• 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.

• OBIEE Disaster Recovery can be configured without CARS and shared storage?

  Hi people,

  As say the topic, I'm looking for advice on disaster recovery. What I find in the docs pointing me to the high availability configuration, or maybe I'm simply not find the docs I'm looking for. And it always points to the RAC, etc. of shared storage. My database is already configured to Dataguard and I want to do things this way, with a recovery site which isn't always upwards and a part of a cluster (although it's very well as long as the CAR is not involved), I'm looking for some feedback on how people do things. I have 11.1 now, but will be upgrading to 12.2 soon.  Just a straight stitch to the documentation would be useful if I'm missing just that.

  Thank you

  -Adam

  Since you have already configured Dataguard and in a DR situation, you will be switching/switch on your course in standby mode and it will active db. All this is fine. You can do the same with instances of weblogic OBIEE. You can clone your binaries installed using tools provided by Oracle cloning, or build binaries from weblogic with the accurate determination of drive on your Dr. use the pack of weblogic server and then unzip tool to archive your entire weblogic domain and it Unarchive in your prepared DR server.

  Now, you have to just challenge the hostname (s) of your domain to point to your database JDBC data sources and weblogic.

  To facilitate the task, you can change the host name used by weblogic to host alias that can be remapped in DNS during DR. Similarly, you can change the JDBC connection string so that it can automatically select the active database as long as you use a database instead of a SID service name in the connection string.

  You will need to regularly make a pack on your weblogic domain in order to maintain an up-to-date backup of your domain proximity. Similarly, if you have reports that are stored on the file system, they must also be backed up regularly so that they can be restored.

• 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.

• vSphere high availability with no shared storage? And general problems with VMware partner supplier

  
  HA can function without shared storage?

  It may not by the availability of vSphere manual.  However the global VMware partner who sold me on VMware solution said that the shared storage is not required for HA.

  This is the same guy who told me that I would not need to buy Windows Server licenses because everything was included in the package (vSphere Essentials Plus).  Now, I have no Windows license, no shared storage and a customer who will not be happy that we did not include these costs in the citation for this project.

  HA can function without shared storage?

  No.... you need a storage shared for HA.

  This is the same guy who told me that I would not need to buy Windows Server licenses because everything was included in the package (vSphere Essentials Plus).  Now, I have no Windows license, no shared storage and a customer who will not be happy that we did not include these costs in the citation for this project.

  Maybe your partner speak the vCenter Server Appliance that is included on vSphere Essentials Plus and you can use this device to manage your vSphere, ESXi without need a VM of Windows (with Windows license) to install the vCenter server.

• Nested ESXi 5.1 and iSCSI Shared Storage

  People:

  I am unable to get my ESXi servers nested to see the iSCSI shared storage, that I put in place for them.  I use iSCSI for the ESXi host, who holds the guests of ESXi, so I have a successful iSCSI configuration to use as my reference.

  Here's what I have for the host network config:

  iSCSI targets

  + IP1: 172.16.16.7 (subnet for host IP storage)

  + IP2: 172.16.17.7 (subnet for storage over IP comments)

  vSwitch associated vmnic2 on NIC IP storage

  + Port "IP storage" group containing virtual NIC both ESXi hosts

  + VMkernel Port for iSCSI host connections: 172.16.16.28

  Here's what I have to config network comments:

  + The highest virtual NIC group of ports "IP storage".

  + vSwitch with only a VMkernel port for iSCSI of the guest connections: 172.16.17.38

  From the iSCSI host, I am able to ping 172.16.16.28.  However, I am unable to ping 172.16.17.38, and here's the really confusing part - I am able to get an answer ARP of that associated with the VMkernel port with the correct MAC network CARD!  This eliminates all kinds of potential configuration issues (for example means bad NIC, bad IP, etc..)

  The firewall on the host indicates the software iSCSI port outgoing 3260 Client is open.  Capture of the target iSCSI host package reveals no. TRAFFIC from VMkernel IP guest when updating to storage adapters.

  What should I look at?  The configuration of the host against the host looks identical yet we work and there is no...

  -Steve

  In the debugging process so, I turned on the "Promiscuous" mode on the vSwitch associated vmnic2 on the NETWORK card on the host IP storage ESXi and poof!  Everything magically started working.  The iSCSI traffic be unicast, so I don't see why promiscuous mode would be necessary, but I can't argue with the results observed.  Clearly, I have more to learn more about nested ESX, that's why I'm playing with it.  :-)

• vMotion and Shared vs Local storage

  Greetings to all

  It does not say much on the local storage in my book by Lowe.

  In fact its as if no one is using to vSphere5 without an external storage array any.

  It indicates that 'the shared storage' is required for vMotion.

  But I when I talked to a vMWare engineer said he local storage will work as a shared storage.

  Kind of confused here. I saw that this mentioned anywhere.

  We have two new servers Dell with ESXi5.

  They have discs SAS6 6 x 300 G each. It's our storage.

  We want the ability to run vMotion between these two servers.

  Can it be configured to be a storage shared in vCenter Server or when you add a virtual machine?

  Thanks in advance.

  Yes, there is an extra charge - this doc prepares aid http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2002309

• 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).

• vSphere 6 FT cannot yet compensate for shared storage takedown?

  Hello

  a few questions about the PI with vsphere 6.0 — we just noted this in the test lab:

  (a) is it true that the 'source' vm where you want to enable IP MUST be on shared storage? because it seems that way.

  As you mentioned in the documents, it is now possible to locate the storage for the target on a separate storage VMDK (this can also be a non-shared storage just seen by the target host).

  Now the second question: we ft´t just a machine (source on the shared storage, target on a local storage of target esxi. Bootet, installed the virtual machine just cool. Each host may die - all cool.

  NOW, we killed the shared storage of laboratory. We wondered: Hmmmm... OK... If the second host the vmdk and both hosts have the namespace and the vmx why not keep the virtual machine running on the target storage? But what we saw was disappointing: the protected virtual machine became unresponsive. Is this expected behavior? The new ft cannot lose the shared storage?

  Best regards

  Joerg

  Unfortunately, FT in vSphere 6 still relies on storage shared for the tiebreaker file and source VMX file and other functions.

• vLAN: vm - vMotion - Shared Storage

  Hello. I set up a test lab, set up as follows:

  ESX01 (ESXi v5) - HP-DL380-G5 (Dual GB NIC)

  ESX02 (ESXi v5) - HP-DL380-G5 (Dual GB NIC)

  I have installed OpenFiler on a third G5 and have configured the shared storage iSCSI. This hangs together on a layer 3 switch extremes (10/100 but vMotion always works well).

  I would like to create virtual networks to improve my knowledge in this area. I know how to create them at the level of the switch, tag etc but I'm not familiar with the concept of full use in VMware. I am also limited by the number of NIC on the host computers.

  In my production environment (set up by third party), each host has 4 NETWORK cards. Two vSwitches are configured as follows:

  vSwitch0

  vmnic1

  vmnic0

  VMkernel Port

  vMotion

  vmk1 (ip x.x.x.x. VLAN ID 100)

  VMkernel Port

  Management

  vmk0 (ip x.x.x.x. VLAN ID 200)

  vSwitch1

  Virtual Machine port group

  Production

  All virtual machines use its option

  Any advice on configuring vSwitches + addition of virtual networks within my appreciated Limited NIC Test Laboratory.

  Phil.

  You can duplicate your production environment with two virtual switches on each host and simply connect each vSwitch with a NIC physical you will have no redundancy, but this may be acceptable, since it is a laboratory.

  If you want redundancy you will need to create a unique vSwitch, with two connected physical network cards. You create all your interfaces VMK and groups of comments on this switch ports and allow all the VLANS on the two trunks to the extreme switch.

  In order to separate your traffic MGMT and VMotion of your comments traffic, you will need to go into the properties for each VMK or port group and select the option "overide switch failover order". I had put the active Vmotion on physical NIC1 and NIC2 watch. I put all other active traffic on Eve on NIC1 and NIC2.

• shared storage

  Hi everyone, iam configuration lab and I need shared storage

  I want to know if I can share a Director on one of my servers esxi and use it as a shared storage

  How to make a server esxi storage shared among other esxi servers

  You mean like we use openfile on a windows or linux box to provied storage lun with free space on them, like that on ESXi.

  TAT is then not possible. But still, you can create a virtual machine set up all the storage, installing openfile or starwind, from there, you can give access to shared another esxi storage.

  or

  Installing vcenter

  create the cluster

  every 2 or 3 esxi, who owns the local data store.

  now install vmware storage appliance - through you can make use of all the local data store to be shared across all the esxi.

• VMware, GFS2 and Red Hat Cluster Suite

  Hello
  
  I want to implement Red Hat Cluster Suite with a shared file system GFS2 on hosts VMware running RHEL 5.7. I want the implementation to be fully supported by Red Hat and VMware.
  
  This Red Hat https://access.redhat.com/kb/docs/DOC-46375 document says that VMDK is not supported, but that RDM (in virtual or physical Compatibility Mode Compatibility Mode) are fully supported when the perimeter fence fence_vmware_soap is used.
  
  That's why I intend to place GFS2 filesystem on one of the two types of disc RDM (and obviously have the Red Hat operating system on another drive). I'm a bit confused about the options well! My questions are:
  
  (1) the ROW should be added to an additional SCSI controller on the guest, or can it be on the same controller as local drive (OS)? for example I just have a SCSI controller for the guest, with both OS and GFS2 storage?
  
  (2) how is the option 'Compatibility Mode' RDM (virtual or physical) affected by the option of 'sharing of SCSI Bus"of the SCSI controller (no, virtual or physical)? It's just different ways of putting the same thing? If so, which one is priority?
  
  (3) is it possible to vMotion these prompts do not turn off?
  
  Thanks a lot in anticipation, the experts!

  No RDM do not need to be on their virtual SCSI controller

  The RDM compatibility mode is chosen based on the cluster that you are proposing to run - if you plan to have have the cluster extend to ESXi hosts that you can select the physical compatibility. Similarly the shared SCSI Bus is also selected according to the configuration of cluster - physical if you plan to have a "cluster - everywhere-boxing ' or virtual, if you plan a"cluster-in-a-box"."

  (3) is it possible to vMotion these prompts do not turn off?

  No you are not able to vMotion a virtual machine that is part of a Cluster of BONES.

• move VMs from the local shared storage

  We are running ESXi 4.1 with local storage that we did experiments with VMware. Close have 2 new purchased hosts with a SAN for the shared storage, hopefully, they will arrive at the end of January. I need to build a couple of virtual machines to take care of a few issues until our new VM environment is set up. If I create a new virtual machine on my host with local storage and that you want to move to new hosts and the shared storage the arrival of our new purchase, I guess I can do it with vMotion? Other methods too? Also, is there anything I need to worry as move us VMS local shared storage storage and a new host of ramifications?

  Thanks for helping a newbie, Tom

  You will need Enterprise or Enterprise Plus access to Storage vMotion. vMotion moves a virtual machine from one host to the host running but no storage.

• Free/busy options high, with no shared storage

  Here is a little history on our Setup. CurrentY we run vmware server 2.0 on centos 5.4 on both servers in a data center to remove. Currently, what we are doing is a manual process to a level of poormans HA. We create a snapshot of the virtual machine (sometimes) and you use rsync to synchronize the virtual machine on the other server. Each server has 2 mirrored disks and disk 1 not mirrored. If each server synchronizes the reader not mirrored.

  I have a key for the company left, I wonder what would be my options for maximum availability with the two servers and HA. We would like to have the opportunity to have HA and FT, but the shared storage is not an option right now.

  Thank you!

  All VMware high availability options require a shred storage.

  You can create virtual shared storage on warehouses of local data (updated mirror network) with the Virtual SAN PHDVirtual, HP Lefthand VSA or StarWind iSCSI.
