  Hello-

  You're not quite call things correctly.  There are 2 two different things you need to do:

  1. "point source" the .ps1 file in which the function is defined by doing something like: ".." c:\temp\functionDefinitionfilename.ps1 ".
  2. _then_, you must call the function name (not the name of the .ps1 file) and can pass parameters (such as "Get-VNVMHostLogicalVolumeInfo - VMHostName myvmhost0.dom.com"

  To article 0, you _must_ include the period and the space before the name of the file in which the function is defined.  This action is what makes the "Get-VNVMHostLogicalVolumeInfo" function available in your PowerShell session.  It is the "supply point".

  Then, for question 1, which is the function name, "Get-VNVMHostLogicalVolumeInfo", not the name of the definition of the function (the .ps1 file) file.  Until you do these two things, you will continue to get zero results.  You follow?

  It depends on what you want to achieve. Fault tolerance, the aggregation?

  Take a look at this document from VMware.

  If you use your search engine of the day and throw it into the words "VMware ESX" and add circuits or consolidation, there will be some hits on various blogs showing solutions to different hardware (in collaboration with Cisco, HP switches).

• Best practices for storing the Logs of the system for all newly improved ESXi hosts?

  Hi people,

  What are the options and best practices for the Logs of the system for all newly improved 5.1u1 ESXi hosts?

  Do I need to have the Syslog server or it can be safely ignored?

  Thank you

  Evening,

  Syslog is preferred, but VMware has provided a collector of syslog on the vcenter installation disc can be installed on any windows host or your vcenter. I can't count the number of times where I had guests CMTF or newspapers lost... Fortunately for the syslog which collects up to the accident.  It is not necessary, but it's really a good idea without any real cost since you can use your vcenter host.

  Here is an article on how to install it:

• Best practices for backup of vCenter device and ESXi hosts?

  Hello

  I have a new VMware environment based on 5.5 ESXi and vCenter Server Appliance. A few questions:

  • What is the best practice to perform the backup of the vCenter Server Appliance? I set up the camera with the embedded SQL Express database.
  • It's recommended to backup the ESXi host or is it easier to any re - install failure?

  Best regards

  Hello

  You can use VMware VDP to backup your device of vCenter. It is included in essentials, standard, enterprise, and enterprise as well as licenses.

  I won't have backups of ESXi servers. Restore the backup would take more time that the deployment of a new ESXi.Only thing, you may want to consider is to enable logging remotely, so you can see why the hosts failed.

• best practices for the deployment of resiliency using a single ESXi host

  I was wondering if anyone had some advice or a deployment guide for ESXi in an environment without using a cluster. If the cost was not a factor I'd put it in a pool, but this can be done. So, assuming that it is an ESXi host with multiple network cards, which would be a good way to cover areas such as backup and restore when you use the free version? The machines that would go on is not mission-critical if there is a pretty good time that machines could be down without causing problems, however, I want to be sure that if the machine were to explode then there will be a way to recover the virtual machines running on this subject.

  Ideas?

  I think, there is no better practical form VMware vSphere Hypervisor (free version) use, but maybe you'll find some ideas here: How to get VMware cost barriers - build an empire around the free VMware hypervisor

• Best practices ESXi Install/Config

  Hi all, first of all I am noob VMware, my apologies. I tested Esxi internal 4 in recent months. Without going into details, I would like to adopt the solution Dr. Esxi 4. We are a small company with a large parent company that can provide the space for the equipment and the employee must strike DR.

  I would buy a sever adaquite to deploy three virtual servers which would be W2k3 or W2k8. One would be a file server / print, the other an Exchange 2007 server and the last would be a server terminal server. Looking for a guide or a best practice document that talks about the allocation of memory/recommendations, equipment practices, sharing practices, etc... For example I want to go with a configuration Raid 5 vs Raid 1 or Raid 1 + 0. During the installation of w2k3 would I created a partition c:\ and d:\... Etc...

  If any of you have recommendations or guidelines that you can share with me, it would be greatly appreciated.  Thanks in advance to all!

  If it is strictly intended to DR, I suppose that high performance is not what you need in the first place.

  Then I'd go to a server with 1 CPU Quad Core 2.5 GHz or more, at least 8 GB RAM 2x300GB SAS HDD as RAID1, make sure you have a RAID with battery buffered controller cache write (otherwise you won't be very happy). Make sure that the server and the components are the VMware HCL

  The servers will run probably with 2 GB of RAM, but ESXi will have too little RAM.

  Configure the virtual machine as you would with physical HW.

  For Windows 2003, you can partition alignment.

  EDIT: Please use only 1 vCPU per VM.

• Best practices for the management of user access in ESXi host without 'root '.

  What is the best way to make the management of the user access to the ESXi host after you disable the default root account. Is it better to create induvidual accounts

  Via vCenter or intergrate Active directory or any other specific way.  Please help me to clarify this point. Thanks in advance for your answers.

  With the release of ESXi 5.1 it is possible to create an account on the ESXi host and assign them Full Admin privileged but there are a lot of admins of loggin in each ESXi host and user account creation.

  I would like suggestions to add the ESXi to AD and add the authorization based on domain accounts.

• New to ESXi ESXi installation USB or local disks operation best practices?

  I'm new to Vmware and run a small store, what is the best practice or best method to install the OS ESXi.  I currently have a few that I have installed on the usb stick on the server Board.  After some research it would be better to have two small drives SSD that I can raid with the operating system, then another RAID for the VM data store.  USB is a single source of failure.

  Thank you

  Mike

  Hello

  Having the internal hard drives in RAID1 for the o/s will certainly to avoid a single point of failure, as you pointed out correctly. At present the death of your USB key, your host problems quite quickly, and you will need to get a new one and re-install again. You could save your good host configuration and realistically - it does take too long to rebuild a crowd if he dies. Lose other stuff like network configurations and others would however be a pain!

  I think I have two SSD internal drives in RAID1 for the o/s is probably overkill. You will have an advantage any speed of startup, but realistically most of the servers restart everything often and once that ESXi is in place and operational it is very little activity on the disks, a config updates every so often and so on. I'd be inclined to use a SSD to create a Cache of the host for the swap drive, like that you can actually use the SSD and get more performance for your money.

  Many manufacturers (like Dell) use internal SD cards in RAID1. While SD cards are not known to be very robust, because of the congestion of ESXi and the minimum number of necessary paperwork once installed initially, it makes a less expensive alternative to business class for the o/s disks.

  In regards to your data warehouses, having an internal RAID your local disks is best if you use a stand-alone host with no storage attached to the network. You always have the problem of failure of the host if.

  See you soon,.

• Best practices for network configuration of vSphere with two subnets?

  Well, then I'll set up 3 ESXi hosts connected to storage shared with two different subnets. I configured the iSCSI initiator and the iSCSI with his own default gateway - 192.168.1.1 - targets through a Cisco router and did the same with the hosts configured with its own default gateway - 192.168.2.2. I don't know if I should have a router in the middle to route traffic between two subnets since I use iSCSI ports linking and grouping of NETWORK cards. If I shouldn't use a physical router, how do I route the traffic between different subnets and use iSCSI ports binding at the same time. What are the best practices for the implementation of a network with two subnets vSphere (ESX host network: iSCSI network)? Thank you in advance.

  Install the most common iSCSI would be traffic between hosts and

  the storage is not being routed, because a router it could reduce performance.

  If you have VLAN 10(192.168.1.0/24) iSCSI, VLAN 20 (192.168.2.0/24) ESX

  MGMT and VLAN 30 (192.168.3.0/24) comments VMs and VLAN 40 (192.168.4.0/24)

  vMotion a deployment scenario might be something like:

  NIC1 - vSwitch 0 - active VMK (192.168.1.10) MGMT, vMotion VMK (192.168.4.10)

  standby

  NIC2 - vSwitch 1 - current (VLAN30) guest virtual machine port group

  NIC3 - vSwitch 2 - active VMK1 (192.168.1.10) iSCSI

  NIC4 - vSwitch 2 - active VMK2 (192.168.1.11) iSCSI

  NIC5 - vSwitch 1 - current (VLAN30) guest virtual machine port group

  NIC6 - vSwitch 0 - MGMT VMK (192.168.2.10) standby, vMotion

  VMK (192.168.4.10) active

  You would place you on VLAN 10 storage with an IP address of something like target

  192.168.1.8 and iSCSI traffic would remain on this VLAN. The default value

  gateway configured in ESXi would be the router the VLAN 20 with an ip address of

  something like 192.168.2.1. I hope that scenario help set some options.

• Roles, permissions - DataCenter, file, Cluster, host Layout - best Practices\How-to

  Have a little problem with permissions and roles. I'm sure it will be an easy one for those of you with more experience of working with roles. I hope that my layout organization made with quote boxes is readable.

  The Organization has just spun a new host ESXi 4 for developers and added in vCenter. Developers want to use the vSphere Client\VIC to manage the ESX Server. They need rights to create virtual machines, remove VMs, clone VMs, VMs potential power. However, we don't want them to be able to reach production.

  According to the diagram below, the new host of development, labeled as "HostC (autonomous DEVELOPMENT host)", is located under "Data Center-City-2", who also owns the production ESX clusters. " And obviously I don't want developers having rights on production groups.

  Lets say I have create a role called 'HostC Dev Sandbox Rights', add users and assign directly to "HostC" below. This role contains the VM 'create' right, however when I run the wizard Creation of VM of HostC as a member of the role the vSphere Client tells me this task requires rights create VM on the level of data center! But given these developers to create VMS access on the data center would give them rights to create virtual machines in the poles of Production! Which is obviously a problem.

  I can't believe that our need to give these rights to ONLY one host in a DataCenter is rare. I don't know that there is a misunderstanding on my part of how to configure VMware roles for best practices.

  Anyone with more expirence on VMware roles ready to help me on this one? Thanks in advance!

  Many cases, clusters, hosts

  You can apply permissions directly to the data store.  I didn't need to go further than the clusters in our environment, but what really works for you is to place data warehouses in folders for storage.  Have the records be the names of your groups hosts and clusters.  Then place the warehouses of data for each cluster in the corresponding folder.  Then, just apply permissions for the data on the record instead of warehouses in each individual data store.  Off topic a little, but a records of something in the store of data discovered lack is the function of "views of storage" and I put a future application.

  Yes, if you set permissision to the view of the data store the user can turn opinion and see.  Extensive your permissions framework tests is guaranteed before pushing users.  Looks like you are already doing.

• Best practices for vsphere 5.1

  where can I find the doc more up-to-date about berries EQL configuration / best practices with vmware vsphere 5.1

  Hello

  Here is a link to a PDF file that covers best practices for ESXi and EQL.

  Best EqualLogic practices ESX

  en.Community.Dell.com/.../20434601.aspx

  This doc mentions specifically that the storage Heartbeat VMKernel port is no longer necessary with ESXi v5.1.  VMware has corrected the problem that made it necessary.

  If you add it to a 5.1 system it will not hurt.  It will take an IP address for each node.

  If you upgrade 5.0 to 5.1, you can delete it later.

  Here is a link to VMware which addresses this issue and has links to other Dell documents which confirm also that it is fixed in 5.1.

• The ESXi 4.1.0 to 6.0 upgrade. -upgarde and best practices

  Hi guys,.

  We are a small business with a single physical server, ESXi 4.1.0 installed with approx. 8 VMs. We plan on buying Essential Kit 6.0 ESXi because that's all we need right now. However, as VMWare says that 4.1.0 to 6.0 upgrade is NOT supported (matrices of the interoperability of products VMware), how we improve our host and VMS?

  I guess the correct way will be upgraded from 4.0. 5.5 U3 first, then to 6.0. However, if we buy the 6.0 license essential Kit, that we will be able to always download and install and upgrade of the host and all VMs to U3 5.5, and 6.0. Essentials?

  In addition, what are the best practices to upgrade a single host with multiple virtual machines? What I did research, we should back up important files from virtual machine, all critical data, etc. All recommendations are welcome. My understanding is that the upgrade also virtual machines will be upgraded automatically, that's correct - methods of upgrade to ESXi 5.5 (2058352) | VMware KB

  Best regards

  Hello

  As you said, you cannot upgrade host ESXi 4.x to 6.x, you must first upgrade 4.x to 5.x and then switch to 6.x

  Before moving to 5 or 6, make sure you ESXi host is compatible with ESXi 6.

  Check cheque and VMware hardware compatibility list if your server is listed.

  Although you'll have a 6 ESXi license kit, you can download ESXi 5.x and use it to upgrade process.

  Only if you need to use 5.x permanently, then you need to get your license keys downgraded to 5.x, otherwise once you upgrade host to 5.x, go ahead and level to ESXi 6.x

  Backup-

  Before you begin the upgrade, make sure that you have backup of all VMs critics.

  Either you can download/export all VMs as OVF, or you can use Veeam's free edition to make the backup of virtual machines

  -Update

  You can join the server ESXi ISO Installer and boot server form ISO and update.

  During the Installation process make sure to select ' PRESERVER VMFS and upgrade ESXi host '

  If you do not keep vmfs, all virtual machines will get deleted during the installation/upgrade process.

  Once you get ESXi Host upgrade to Upgrade VMFS 5.x version so that it can support 6.

  Then finally the ESXi host to 6.x upgrade, yet once make sure PRESERVE you VMFS during installation.

  If you have vCenter Update manager, use update reach the average upgrade easy it is to upgrade.

  Thank you
