store and detach the controller shared by other guests before adding in vCenter

  -Re-attach the controller shared and set up the data store via vCenter once guests have been added

  -Re-configure each host for vSphere HA if necessary

  Thank you.

• Migrate virtual machines from HP G7(single host) for HP G8 (Cluster) without shared storage

  Hello

  I have 2 esxi host (hp dl 380 G8) and put them in a cluster and other host esxi (dl 380 g7) and I have no shared storage and use local disks just now I must spend my VM G7 server a cluster of the G8 but I want to know I can join my cluster g8 g7 and migrate web vmware machines without any downtime?

  I want to know can migrate without downtime with localdisk? I have no shared storage

  Best regards

  BAbak

  can I join g7 to my cluster of the g8

  You can mix into clusters hosts all desired, even Intel and AMD at least that you enable EVC on the cluster (of course, HA or DRS require shared storage compatible/CPU). However, you need not to have even just cluster hosts to migrate virtual machines through vMotion between them.

  migrate web vmware machines without any downtime?

  Don't know what this "web vmware' but yes, because ESXi 5.1, you can use"enhanced vMotion"to live migrate virtual machines without service interruption from one host to another, even without shared storage:

  Migration with vMotion in environments without shared storage

  The usual vMotion requirements apply. Also you can only live migrate virtual machines from the old host to the new hosts because of different generations of CPU (and back as long as you don't have bike powered virtual machines on new hosts).

• Move the virtual machine from one host to another with shared storage

  Hello

  I have a question on how to move a virtual machine from one ESX 4 host to a host ESXi 5.  These hosts have access to the same shared storage but the ESX 4 host is outside the network and host ESXi 5 is inside the network so vMotion is not an option.  They are in different groups.  I know that there must be an easy way to move this virtual machine, but for the life of me, I can't find it.  I guess I have remove the virtual machine from the external cluster but how to make the virtual machine in the internal cluster?

  Thanks in advance...

  If both host access to the data store even where VM's store, just stop the virtual machine, remove inventory on ESXi 4, go to ESXi 5 vSphere vSphere, browse the data store where the VM is stored, do a right-click on the .vmx file and add to the inventory.

• How can I access a guest on a shared storage to another host?

  I want to better understand fail the course and the first thing I want to do is the following.

  I installed a guest disk storage fibre channel. I want to remove it from a host, and hosted it on another host.

  How can I go about it?

  Mike

  With your two hosts of ESXi, you will be able to access the same LUN.  On host 2, browse the data store, right-click on the VMX file and select Add to the inventory.  You can have virtual machine saved on both hosts, but the host that is running the virtual computer locks the files if you will not be able to accidentally start the virtual machine.

  You can also consider adding the vCenter server to manage your hosts together.  Until the end of April, you can get 3 licenses VC agent for US $500 and vCenter Foundation.

• Problem when adding 2nd host in Iscsi storage shared

  Hello people.

  I'll try to explain exactly my problem even if it is a little difficult liitle!

  First of all, we are talking about a test environment that is installed in my house just for learning purposes.

  I am facing a strange my iscsi storage behavior when trying to join a second host to storage vmotion purposes. I was using an Esx host (3.5) for a while and I had no problem with the iscsi storage (I use an old pc with freenas on it). I must say that I got lucky, also, local sata controllers have been recognized so I could test the Storage Vmotion between two storages (Commons and iscsi) with success in this host.

  To continue to learn, I decided to also buy another pc to test Ha cluster, Vmotion, DRS. Unfortunately, I couldn't find the same material and who as well as sata controllers do not to be recognized, so I used a disk ata for OS and my intention was to use for the volume vmfs3 iscsi storage.

  In the first host esx I used, you can see 3 storage adapters: vmhba32 vmhba33& gt; Controllers local sata,34vmhba& gt; initiator iscsi software

  In the second esx host, you can see only the vmhba32- & gt; the iSCSI Software initiator.

  The first time everything worked ok, which means that I have attached iscsi storage in host the2nd by rescaning the vmhba and I was able to browse the datstore and see the contents of it, but it lasted only 10 minutes. Then suddenly I lost the connection to common storage to both hosts, I could see in the section maps of storage, but when I pressed update in the storage section, nothing happened and even when I tried to add it using the add storage I received the message usual "cannot read the partition table information. After being a little more careful I noticed that in the section storage cards, I could see the same vmhba34 in the two hosts with the same alias to the host of the first, and here's the strangest part, the situation I described above has been changing from time to time, which means that a few times I have seen the vmhba32 in both hosts and after some time vmhba34 in both hosts! (crazy)

  I took the big decision after playing with the partition table, without effect to use the ' vmkfstool - C vmfs3 s ' _free "_ / vmfs/devices/disks/vmhba32: 0:0:1" command

  in the second host, of course, I lost all data, but now with a simple refresh in this host, I was able to see the storage.

  Unfortunately, I still couldn't ' 1 host storage access and I published the same command "vmkfstool - C vmfs3 s"free"" / vmfs/devices/disks/vmhba34: 0:0:1 ""

  with only the change you see in bold. Accordingly, it was to see the storage after a refresh with free (1) name.

  Now he is currently working for 2 days with this way not recommended and what I would be really grateful if could help me clarify what exactly is happening.

  My main problem is that I am in front of a very unstable environment that might as well have the same unexpected problem in the future and I can't reformat always storage and loss of all virtual machines

  I tried to describe the best I could to this strange situation!

  Thank you for your time and any help or advice would be most welcome!

  I was looking for a similar solution. Seems to be the only iSCSI host is possible on freeNas. See here: http://apps.sourceforge.net/phpbb/freenas/viewtopic.php?f=53&t=403&sid=f4881e6e25e752e6ee8c6b0eae5887d3

  The only solution for learning seems to be to install the server ESX or ESXi in a virtual machine and then use iSCSI. Vm Instructions to complete the installation here (you must all PDFs 6) http://knowledge.xtravirt.com/white-papers/esx-3x.html or you can replace the opnefiler by the SUN's VM iSCSI. http://www.sun.com/storage/disk_systems/unified_storage/resources.jsp , you must use the vmware converter to convert the SUN's virtual to be used in ESX machine found this in a forum... but can not find more URL. I have not tried myself but, looking for just because you want to get a similar setup.

• vCenter virtual appliance Installation on shared storage

  Hello

  I'll start testing virtualization soon, and for storage, I'll use a Synology NAS DS212j. My goal is to create a cluster with two servers ESXi, with the virtual machines stored on the NAS.

  My question is should I plug my nas iSCSI on my ESXi and then deploy the model to the OVA of the appliance virtual vcenter or deploy the eggs on the physical storage of one of my ESXi and then I try it moved to the shared storage?

  I'm not sure if my question is simple, but thank you for your answer!

  C. N.

  Happy, I can help you

  You must configure the iSCSI conifguration for each host, Yes.

  But the second and all other guests later then analyze the map iSCSI and see the VMFS data store that you created with the first host and set up automatically.

  You don't need to add each host in the cluster even if. You only do that when you want to use functions such as HA and DRS on the hosts within the cluster.

• VMotion for one HA cluster to another - no shared storage

  I was trying to vmotion that two hosts and clusters of data from a virtual computer store between HA (no shared storage). The web client gives me this warning and I'm curious to know what he is talking about:

  **

  If this is done, the virtual machine will lose vSphere HA protection. If you proceed with this operation and it completes successfully, vSphere HA not will try to restart the virtual machine after a subsequent failure. vSphere HA protection is restored when network partitions or disk accessibility problems are solved...

  **

  HA is working in two groups, in terms of network and the heartbeat data store. So what exactly this message tells me thank you!

  I get the same warning when turf migrate a virtual machine between two clusters and I select the source host unreachable destination data store. If I select a store different data that is shared by the two poles of competitiveness, no warning appears.

  This warning is probably up for the vMotion suppose it will stay within the same cluster and check if the source host and destination can access the same data store. As the store of data (and config agent HA) is not shared between your source and destination hosts residing in different groups, it seems that the vMotion compatibility check guess it's a store of local data or something like that.

  However, once migrated to the new cluster, FDM HA agents should choose the new VM place very well and protect it according to your settings in cluster HA, so nothing to worry about here.

• Explanation of Shared Storage [newbie]

  I am new to the storage and vSphere, but I did some reading and I worked my way through of vSphere well enough.

  However, I'm confused about something in the vsphere-esxi-vcenter-server-51-storage-guide.pdf.

  It is said

  Network storage devices are shared. Data warehouses on accessible network storage devices by multiple
  guests at the same time.

  I'm not sure understand it.  If I understand well, SAN storage, if one of my ESXi hosts is connected to a SAN (LUN?) device, it is identical to a disk that is attached to the host phycially, i.e. host a level block on this device/disk io control.  How that benefit then?  It would not cause corruption of data to have two hosts with access at ground level to block for a given device?

  For most of the file systems and operating systems, which would be true.  However, some file systems / cluster systems are equipped with this type of multiple access in mind and fight against the corruption of the type you think with clever use of interlocks, etc.

  VMFS and ESXi/vSphere is one of these combinations.  VMFS is designed as a clustered file system and can manage many hosts, access to a volume.
