• Help, I changed the password of root ESXi via powerCli, now I can not connect with the web client or the console.

  Help, I've changed the root ESXi via powerCli password, now I can not connect with the web client or the console, but I can still connect to powerCli. The command I used was;

  SE connect-VIServer esxihostname-user root - password newpasswd

  This production network btw, I have connected to each host and run the above command, these ESXi hosts are not on a domain

  y at - it something I have left out. I really appreciate any assistance that you people can provide.

  Thank you, Joe

  It is probably a longshot, but a lot of things in the land of windows is not sensitive to capital letters as Unix is.  I wonder if your new password you put through powerCLI mixed uppercase in it and if the capitalization was abandoned by command windows powerCLI Analyzer, or he interpreted as all capitals or something.   If you can still get through the powerCLI you could try to reset the password again to something simple without capitalization mixed case and if your password on ESXi strategy requires a special character, try something different than a "$", like a "_" (I find that a '_' is less likely than some other special characters (, as a '-' or a ' / ' to cause problems with analyzers.).

  Edit:

  Another thing, you can try before playing with the password once again, is to create a different username ESXi using powerCLI and see if the password ends up what you think, it should be, and if you can get with the client vsphere using it.  In this way, you can find out if there are some problems with certain characters or Cap through command powerCLI Analyzer without losing your remaining root by powerCLI access.  After some tests, you can understand what went wrong with your initial password change and may be able to fix it with less risk of losing access.  I also assume that you can not create a new username on ESXi who is able to change the root password no matter what authority give you it, otherwise, you could create a new username with PowerCLI, then connect to the client vsphere with it and change the password to root from there.

• Fully automate the addition of a datasoter via PowerCLI

  I have a need to be able to completely automate the addition of a new data store to a new installation of ESXi via powerCLI.  My problem is I want to have this fully automated and be able to enforce it against any box without user intervention, which means that I need a way to return the CNAME of the ScsiLun in new-store data command.

  I am currently using the command to run my action you want below, but for some reason, it does not.

  $con = get-ScsiLun | Select-object CanonicalName

  New data store - VMHost 192.168.1.1 - name newDS-path $con - Vmfs - BlockSizeMB 1

  The above returns the above error

  Although below works very well.

  new data store - VMHost 192.168.1.1 - name dvms-path naa.600508b10010395659503152424f0100 - Vmfs - BlockSizeMB 1

  I also tired the Deputy bud did not work

  $test = get-datastore. Select-Object - 1 first

  new data store - VMHost 192.168.1.1 - name dvms-path $test - Vmfs - BlockSizeMB 1

  Help or direction would be greatly appreciated.

  Thank you

  The Select-Object cmdlet does not return the name of the LUN as a string, but as a ScsiLunImpl object.

  The New-Datatsore cmdlet requires a string for the - Path parameter.

  You can do

  $con = (Get-ScsiLun).CanonicalName
  New-Datastore -VMHost 192.168.1.1 -Name newDS -Path $con -Vmfs -BlockSizeMB 1

• How to calculate the IOPS datastore / s and latency via Powercli?

  Hi all!

  I want to calculate the IOPS / s (RO/RW) and the latency of the data via Powercli store, but I cant' find this metric in Vcenter (in the data store tab) and see no metric for data via the cmdlet Get-Stat store.

  How can we measure IOPS / s and latency of data store?  For example I know veeam monitor this information - http://cdn.swcdn.net/creative/v16.8/images/screenshots/products/VM/Lg/EN/VMan60-Orion-Datastore-Top_Lg_960x540.jpg

  I know, I can get this VM or vmhost metric, but I need information on the data store.

  How to measure for IOPS / s and latency of data properly store?

  Thanks in advance!

  These measures are collected on ESXi nodes, entity would need to have the ESXi nodes where these data warehouses are connected.

  You can use the Instance property to filter.

  Under the PerformanceManager , you see all the measures for each indicator it indicates under which entity this metric is collected.

  

  And Yes, the cmdlet Get-inventory returns no data warehouses.

  There is a little, aggregated metric for data warehouses, I'll have to find an alternative for those.

  Nice catch!

• How to calculate the CPU Ready on Cluster DRS via Powercli?

  Hi all!

  I have a DRS Vsphere cluster. I want to know what is the value of the loan of CPU I have in my group.

  For example, I get 20% of powercli value, it is normal for the cluster, but if I have 100% or more, I have a problem.

  How to achieve via Powercli? And how to calculate the percentage values correctly?

  I know, I can get all values of CPU Ready of VMs cluster, but IT is not the same thing, I need overall value of CPU Ready.

  Thanks in advance!

  As far as I know you can get the cpu.ready.summation for ESXi nodes or VMs.

  For a cluster, you will need to get the value of each node in the cluster ESXi and then take the average.

  The metric cpu.radey.summation is expressed in milliseconds.

  To get a percentage, you need to calculate the percentage of loan period during the interval during which it was measured.

  Something like this (this will give the loan current %)

  $clusterName = "mycluster.

  $stat = "cpu.ready.summation".

  $esx = get-Cluster-name $clusterName | Get-VMHost

  $stats = get-Stat-entity $esx - Stat $stat - Realtime - MaxSamples 1 - forum «»

  $readyAvg = $stats | Measure-object-property - average value. Select - ExpandProperty average

  $readyPerc = $readyAvg / ($stats [0].) IntervalSecs * 1000)

  Write-Output "Cluster $($clusterName) - CPU % loan $(' {0:p}'-f $readyPerc).

• Cultivate a disc of virtual machines via PowerCLI

  Hello

  I'm looking to cultivate a few volumes on some servers via PowerCLI. I got the code to extend successfully the volume inside the prompt below OS once I increase it configured size through the user interface.

  Hard drive get "name VM | where {$_.} {Name - eq ' hard disk 2 "} | Together-hard drive - CapacityGB 20 - ResizeGuestPartition-confirm: $false

  My question is:

  Is it possible to increase the size put in service of a disk via PowerCLI I could run before the above code that extends the volume inside the guest OS?

  Thanks in advance for any help!

  As each correct answer, I'll have to start with "it depends".

  If this isn't the vdisk that contains the system partition, you can simply use the hard drive Set cmdlet with the CapacityGB parameter. See example 2.

  If it is the system partition vdisk, you need to use the parameter HelperVM of the cmdlet Set - hard drive .

  Note that the virtual machine and the HelperVM both must be switched off!

• Managind DRS groups via powercli

• The host system resources / booking via PowerCLI

  Hello chaps,

  Does anyone know if it is possible to adjust the CPU and the memory that is reserved for a host via PowerCLI?

  (Home > Configuration > Allocation of system resources > edit)

  I usually affect the reserve memory 800 MB and CPU 800 MHz according to the design best practices.

  Thank you

  
  Dan

  As far as I know, there's no cmdlet for this, but you can use the UpdateSystemResources method.

  You just need to know that the key to the Scriptures "host/system".

  $esx = Get-VMHost MyHost 
  
  $spec = New-Object VMware.Vim.HostSystemResourceInfo $spec.key = "host/system" $spec.Config = New-Object VMware.Vim.ResourceConfigSpec$spec.Config.cpuAllocation = New-Object VMware.Vim.ResourceAllocationInfo$spec.Config.cpuAllocation.reservation = 800$spec.Config.memoryAllocation = New-Object VMware.Vim.ResourceAllocationInfo$spec.Config.memoryAllocation.reservation = 800$spec.Config.ChangeVersion = $esx.ExtensionData.SystemResources.Config.ChangeVersion

• Disable the host followed via PowerCLI

  Hi all...

  
  I am looking for a way to disable the host followed via powercli.

  I found one-liner of LucD to get the current state: Get-Cluster | Select Name, @{N = 'Home monitoring status'; E={$_. Extensiondata.Configuration.DasConfig.HostMonitoring}}

  And I know how to turn on/off HA: Get-Cluster | Cluster - HAEnabled game: $false

  But I'm not sure how to combine the two.

  I want to be able to quickly toggle host control without having to disable HA altogether.

  Thoughts?

  Thank you!

  You can use a where clause

  Get-Cluster | where {$_.} Extensiondata.Configuration.DasConfig.HostMonitoring} | Cluster - HAEnabled game: $false

• VMware tools take it apart or modify the parameters of CD-Rom via PowerCLI

  After the upgrade invited on Redhat Linux vmware tools vmware tools remain in the properties of the vm.

  I mean that the device vm: CD-Rom drive is configured to store data-ISO file [/vmimages/tools-isoimages/linux.iso]

  The CD-ROM drive is not connected!

  I can't Vmotion of such systems.

  Is there a way to define the type of device clientcdrom to 'clientdevice' via PowerCLI?

  I checked some commands powercli: set-cddrive, dismount-tools

  
  

  With the powerclie cmd:

  Get - vm GuestName | Get-cddrive

  I am able to locate systems that have the problem.

  Output:

  Hi, George,

  I think NoMedia - Set-CDDrive switch, it's what you need - it Peel host device or iso file.

  Get - VM | Get-CDDrive. Game-CDDrive - NoMedia-confirm: $false

• Can RV082 password lost, I get my backup configuration file.

  I forgot my rv082 of admin password, but I have a backup configuration. password can be decoded to him?

  Thanks for any help!

  No one really knows what information is in the backup file. In general, are stored passwords that do not need to be transferred elsewhere encrypted and cannot be decrypted. Most likely, you need to reset your router to the factory settings. But you can try asking your question in the support community Cisco Small Business for routers. The RV082 is now part of Cisco Small Business and there is few people Cisco who can check with the developers...
